Provider Metamask Configuration Issue: Only one account is displayed
A common issue when trying to configure Ethers.js with Metamask is when the configured Web3Provider displays only one account. In this article, we will take a closer look at the cause of this issue and provide a detailed solution.
Problem:
When using Metamask as your Ethereum provider, it is possible that only one account (or wallet) is detected. This can happen for a variety of reasons, including:
- Incorrect Web3Provider configuration
: Make sure you have set the correct
initProvider()function and initialized all dependencies correctly.
- Metamask wallet sync issues: Metamask wallets may not sync properly with the local wallet, which can result in only one account being displayed.
- Web3Provider Settings
: Make sure that Web3Provider is configured to use a different provider or wallet.
Solution:
To resolve this issue, follow these steps:
Step 1: Verify Web3Provider Configuration
Check that the initProvider() function is initialized correctly for both Ethereum and Metamask providers:
initProvider() {
const ethereum = window['ethereum'];
const metamask = window['metamask'];
// Check both instances of the provider
if (ethereum && metamask) {
this.provider = {
type: 'web3',
options: {
provider: ethereum,
},
};
// Initialize Web3Provider instance
this.web3Provider = new Web3(this.provider);
} else {
console.error('Configured Web3Provider displays only one account');
}
}
Step 2: Verify Metamask Wallet Sync
Verify that Metamask wallets are syncing properly with your local wallet:
// Initialize MetaMask Provider
const metamaskProvider = window['metamask'];
if (metamaskProvider) {
// Configuring the Ethereum blockchain event listener
metamaskProvider.on('chainReady', () => {
// Your local Ethereum wallet is successfully synced.
console.log('Your local Ethereum wallet has been successfully synced.');
});
// Initialize the Web3Provider instance with Metamask
this.provider = new Web3(metamaskProvider);
}
Step 3: Configure the Web3Provider
Make sure you have set the correct “initProvider()” function and initialized all dependencies correctly:
initProvider() {
const ethereum = window['ethereum'];
const metamask = window['metamask'];
// Check both provider instances
if (ethereum && metamask) {
this.provider = {
type: 'web3',
options: {
provider: ethereum,
},
};
// Initialize a Web3Provider instance with Metamask
this.web3Provider = new Web3(this.provider);
} else {
console.error('Configured Web3Provider shows only one account');
}
}
Conclusion
By following these steps, you should be able to troubleshoot the issue and make sure that both the Ethereum and Metamask providers are configured correctly. Don’t forget to check your wallet sync and configure the correct Web3Provider configurations to ensure optimal Ethers.js integration with Metamask.
