rBNB token is a synthetic staking derivative issued by StaFi for staking BNB through the StaFi rBNB App. rBNB tokens are anchored to the staked BNB assets and the corresponding staking rewards. rBNB tokens can be transferred and traded at any time. When a user deposits BNB into the rBNB contract, StaFi will calculate the amount of rBNB to issue to the user based on the current exchange rate between BNB and rBNB. When a user holds rBNB, StaFi will calculate the amount of redeemable BNB based on the real-time BNB staking reward.

StaFi protocol is the first decentralized protocol unlocking 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 it can get staking rewards from original chain at the same time.
