Catatan

Kamu tidak bisa mint sebuah NFT dari creator yang berbeda dari wallet-mu. Jika kamu mengalami creator issues, maka pastikan metadata-mu mendaftarkanmu sebagai creator.

Cara Mendapatkan Metadata NFT

Metaplex NFTs memiliki metadata yang disimpan di Arweave. Untuk mendapatkan metadata Arweave, kamu harus mendapatkan Metaplex PDA dan decode account data.

import { Metaplex, keypairIdentity } from "@metaplex-foundation/js";
import { Connection, clusterApiUrl, Keypair, PublicKey } from "@solana/web3.js";

(async () => {
  const connection = new Connection(clusterApiUrl("mainnet-beta"));
  const keypair = Keypair.generate();

  const metaplex = new Metaplex(connection);
  metaplex.use(keypairIdentity(keypair));

  const mint = new PublicKey("Ay1U9DWphDgc7hq58Yj1yHabt91zTzvV2YJbAWkPNbaK");

  const nft = await metaplex.nfts().findByMint(mint);

const nft = await metaplex.nfts().findByMint(mint);

console.log(nft.metadata);

Cara Mengetahui Pemilik Sebuah NFT

Jika kamu memiliki mint key dari sebuah NFT, kamu bisa mencari pemilik terkini dengan mengintip di token account terbesar untuk mint key tersebut.

Mengingat bahwa NFTs memiliki 1 supply, dan mereka tidak dapat dibagi, yang artinya suatu token hanya dapat dimiliki oleh satu token account setiap kalinya, sementara itu semua token account lainnya untuk mint key tersebut memiliki saldo 0.

Ketika token account terbesar sudah diidentifikasi, kita bisa mengambil pemiliknya.

Cara untuk mengambil NFT Mint Addresses

Jika kamu tau public key dari Candy Machine, kamu bisa mendapatkan daftar semua NFT mint addresses yang dihasilkan dari Candy Machine tersebut dengan menggunakan code berikut. Ingat bahwa kita bisa menggunakan filter memcmp karena, di v1, address dari Candy Machine selalu creator pertama.

Candy Machine V2

Jika kamu menggunakan Candy Machine v2, maka pertama-tama kamu harus memiliki akses ke “Candy Machine Creator” address yang merupakan suatu PDA simpel yang menggunakan candy_machine dan Candy Machine v2 address sebagai seeds. Ketika kamu sudah dapat creator address, kamu bisa memakainya dengan cara yang sama dengan v1.

Cara Mendapatkan Semua NFT dari Suatu Wallet

Ketika mendapatkan semua NFT dari sebuah wallet, kamu harus mendapatkan semua token account dan kemudian parse mana yang merupakan NFT. Ini bisa dilakukan denganfindDataByOwneropen in new window dari Metaplex js library.
