Remove the specific wallet service provider used in Web3 Dapp
With the increasing acceptance of decentralized applications (Dapps), the blockchain platform is becoming increasingly important to monitor and manage underwave relationships. One community noticed which specifier Wrets during a specific DAPP recovery. In this article, we examine how to implement a solution using web3 libraries in JavaScript.
The current approach
You can find it in the “Ethereum and” Web3 “codebase, but you do not provide any system which waste provider was used to connect. The reason for this is that both libraries have multiple wallet providers in a Weser compartment.
Solution Overview
To solve this problem, we use the ability of web3.js to detect and analyze the wall removal of the Ethereum wallet. We’s Creet is a customs docking that is best provided by a specific wall and returns the names as an array.
Implementation
`javacript
Const Etherum = Window.ethereum;
const web3 = window.web3;
// function to detect and return the wall as an array
The Function of Getwalletprovids () {
Const service provider = etherum.currentProvider;
Const walls = [];
if (provid && service provider.getaccounts ()) {
for (Const account is a service provider.getaccounts ()) {
const Wallname = web3.eth.accounts.fromrawhash (account.rawhash);
Wolts.push (Wallname);
}
}
Report of the walls;
}
// feature to detect a particular wall update
Function Detectwalletprovider (service providers, Walletname) {
Const matchingproviders = providers.filter (provid => service provider.Name == Watletname);
if (MatchingProvids.Length> 0) {
Accountation Providers [0] .Name; // return the name from the appropriate service provider
} other
The account is zero;
}
}
// using examples:
CONST WALLS = Getwalletproviders ();
console.log (wallets); // output: ['...']
Const Etherumprovider = Etherum.currentperder;
Const Web3provider = window.web3.currentprovider;
Const Wallname = Detectwalletprovider (wallet, '0x ...' '); // re -place the actual wall name
if (Wallname! == zero) {
Console.log (joined to $ {Walletname} esting Etherum);
} other
console.log (‘no adequate service provider’);
}
`
Explanation
In this implementation:
1.
2.
- The “Detectwalletperder ()” feature enters a series of service objects and a specified wall name as an input. It filters the basics of the list under the name of service. If the match is rooted, it will bear the name of the appropriate service provider; Otherwise, he returns to “null”.
- We log the resole.
Conclusion
If you use this custom solution using Web3.Js and Deting Wall refreshing providers, you can effectively get to the WASSE service provider. This approach allows you to manage multiple service providers on your Wesers, while still providing a smooth Weser experience.
