# Sky

> Get rewarded for saving, without giving up control.

Sky lets users earn rewards for saving digital assets while maintaining full control of their funds.

Sky is a decentralized protocol enabling users to manage funds and earn rewards through committed participation in governance. Users can trade tokens, participate in saving mechanisms, and receive token rewards for active participation.

## Products

- [Sky Money](https://thegrid.id/profiles/sky): Sky Money implements a cross-chain savings and rewards protocol where users maintain full control of deposited funds. The system enables direct stablecoin deposits into the Sky Savings Rate (SSR) module, yielding sUSDS tokens that accumulate value over time. It provides trading functionality between ecosystem tokens and supports operations across Ethereum, Solana, and Base blockchains. (Yield Aggregator, Live, Main Product)

## Assets

- [USDS (USDS)](https://thegrid.id/profiles/sky): USDS is a USD-pegged stablecoin in the Sky ecosystem, upgradeable from DAI or USDC at a 1:1 ratio. It is used for earning yield through the Sky Savings Rate, accumulating Sky Token Rewards, and as collateral across DeFi protocols on multiple blockchains. Unlike DAI, holders can deposit USDS into the Sky Savings Rate module to receive sUSDS tokens that automatically accumulate value over time, while simultaneously earning SKY governance token rewards through a dual-reward mechanism that operates without lockups or minimum deposits. (Stablecoin)
- [Savings USDS (sUSDS)](https://thegrid.id/profiles/sky): sUSDS is an ERC-4626 tokenized vault representing USDS deposits in the Sky Savings Rate module. It is used to earn yield on USDS while maintaining the ability to transfer, stake, and use the token across DeFi protocols on Ethereum and Base. Unlike USDS, which targets a stable $1 value, sUSDS appreciates over time as yield accrues, allowing holders to redeem it for more USDS than originally deposited. (Restaked Tokens)
- [SKY Governance Token (SKY)](https://thegrid.id/profiles/sky): SKY is the governance token of Sky Protocol, replacing MakerDAO's MKR token at a conversion rate of 1:24,000. It is used to vote on protocol decisions, stake for rewards, and borrow USDS stablecoin against staked positions. The protocol's Endgame strategy introduced SKY to enhance scalability and DeFi accessibility while allowing holders to convert back to MKR at any time. (Governance)
- [Maker (MKR)](https://thegrid.id/profiles/sky): MKR is the governance token of the Maker Protocol. It is used to vote on protocol parameters such as stability fees, collateral types, and other critical changes, with voting power proportional to the amount of MKR held. The token also serves as a recapitalization resource, allowing the system to mint and auction new MKR to cover shortfalls when the protocol becomes undercollateralized. (Governance)
- [Dai (DAI)](https://thegrid.id/profiles/sky): DAI is a USD-pegged stablecoin issued by the Sky Protocol, formerly known as MakerDAO. It is generated by users depositing collateral assets into Sky Protocol Vaults, providing access to liquidity while maintaining overcollateralization. DAI remains in circulation as a legacy token alongside USDS, with holders able to voluntarily upgrade to USDS at a 1:1 ratio. (Stablecoin)
- [Wrapped Ether (WETH)](https://thegrid.id/profiles/sky): WETH is a wrapped Ether token that conforms to the ERC-20 standard on Ethereum. It is used for trading on DEXs, collateral in lending markets, and liquidity provision where native ETH is not ERC-20 compatible. Anyone can mint WETH by depositing ETH 1:1 into the canonical WETH9 contract and redeem it at any time. (Wrapped Tokens)
