I have some problem in updating Metaplex NFT Metadata. I used @metaplex/js and this is my code.
import { programs } from '@metaplex/js';
export const updateMetadataV1 = async () => {
let { metadata : {Metadata, UpdateMetadata, MetadataDataData, Creator} } = programs;
let signer = loadWalletKey(keyfile);
let nftMintAccount = new PublicKey("EC8gGdtVFDoTf3vEGbLvPp7SVWta2xQrs99iWMbaFrdE");
let metadataAccount = await Metadata.getPDA(nftMintAccount);
const metadat = await Metadata.load(solConnection, metadataAccount);
let newUri = "https://arweave.net/my arweave address";
if (metadat.data.data.creators != null) {
const creators = metadat.data.data.creators.map(
(el) =>
new Creator({
...el,
}),
);
let newMetadataData = new MetadataDataData({
name: metadat.data.data.name,
symbol: metadat.data.data.symbol,
uri: newUri,
creators: [...creators],
sellerFeeBasisPoints: metadat.data.data.sellerFeeBasisPoints,
})
const updateTx = new UpdateMetadata(
{ feePayer: signer.publicKey },
{
metadata: metadataAccount,
updateAuthority: signer.publicKey,
metadataData: newMetadataData,
newUpdateAuthority: signer.publicKey,
primarySaleHappened: metadat.data.primarySaleHappened,
},
);
let result = await sendAndConfirmTransaction(solConnection, updateTx, [signer]);
console.log("result =", result);
}
}
The transaction result has no error, it means transaction success. I checked it on Solana Explorer. But the metadata doesn't change. What's the matter?
To Solve this issue this code can be used, This is a low-level code that uses the mpl-token-metadata npm package to call the on-chain updateMetadata Function.
import { Wallet } from "@project-serum/anchor";
import * as anchor from "@project-serum/anchor";
import {createUpdateMetadataAccountV2Instruction,DataV2,UpdateMetadataAccountV2InstructionArgs,UpdateMetadataAccountV2InstructionAccounts} from "@metaplex-foundation/mpl-token-metadata"
const fs = require("fs");
(async() => {
// This is the Update Authority Secret Key
const secretKey = fs.readFileSync(
"/Users/pratiksaria/.config/solana/id.json",
"utf8"
);
const keypair = anchor.web3.Keypair.fromSecretKey(
Buffer.from(JSON.parse(secretKey))
);
const endpoint = "https://metaplex.devnet.rpcpool.com/";
const connection = new anchor.web3.Connection(endpoint);
const wallet = new Wallet(keypair);
console.log("Connected Wallet", wallet.publicKey.toString());
const TOKEN_METADATA_PROGRAM_ID = new anchor.web3.PublicKey(
"metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s"
);
// You have to enter your NFT Mint address Over Here
const mintKey = new anchor.web3.PublicKey("5iSxT33FyHWsnb8NYSytY17TTXfkFn62FiCyFVFxYhqY");
const [metadatakey] = await anchor.web3.PublicKey.findProgramAddress(
[
Buffer.from("metadata"),
TOKEN_METADATA_PROGRAM_ID.toBuffer(),
mintKey.toBuffer(),
],
TOKEN_METADATA_PROGRAM_ID
);
// BTW DeGods is my FAV collection although i cant afford one 🥲
const updated_data: DataV2 = {
name: "DeGods",
symbol: "DG",
uri: "https://metadata.degods.com/g/4924.json",
sellerFeeBasisPoints: 1000,
creators: [
{
address: new anchor.web3.PublicKey(
"CsEYyFxVtXxezfLTUWYwpj4ia5oCAsBKznJBWiNKLyxK"
),
verified: false,
share: 0,
},
{
address: wallet.publicKey,
verified: false,
share: 100,
},
],
collection: null,
uses: null,
};
const accounts:UpdateMetadataAccountV2InstructionAccounts = {
metadata: metadatakey,
updateAuthority: wallet.publicKey,
}
const args:UpdateMetadataAccountV2InstructionArgs = {
updateMetadataAccountArgsV2: {
data: updated_data,
updateAuthority: wallet.publicKey,
primarySaleHappened: true,
isMutable: true,
}
}
const updateMetadataAccount = createUpdateMetadataAccountV2Instruction(
accounts,
args
);
const transaction = new anchor.web3.Transaction()
transaction.add(updateMetadataAccount);
const {blockhash} = await connection.getLatestBlockhash();
transaction.recentBlockhash = blockhash;
transaction.feePayer = wallet.publicKey;
const signedTx = await wallet.signTransaction(transaction);
const txid = await connection.sendRawTransaction(signedTx.serialize());
console.log("Transaction ID --",txid);
})()
