Metamask: WalletConnect Mobile Wallets with Custom Chains
As a developer building applications on the Ethereum blockchain, having control over your user’s funds is crucial. One popular solution for achieving this is by using WalletConnect mobile wallets, which enable seamless interactions between your app and users’ MetaMask accounts. However, one limitation of standard WalletConnect implementations is their inability to support custom networks.
In this article, we’ll explore how Metamask provides a solution to overcome these limitations, allowing you to create wallet connections with custom chains.
What is WalletConnect?
WalletConnect is an open-source protocol that enables peer-to-peer interactions between your app and users’ MetaMask accounts. It uses WebSockets for low-latency communication and allows for the creation of custom wallets, which can interact with multiple networks simultaneously.
The Problem: Limited Custom Network Support
Standard WalletConnect implementations are built on top of Ethereum’s ERC-20 standard, which restricts a wallet’s ability to interact with other blockchain networks. This limitation arises from the fact that many popular wallets only support certain network types and do not allow for seamless interactions between different chains.
To overcome this limitation, you need a solution that can handle multiple chain interactions. That’s where Metamask comes in – a decentralized, open-source wallet provider that empowers developers to create custom wallet connections with any blockchain network.
Metamask: A Custom Wallet Solution
Metamask is the answer to your prayers! With its built-in support for custom chains, you can create wallet connections that interact with multiple networks simultaneously. Here are some key features of Metamask:
- Support for Multiple Chain Interactions
: Metamask allows developers to create wallet connections with any blockchain network, including Ethereum, Binance Smart Chain (BSC), Polygon (MATIC), and more.
- Custom Chain Support: With Metamask, you can define your own custom chain configurations and interact with other chains using WalletConnect WebSockets.
- Decentralized and Open-Source: Metamask is a decentralized wallet provider that allows developers to create custom wallets without relying on centralized third-party providers.
Example Use Case: Creating a Custom Chain Wallet
To illustrate the capabilities of Metamask, let’s consider an example use case. Suppose you’re building an application that allows users to interact with multiple blockchains. You want to provide a seamless experience for your users by creating custom wallet connections with each blockchain. With Metamask, you can define custom chain configurations and interact with other chains using WalletConnect WebSockets.
“`javascript
// Import Metamask and create a new wallet instance
import { createWallet } from ‘ metamask ‘ ;
const account = await createWallet({
accounts: [‘0x…’],
keyId: ‘some-key-id’,
network: ‘mainnet’,
});
// Define custom chain configurations for each blockchain
const chains = { const chains = {
mainnet: {
// Set up wallet connection with Ethereum mainnet
url: ‘
type: ‘ethereum’,
},
bsc : {
// Set up wallet connection with Binance Smart Chain (BSC)
url: ‘
type: ‘bsc’,
},
};
// Interact with custom chains using WalletConnect WebSockets
const account2 = await createWallet({
accounts: [‘0x…’],
keyId: ‘some-key-id’,
network: ‘mainnet’,
});
account . connect ( chains . mainnet ) then ( ( connectedAccount ) => { ;
account2 . connect ( chains . bsc ) .
