Description

Oracle-priced synthetic GBP stablecoin. beforeSwap returns full delta; V4 Quoter simulatable (fork test passes). Contracts immutable,
verified on Sourcify.

Hook means that any swap actually calls mint() or redeem(). The swap rate is a function of the USD/GBP rate and a curve that rewards minting/redeeming to balance sUSDS reserves.

Compiler run successful!

Note: because the hook fires mint() and redeem() the pool needs no actual tokens in the pool in order to execute - the point is that the swap-pool becomes the front-end for the permissionless mint() and redeem() functions so anyone can always execute the mint/redeem with no slippage at all, at any amount.
