Maker / Sky (MKR/SKY)

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

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.

Key Catalysts

Maker/Sky operates a dual-token governance model following the rebrand. MKR is the legacy governance token, while SKY is the new governance token at a 1:24,000 conversion ratio. Late MKR converters face a 1% penalty that increases quarterly, incentivizing migration.

Token Overview

Revenue & Buybacks

Institutional Adoption: SDEV Digital Asset Treasury

A publicly traded Digital Asset Treasury (DAT) has emerged as a significant SKY holder. On-chain analysis (verified via Arkham Intel and Etherscan labels) reveals the following accumulation pattern as of March 2026:

Stablecoin Supply

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

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.

For additional details, see DefiLlama Token Rights

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.

Multi-Collateral System

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)

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).

Core Products & Services

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

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.

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 & 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.

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

• 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

• 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

• 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.

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

• 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

• 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
