我想使用Solana Web3.js发送已部署令牌而不是Sol,但我不知道如何操作。我已经花了很长时间寻找官方文档,但是找不到。如果您有任何相关信息,能否请告诉我?谢谢

现有答案的问题在于它们只向您展示了如何首先创建一个新的自定义代币,然后执行从一个钱包到另一个钱包的转账。这里我将展示如何使用现有的自定义代币完成此操作。
import { Token, TOKEN_PROGRAM_ID } from "@solana/spl-token";
import { web3, Wallet } from "@project-serum/anchor";
async function transfer(tokenMintAddress: string, wallet: Wallet, to: string, connection: web3.Connection, amount: number) {
const mintPublicKey = new web3.PublicKey(tokenMintAddress);
const mintToken = new Token(
connection,
mintPublicKey,
TOKEN_PROGRAM_ID,
wallet.payer // the wallet owner will pay to transfer and to create recipients associated token account if it does not yet exist.
);
const fromTokenAccount = await mintToken.getOrCreateAssociatedAccountInfo(
wallet.publicKey
);
const destPublicKey = new web3.PublicKey(to);
// Get the derived address of the destination wallet which will hold the custom token
const associatedDestinationTokenAddr = await Token.getAssociatedTokenAddress(
mintToken.associatedProgramId,
mintToken.programId,
mintPublicKey,
destPublicKey
);
const receiverAccount = await connection.getAccountInfo(associatedDestinationTokenAddr);
const instructions: web3.TransactionInstruction[] = [];
if (receiverAccount === null) {
instructions.push(
Token.createAssociatedTokenAccountInstruction(
mintToken.associatedProgramId,
mintToken.programId,
mintPublicKey,
associatedDestinationTokenAddr,
destPublicKey,
wallet.publicKey
)
)
}
instructions.push(
Token.createTransferInstruction(
TOKEN_PROGRAM_ID,
fromTokenAccount.address,
associatedDestinationTokenAddr,
wallet.publicKey,
[],
amount
)
);
const transaction = new web3.Transaction().add(...instructions);
transaction.feePayer = wallet.publicKey;
transaction.recentBlockhash = (await connection.getRecentBlockhash()).blockhash;
const transactionSignature = await connection.sendRawTransaction(
transaction.serialize(),
{ skipPreflight: true }
);
await connection.confirmTransaction(transactionSignature);
}
请注意,如果收件人没有自定义代币账户,我们会添加一条创建该账户的指令。
从下面的导入中可以看出,您需要确保安装了Token程序的npm绑定。
import * as web3 from "@solana/web3.js";
import * as splToken from "@solana/spl-token";

const DEMO_WALLET_SECRET_KEY = new Uint8Array([
37, 21, 197, 185, 105, 201, 212, 148, 164, 108, 251, 159, 174, 252, 43, 246,
225, 156, 38, 203, 99, 42, 244, 73, 252, 143, 34, 239, 15, 222, 217, 91, 132,
167, 105, 60, 17, 211, 120, 243, 197, 99, 113, 34, 76, 127, 190, 18, 91, 246,

]);
(async () => {
// Connect to cluster
var connection = new web3.Connection(web3.clusterApiUrl("devnet"));
// Construct wallet keypairs
var fromWallet = web3.Keypair.fromSecretKey(DEMO_WALLET_SECRET_KEY);
var toWallet = web3.Keypair.generate();
// Construct my token class
var myMint = new web3.PublicKey("My Mint Public Address");
var myToken = new splToken.Token(
connection,
myMint,
splToken.TOKEN_PROGRAM_ID,
fromWallet
);
// Create associated token accounts for my token if they don't exist yet
var fromTokenAccount = await myToken.getOrCreateAssociatedAccountInfo(
fromWallet.publicKey
)
var toTokenAccount = await myToken.getOrCreateAssociatedAccountInfo(
toWallet.publicKey
)
// Add token transfer instructions to transaction
var transaction = new web3.Transaction()
.add(
splToken.Token.createTransferInstruction(
splToken.TOKEN_PROGRAM_ID,
fromTokenAccount.address,
toTokenAccount.address,
fromWallet.publicKey,
[],
0
)
);
// Sign transaction, broadcast, and confirm
var signature = await web3.sendAndConfirmTransaction(
connection,
transaction,
[fromWallet]
);
console.log("SIGNATURE", signature);
console.log("SUCCESS");
})();
publicKey
没有令牌地址时,此解决方案在await myToken.getOrCreateAssociatedAccountInfo(toWallet.publicKey)
上失败。(如果已由Solana修复,请标记。) - MiKK关于@Ozymandias答案的一个小更新,spl-token
库中似乎有一些更改。
首先,Token
不再存在。而一些函数,如Token.getAssociatedTokenAddress
也被删除了。以下是更新后的代码:
import * as splToken from "@solana/spl-token";
import { web3, Wallet } from "@project-serum/anchor";
async function transfer(tokenMintAddress: string, wallet: Wallet, to: string, connection: web3.Connection, amount: number) {
const mintPublicKey = new web3.PublicKey(tokenMintAddress);
const {TOKEN_PROGRAM_ID} = splToken
const fromTokenAccount = await splToken.getOrCreateAssociatedTokenAccount(
connection,
wallet.payer,
mintPublicKey,
wallet.publicKey
);
const destPublicKey = new web3.PublicKey(to);
// Get the derived address of the destination wallet which will hold the custom token
const associatedDestinationTokenAddr = await splToken.getOrCreateAssociatedTokenAccount(
connection,
wallet.payer,
mintPublicKey,
destPublicKey
);
const receiverAccount = await connection.getAccountInfo(associatedDestinationTokenAddr.address);
const instructions: web3.TransactionInstruction[] = [];
instructions.push(
splToken.createTransferInstruction(
fromTokenAccount.address,
associatedDestinationTokenAddr.address,
wallet.publicKey,
amount,
[],
TOKEN_PROGRAM_ID
)
);
const transaction = new web3.Transaction().add(...instructions);
transaction.feePayer = wallet.publicKey;
transaction.recentBlockhash = (await connection.getRecentBlockhash()).blockhash;
const transactionSignature = await connection.sendRawTransaction(
transaction.serialize(),
{ skipPreflight: true }
);
await connection.confirmTransaction(transactionSignature);
}
import { web3, Wallet } from "@project-serum/anchor";
而不是 官方的Solana JS绑定import * as web3 from "@solana/web3.js";
