Notes:

• In the payload, prioritySteps will contain the approval transaction calldata that needs to be executed before performing the transaction.

• The estimated gasLimit sent by our APIs are not based on any simulations because it is not possible to simulate gasLimit without having token allowance. The gasLimit sent by our APIs is a highly conservative estimate of the gas that a tx could use. Since the actual gas limit will be much lower, we suggest that the API users estimate the gasLimit themselves once the approval tx is mined.
