piSEI extraction of iSEI is credited immediately, then go to the DEX on the SEI chain to directly exchange iSEI for SEI and receive it in seconds. If you go through unbonding, you need to wait 21 days for it to complete.

This activity launched jointly by Sei and Binance can be done. First, transfer USDC across chains to the SEI chain, then deposit it into YeiFinance to complete the first task. After that, use the USDC collateral deposited in YEI to borrow SEI. The current APY is only 2.25%. Then, stake these SEI in the silo protocol to get iSEI, and stake iSEI in the PIT protocol to get piSEI. The current APY for this is 3.99% + a subsidy of 8.83%. A round of operations like this can earn interest differentials. Through this series of operations, it is equivalent to earning two sets of points (Deposit + Borrow) using USDC in YeiFinance without having to buy SEI spot, while also completing the SEI staking task, avoiding the risk of holding SEI during a downturn. If there are airdrops from YEI, SILO, and PIT later on, after $SEI , it is equivalent to storing some USDC not only to earn interest but also to bet on future airdrops from three protocols. Why not?
