Skip validation of the EIP7702 Authority signature when EstimateGas

[peekpi]

Rationale

When EstimateGas is called, if the authorizationList field is provided, its signature is verified during execution. If the signature is invalid, the sender's code is not updated. Example request on sepolia:

{
    "jsonrpc": "2.0",
    "method": "eth_estimateGas",
    "params": [
        {
            "from": "0x0338f81BEDcE242929Fad9b6e7379B0295211577",
            "to": "0x0338f81BEDcE242929Fad9b6e7379B0295211577",
            "value": "0x0",
            "data": "0x61461954",
            "authorizationList": [
                {
                    "chainId": "0xaa36a7",
                    "nonce": "0x1",
                    "address": "0x6587f125a2626d59c2600ae058ffb62c8651ed33",
                    "yParity": "0x0",
                    "r": "0x0",
                    "s": "0x0"
                }
            ]
        }
    ],
    "id": 71
}

The alternative is to override the sender's code with a third argument, which works, but feels a little weird. The third parameter is import by #30695 .

{
    "jsonrpc": "2.0",
    "method": "eth_estimateGas",
    "params": [
        {
            "from": "0x0338f81BEDcE242929Fad9b6e7379B0295211577",
            "to": "0x0338f81BEDcE242929Fad9b6e7379B0295211577",
            "value": "0x0",
            "data": "0x61461954",
            "authorizationList": [
                {
                    "chainId": "0xaa36a7",
                    "nonce": "0x1",
                    "address": "0x6587f125a2626d59c2600ae058ffb62c8651ed33",
                    "yParity": "0x0",
                    "r": "0x0",
                    "s": "0x0"
                }
            ]
        },
        "latest",
        {
                "0x0338f81BEDcE242929Fad9b6e7379B0295211577":{
                    "code": "0xef0100e22f5f1a03db3af7bdc7b40c146524ad19a7e513"
                }
        }
    ],
    "id": 71
}

Implementation

Skip authorityList validation when calling EstiamteGas.

Not sure if it's the same issue. I’m using Wallet.authorize() from ethers v6.13.6 (supports EIP-7702) on Sepolia.

When ethers calling estimateGas on Geth/v1.15.5-stable-4263936a/linux-amd64/go1.23.7 (from RPC URL: https://ethereum-sepolia-rpc.publicnode.com), errors like

Error: missing revert data (action="estimateGas", data=null, reason=null, transaction={ "data": "0x", "from": "0xe7C0B0c95a2551d9C815ecc9555539489F667276", "to": "0x0000000000000000000000000000000000000000" }, invocation=null, revert=null, code=CALL_EXCEPTION, version=6.13.6)

often occur, though sometimes it succeeds and the transaction is broadcast.

@peekpi Can you explain the rationale for this?

[jwasinger]

Ah, I think I get it: from wallet's POV the user shouldn't have to be prompted to sign anything before being presented with the cost of the tx (?)

would like to work on this!
