+- writeDepositETH and simulateDepositETH now take an `args.amount` instead of using a value arg.
+- getSecondsToNextL2Output throws an error if the passed latestL2BlockNumber is less than the latestBlockNumber reported by the l2OutputOracle.
+- writeFinalizeWithdrawalTransaction takes an `args` parameter like most other actions.

 `account`, `accessList`, `chain`, `dataSuffix`, `gasPrice`, `maxFeePerGas`, `maxPriorityFeePerGas`, and `nonce` can all also be passed and behave as with any viem writeContract call. See [their documentation](https://viem.sh/docs/contract/writeContract.html#writecontract) for more details.
