What is Sky crypto? Sky is the Ethereum-based decentralized finance protocol formerly known as MakerDAO, which rebranded on 27 August 2024 as part of its Endgame overhaul. Its core products are a stablecoin, USDS, and a savings and lending system, with SKY serving as the governance and incentive token.
Core technology and blockchain architecture
Sky is not a standalone blockchain. It consists of open-source, self-executing smart contracts deployed on Ethereum mainnet, so it runs no consensus layer or validator set of its own and inherits Ethereum's security. The rebrand changed the protocol's token names: DAI became USDS, MKR became SKY at 24,000 SKY per MKR, and the DAI Savings Rate became the Sky Savings Rate.
The savings token sUSDS is ERC-4626 compliant, and Sky's documentation states that it is live on Ethereum, Base, and Solana.
Primary use cases
- Stablecoin issuance: USDS is backed by overcollateralised loans and stablecoin reserves. Its supply was about $10.04B at the end of Q2 2026, after peaking above $11.8B in early April.
- Savings: Depositors can hold sUSDS, which accrues the Sky Savings Rate without lockups. The rate is set by SKY governance, and Sky.money states that it does not control, set, or guarantee the rate.
- Capital allocation: Semi-independent Sky Agents, including Spark, Grove, and Keel, borrow USDS and deploy it into yield strategies.
- Exchange migration: Coinbase completed its DAI-to-USDS migration in April 2026.
Who is behind Sky and where is it based?
The team is not anonymous. Rune Christensen is the publicly named co-founder and founder of MakerDAO, and Sky Frontier Foundation (SFF) lists him as Director and Co-founder. SFF also names David García Ríos as Director, Legal.
Sources differ on the founding year. Bloomberg reports that Christensen launched MakerDAO in 2014, while Messari says the idea of Maker was first introduced on 26 March 2015. Maker launched Single-Collateral DAI in 2017 and Multi-Collateral DAI in 2019. The original Maker Foundation was dissolved in 2021, with control passing to community-run Core Units.
The legal entity most clearly documented is Sky Frontier Foundation. The GLEIF record lists it as a Cayman Islands foundation company with status ACTIVE, and its legal address is in George Town, Cayman Islands. SFF's terms state that it does not control the Sky Protocol or SkyDAO governance. Sources do not establish a single headquarters for the whole protocol.
Tokenomics
At the time of the market snapshot, SKY traded at $0.06837 with a 24h change of +2.38%. It ranks #71 by market cap at $1.60B, with 24h volume of $6.56M. The price is 32.22% below its all-time high of $0.1009.
Circulating supply is 23,421,320,574 SKY, and total supply is 23,452,431,916 SKY. In November 2024, governance capped total supply at 23,462,665,147 SKY, with no programmatic emissions and no future minting. The sources reviewed do not include a full distribution breakdown or vesting schedule.
Supply is reduced through buybacks and burns rather than issuance. Each settlement cycle under Stage 2 of staking rewards, ratified on 13 August 2026, allocates 22.5% of surplus to SKY buybacks for staking rewards, 22.5% to USDS staking rewards, 5% to SKY buy-and-burn, and up to 50% to the surplus buffer. The buyback dashboard shows a cumulative total of 2,047,114,880 SKY bought on 28 October 2026. On 14 September 2026, Sky announced that 2.86M SKY had been permanently removed from circulation.
Consensus mechanism and network security model
Security is inherited from Ethereum's proof-of-stake consensus, with additional protocol-level risk controls. ChainSecurity audited the Direct Deposit V2 contracts on 20 March 2024 and the Arbitrum Token Bridge on 9 October 2024, and assessed the Sky OApp OFT contracts on 17 October 2025. Cantina's September 2025 review of the LayerZero governance contracts reported no critical, high, or medium findings.
SparkLend uses a three-oracle median from RedStone, Chainlink, and Chronicle. Moody's assigned Sky Protocol a B3 counterparty risk rating with a stable outlook on 6 October 2026. S&P Global assigned a B- rating with a stable outlook in August 2025, and its report states that Christensen controls 9% of governance tokens, and that low voter turnout means he effectively influences key governance decisions.
Key partnerships and ecosystem integrations
- Galaxy Digital: On 23 September 2026, Galaxy added $100M of sUSDS to its corporate treasury and approved it as institutional loan collateral.
- Prime Agent Vaults: These held $6.84B at the end of Q2 2026, with about $2.58B deployed across Janus Henderson, BlackRock, Anchorage, PayPal, Securitize, and Galaxy.
- BlackRock BUIDL: Spark has roughly $500M allocated to the BUIDL fund.
- Wallet integrations: Privy, a Stripe-owned wallet provider, integrated sUSDS into its developer tools.
Competitive position and development activity
Sky reports gross protocol revenue of $107.35M in Q2 2026, up 10.5% year over year, and net protocol surplus of $33.29M, its fifth consecutive positive quarter. Sky describes itself as the largest onchain capital allocator, a self-reported claim. Moody's described Sky as the first stablecoin protocol it has rated.
Sky is moving governance toward Sky Agents, and Spark and Grove were still governed at the Core DAO level as of 31 July 2025. A 1.25x savings bonus, paid in USDS, was announced to start on 7 October 2026. That announcement came from the Skye Community X account rather than a governance document.
