StaFi protocol is the first decentralized protocol to unlock the liquidity of Staked assets. StaFi aims to solve the contradiction between Mainnet security and token liquidity in PoS consensus. The token holders are staking through staking contracts built in StaFi protocol, and then get alternative tokens(rToken, such as rDOT, rATOM, rBNB, rSOL, etc.), rTokens are tradable and they can get staking rewards from an original chain at the same time.
StaFi is a combined abbreviation of Staking+Finance. It is a decentralized protocol built with the Substrate. The contract layer is composed of multiple staking contracts, and the application layer is mainly a trading platform of rTokens.
