{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "pfl_sendRawTransactionConditional",
    "params": [
        "0x123456789ABCDEF",
        {
            "knownAccounts": {...},
            "blockNumberMin": 1000000,

        },
    ]
}

Returns the hash of the transaction on success or an error object on failure. Note that receiving a transaction hash does not guarantee inclusion, as it might still fail due to:

  • Low gas price

  • Another 4337 transaction with a higher gas price containing the same userOp(s)

  • Validation failure after the "1 block penalty," even if it passed initially
