TOKEN metadata with a metabulous and token2022
In Solana, the preservation of metadata can be a bit difficult for a certain token. However, the use of the metamplex expansion or the TOKEN2022 -API offers a reliable way to call up this information. In this article we will examine how these tools use together to get the metadata for a token in the Solana network.
Requirements
Before driving, make sure that you have installed the necessary dependencies:
`Bash
NPM Install @Solana/Web3.js @Metaplex-Js/Token2022
or
`Bash
Garn @solana/web3.js @metaplex-js/token2022 add
The script: get token metadata
In the following you will find an example script that shows how the metabulous expansion and the TOKEN2022 -API are used to obtain token metadata.
`JavaScript
Import {Connection, Publickey} from '@Solana/Web3.js';
Import {gettkenmetadata} from '@metaplex-js/token2022';
Async function gettkenmetadata (tokenid: string) {
// Create a connection to the Solana network
Connection = new Connection ();
attempt {
// Call the token metadata with the token2022 -api
Const Metadata = WaTte Gettkenmetadata (connection, tokenid);
Return metadata;
} Catch (error) {
console.error (error);
Return zero;
}
}
// sample use
Gettkenmetadata ('Sandx-USD'). Then ((metadata) => {
if (metadata! == zero) {
console.log (metadata);
} differently {
console.log ("No token metadata found for Sandx-USD");
}
});
`
How it works
The "Gettkenmatata" function takes a clear identifier (tokenid) as an argument. It creates a connection to the Solana network withSolana/web3.js. The token2022 -API is then used to get the metadata for the specified token.
The following happens under the bonnet:
- The "Gettkenmetadata" function sends a Get request to the TOKEN2022 -API endpoint with the "tokenid" parameter as a query.
- The answer contains the token metadata, which is then returned by the function.
Note : Make sure that you have replaced "Sandx-USD' by the actual ID of the token for which you want to get metadata.
Diploma
Receiving token metadata using Metablex and TOKEN2022 offers a reliable way to obtain this information in the Solana network. If you follow the above script, you can easily call up metadata for each token by providing its clear identifier. Remember to replace the "tokenid" with the actual ID of the token for which metadata wants to call up.
