The DeFi protocol StaFi initiated a proposal in the community to launch a new Liquid Staking Derivatives (LSD) solution for the EVM compatible chain. rToken will be issued directly on the target chain to enhance its security and composability. In the new EVM LSD scheme, rToken Relay will be directly deployed to the target contract layer, enabling it to perform operations directly. The main feature of this scheme is that rToken will be issued directly on the target chain, and users do not need to perform cross-chain communication when obtaining rToken, and given the same token standard, rToken can be easily integrated into the target chain In DeFi. At the same time, in order to facilitate composability, the target chain should have various use cases for rTokens, including DEX, lending, options, etc. If there is no such use case on the target chain, it is recommended to issue rToken on StaFi Chain, because rDEX will be able to serve as a DEX for rToken trading on this platform. Therefore, the premise of this scheme is: the target chain should have a contract layer, and the pledge model is established in the contract layer. Without this premise, the development process would be costly and time-consuming. This solution can eliminate the user's need for multiple wallets and transactions, reduce Gas and security risks, and enable rTokens to interact with DeFi protocols on the target chain. Challenges include optimizing Gas consumption efficiency, upgrading solutions and rToken application updates. Risks include security module risks and contract layer risks.
