Introduction to Sky
Sky is a decentralized finance ecosystem that developed from MakerDAO. It brings together stablecoin-related services, collateralized finance, staking-related functions, liquidity infrastructure, and on-chain governance.
Three related terms have different meanings. Sky Protocol is the broader system, SKY is its Ethereum-based governance token, and USDS is a stablecoin designed to track the value of the US dollar.
What Is Sky?
Sky is a collection of decentralized finance tools and smart contracts. Smart contracts are programs deployed on a blockchain that perform defined actions when their conditions are met.
The ecosystem uses different assets for different purposes. SKY allows holders to participate in governance directly or delegate their voting power, while USDS is intended to provide a more stable unit of value within the ecosystem.
SKY is an ERC-20 token on Ethereum. It is not the native coin used to pay Ethereum transaction fees; interacting with SKY or Sky smart contracts on Ethereum requires network gas fees that are separate from SKY’s governance function.
From MakerDAO to Sky
Sky developed from MakerDAO, an Ethereum-based decentralized finance ecosystem associated with collateralized finance and the DAI stablecoin. MKR historically served as the MakerDAO governance token.
MakerDAO rebranded as Sky in 2024 as part of a wider change to the ecosystem. SKY was introduced as the governance token for Sky Protocol, while USDS was introduced as a stablecoin within the newer structure.
The transition does not mean that every earlier Maker asset or smart contract simply disappeared. DAI, MKR, SKY, and USDS have distinct roles, and users need to check the applicable functions and transition conditions for each asset.
How Does Sky Work?
Sky uses blockchain-based smart contracts to provide decentralized finance functions. Its documented components cover stablecoins, vaults, collateral-related services, staking, liquidity, governance, rates, bridges, security, and shutdown procedures.
Collateralized finance generally involves locking an accepted asset in a smart contract under defined conditions. Depending on the specific Sky function and its current rules, a user may be able to borrow USDS against an eligible position. If the position no longer meets its collateral requirements, it may face liquidation.
SKY holders can participate in on-chain governance by voting on proposals or delegating their voting power to another participant. Governance may change protocol parameters, risk settings, reward structures, and other operating conditions, so Sky should not be viewed as a permanently fixed system.
Sky also provides staking-related functions. Staked SKY may retain governance utility and may be eligible for rewards under supported conditions, but those conditions can change and do not represent guaranteed returns.
Key Features of Sky
- SKY governance: SKY is used to participate in Sky Protocol governance through direct voting or delegation.
- USDS stablecoin: USDS is designed to track the value of the US dollar and has a different purpose from the SKY governance token.
- Staking-related functions: Sky documentation covers staking facilities through which eligible participants may use SKY under the protocol’s current conditions.
- Collateral and lending: The ecosystem includes collateralized finance and borrowing-related functions, with requirements that may be changed through governance.
- Vaults and liquidity: Official developer documentation covers vaults and liquidity infrastructure as parts of the wider protocol.
- Bridge infrastructure: Sky documentation includes the USDS Ethereum–Solana Bridge and the Base ETH Native Bridge, which support specific cross-network workflows.
- Separate gas fees: SKY’s governance role is distinct from the Ethereum network fees required for transactions and smart-contract interactions.
MKR, SKY, USDS, and DAI Explained
| Asset | General role |
|---|---|
| MKR | The former governance token associated with MakerDAO. |
| SKY | The Ethereum-based governance token used for Sky Protocol governance. |
| USDS | A Sky ecosystem stablecoin designed to track the value of the US dollar. |
| DAI | The stablecoin historically associated with the Maker ecosystem. |
MKR and SKY are separate tokens. Verified source material states that SKY has assumed the governance role and that MKR is no longer used for Sky governance voting.
A supported process exists for converting MKR to SKY. However, the effective terms may be affected by a delayed-upgrade penalty, and governance can adjust relevant conditions. Anyone considering a conversion should check the current official interface and governance materials rather than relying on an older conversion figure.
USDS and DAI should also be distinguished from the governance tokens. They are stablecoin assets, while MKR and SKY relate to governance in their respective ecosystem structures.
Advantages, Limitations, and Risks
Sky’s main practical strength is that it combines governance, stablecoin-related functions, collateralized finance, staking, vaults, liquidity tools, and documented bridge infrastructure within one broader ecosystem. Governance also gives SKY holders a way to vote directly or assign their voting power to delegates.
Governance participation does not eliminate risk. Decisions made through governance can change protocol settings, collateral conditions, reward structures, and other rules, creating uncertainty for users who rely on earlier terms.
- Smart-contract risk: Code vulnerabilities or unexpected smart-contract behavior could cause loss or prevent functions from operating as expected.
- Collateral and liquidation risk: A collateralized position may be liquidated if it no longer satisfies the required conditions.
- Stablecoin risk: A stablecoin is designed to track a reference value, but that design does not guarantee an identical market price at all times.
- Governance risk: Voting outcomes can alter protocol parameters, policies, and user conditions.
- Token volatility: SKY’s market price can fluctuate, including while the token is being used in staking-related functions.
- Conversion risk: MKR-to-SKY terms and any delayed-upgrade penalty must be checked at the time of conversion.
- Bridge and network risk: Cross-network activity introduces dependencies on the relevant bridge, networks, fees, and transaction processes.
- Wallet security risk: Protocol security is separate from the security of a user’s wallet, private keys, and recovery phrase.
Practical Considerations When Using Sky
Users may encounter Sky when researching MakerDAO’s development, interacting with USDS, examining governance proposals, using staking-related functions, or exploring collateral and liquidity tools.
Before connecting a wallet, verify that the website or application is an authentic interface. Impersonation sites can imitate the appearance of a legitimate service.
Confirm the correct token contract address rather than relying only on a token name or symbol. Different assets can use similar labels, and selecting the wrong contract can lead to an unintended transaction.
For an MKR-to-SKY conversion, check the current conversion terms and any delayed-upgrade penalty in up-to-date official materials. For staking, confirm the available functions, reward conditions, and withdrawal rules before interacting.
For collateralized positions, review the applicable collateral requirements and liquidation conditions. Network fees should also be checked because they are separate from the role or value of SKY.
Never provide a private key or recovery phrase to a website, application, or another person. These credentials can provide control over the associated wallet and assets.
Frequently Asked Questions
Is Sky the successor to MakerDAO?
Sky is the ecosystem that developed from MakerDAO following its 2024 rebranding and structural transition.
How does SKY differ from MKR?
MKR was the former MakerDAO governance token, while SKY is the token used for current Sky Protocol governance.
How does SKY differ from USDS?
SKY is a governance token. USDS is a stablecoin designed to track the value of the US dollar, so the two assets serve different purposes.
Does MKR still have a Sky governance role?
Verified source material states that MKR is no longer used for Sky governance voting and that SKY holds the governance role.
Are SKY staking rewards guaranteed?
No. Reward conditions can change, and the market value of SKY can fluctuate. Staking should not be treated as a guaranteed-return product.
Why should current conditions be checked in official documentation?
Governance can change protocol parameters, conversion conditions, collateral requirements, and staking arrangements. Older information may therefore no longer describe the conditions that apply to a current transaction.

Key Takeaway
Sky is the decentralized finance ecosystem that developed from MakerDAO. SKY now serves as its governance token, while USDS has a separate role as a stablecoin designed to track the value of the US dollar.
Understanding Sky requires distinguishing the protocol from its tokens and recognizing that governance can change operating conditions. Smart-contract, collateral, liquidation, stablecoin, token-price, bridge, network, conversion, and wallet-security risks remain important considerations.
