Under protocol, set action as express-stake if you want the best path for the user. If the action is set as stake, our pathfinder will always generate a path that involves staking into StakeStone on Ethereum. In the case of express-stake, our pathfinder will also evaluate if directly swapping into STONE will result in a better output.

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.
