eth_sendRawTransaction - Arbitrum

Example code for the eth_sendRawTransaction JSON RPC method. Сomplete guide on how to use eth_sendRawTransaction JSON RPC in GetBlock Web3 documentation.

This method broadcasts a signed raw transaction to the network for execution. The transaction must already be signed offline or by a wallet. Returns the transaction hash upon successful acceptance by the node.

Description

Data Type

result

The hash of the submitted transaction, as a hexadecimal string.

String

Use case

The eth_sendRawTransaction method helps developers to:

Submit fully signed transactions generated offline or by hardware wallets
Broadcast transactions without exposing private keys
Support automated transaction pipelines such as claim bots and arbitrage bots
Enable backend servers to send prebuilt transactions securely
Integrate custom signing flows for multi-chain smart contracts
Allow transaction submission even in environments without built in wallets

Error handling

max fee per gas less than block base fee

Invalid transaction
Insufficient funds

Integration with Web3

Using eth_sendRawTransaction with web3.js enables developers to:

Build backend services that prepare and sign transactions in a secure environment
Trigger automated onchain actions from server scripts
Support multisig configurations where the final signed output is broadcast via RPC
Allow dapps to submit transactions after signing via external wallets
Integrate custom key management systems or HSM based signing
