Here is a complete guide on how to import the NFTS program in Metamask, a popular cryptocurrency portfolio:
What is Metamk?
Metamask is an extension of the browser and an office application that allows users to store, manage and interact with their digital assets, including cryptocurrencies such as Ethereum (ETH) and other blockchain -based tokens. It provides a safe way to transfer funds, store private keys and access to decentralized financing applications (DEFI).
Import NFT to Metamk
To import through the NFTS program in METAMASK, you must use the following configuration:
- Use the web library3.js : You must include the web3.js library in your project to interact with the Blockchain and NFT Ethereum markets.
- Create a JSON object with NFT metadata : NFT metadata include information such as contract address, token name, symbol and mint date. You can create a JSON object that contains these metadata using a tool like
nftmetadata.ioor ipfsjson.
- Use the Metamask API to import NFT : Once the JSON Metadata object is, you must use MetamSk API to import it to your wallet.
Step by step guide
Here is an example of how to import a NFT to MetamSk by program using web3.js and MetamSk's API:
- Install web3.js
: Install the web library.
- Create a JSON object with NFT metadata : Use a tool likenftmetadata.io
or ipfsjsonto create a JSON object containing NFT metadata.
`JSON
{
"Contrantess": "0x ... contract_address ..."
"Tokenname": "... token_name ..."
"Symbol": "... token_symbol ..."
"MINTDATE": "... MINT_DATE ..."
}
'
- Create an object with web3.js : Create a new object containing the web3.js library and the JSON object that created in step 2:const web3 = new web3 ();
Const nftobject = {
Hirderddress: ‘0x … contract_address …’,
Tokenname: ‘… token_name …’,
Symbol: ‘…’ // Use an empty chain instead of the real symbol if it is not available
}; `
- Import NFT to MetamSk : Use the
web3.eth.sendsignedMessage» method to send a signed message to Metamk API, which will import NFT metadata in your wallet:
JavaScript
Const web3 = new web3 ();
nftobject.contractaddress = '0x ... contract_address ...'; // Update the contract address here
nftobject.tokenneme = '... token_name ...'; // Update Token's name
Web3.eth.sendsignedMessage ('Metamask', Json.stringify (nftobject)). then ((result) => {
console.log (result); // Exit: {Message: "NFT Imported successfully"}
});
'
Tips and variations
- You can customize NFT metadata to include additional information, such as a personalized name or symbol.
- If you have an existing metamask portfolio with private keys, you may have to update these keys before importing the NFT.
- You can also use other libraries such as "Ethers.js" orERC721.json” to create and administer NFT per program.
Conclusion
The programmatic import of NFT to Metamask is a powerful way to extend the functionality and control of its wallet. Following these steps, you can import metadata from external sources and update your wallet with new information. However, keep in mind that this method requires some technical experience and may require additional configuration and configuration.
