YieldHook

EthereumRegistered

A Uniswap v4 hook that implements a custom constant-product AMM for a YIELD token, deploying asset reserves into ERC4626 vaults (MetaMorpho) to earn yield. Fully overrides swap execution via beforeSwap with delta returns (FLOOD-style), supporting YIELD/wstETH, YIELD/USDC, and YIELD/USDT pools. YIELD token holders can claim pro-rata vault yield via MasterChef-style accumulators.

What it can do

Runs code on every swap

Its code executes inside each trade in pools that use it.

Can take tokens from swaps

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.

Can block LP withdrawals

It runs before liquidity is removed, so it can delay or refuse LP exits.

Gates who can add liquidity

It checks every deposit before it goes in.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.

Handles donations to LPs

It runs when someone donates tokens to the pool’s LPs.
