CowSwap

Swap

• Label: Swap_CowSwap
• Description: Swap a token to get another in exchange in CowSwap.
• Actions in execution process:
  1. Swap SELL_TOKEN to get BUY_TOKEN in exchange.

Note: When using the Pilot Extension and the Agile Execution App, all swaps will be routed through a delegate call to the OrderSigner (opens in a new tab) in order to facilitate parameter scoping and minimize risks.

Note: If SELL_TOKEN or BUY_TOKEN is a native token, it gets wrapped before executing the following functions.
