eth_sendRawTransaction

post

/

Submits a raw transaction (serialized + signed) for broadcasting to the network. Transaction data should be encoded as a hexadecimal string starting with 0x.

Notes

• The node does not sign your transaction.
• You typically sign locally using an external library like ethers.js or web3.js.

EIP-4844 For blob transactions, the raw form must use the network format and include:

• blobs
• KZG commitments
• KZG proofs
