Metamask Provider Configuration Issue: Only One Account Listed
As you attempt to configure Ethers.js together with Metamask, a common issue arises when only one account is listed by the configured Web3Provider. This article will delve into the root cause of this problem and provide a step-by-step solution.
The Problem:
When using Metamask as your Ethereum provider, it’s possible that only one account (or wallet) is being detected. This can happen due to various reasons, including:
- Incorrect Web3Provider configuration: Make sure you have set the correct
initProvider()function and properly initialized all dependencies.
- Metamask wallet synchronization issues: Metamask wallets may not sync correctly with your local wallet, leading to only one account being listed.
- Web3Provider settings: Ensure that the Web3Provider is configured to use a different provider or wallet.
Solution:
To resolve this issue, follow these steps:
Step 1: Verify the Web3Provider configuration
Check if the initProvider() function is properly initialized with both Ethereum and Metamask providers:
initProvider() {
const ethereum = window['ethereum'];
const metamask = window['metamask'];
// Check for both provider instances
if (ethereum && metamask) {
this.provider = {
type: 'web3',
options: {
provider: ethereum,
},
};
// Initialize the Web3Provider instance
this.web3Provider = new Web3(this.provider);
} else {
console.error('Only one account is listed by the configured Web3Provider');
}
}
Step 2: Check Metamask wallet synchronization
Verify that Metamask wallets are syncing correctly with your local wallet:
// Initialize the MetaMask provider
const metamaskProvider = window['metamask'];
if (metamaskProvider) {
// Set up a listener for Ethereum blockchain events
metamaskProvider.on('chainReady', () => {
// Your local Ethereum wallet is synced correctly.
console.log('Your local Ethereum wallet has been synced successfully.');
});
// Initialize the Web3Provider instance with Metamask
this.provider = new Web3(metamaskProvider);
}
Step 3: Configure the Web3Provider
Make sure to set the correct initProvider() function and properly initialize all dependencies:
initProvider() {
const ethereum = window['ethereum'];
const metamask = window['metamask'];
// Check for both provider instances
if (ethereum && metamask) {
this.provider = {
type: 'web3',
options: {
provider: ethereum,
},
};
// Initialize the Web3Provider instance with Metamask
this.web3Provider = new Web3(this.provider);
} else {
console.error('Only one account is listed by the configured Web3Provider');
}
}
Conclusion
By following these steps, you should be able to resolve the issue and ensure that both Ethereum and Metamask providers are properly configured. Remember to verify wallet synchronization and set up correct Web3Provider configurations for optimal Ethers.js integration with Metamask.
