StaFi is the first DeFi protocol unlocking liquidity of staked assets. Users can stake PoS tokens through StaFi and receive rTokens in return, which are available for trading, while still earning staking rewards. rToken is a synthetic staking derivative issued by StaFi to users when users stake PoS tokens through StaFi rToken App . rTokens are anchored to the PoS tokens staked by users and the corresponding staking rewards. rTokens can be transferred and traded at any time.
