Problem with the Metamk supplier configuration: just one account on the list
While trying to configure Euter.js with MetamSk, there is a common problem when only web3provider configured only one account. This article will deepen the root cause of this problem and provide a step -by -step solution.
The problem:
When MetamSk is used as his Ethereum supplier, it is possible to detect only one account (or wallet). This can happen for several reasons, including:
- Incorrect web3provider configuration : Be sure to establish the correct function
Initprovider ()and correctly initialize all units.
- Problems with the synchronization of the MetamSk portfolio
: Metamask wallets cannot be properly synchronized with their local portfolio, which leads to a single account.
- Web3provider configuration : Make sure the web3provider is configured to use a different supplier or wallet.
Decision:
To solve this problem, follow these steps:
Step 1: Verify the web3provider configuration
Verify that the ‘Initprovider () function is initialized correctly with the providers of Ethereum and the Metamascus:
`JavaScript
Initprovider () {
Const ethhereum = window ['ethereum'];
Const metamask = window ['metamask'];
// Verify the two cases of the supplier
If (Ethereum && Metamask) {
This.provider = {
Type: 'Web3',
Options: {
Supplier: Ethereum,
},
};
// Initialization of the Web3Provider copy
This.web3Provider = New Web3 (This.provider);
} Others {
Console.error ("Only one account is indicated by the configured web3provider");
}
}
Step 2: Verify the synchronization of Metamk's portfolio
Verify that Metamk's portfolios are correctly synchronized with the local portfolio:
JavaScript
// Initialize Metamk supplier
const metamaskprovider = window ['metamask'];
If (metamaskprovider) {
// Configure the listener for Ethereum Blockchain Events
metamaskprovider.on ('chainready', () => {
// Your local Ethereum portfolio is properly synchronized.
Console.log ("its local Ethereum portfolio has been successfully synchronized");
});
// Initialize the web3provider copy with Metamask
This.provider = new web3 (Metamkprovider);
}
Step 3: Configure Web3Provider
Be sure to establish the correct functionInitprovider ()and correctly initialize all dependencies:
JavaScript
Initprovider () {
Const ethhereum = window ['ethereum'];
Const metamask = window ['metamask'];
// Verify the two cases of the supplier
If (Ethereum && Metamask) {
This.provider = {
Type: 'Web3',
Options: {
Supplier: Ethereum,
},
};
// Initialize the web3provider copy with Metamask
This.web3Provider = New Web3 (This.provider);
} Others {
Console.error ("Only one account is indicated by the configured web3provider");
}
}
`
Conclusion
After these steps, you must be able to solve the problem and make sure that Ethereum and Metamask suppliers are correctly configured. Be sure to verify the synchronization of the portfolio and configure the correct web3provider settings for the optimal integration Euters.js with Metamask.
