# Sending and simulating EIP-4844 Transactions
Currently there is no way for a application to request to send or simulate an [EIP-4844](https://eips.ethereum.org/EIPS/eip-4844) transaction. The only way to send a such transaction is to do do `eth_sendRawTransaction`:

{
    "method": "eth_sendRawTransaction",
    "params": [signedEIP4844txWithType]
}

where `signedEIP4844txWithType` is:

TransactionType || TransactionPayload

where TransactionPayload is:

rlp([tx_payload_body, blobs, commitments, proofs])

and `tx_payload_body` is:

[chain_id, nonce, max_priority_fee_per_gas, max_fee_per_gas, gas_limit, to, value, data, access_list, max_fee_per_blob_gas, blob_versioned_hashes, y_parity, r, s]

# Support for eth_sendTransaction
We should have a support for `eth_sendTransaction` method that takes in the blob body, commitments, blob_versioned_hashes and proofs:

{
    ...
    "method": "eth_sendTransaction",
    "params": [{
        "type": "0x3",
        "to": ...,
        "data": ...,
        "blobs": [
            {
                "payload": "0x...",
                "commitment": "0x...",
                "proof": "0x...",
                "blob_versioned_hash": "0x...",
            },
            {
                "payload": "0x...",
                "commitment": "0x...",
                "proof": "0x...",,
                "blob_versioned_hash": "0x...",
            }
        ]
    ...
    }
}

The fields `blob_versioned_hash`, `commitment` and `proof` can be made optional as they can be calculated from `payload`.

# Simulating EIP-4844 transactions
Another challenge we face is that there is no way to simulate exact EIP-4844 transactions. We feel these should also be included parameters that can be passed.

The methods `eth_call`, `eth_estimateGas` and `eth_multicallV1` should all support for both
1) Either passing just `blob_versioned_hashes`
3) Or passing `blob payloads`, `blob_versioned_hashes`, `commitments` and `proofs`.

The syntax for the transaction object should be the same that is used for `eth_sendTransaction`.
