Metamask: How do I generate a metamask mobile deep link programmatically?
Programmates A Metamask Mobile Deep Link generate
As a developer, you are probably familiar with the popular metamask letter bag and its ability to create deep links for your dapps. Sometimes, however, they want to generate these links program -controlled instead of relying on manual inputs from users. In this article we will examine how this works programmatically.
Overview
In order to generate a mobile mobile depth connection link program -controlled, you can use the “Web3” library to create an item pockets -URL and then replace placeholder in the resulting characters with your own values.
Step 1: Create a new wallet -URL
First create a new items -URL with the Web3 -API from Metamask. You can do this by executing the following JavaScript code:
`JavaScript
Const web3 = demands (“web3”);
Const Balleturl Provider = Require (“Metamask-Depeplinks provider”);
// replace your own metamask provider details
Const Provideraddress = “0xyourwallertaddresse”;
Const Providensecret = “YourWalletetsecret”;
Const BalleturlProvider = new Balleturl Provider ({{{{{{
Provider: {
Address: Provideraddress,
Secret: Providecret,
},
});
// generate a random token for the DAPP
Const tokenid = math.floor (math.random () * 1000) .tostring ();
// Create a new wallet -URL with space owners for your own values
Const Walleturl = {walleturlprovider.getwalleturl ()}/dapp/$ {tokenid};
`
Step 2: Replace placeholder in the items -URL
After you have generated the items -Url, you must replace all placeholder (e.g. `{Walketurl}} ') with your own values. You can do this by iterated and replaced by a value.
Here is an example of how you can replace placeholder:
JavaScript
Const Walleturl = {walleturlprovider.getwalleturl ()}/dapp/$ {tokenid};
// Replace $ {WalleturlProvider.getWalleturl ()} with your own provider address
Const Walmeturl = Walmeturl.Replace (“$ {WalleturlProvider.getwalleturl ()}”, “$ {provideraddress});
// $ {tokenid} replace with your own dapp -id -id (e.g. "tipme.cash"))
Const tokenid = "tipme.cash";
Const Balleturl = Balleturl.Replace ("$ {tokenid}", tokenid);
Step 3: Get the URL
After you have replaced all placeholder, you must receive the resulting URL using Metamask’s Web3 API. You can do this by calling the “Getwallerturlmethod on the instance of Walleturl Provider:
JavaScript
Const BalleturlProvider = new Balleturl Provider ({{{{{{
Provider: {
Address: Provideraddress,
Secret: Providecret,
},
});
// you get the resulting URL with WalleturlProvider.Getwalleturl ()
Const Balleturl = BalleturlProvider.Getwalleturl ();
`
put together everything
Here is an example of how you could put everything together:
`JavaScript
Const web3 = demands (“web3”);
Const Balleturl Provider = Require (“Metamask-Depeplinks provider”);
// replace your own metamask provider details
Const Provideraddress = “0xyourwallertaddresse”;
Const Providensecret = “YourWalletetsecret”;
Const BalleturlProvider = new Balleturl Provider ({{{{{{
Provider: {
Address: Provideraddress,
Secret: Providecret,
},
});
// generate a random token for the DAPP
Const tokenid = math.floor (math.random () * 1000) .tostring ();
// Create a new wallet -URL with space owners for your own values
Const Walleturl = {walleturlprovider.getwalleturl ()}/dapp/$ {tokenid};
// Replace $ {WalleturlProvider.getWalleturl ()} with your own provider address
Const Walmeturl = Walmeturl.Replace (“$ {WalleturlProvider.getwalleturl ()}”, “$ {provideraddress}`);
// $ {tokenid} replace with your own dapp -id -id (e.g. “tipme.cash”))
Const tokenid = “tipme.cash”;
Const Balleturl = Balleturl.Replace (“$ {tokenid}”, tokenid);
// you get the resulting URL with WalleturlProvider.Getwalleturl ()
Const Balleturl = Balleturl Provider.
