CoW Hooks

CoW Hooks allow users to pair any Ethereum action (or set of actions) with an order on CoW Protocol, leveraging the solvers to execute the actions together in the sequence.

Hooks come in two flavors, "pre-hooks" and "post-hooks".

Pre-Hooks​

These are actions that execute before the swap, allowing pre-hooks to be used to "set up" an order. Some examples including:

  • Unstaking tokens just-in-time for trading
  • Claiming an airdrop right before dumping
  • Signing token approvals so that the approval and the trade itself are batched together as a single action

Post-Hooks​

These are actions that execute after the swap, taking advantage of trade proceeds. Examples include:

  • Bridging funds to L2s
  • Staking funds
