Developer notes

This page includes a running list of Across behaviors that developers who are using Across should be aware of:

ETH/WETH Behavior

Across liquidity pools are filled using WETH but, depending on the context, Across will sometimes send a user ETH and sometimes send a user WETH.

  • If a bridge transfer is being sent to an EOA, the EOA will receive ETH (not WETH)

  • If a bridge transfer is being sent to a contract, the contract will receive WETH (not ETH)

We look forward to helping you integrate with the best bridge around!
