TrinityHook

EthereumRegistered

Charges a fixed 3% total fee on every swap (1.5% from each side) by minting ERC-6909 claims in beforeSwap and afterSwap. Fees are periodically settled to three immutable destinations: ~1% burns TRI tokens, ~1% sends ETH to a rewards contract, and ~1% adds liquidity via an engine contract. Only operates on native ETH / TRI pools.

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.

Runs at pool creation

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