Web3Eth

The Web3Eth allows you to interact with an Ethereum blockchain.

For using Web3 Eth functions, first install Web3 package using npm i web3 or yarn add web3 based on your package manager usage. After that, Web3 Eth functions will be available as mentioned in following snippet.

import { Web3 } from 'web3';
const web3 = new Web3('https://mainnet.infura.io/v3/<YOURPROJID>');

const block = await web3.eth.getBlock(0);

For using individual package install web3-eth package using npm i web3-eth or yarn add web3-eth and only import required functions. This is more efficient approach for building lightweight applications.

import { Web3Eth } from 'web3-eth';

const eth = new Web3Eth('https://mainnet.infura.io/v3/<YOURPROJID>');
const block = await eth.getBlock(0);

Methods

calculateFeeData

This can be a bigint for precise calculation or a number to support decimals. The default value is 2 (BigInt). If a number is provided, it will be converted to bigint with three decimal precision.
alternativeMaxPriorityFeePerGasbigintethUnitMap.Gwei(optional) The alternative maxPriorityFeePerGas to use when calculating maxFeePerGas, if the node supports EIP-1559 but does not support the method eth_maxPriorityFeePerGas. The default value is 1 gwei.

getWork

getWork(): Promise<[string, string, string]>

Gets work for miners to mine on. Returns the hash of the current block, the seedHash, and the boundary condition to be met ('target').

Returns

Promise<[string, string, string]>

The mining work as an array of strings with the following structure:

String 32 Bytes - at index 0: current block header pow-hash String 32 Bytes - at index 1: the seed hash used for the DAG. String 32 Bytes - at index 2: the boundary condition ('target'), 2^256 / difficulty.

requestAccounts

requestAccounts(): Promise<string[]>

This method will request/enable the accounts from the current environment and for supporting EIP 1102 This method will only work if you’re using the injected provider from a application like Metamask, Status or TrustWallet. It doesn’t work if you’re connected to a node with a default Web3.js provider (WebsocketProvider, HttpProvider and IpcProvider). For more information about the behavior of this method please read EIP-1102: Opt-in account exposure.

Returns

Promise<string[]>

An array of enabled accounts.

subscribe

subscribe<T, ReturnType>(name, args?, returnFormat?): Promise<InstanceType<RegisteredSubscription[T]>>

Lets you subscribe to specific events in the blockchain.

Type parameters

NameType
Textends keyof RegisteredSubscription
ReturnTypeextends DataFormat = DataFormat

Parameters

NameTypeDescription
nameTThe subscription you want to subscribe to.
args?ConstructorParameters<RegisteredSubscription[T]>[0]Optional additional parameters, depending on the subscription type.
returnFormatReturnType-

Returns

Promise<InstanceType<RegisteredSubscription[T]>>

A subscription object of type RegisteredSubscription. The object contains:

  • subscription.id: The subscription id, used to identify and unsubscribing the subscription.
  • subscription.subscribe(): Can be used to re-subscribe with the same parameters.
  • subscription.unsubscribe(): Unsubscribes the subscription and returns TRUE in the callback if successful.
  • subscription.args: The subscription arguments, used when re-subscribing.

You can use the subscription object to listen on:

  • on("data") - Fires on each incoming log with the log object as argument.
  • on("changed") - Fires on each log which was removed from the blockchain. The log will have the additional property "removed: true".
  • on("error") - Fires when an error in the subscription occurs.
  • on("connected") - Fires once after the subscription successfully connected. Returns the subscription id.

Example

// Subscribe to `logs`
const logSubscription = web3.eth.subscribe('logs', {
address: '0x1234567890123456789012345678901234567890',
topics: ['0x033456732123ffff2342342dd12342434324234234fd234fd23fd4f23d4234']
});
logSubscription.on('data', (data: any) => console.log(data));
logSubscription.on('error', (error: any) => console.log(error));

Example

// Subscribe to `newBlockHeaders`
const newBlocksSubscription = await web3.eth.subscribe('newBlockHeaders');

newBlocksSubscription.on('data', async blockhead => {
console.log('New block header: ', blockhead);

// You do not need the next line, if you like to keep notified for every new block
await newBlocksSubscription.unsubscribe();
console.log('Unsubscribed from new block headers.');
});
newBlocksSubscription.on('error', error =>
console.log('Error when subscribing to New block header: ', error),
);

subscribe('pendingTransactions')

Subscribes to incoming pending transactions. You can subscribe to pending transactions by calling web3.eth.subscribe('pendingTransactions').

(await web3.eth.subscribe('pendingTransactions')).on('data', console.log);

subscribe('newHeads')

( same as subscribe('newBlockHeaders')) Subscribes to incoming block headers. This can be used as timer to check for changes on the blockchain.

The structure of a returned block header is BlockHeaderOutput:

(await web3.eth.subscribe('newHeads')).on( // 'newBlockHeaders' would work as well
'data',
console.log
);

subscribe('syncing')

Subscribe to syncing events. This will return true when the node is syncing and when it’s finished syncing will return false, for the changed event.
