LSD&PERP CCTP Yeild Protocol

Track

CCTP

Product Introduction

现在有很多条pos链，它们都有自己的lsd协议，用户可以质押原生代币获取收益，但是需要承受价格下跌的风险，所以需要做空等量代币，但是这条链不一定有适合的perp交易所做对冲，比如以太坊慢且贵，某些链的perp协议流动性不充足。所以可以通过cctp将两者关联起来，在流动性充足的其他链的协议上比如gmx或dydx上做空代币，在lsd协议上stake等量的代币，这样来使风险敞口中性，同时可以获得stake的收益还有做空的资金费率收益。 本次示例使用goerli的steth和goerli arb的gmx做示例。 cctp
