Metamask: WalletConnect Mobile Wallets with Custom Chains
As a developer building applications on the Ethereum blockchain, it is crucial to you to control your users’ funds. One popular solution to achieve this is to use WalletConnect mobile wallets, which enable seamless interaction between your application and users’ MetaMask accounts. However, one of the limitations of standard WalletConnect implementations is the inability to support custom networks.
In this article, we will show you how Metamask offers a solution to bypass these limitations by enabling 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 application and users’ MetaMask accounts. It uses the WebSocket protocol for low-latency communication and enables the creation of custom wallets that can communicate with multiple networks simultaneously.
Problem: Limited support for custom networks
Standard implementations of WalletConnect rely on the ERC-20 Ethereum standard, which limits the ability of a wallet to interact with other blockchains. This limitation is due to the fact that many popular wallets only support certain types of networks and do not allow for seamless interaction between different chains.
To overcome this limitation, a solution is needed that can handle multiple chain interactions. This is where Metamask comes in – an open-source decentralized wallet provider that allows developers to create custom wallet connections to any blockchain.
Metamask: A Custom Wallet Solution
Metamask is the answer to your prayers! With built-in support for custom chains, you can create wallet connections that can interact with multiple networks simultaneously. Here are some key features of Metamask:
- Support for multi-chain interactions: Metamask allows developers to create wallet connections to any blockchain, including Ethereum, Binance Smart Chain (BSC), Polygon (MATIC), and more.
- Support for custom chains
: 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 having to rely on third-party centralized providers.
Sample Use Case: Creating a Custom On-Chain Wallet
To illustrate the capabilities of Metamask, let’s consider an example use case. Let’s say you’re building an application that allows users to interact with multiple blockchains. You want to provide a seamless user experience by creating custom wallet connections to 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 wallet creation({
accounts: [‘0x…’],
keyId: ‘some-key-id’,
network: ‘mainnet’,
});
// Define custom chain configurations for each blockchain
constants chains = {
mainnet: {
// Configure wallet connection to Ethereum mainnet
url: ‘
type: ‘ethereum’,
},
bachelor’s: {
// Configure wallet connection to Binance Smart Chain (BSC)
url: ‘
type: ‘bsc’,
},
};
// Interacting with custom chains using WalletConnect WebSockets
const account2 = await wallet creation({
accounts: [‘0x…’],
keyId: ‘some-key-id’,
network: ‘mainnet’,
});
account.connect(chains.mainnet).then((connectedAccount) => {
account2.connect(chains.bsc).
