铸造到指令
创建新代币并将其存入指定账户。只有铸币权限持有者可以执行此操作。
在我们铸造任何代币之前,我们需要已经完成以下操作:
- 初始化一个
Mint
账户,并持有mintAuthority
- 初始化一个
Token
账户或Associated Token
账户,用于接收铸造的代币
原始指令
通过仅使用“原始”指令而不进行任何抽象,铸造代币的操作如下所示:
const destination = Keypair.generate();
const tokenAccount = await getAssociatedTokenAddress(
mint.publicKey,
destination.publicKey,
);
// Create ATA creation instruction
const createAtaInstruction = createAssociatedTokenAccountIdempotentInstruction(
keypair.publicKey, // payer
tokenAccount, // associated token account address
destination.publicKey, // owner
mint.publicKey, // mint
);
// Mint tokens to ATA
const mintToInstruction = createMintToInstruction(
mint.publicKey, // mint
tokenAccount, // destination
keypair.publicKey, // mint authority
1_000e6, // amount of tokens
);
const transaction = new Transaction().add(
createAtaInstruction,
mintToInstruction,
);
const signature = await sendAndConfirmTransaction(connection, transaction, [keypair]);
console.log(`Token accounts created and tokens minted! Check out your TX here: https://explorer.solana.com/tx/${signature}?cluster=devnet`);
抽象指令
以下是使用 mintTo()
指令抽象后的操作:
const destination = Keypair.generate();
const ata = await getOrCreateAssociatedTokenAccount(
connection,
keypair,
mint,
destination.publicKey
);
console.log(`This is your ATA: ${ata.address}!`)
let tx = await mintTo(
connection,
keypair,
mint,
ata.address,
keypair.publicKey,
1e6,
);
console.log(`Succesfully Minted!. Transaction Here: https://explorer.solana.com/tx/${tx}?cluster=devnet`)
