Maker / Sky (MKR/SKY)
Overview
Maker/Sky is a pioneer DeFi protocol originally launched as MakerDAO, now rebranded as Sky Protocol. It issues the DAI stablecoin (upgrading to USDS) backed by overcollateralized crypto assets and real-world assets (RWA). The protocol has allocated over $2.5B to tokenized real-world assets, primarily US treasury bonds, making it one of the largest onchain holders of traditional financial instruments.
The protocol underwent a major rebrand from MakerDAO to Sky Protocol, converting the MKR governance token to SKY at a 1:24,000 ratio. Q1 2026 was Sky Protocol's strongest quarter on record: gross protocol revenue $123.79M (+28.9% YoY, +56.8% QoQ), net protocol surplus $46.04M (vs. -$13.51M loss in Q1 2025), USDS + DAI supply $11.70B (+67.9% YoY), and protocol collateral $13.03B (+49.1% YoY) (Sky Frontier Foundation Q1 2026 Quarterly Report). sUSDS deposits grew 71.7% QoQ to $6.49B, making it the largest yield-generating stablecoin by supply. Binance, Bitget, Gate, HTX, KuCoin, and MEXC have announced or initiated DAI → USDS migrations. On March 14, 2026, governance approved a capital restructuring that cut the SKY buyback allocation from 75% to 7.5% of net profits, redirecting revenue toward a $150M solvency reserve target (currently $50.90M, projected ~$75M by end of Q2 2026 per SFF). Once reserves reach the target, allocations restore to 50% reserves / 25% buybacks / 25% staking.
Primary Use Cases
- Stablecoin Issuance: Mint USDS/DAI by depositing overcollateralized crypto and real-world assets
- Savings & Yield: Sky Savings Rate offers 4.5% yield on USDS deposits
- RWA Tokenization: $2.5B+ allocated to tokenized treasury bonds generating real yield
- DeFi Lending: Spark Protocol serves as the primary lending frontend for the ecosystem
Capital Strategy Restructured (March 2026): Sky Protocol generated $123.79M in gross revenue and $46.04M in net surplus during Q1 2026 (the strongest quarter on record). Governance slashed the SKY buyback allocation from 75% to 7.5% of net profits on March 14, 2026 to redirect revenue toward a $150M solvency reserve target (currently $50.90M, projected ~$75M by end Q2 2026 per Sky Frontier Foundation). The plan is structured in three stages: (1) current = majority of net surplus to reserves, buybacks reduced; (2) reserves growing toward target; (3) full restoration to 50% reserves / 25% buybacks / 25% staking once the $150M target is hit. SKY staking distributions remain at full rate throughout (funded from reserves, not buybacks). This is a deliberate pivot from short-term holder distribution to long-term protocol resilience, the opposite direction of protocols like Uniswap and Aave that recently activated or expanded holder cashflow.
What matters most right now
As of April 2026- USDS + DAI supply $11.70B and Sky Lending TVL $12.46B end of Q1 2026 (Sky Frontier Foundation Q1 2026 report; broader scope than DefiLlama's narrower core-market figure of ~$5B because SFF includes Sky Agent Vaults + PSM Vaults, see scope note below). Category-defining stablecoin+CDP protocol, 7+ years of operational track record.
- Aggregate Backstop Capital (ABC) reserve build-out post-March 2026 restructuring positions Sky for structural resilience across credit cycles, moves the protocol away from holder distribution toward long-term capital adequacy (opposite direction of most competitors).
- Dual-token model: DAI (legacy, $4.66B supply) + USDS (new, primary, $8.73B) at 1:1 convertibility (DefiLlama stablecoins, 2026-05-11). Preserves backward composability while migrating to the new brand.
- Structural fee-burn on MKR via surplus auction remains active (though allocation slashed, see bearish), providing ongoing (reduced) buyback pressure.
- Critical: SKY buyback allocation slashed 75% → 7.5% on March 14, 2026 (TI Research Changelog). Most of what was the value-accrual thesis for SKY/MKR holders has been redirected to the ABC reserve. This is a deliberate move away from token-holder distribution, opposite of the direction Uniswap/Aave went. Restoration to the full allocation framework (50% reserves / 25% buybacks / 25% staking) requires the reserve to reach $150M (currently $50.90M, projected ~$75M by end Q2 2026 per Sky Frontier Foundation).
- USDS-only circulating + sUSDS + stUSDS at end of Q1 2026 is ~$8.22B, with DAI adding ~$4.65B for combined $12.87B in stablecoin obligations (Sky Frontier Foundation Q1 2026 Balance Sheet). The dual-token model is mechanically functional but adds an extra unit of accounting that institutions have to translate.
- Endgame / Sky Agent complexity continues to add governance surface area: 5 active Agents (Spark, Grove, Keel, Obex, Skybase) with 5 more expected to launch in 2026. MKR→SKY conversion ratio 1:24,000 is mechanically clean but adds retail-comprehension friction.
- Protocol revenue is strong ($123.79M Q1 gross, $46.04M Q1 net surplus), but the question "who captures it" has been reframed post-March 2026, answer is "the protocol's reserve," not "SKY holders", until reserves cross the $150M target and the full allocation framework restores.
Reserve build-out velocity vs. the $150M target, at $50.90M end of Q1 2026, projected ~$75M by end Q2 (per Sky Frontier Foundation forecast). Each quarter that reserves grow faster than projected pulls forward the date when buyback allocations restore. If reserves are at or above $150M by end of Q4 2026, the restructuring thesis is validating cleanly. Combined USDS+DAI supply growth (currently $11.70B, +67.9% YoY) is the leading indicator for whether institutional adoption is feeding the revenue that funds the reserve build-out.

Q1 2026 quarterly snapshot (Sky Frontier Foundation)
Source: SFF Q1 2026 Quarterly ReportQ1 2026 was Sky Protocol's strongest quarter on record. Gross protocol revenue, net surplus, and USDS+DAI supply all set new highs, and the protocol exceeded the Sky Frontier Foundation's base projections across every key metric (gross revenue +12.3%, net revenue +87.4%, net surplus +79.8% vs. forecast).
Sky Protocol Quarterly Revenue, Q1 2025 → Q1 2026
Gross Protocol Revenue (light blue bars) · Net Protocol Revenue (dark blue line)
Key Metrics, Q1 2025 → Q1 2026
| Protocol Metric | Q1 25 | Q2 25 | Q3 25 | Q4 25 | Q1 26 |
|---|---|---|---|---|---|
| USDS + DAI Supply ($B) | 7.9 | 7.1 | 7.8 | 9.2 | 11.70 |
| Unique Holders | 519,524 | 532,008 | 551,089 | 581,990 | 680,170 |

| Sky Lending TVL ($B) | 10.1 | 10.7 | 12.5 | 11.9 | 12.46 |
Implications for the SKY thesis: revenue and supply are accelerating into the buyback restructure, not despite it. The $150M reserve target is the gating variable for when buybacks restore. At ~$25M/quarter reserve build (the Q1 implied rate), reserves hit target in roughly Q4 2026, though SFF's own projection of ~$75M by end Q2 suggests the rate is faster than that linear extrapolation. The earlier the target hits, the earlier the value-accrual mechanism for SKY holders re-activates. Net Protocol Revenue margin expanded from 30.24% in Q4 2025 to 49.06% in Q1 2026, indicating the protocol is becoming more efficient as it scales (cost of capital dominated by SSR payments to sUSDS depositors, controllable opex stable at ~$2-3M/quarter).

Sky as a credit issuer: balance-sheet lens (May 2026)
Source: Block Analitica / Blockworks ResearchMost coverage of Sky still describes it as the third-largest stablecoin issuer. A more useful frame at this scale is the one a bank credit analyst would use: Sky writes liabilities (USDS, DAI), pays yield to attract deposits, and lends the proceeds out through a small set of independent capital allocators. The relevant questions stop being "is the peg holding" and start being "what is the loan book, who underwrites it, and how thick is the cushion if it sours."
Asset side (May 10, 2026)
Against ~$12.6B of stablecoin obligations, Sky holds ~$15.9B of gross collateral, a 126% system-wide coverage ratio. About 31% of obligations are matched 1:1 by USDC sitting in the Peg Stability Module, which functions as Sky's high-quality liquid asset reserve (and quietly earns yield via Coinbase Prime's USDC yield-share). The remaining 69% funds a concentrated loan book intermediated by three Agents.
Loan book by allocator
| Allocator | USDS Debt Outstanding | Share of Loan Book | Collateral Coverage | What it Deploys Into |
|---|---|---|---|---|
| Spark | $4.20B | 53% | 107% | SparkLend, DeFi venues, institutional lending channels |
| Grove | $3.13B | 39% | 104% | Institutional credit, tokenized RWAs |
| Obex | $608M | 8% | 142% | Incubator for external allocators (Maple, Securitize, Centrifuge, USD.ai, Daylight, River, TVL Capital, Better) |
| Sky-direct (PSM) | n/a (USDC-backed) | 31% of total obligations | 156% | 1:1 USDC reserve; functions as HQLA |
The sharp point: the largest allocator runs the thinnest cushion. Spark holds 53% of the loan book at 107% coverage. Grove (39% of the book) sits at 104%. The 126% headline coverage is carried by the PSM and Obex; the two allocators with most of the deployed risk are within 4-7 percentage points of par. If collateral marks down meaningfully and Sky-direct/Obex cannot absorb the loss through their own buffers, the Aggregate Backstop Capital reserve build is what stands between an Agent shortfall and a hit to USDS holders. That reframes the ABC target ($150M, currently ~$51M) from a buyback-restoration timer into a credit-buffer adequacy question.
Net interest margin compression
Sky generated roughly $33.2M in average monthly gross interest income over the six months ending May 2026, with net interest income running in the $10-15M/month range after SSR payments to sUSDS depositors. Annualized net interest margin compressed from ~1.6% to ~1.3% across that window. The mechanism is straightforward: deposits grew faster than Agent redeployment, and the marginal deposit dollar earned the SSR before it earned a productive spread. This is the cost of the growth-at-all-costs phase, and it should reverse when Agent deployment catches up, assuming attractive spreads still exist by then.
SSR vs DSR migration is doing its job
Of the USDS supply, ~70.5% sits in the Sky Savings Rate (sUSDS) at a current rate of 3.65%. Of the legacy DAI supply, only ~5.5% sits in the Dai Savings Rate (sDAI) at 1.25%. The 240-bp gap is policy: Sky governance keeps DSR low to incentivize holders to migrate from DAI to USDS, and the deposit-share data shows the migration is largely complete on the USDS side. Even after the SSR was cut 110 bps from its Q4 2025 peak of 4.75%, the share of USDS supply locked in sUSDS rose from ~50% to ~70.5%, which suggests yield stability matters more than the headline rate for the buyer Sky has attracted.
Read-through for the SKY thesis: the protocol-level equity ratio sits near 0.5% of obligations, which sounds dangerously thin if you read Sky as a stablecoin issuer. Reframed as a credit system, the real loss-absorption layer is the 126% gross collateral coverage plus the still-building ABC reserve. The risk is not the headline equity number; it is whether Spark and Grove can keep coverage above par as the loan book scales and as Agents reach into longer-duration, lower-liquidity collateral. Each Obex cohort that activates external allocators (Maple, Centrifuge, USD.ai, etc.) adds underwriting diversification but also adds counterparties whose risk controls Sky governance does not directly enforce.

Programmatic value distribution: where the NII actually goes
Source: Sky Atlas + Blockworks ResearchThe balance-sheet section above explains how Sky generates roughly $161M in annualized net interest income across the three Agents plus the PSM yield-share with Coinbase Prime. This section explains where that NII goes once Sky finishes its transition to the fully programmatic distribution mechanism described in the Atlas. Two pieces matter: the waterfall logic, and the rate at which SKY holders actually receive cash today versus the steady-state design.
The waterfall (at-target steady state)
Sky's revenue distribution operates as a tiered cascade. Twenty percent of net revenue comes off the top for security and maintenance: 10% to the Core Council, 10% to the Fortification Foundation (currently routed to the Sky Frontier Foundation on an interim basis pending the Fortification Foundation becoming operational). The remaining 80% flows into an Aggregate Backstop Capital gate that withholds capital from passthrough whenever ABC sits below the $150M floor or below the 1.5% of USDS supply target. At target, the gate passes the full 80% to the Step 3 split, which routes 45% to SKY buyback for staker rewards, 45% to direct USDS staker rewards, and 10% to outright SKY burn. The 45/45/10 design gives stakers exposure to both legs of the protocol: 36% of NII flows to SKY-denominated yield (leveraged upside to protocol growth), 36% flows to USDS-denominated yield (stable cashflow floor), and 8% goes to permanent supply reduction that accrues to every holder.
The March 2026 buyback rate cut is the sharpest governance signal in this section
Sky has cumulatively retired 1.89 billion SKY tokens for $119M at an average price of $0.063 (roughly 8% of total supply). From November 2025 through mid-March 2026, the program ran at $275K per day, an annualized $100M, equivalent to more than 60% of Sky's current $161M NII run rate. In mid-March, governance approved an 87% cut to $36K per day. The reasoning is straightforward but worth naming: with the Surplus Buffer running negative because Genesis Capital was paid out to the SubProxies and NIM compressed from 1.6% to 1.3% as deposits outran Agent redeployment, governance chose to prioritize rebuilding the protocol-level safety net over near-term tokenholder yield. Once ABC crosses the $150M floor and approaches the 1.5% of USDS supply target, the waterfall above starts passing larger shares of NII through to stakers. The buyback-rate cut is the explicit signal that Sky governance treats ABC adequacy as a higher-priority capital allocation than current tokenholder returns.
Scenario yields: what stakers get under each Agent-growth trajectory
Blockworks Research published a three-scenario yield analysis in May 2026 that frames the forward staker return across bear, base, and bull cases. The variables are Agent debt outstanding, NIM, and what share of NII the waterfall passes through (a function of ABC adequacy). All three scenarios hold crypto-backed exposure flat at $615M, PSM USDC at 30% of total assets, and the Step 3 split fixed at 45/45/10.
The 10.2% base-case staker APR is the number an institutional reader anchors on. It assumes Agent debt grows roughly 50% from current $7.97B to about $12B, NIM holds at 1.3%, and ABC crosses the $150M floor but not the 1.5% target (so 60% of NII passes to stakers). Combining the SKY-denominated half with the USDS-denominated half plus the deflationary tailwind from the burn allocation, the base-case yield on Sky's total market cap is roughly 8%. The bull case (which requires Agent debt scaling to $18B, NIM expanding to 1.6%, and ABC crossing the 1.5% target so the full 80% passes) implies 24.8% staker APR or 19.4% on total market cap.
Three architectural details worth knowing
- Ecosystem Accord 1 codifies the Spark-Grove non-compete. Grove holds exclusivity on RWA allocations. Spark holds exclusivity on Maple, OTC crypto lending, and Established DeFi Lending Protocols (defined as protocols deployed six or more months ago, e.g., Aave and Morpho). Overlapping areas have codified revenue-sharing: USDe and sUSDe revenue is split 50/50 between the two Agents. The design avoids spread compression that would otherwise result from two allocators competing for the same yield opportunities.
- Subsidized Base Rate ramp through early 2028. Spark and Grove can each borrow up to $1B at a subsidized rate during a two-year window starting January 1, 2026. The rate ramps monthly from the T-Bill rate at month 0 to the full Base Rate of 3.95% by month 24. What Sky earns from its two largest allocators today is below run-rate by design. The spread normalizes mechanically by early 2028. Grove currently offsets a portion of this drag because Sky imposes a 30% income penalty for missing the July 2025 TGE deadline; the penalty continues until Grove launches its token.
- Loss-absorption waterfall is four tranches deep. Per-allocator over-collateralization absorbs first loss (Tranche 1). Then the protocol-level safety net: Surplus Buffer if positive (Tranche 2A), then Genesis Capital haircut pro rata across Agents up to ABC's full balance (Tranche 2B). Beyond that, the SKY Backstop mints and sells new SKY tokens on the open market to recapitalize (Tranche 3, uncapped per the Atlas). In an extreme left-tail scenario where losses still exceed what the SKY Backstop can absorb, Sky adjusts the USDS target price below $1, converting senior creditors into recapitalized equity holders via a 24 billion SKY airdrop (Tranche 4).

Investment Thesis
Maker/Sky's investment case centers on its position as one of the most profitable DeFi protocols, with substantial real-world asset exposure driving sustainable yield and aggressive token buybacks supporting price.
- $12.46B Sky Lending TVL + $13.03B total Protocol Collateral end of Q1 2026 (Sky Frontier Foundation). Top-tier DeFi protocol by collateral, recovered well off the $19.8B 2021 peak after the Sky rebrand and the Sky Agent Network buildout.
- ~$178M annualized DAO revenue from lending and RWA yield (DefiLlama sky-lending 30d run-rate, 2026-04-27)
- $102M+ in cumulative token buybacks since Feb 2025
- $2.5B+ RWA allocation in treasury bonds generating real yield. Obex Cohort 1 activated $1B deployment across 8 Sky Agents (Better, Maple, Securitize, Centrifuge, USD.ai, Daylight, River, TVL Capital)
- USDS + DAI combined supply at $11.70B end of Q1 2026 (+67.9% YoY per SFF). USDS-only is ~$8.22B (Circulating + sUSDS + stUSDS); DAI adds ~$4.65B. Binance announced DAI → USDS migration in early April 2026, with Bitget, Gate, HTX, KuCoin, MEXC following.
- SDEV (fka NovaBay, NASDAQ) accumulated ~8.78% of circulating SKY ($147M+), 100% staked
- Buyback program slashed 90%: On March 14, 2026, governance cut the SKY buyback allocation from 75% to 7.5% of net profits (~$37,600/day baseline). Staking rewards now funded from SKY reserves, not revenue. This is a deliberate shift from holder distribution to capital retention
- Capital restructuring underway: targeting $150M Aggregate Backstop Capital (ABC, raised from $125M per Atlas Edit weekly cycle, April 2026), up from ~$50.90M end of Q1 2026. Revenue now accumulates in reserves rather than flowing to token holders
- Rebrand confusion persists with dual tokens (MKR/SKY and DAI/USDS). Only 56% migrated to SKY
- Regulatory risk for stablecoins (USDS/DAI) across jurisdictions
- Complex governance structure with multiple sub-DAOs
- Justin Sun briefly became largest MKR voter, raising governance attack concerns
Key Catalysts

| Fixed-term Fixed-rate USDS Stablecoins (Sky Core Council exploration) | 2026 (announced Q1 2026 SFF report) | High. New product category for predictable-yield USDS holders. $5M subsidy pool to bootstrap early adoption. Parallel to Morpho Midnight in lending: industry-wide pivot toward fixed-rate institutional products. Could support longer-duration collateral strategies in Sky Agent Network. |
| Sky Reserves Reach $150M Target | SFF projects ~$75M end Q2 2026; full target Q4 2026 / Q1 2027 plausible | High. Triggers full restoration of allocation framework: 50% reserves / 25% SKY buybacks / 25% staking. The single most important variable for SKY holders' value-accrual return. |
| Full MKR to SKY Migration | Ongoing | High - Consolidates governance token, reduces confusion |
| Sky Agents Launch (5 more in 2026) | Q2 2026 onward; River expected to be 6th Prime Agent | High. Sky Agent Network at 5 active (Spark, Grove, Keel, Obex, Skybase) with 5 more expected in 2026 per SFF Q1 2026 report. Autonomous sub-DAOs expanding protocol functions across mortgages, GPU lending, energy infrastructure, etc. |
| $500M Tokenization Regatta (Solana RWA) | 2026 | High - Cross-chain RWA expansion via Keel |
| Obex Cohort 1 Activated | March 2026 | High, $1B USDS allocated across 8 capital allocators (Better, Maple, Securitize, Centrifuge, USD.ai, Daylight, River, TVL Capital). Most significant single deployment in protocol history. Diversifies revenue into mortgages, GPU financing, energy infrastructure, and other alternative credit. |
| Major Exchange DAI → USDS Migrations | April 2026 onward | High. Binance, Bitget, Gate, HTX, KuCoin, MEXC announced or initiated migrations. Industry-wide exchange upgrade consolidates liquidity around USDS. |

Before March 14, 2026, SKY was one of the strongest cashflow-to-holder stories in DeFi: 75% of $168M annualized profit directed to buybacks, plus 18%+ staking APY funded by protocol revenue. An eligibility-adjusted revenue multiple would have shown a competitive cost per $1 of forward cashflow.
That changed overnight. The buyback allocation was cut from 75% to 7.5% of net profits (~$37,600/day vs the prior ~$375,000/day pace). Staking rewards were decoupled from revenue and funded from finite SKY reserves instead. The vast majority of incoming USDS revenue now accumulates in the Aggregate Backstop Capital (ABC) reserve, strengthening protocol resilience but delivering near-zero direct value to SKY holders in the interim.
| Before March 14 | ~$126M/year to buybacks (75% of $168M). Strong ERM, competitive with HYPE/AERO. |
| After March 14 (Stage 0) | ~$12.6M/year to buybacks (7.5% of $168M). Staking rewards from reserves, not revenue. Effective holder cashflow dropped ~90%. |
| Stage 2 (future, post-ABC target) | 25% buybacks + 25% USDS to stakers + 50% retained. Would restore meaningful holder distribution, but the timeline to the $150M ABC target (raised from $125M per Atlas Edit weekly cycle, April 2026) is governance-dependent and unspecified. |
What this means for SKY holders. SKY is currently in the same category as LDO, MORPHO, and ENA: a governance token on a profitable protocol where the profit does not reach holders at current parameters. The difference is that Sky governance chose this deliberately as a temporary restructuring, with a stated plan to restore distributions once the Sky Reserves reach the $150M target (currently $50.90M, ~$75M projected by end of Q2 2026 per SFF). A reader long SKY today is betting that (a) reserves reach $150M on a reasonable timeline, (b) governance follows through on the restoration plan (50% reserves / 25% buybacks / 25% staking), and (c) the USDS+DAI combined supply growth (Q4 2025 $9.2B → Q1 2026 $11.70B per SFF metrics, +27% in one quarter) holds up. All three are credible but none are guaranteed.

Token Holder Rights
MKR token holders have full governance control over the Maker Protocol and benefit from automatic MKR burns when the protocol generates surplus revenue.
Rights Breakdown
| Right | Mechanism | Current Value | Sustainability |
|---|---|---|---|
| Staking Rewards | No direct staking mechanism | N/A | ◐ N/A |
| Governance Voting | On-chain voting via MKR | Full protocol control | ✓ Structural |
| Surplus Auctions | Protocol surplus buys/burns MKR | Automatic when surplus > buffer | ✓ Organic |
| Debt Auctions | MKR minted to cover shortfalls | Dilution risk in emergencies | ⚠ Risk |
How Value Flows to Token Holders
- Surplus Auctions: When protocol revenue exceeds the surplus buffer, excess DAI is used to buy and burn MKR on the open market.
- Governance Power: MKR holders vote on all protocol parameters including stability fees, collateral types, and risk parameters.
- Protocol Revenue: Stability fees from DAI loans and liquidation penalties flow to the protocol surplus.
- Debt Backstop: MKR holders accept dilution risk - new MKR can be minted in debt auctions during protocol shortfalls.
Sustainability Assessment: MKR has a sustainable value accrual mechanism through surplus auctions that buy and burn tokens using organic protocol revenue. However, holders accept dilution risk as MKR can be minted during debt auctions to cover protocol shortfalls.

Technology
Overcollateralized Lending
The core mechanism of Sky Protocol is overcollateralized lending: users deposit crypto assets or RWA-backed tokens as collateral and mint USDS or DAI stablecoins against them. The system maintains a collateralization ratio above 100% to ensure solvency even during market downturns.

| ETH / WETH | Native Ethereum collateral | Major |
| WBTC | Wrapped Bitcoin | Significant |
| RWA (Treasury Bonds) | Tokenized US treasuries, $2.5B+ allocated | Largest category |
| Stablecoins (USDC, etc.) | Peg Stability Module (PSM) | Moderate |
| Other DeFi Tokens | Various ERC-20 assets | Minor |
Key Protocol Components
- Sky Savings Rate (SSR): 4.5% yield on USDS deposits, attracting capital and stabilizing peg
- Spark Protocol: Primary lending frontend for borrowing USDS against collateral
- Horizon: Institutional RWA platform for tokenized asset access
- Peg Stability Module (PSM): Maintains USDS/DAI peg through stablecoin arbitrage
- Endgame Framework: Long-term protocol architecture with autonomous Sky Agents (sub-DAOs)
RWA Pioneer: Sky Protocol is the largest DeFi holder of tokenized real-world assets, with $2.5B+ allocated primarily to US treasury bonds. This provides sustainable, real-world yield that backs the USDS stablecoin.
Ecosystem
Sky Ecosystem Architecture (Q1 2026)
Three layers around Sky Protocol: SKY token (governance + staking incentives), Sky Stablecoins (USDS + DAI), and the Sky Agent Network (autonomous sub-DAOs that access USDS liquidity and pay fees back to Sky Protocol). The Agent Network has three role types: Sky Agents (operational allocators like Spark, Grove, Keel), Sky Agent Incubators (Sky Frontier Foundation, Obex), and Sky Ecosystem Contributors (Skybase manages sky.money, plus SFF supports research and development).

RWA Holdings
Sky Protocol holds over $2.5B in tokenized real-world assets, primarily US treasury bonds. This makes it the largest onchain holder of RWA among DeFi protocols, generating sustainable real-world yield that supports the stablecoin peg and protocol revenue.
Ecosystem Expansion
- Keel: Onchain capital allocator powering the $500M Solana Tokenization Regatta for cross-chain RWA
- Obex Incubator: Raised $37M with $2.5B Sky allocation to fund new ecosystem projects
- Sky Agents: Autonomous sub-DAOs handling specific ecosystem functions. 5 active as of Q1 2026 (Spark = Sky Lending front-end; Grove = traditional capital markets bridge; Keel = Solana capital allocator; Obex = institutional-grade incubator; Skybase = sky.money frontend). 5 more expected to launch in 2026 per SFF Q1 report; River poised to become the 6th Prime Agent in Q2.
- Multi-chain: USDS/DAI available across Ethereum, Arbitrum, Optimism, and expanding to Solana
Governance
Sky DAO (formerly MakerDAO)
Sky Protocol is governed by the Sky DAO through on-chain voting. SKY (and legacy MKR) token holders can vote on executive proposals, risk parameters, collateral types, and protocol upgrades. The governance framework is transitioning to the Endgame model with autonomous Sky Agents.
| Component | Role | Status |
|---|---|---|
| Sky DAO | Primary governance body for protocol decisions | Active |
| Executive Votes | Critical parameter changes and upgrades | Ongoing |
| Delegate System | Token holders delegate voting power to representatives | Active |
| Sky Agents | Autonomous sub-DAOs for specific ecosystem functions | 5 active (Spark, Grove, Keel, Obex, Skybase) + 5 more expected in 2026 |
Endgame Framework
The Endgame framework is Sky Protocol's long-term vision for decentralized governance. It introduces Sky Agents - autonomous sub-DAOs that handle specific ecosystem functions such as lending, RWA management, and ecosystem growth. Each Sky Agent operates with its own governance structure while remaining aligned with the broader Sky DAO.
Governance Risk: Justin Sun briefly became the largest MKR voter, highlighting the vulnerability of on-chain governance to large holder influence. The protocol has since implemented safeguards, but governance attack vectors remain a concern for any token-weighted voting system.
Risk Factors
Sky/Maker's Vault (CDP) system carries the same five mechanical risk channels as any onchain lending vault, stress-adjusted coverage, recovery endogeneity, liquidity stress, oracle integrity, and execution viability. See the Vault Credit Risk framework for the full decomposition; Maker's liquidation auction design is a worked example of the execution-viability channel under stress. Architecturally, Maker's CDP model sits outside the Monolithic / Modular / CeDeFi lending trio, users mint a stablecoin against collateral rather than borrow from a pool, so the counterparty risk mechanics differ from money-market protocols.
Governance & Decentralization Risk High Risk · Stage 0
Per defiscan.info's April 2026 review (source), Sky achieves an overall Stage 0 decentralization score, the lowest tier in their framework. Three categories drive the rating: Upgradeability (High), Autonomy (High), and Exit Window (High). The findings are real and sit on top of an otherwise mature protocol. Sky has been one of DeFi's most studied governance systems for years. The Stage 0 rating is not a statement that Sky is a poorly-run protocol; it's a statement that the governance architecture exposes critical permissions that are not protected by either a long Exit Window or a Security Council.
⚠ The 18-hour delay was cut from 30 hours via an emergency proposal
Sky's minimum delay between governance approval and execution is currently 18 hours. That value was recently reduced from 30 hours via an emergency proposal that bypassed the standard delay. Emergency proposals being used to weaken the protections that emergency proposals exist to bypass is the kind of meta-pattern an institutional allocator should track. The window during which a malicious proposal could be detected and countered is now under one trading day. Source: defiscan.info, 2026-04-27.
Specific findings (defiscan.info, 2026-04-27)
- Upgradeability (High): USDS and sUSDS are upgradeable contracts. Governance proposals can change the entire logic of those tokens. Critical Sky parameters (liquidations, debt ceilings, contract pauses) are also governance-changeable. A successfully passed malicious proposal could trigger forced liquidations, mint unbacked debt, or trap user funds.
- Autonomy (High). USDC dependency: USDS is effectively pegged to USDC, not USD. Users mint USDS from USDC at fixed 1:1 via the LitePSM. The debt ceiling is dynamic, it ramps $400M every 12 hours when current debt approaches the cap, up to a $10B maximum. At scale this makes USDS a wrapper on Circle's centralized stablecoin rather than a decentralized one.
- Autonomy (High). Chronicle oracle dependency: Sky uses Chronicle (rated Medium centralization in defiscan.info's separate Chronicle review) for collateral price feeds. Validator-set changes have a 7-day exit window. The Oracle Security Module (OSM) enforces a 1-hour delay on price updates and governance can freeze prices in an emergency, both real mitigants. Governance can change oracle providers via proposal but no automated fallback exists.
- Exit Window (High): 18-hour minimum delay (cut from 30h, see callout above). No Security Council. Governance is purely token-holder majority via the continuous-approval Hat model. Aligned Delegates hold majority voting power, concentrating influence among a curated group rather than the broad token-holder base.
- DSChief role-granting concern (auditor caveat): The DSChief governance contract has functions that grant fine-grained permissions to arbitrary addresses, and these functions emit no events. Historical misuse can only be verified by manually scanning all past governance proposals. The reviewer recommends those functions be blocked in future governance contract versions; for now, treat this as a monitoring point.
- Emergency Shutdown Module: 500,000 MKR sent irreversibly to the ESM contract triggers a permanent system shutdown. Funds sent to the ESM cannot be recovered even if no shutdown happens, by design, the cost of triggering shutdown is high. Under shutdown, supply/borrow halts and users can withdraw at the net asset value at the time of shutdown.
- Mitigant, withdrawal fee on staked SKY/MKR: Users withdrawing locked governance tokens face a 5% fee that increases up to 15% over time. This deters short-horizon governance attacks (a malicious actor who locks to vote can't exit cheaply afterward) but also locks in long-term voters, contributing to the Aligned Delegates concentration.
Path to higher decentralization stages
- Stage 1: Sky would need to (a) stop swapping USDS for USDC blind via the LitePSM (modify or replace that module) AND (b) increase the Exit Window to at least 7 days OR establish a Security Council.
- Stage 2: Exit Window of at least 30 days AND oracle provider at Stage 2 or equivalent decentralization (or Chronicle increases its own Exit Window to 30 days).
Source: defiscan.info Sky decentralization review (April 2026). TI's DeFi Risk Methodology incorporates these findings into the Governance, Admin Architecture, and Economic dimension scores for Sky. Sky's overall risk grade was recalibrated from B+ to B- following this review.
Migration Risk
Medium Risk- Only 56% of MKR holders have converted to SKY
- 1% penalty for late conversion increases quarterly
- Dual token system creates market fragmentation and confusion
- Some holders may resist migration indefinitely
Regulatory Risk
Medium Risk (mixed)- SEC staff guidance (April 2026): Non-custodial crypto interfaces can operate without broker-dealer registration. sky.money operates as a non-custodial frontend for USDS minting and Sky Savings Rate access, which fits within this safe harbor. However, the GENIUS Act's stablecoin reserve requirements and the prohibition on direct yield-sharing by stablecoin issuers remain the larger regulatory pressure on the USDS model
- The Binance DAI-to-USDS migration (April 2026) increases USDS's profile as a systemically important stablecoin, which may accelerate regulatory attention
- RWA holdings ($2.5B+ in treasury bonds, Obex Cohort 1 with $1B across 8 agents) subject to evolving securities regulations. Obex partners include regulated entities (Better, Securitize, Maple) which adds compliance infrastructure but also regulatory touchpoints
- Multi-jurisdiction exposure increases compliance complexity
Complexity Risk
Medium Risk- Dual token system (MKR/SKY, DAI/USDS) confuses new users
- Rebrand from MakerDAO to Sky Protocol still gaining recognition
- Endgame framework with multiple Sky Agents adds governance layers
- Multiple products (Spark, Horizon, Keel, Obex) dilute brand focus
Governance Concentration Risk Medium Risk
Distinct from the structural Stage-0 governance scope risk above, this section is about voter concentration, not permission scope.
- Historical governance attacks (Justin Sun as largest voter, 2020)
- Large holder influence in token-weighted voting; top 3 MKR holders controlled 78%+ of voting power per recent research
- Aligned Delegates hold majority voting power, concentrating influence among a curated group
- Sky Agent autonomy may create coordination challenges across the Endgame architecture
- 5-15% withdrawal fee on locked SKY/MKR deters short-horizon vote-and-exit but locks in long-term voters, reinforcing concentration
Administrative Architecture High Risk
MakerDAO (now Sky) pioneered spell-based governance, all protocol changes execute through smart contracts voted on by token holders rather than admin keys or multisigs. The architecture is sophisticated and has been battle-tested through multiple attacks (B.Protocol 2020, Justin Sun voting episodes). However, defiscan.info's April 2026 review concludes that the scope of permissions held by the on-chain governance is itself the risk: governance can upgrade USDS/sUSDS, mint stablecoin arbitrarily, force liquidations, change token logic, and freeze oracle prices. With an 18-hour delay and no Security Council, the window for detecting and countering a malicious proposal is narrow.
- No admin keys or multisig (positive): All protocol changes flow through "spell" contracts, code deployed for each executive vote. The winning spell becomes the "hat" via the DSChief contract. No individual holds privileged access.
- 18-hour GSM timelock (was 30h): The Governance Security Module enforces an 18-hour delay between a spell passing and execution. This was reduced from 30 hours via an emergency proposal (defiscan.info, 2026-04-27). Some non-delayed actions are also possible via Mom contracts (FlapperMom, FLopperMom, OSMMom, LitePSMMom) for emergency pauses.
- 1-hour Oracle Security Module: Price feed updates are delayed 1 hour via the OSM, providing detection time for oracle manipulation. MOM contracts can freeze oracles instantly if needed.
- Emergency Shutdown Module: 500,000 MKR threshold. Sending 500K MKR irreversibly to the ESM contract triggers permanent system shutdown. Tokens sent are unrecoverable even if no shutdown happens, the cost is intentionally high. Under shutdown, supply/borrow halts and users withdraw at net asset value at the shutdown moment.
- Protego (May 2025): Enables permissionless cancellation of any queued governance spell. Any user can create an Emergency Drop Spell to neutralize a malicious proposal waiting in the GSM queue. Real mitigant for the 18-hour-delay risk.
- Flash loan governance mitigated: After the October 2020 B.Protocol incident (13K MKR borrowed to pass a vote), GSM delay was increased and Oracle Freeze Module deauthorized. The 5-15% withdrawal fee on locked SKY/MKR also increases the cost of vote-and-exit attacks.
- Reviewer caveat. DSChief role granting: defiscan.info flags that DSChief contains functions which grant arbitrary addresses fine-grained permissions, and those functions emit no events. Historical misuse can only be verified by scanning all past governance proposals. Recommended remediation is blocking those functions in future governance contract versions.
Governance concentration caveat: Research shows the top 3 MKR holders controlled over 78% of voting power. Stani Kulechov (Aave founder) purchased $10M of MKR before a critical vote. The 1:24,000 MKR-to-SKY conversion ratio was partly designed to broaden distribution, but governance remains concentrated among large holders. Aligned Delegates currently hold majority voting power.

The 18-hour delay and 500K MKR ESM threshold above were corrected from previously-published 48h/50K MKR values that did not reflect post-Sky-rebrand parameters.
Competition Risk
Medium Risk- USDC and USDT dominate centralized stablecoin market
- Ethena USDe growing rapidly as decentralized stablecoin competitor
- Aave GHO competing in overcollateralized stablecoin space
- New RWA-backed stablecoins entering the market
Smart Contract Risk
Low Risk- Battle-tested since 2017. $12.46B Sky Lending TVL + $13.03B total Protocol Collateral end of Q1 2026, recovered well off the $19.8B 2021 peak following the Sky rebrand and Sky Agent Network buildout.
- Multiple audits from leading security firms
- Survived March 2020 "Black Thursday" market crash
- New modules (Sky Agents, Endgame) introduce new attack surfaces
