Hi!

Features

Alongside some small bug fixes, this release contains two large improvements, authored by @nivida.

  • The Websocket Provider module has been rewritten and now supports an auto-reconnect option which should dramatically improve the stability of connections to remote clients like Infura. You can enable auto-reconnect by configuring the provider as below.

    const Web3 = require('web3');

const options = {
  // Enable auto reconnection
  reconnect: {
      auto: true,
      delay: 5000, // ms
      maxAttempts: 5,
      onTimeout: false
  }
};

const ws = new Web3.providers.WebsocketProvider('ws://localhost:8546', options)

    More info about configuration can be found in the docs here. (PR #3190).

  • The ENS module now allows connection to a custom registry. We've also added support for a large number of additional Registry and Resolver methods. The complete ENS API at Web3 is available in the docs here. (PR #3325).

Note about behavioral change in Geth 1.9.12

Recently in issue #3456 @Aniket-Engg drew attention to an important breaking change in Geth 1.9.12 which affects Web3 users. From their release notes:

eth_call will not default to your first account any more if you don't explicitly specify a sender. This was done to avoid the same input behaving differently in different environments.

This means that if you're:

  • calling view methods that refer to a msg.sender
  • calling estimateGas
  • calling methods with .call

... without explicitly setting a from address in your request options, you may see errors or unexpected behavior.

In Web3.js, the from address can be specified on a per-call basis or by setting the defaultAccount property

// Call
myContract.methods.myMethod(123).call({from: '0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe'});

// Contract
web3.eth.Contract.defaultAccount = '0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe';

// Instance
contractInstance.defaultAccount = '0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe';

// All
web3.eth.defaultAccount = '0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe';
