Overview
This has been proposed on ethereum/execution-apis
We need a new eth_fillTransaction RPC method that: (1) prepares a transaction by filling in missing fields (nonce, gas limit, fees, chain id, etc), and (2) simulates it with the same semantics as eth_call / eth_estimateGas, throwing with revert data if needed.
Currently, we use the following RPC methods to fill a transaction:
eth_getTransactionCount: for nonceeth_maxPriorityFeePerGas: for maxPriorityFeePerGaseth_getBlockByNumber: for maxFeePerGas (block.baseFee + maxPriorityFeePerGas)eth_estimateGas: for gaseth_chainId: for chainId
This is not ideal, because some of these calls depend on each other, which introduces increased latency. We should consolidate all these into the one "fill transaction" method.
