EulerSwap

EthereumRegistered

EulerSwap is a custom-curve Uniswap v4 hook backed by Euler Protocol lending vaults. Swaps are fully handled in beforeSwap via a BeforeSwapDelta: input tokens are deposited into an Euler vault and output tokens withdrawn from another, with a custom curve invariant enforced on each trade.

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.

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.
