Why mint SherX instead of paying stakers directly in protocol payment tokens? It really comes down to gas. If Sherlock has 20 protocols on board and 20 different tokens being paid into the pool, it’s very costly on unstake to pay stakers in 20 different tokens. On top of that, the staker might have staked ETH and they just want more ETH. So they have to do 20 separate transactions after the first 20 transactions to get all the tokens into ETH. Whereas if SherX is minted to represent a proportional share of the 20 tokens, it’s more gas efficient and it will be easier for the staker to get from SherX to ETH or a specific token they want to hold. In order to make this possible, a Uniswap pool for SherX (SherX vs. ETH) will be created. In addition, anyone can redeem SherX tokens for the underlying collateral (the 20 different tokens, in this example) at any time using the redeem function. This will insure that SherX always trades fairly close to the value of its underlying collateral (because an arbitrager could buy discounted SherX tokens on Uniswap and redeem them for the full value of the underlying collateral).
