eth_sendTransaction - Arbitrum

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

This method sends a new transaction to the network. Unlike eth_sendRawTransaction, this method requires the node or connected wallet to manage the private key and sign the transaction on behalf of the user. Used mostly in browser wallets or trusted local nodes.

Parameters

Field	Type	Description
from	string	Address sending the transaction. Must be unlocked on the node or wallet.
to	string or null	Address receiving the transaction. Null if deploying a contract.
gas	string	Gas limit for execution. Optional.
gasPrice	string	Gas price for the transaction. Optional.
maxPriorityFeePerGas	string	EIP-1559 priority fee. Optional.
maxFeePerGas	string	EIP-1559 max total fee. Optional.
value	string	Amount of ETH to transfer, in wei.
data	string	Hex encoded data payload for contract interaction. Optional.
nonce	string	Nonce for the transaction. If omitted, the node assigns automatically.

Reponse Parameter Definition

Field	Description	Data Type
result	The hash of the submitted transaction, as a hexadecimal string.	String

Use case

The eth_sendTransaction method helps developers to:

• Initiate transactions directly from wallets without manual signing

• Deploy contracts when using browser wallets like MetaMask

• Allow frontends to request transactions from users without exposing private keys

• Create a trustless UI where signing occurs locally on the user's device

• Simplify interactions for beginners by handling nonce, gas, and signing automatically

• Build dApps that request on-chain operations with minimal backend logic

Error handling

Status Code	Error Message	Cause
403	Forbidden	Missing or invalid ACCESS_TOKEN.
-3200	Unknown account	Invalid wallet address Insufficient funds gas too low gas price too low nonce too low invalid sender

Integration with Web3

The eth_sendTransaction method enables developers to:

• Trigger wallet popups for signing transactions in dApps

• Build trustless browser interfaces where key management stays entirely client side

• Avoid handling private keys on servers

• Create user friendly transaction flows for DeFi, NFTs, gaming, and marketplaces

• Use MetaMask or WalletConnect to sign and broadcast actions securely
