Personal

Eth Personal allows you to interact with the Ethereum node’s accounts. For using Eth Personal package, first install Web3 package using: npm i web3 or yarn add web3 based on your package manager.


import { Web3 } from 'web3';
 const web3 = new Web3('http://127.0.0.1:7545');

 console.log(await web3.eth.personal.getAccounts());

For using individual package install web3-eth-personal packages using: npm i web3-eth-personal or yarn add web3-eth-personal.

import {Personal} from 'web3-eth-personal';

const personal = new Personal('http://127.0.0.1:7545');
console.log(await personal.getAccounts());

publicsendTransaction

  • sendTransaction(tx: Transaction, passphrase: string): Promise<string>

  • This method sends a transaction over the management API. NOTE: Sending your account password over an unsecured HTTP RPC connection is highly unsecure.

    @example
    const txHash = personal
    .sendTransaction({
         from: "0x0d4aa485ecbc499c70860feb7e5aaeaf5fd8172e",
        gasPrice: "20000000000",
        gas: "21000",
        to: "0x3535353535353535353535353535353535353535",
        value: "1000000",
        data: "",
        nonce: 0,
    },

    Parameters

    • tx: Transaction

      The transaction options

    • passphrase: string

      The passphrase of the current account

    Returns Promise<string>

    • The transaction hash

setConfig

  • Parameters

    Returns void

publicsign

  • sign(data: string, address: string, passphrase: string): Promise<string>

  • Calculates an Ethereum specific signature with: sign(keccak256("\x19Ethereum Signed Message:\n" + dataToSign.length + dataToSign))) Adding a prefix to the message makes the calculated signature recognisable as an Ethereum specific signature.

    If you have the original message and the signed message, you can discover the signing account address using web3.eth.personal.ecRecover NOTE: Sending your account password over an unsecured HTTP RPC connection is highly unsecure.

    @example
    const sig = await personal.sign("Hello world", "0x0D4Aa485ECbC499c70860fEb7e5AaeAf5fd8172E", "123456")
    console.log(sig)

    Parameters

    • data: string

      The data to sign.

    • address: string

      The address to sign with.

    • passphrase: string

      The passphrase to decrypt the account with.

    Returns Promise<string>

    • The signature.

publicsignTransaction

  • signTransaction(tx: Transaction, passphrase: string): Promise<string>

  • Signs a transaction. This account needs to be unlocked. NOTE: Sending your account password over an unsecured HTTP RPC connection is highly unsecure.

    @example
