Periphery

Peripheral contracts are those that are not necessary for CoW Protocol to function, but are used to enhance user experience.

Sending native tokens to the EthFlow contract in the wrong chain leads to irrecoverable loss of funds! Be very careful to choose the right address in the chains you’re currently using.

HooksTrampoline

Documentation: HooksTrampoline Upgradeable: No ❎ GitHub: HooksTrampoline.sol

Address: 0x60Bf78233f48eC42eE3F101b9a05eC7878728006

You should not assume that the HooksTrampoline contract address will remain fixed. Each solver may choose to use this implementation or another one, as long as it fulfills the hook intent.
