EulerSwap
UnichainRegisteredA custom-curve AMM hook backed by Euler lending vaults. In beforeSwap, the hook takes full control of swap execution: it computes quotes against a configurable bonding curve, deposits input tokens into the counterparty's Euler vault, and withdraws output tokens from the other vault, returning a BeforeSwapDelta to settle accounting with the pool manager. Standard Uniswap concentrated liquidity positions are explicitly blocked.
What it can do
Its code executes inside each trade in pools that use it.
It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.
It checks every deposit before it goes in.
It runs when a pool is created, often to lock in that pool’s settings.
It runs when someone donates tokens to the pool’s LPs.
