To enable UMI transaction brand to Solane

As a developer who uses Metaplex platform to create and manage NFT, it is necessary to understand how to interact with Blockchain Solan. One of the key features of Metaplex is its ability to support browser wallets that allow users to sign transactions without having to use a physical device or account in the recent chain of the application (DAPP).

In this article, we will focus on enabling UMI’s browser transaction transactions on Solane using JavaScript. We will also cover all the errors that may occur, and we will guide how to solve them.

assumptions

Before immersing the code, make sure you have:

• Metaplex account with DAPP functional chain

• Solana node installed on a local machine (or connected to a remote node)

• JavaScript environment set to compile and run our code

code

Here is an example of how to create a token NFT using UMI transaction transaction in your browser:

`Javascript

Const {web3} = require (‘web3’);

Const {deploy, sigmumint} = require (‘@metaplex/fabric’);

Const Web3 = New Web3 (new Web3.Providers.httpprovider (‘

// Define Metadata NFT

Const nftmetadata = {

ID: “0x …”,

Name: “My Awesome NFT”,

Description: “Collectable digital asset”,

Image: ‘

};

// Create a new coin for our token NFT

Async function createmint () {

Const Mintid = expect Deploy (‘Mint’, Web3, NFTMETADATA);

Console.log (Mint -created with ID $ {Mintid});

}

// Define the address of our browser wallet

Const Browserwalletaddress = ‘0x …’;

// function to sign UMI transactions using your browser’s wallet

Async Signumint function () {

Const Signature = Acait Deploy (‘Signi’, Web3, NFTMETADATA);

Console.log (signed UMI transaction with ID $ {signature.id});

}

// Mainflow of implementation

Createmint ();

Sigmumint ();

// handling errors: If you encounter any problems while creating mint or signing UMI transactions,

// This will be logged in to the console.

Console.error (‘Error creates a coin or signature of UMI transactions:’);

`

troubleshooting

If you are experiencing errors while trying to create a coin or signing UMI transaction, make sure that:

1.

• Your solana node is properly configured to provide the necessary end point of RPC (https: // api.solana.com/RPC).

3.

Routine Errors

Here are a few common mistakes that may occur during mint formation or signed UMI transactions:

* Signature of UMI error transaction : This error usually occurs when the function of “Deployment” does not create a UMI signature. Check the output of “Sigmumint`, where you will find any protocol commands related to this problem.

* Error creating a mint : If you encounter a problem while creating mint, make sure that your browser’s wallet address is correct and corresponds to your Metaplex account.

According to these instructions and troubleshooting tips, you should be able to successfully create and sign UMI transactions using a Solane browser wallet.
