StaFi (short for Staking Finance) is a decentralized liquid staking protocol. Using StaFi contracts, token holders can make their staked assets liquid and tradeable. StaFi issues non-custodial rTokens such as rETH, rDOT, rKSM, rFIS, etc., which can be redeemed for underlying staked assets. These rTokens can be obtained by staking the underlying on the StaFi platform and trading on decentralized exchanges such as Uniswap. While rTokens are tradable and liquid, they also accrue in value based on the staking rewards of the underlying.
The StaFi blockchain is created with Substrate and is part of the Polkadot ecosystem. FIS is StaFi’s native cryptocurrency. It can be traded, used for gas fees, and staked to earn additional newly minted FIS.
