Stafi (FIS) which is short for Staking Finance, is a decentralised finance (DeFi) protocol and the first of its kind to unlock liquidity of staked assets. Users are able to stake their proof of stake (PoS) tokens and receive an equal amount of rTokens (reward tokens) which are available for trading while still earning rewards for staking.
FIS is the native utility token of the Stafi protocol and is primarily used to secure the Stafi ecosystem through staking. FIS is also used for on-chain governance, paying transaction fees, and minting and redeeming rTokens.
