Problem Metamask: I can’t load an Ethereum object from Metamask React
When working with Metamask in React, developers of a problem encounter loading Ethereum objects from your wallet. In this article we will dive into the problem and provide a solution.
Problem: Loading an Ethereum object from Metamask React
The code of the code you have done is a common example of how to manage changes in metamask accounts. However, when trying to load an Ethereum object from your wallet using ethereum.request ({method: 'eth_accounts'}), you will find the following error:
`
I can’t load an Ethereum object
`
Why this error occurs
The error occurs because ethereum.request ('eth_accounts') is not a valid method for loading Ethereum objects in Metamask React. The right method to obtain the address of Ethereum from your wallet is ethereum.etherum accounts () or ethereum.etherum bilant (). However, these methods return a range of Ethereum accounts that do not contain a specific object.
Solution: Using ethereum.etherum accounts ()
To load a specific Ethereum account, you can use ethereum.etherum accounts () :::
`Typescript
Ethereum.request ({method: 'eth_accounts'})
.Then (accounts => {
Const specific account = accounts [0];
// Use a specific account to obtain your private key or other relevant data
})
.catch ((err: any) => {
Console.error (ERR); // handle any errors that may occur when loading an Ethereum object
});
Adding a listener of account changes
To process changes in your accounts, you can add events to the “Ethereum:
Typescript
Ethereum.on ('Foreign Foreign Affairs), (New Accounts) => {
Const specific account = new accounts [0];
// Use a specific account to obtain your private key or other relevant data
});
Full Example
Here is a complete example that shows how to load Ethereum from Metamask React and Ranking in accounts:
`Typescript
Import * as a metamascus reacts from "Metamask React";
Interface bills {
[Key: String]: Any;
}
Const account must = async (new accounts) => {
Const specific account = new accounts [0];
// Use a specific account to obtain your private key or other relevant data
};
Ethereum.on ('CanceChanged', CANCESCHANGED);
Ethereum.request ({method: 'eth_accounts'})
.Then ((accounts) => {
Console.log (accounts);
})
.catch ((err: any) => {
Console.error (ERR); // handle any errors that may occur when loading an Ethereum object
});
In this example, we define the Accounts data interface and create AccountsChanged 'for processing changes in accounts. We then attach this feature as a listener of events to theethereum ‘object using the“ On (‘ AccountsChanged ‘) method .
Conclusion
By understanding the problem and providing solutions, we facilitated the development of Ethereum objects from Metamask and to manage changes in accounts. Be sure to replace the code excerpt with your own implementation and updateethereum.on (‘foreign foreign), (new accounts) => {…}); a line that suits your particular use case.
