Stafi (short for Staking Finance) is the First DeFi Protocol Unlocking Liquidity of Staked Assets.<br /> Using Staking Contracts to liquid your staked assets and trade rToken (reward-Token) to hedge against exposures while still earning rewards.<br /> Stafi provides a secured solution to address the conflict between the mainnet security and the token liquidity in the Staking model. The token holder obtains bonds of equivalent value to the tokens by Staking in exchange for equivalent rTokens. For example, if a user stakes 1 XTZ, he will obtain rXTZ (reward XTZ) that is equivalent to the original token. rXTZ represents regular yields of tokens and the ownership of XTZ on the original chain. At the same time, rXTZ can be traded on the bond market that bases the Stafi protocol. Different to XTZ that is staked and locked on the original chain, tradable rXTZ has no lock period, but still keeps generating returns. As a result, holders of rXTZ no longer need to bear the risk of volatility and make timely judgments on market conditions. The Stafi protocol gives holders more rights. Due to financial motives, a holder will join the Stake contract for Staking for the risks no longer exist. This will serve as an adrenalin to Stake rate. Theoretically, projects that are decentralized enough will increase the Stake rate to over 90% (missing tokens not considered) while at the same time maintaining the liquidity over 90% with the help of Stafi protocol.<br /> Ⅱ.
