What is Sky? Sky is a decentralized finance protocol on Ethereum that evolved from MakerDAO, combining stablecoin issuance, collateralized lending, savings products, and on-chain governance. Its main tokens are SKY, the governance and incentive asset, USDS, the protocol’s primary stablecoin, and sUSDS, which represents a position in the Sky Savings Rate.
Core technology and architecture
Sky uses Ethereum smart contracts rather than operating its own blockchain. Users can deposit approved collateral into vaults and generate dollar-denominated stablecoin liquidity. The protocol uses governance-set collateral requirements, fees, risk limits, liquidations, and oracle data to manage the system.
USDS is the upgraded successor to DAI, and Sky supports a 1:1 conversion between the two. Users can convert USDS into sUSDS through an ERC-4626-compatible savings vault, with the value of the position changing according to the governance-set Sky Savings Rate. SKY is an Ethereum token used for voting, delegation, staking, and ecosystem incentives. Its Ethereum contract is 0x56072c95faa701256059aa122697b133aded9279.
Primary uses and applications
Sky’s core use case is decentralized borrowing. Collateral can be locked in smart contracts to create stablecoin liquidity without selling the underlying assets. USDS and DAI can also be used for payments, trading, settlement, decentralized-exchange liquidity, and lending applications.
The protocol connects stablecoin issuance with savings and governance. SKY holders can vote on collateral types, risk parameters, savings rates, ecosystem funding, and protocol upgrades. The Staking Engine can provide voting power, governance-approved rewards, and collateral utility for USDS borrowing.
Sky is also expanding into tokenized real-world assets and institutional credit. Its modular “Stars” structure includes Spark for lending, Grove for institutional-grade credit, Keel for capital allocation on Solana, and Obex for ecosystem incubation.
Who is behind Sky and where is it based?
Sky is the rebranded successor to MakerDAO. Rune Christensen is the founder and principal public figure associated with the project. MakerDAO’s origins date to 2014, while the first formal DAI system launched on Ethereum in 2017.
The Maker Foundation supported the protocol’s early development before transferring operational responsibility to MakerDAO governance and beginning its dissolution in 2021. In August 2024, MakerDAO rebranded as Sky and introduced SKY and USDS while retaining compatibility with the legacy Maker and DAI systems.
Sky does not have one publicly confirmed corporate headquarters or a single company operating the entire protocol. Its development and governance involve distributed contributors, delegates, facilitators, foundations, and ecosystem operators. The Dai Foundation is an independent Danish nonprofit responsible for intellectual-property stewardship, and its terms state that it is governed by Danish law. The sources do not confirm that the Dai Foundation owns or operates the entire Sky protocol. Historical Maker Foundation structures also included a Cayman Islands foundation company, but this does not establish the current legal jurisdiction of Sky as a whole.
Tokenomics and supply
The documented conversion rate is 1 MKR to 24,000 SKY. CoinStats reports a circulating supply of 23,424,581,289 SKY and a total supply of 23,459,804,204 SKY. The difference indicates that most of the reported supply is already circulating, although a complete allocation breakdown was not provided.
SKY does not have a permanently fixed inflation or deflation rate. Governance can approve rewards and emissions, while the Smart Burn Engine can use protocol surplus for buybacks, staking rewards, and burns. Current capital-management documentation describes a 45% allocation to SKY buybacks distributed as staking rewards, 45% to USDS staking rewards, and 10% to buyback and burn. These parameters remain subject to governance changes.
CoinStats lists SKY at $0.07837, with a 24h change of -4.35%, a market cap of $1.84B (rank #69), and 24h volume of $19.32M. The all-time high is $0.1005, and the current price is 22.05% below it.
Consensus and security
Sky has no independent consensus mechanism. Its contracts inherit Ethereum’s proof-of-stake settlement and validator security. Additional protocol security depends on collateralization, liquidations, governance controls, smart-contract audits, emergency procedures, and oracle systems.
Chronicle provides collateral price data, while Sky’s Oracle Security Module can delay price updates by one hour and freeze a current price during an emergency. These safeguards reduce response time for governance and security participants but do not remove smart-contract, oracle, market, or governance risks.
Competitive position and roadmap
Sky’s main advantages are MakerDAO’s established stablecoin infrastructure, Ethereum composability, decentralized governance, and an integrated connection between borrowing, savings, staking, and treasury management. The Stars model also allows specialized lending, institutional-credit, and cross-chain initiatives to operate within a broader governance and liquidity framework.
Current development focuses on USDS adoption, sUSDS and staking, MKR-to-SKY migration, Smart Burn Engine operations, Spark and Grove expansion, tokenized real-world assets, and Ethereum-to-Solana connectivity. Governance remains active on collateral onboarding, risk parameters, allocator permissions, rewards, and ecosystem-agent mandates.
