<Warning>
  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`](/cow-protocol/reference/contracts/periphery/hooks-trampoline) **Upgradeable**: No ❎ **GitHub**: [HooksTrampoline.sol](https://github.com/cowprotocol/hooks-trampoline/blob/main/src/HooksTrampoline.sol)

**Address**: `0x60Bf78233f48eC42eE3F101b9a05eC7878728006`

<Warning>
  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.
