Solana基础 - 如何按权限获取所有代币账户

 2025-03-19　  Surou　  阅读 　  Solana-优秀转载　  0 评论

您可以按所有者获取代币账户。有两种方法可以做到这一点。

1. 获取所有代币账户

import { clusterApiUrl, Connection, PublicKey } from "@solana/web3.js";
import { TOKEN_PROGRAM_ID } from "@solana/spl-token";

(async () => {
  // connection
  const connection = new Connection(clusterApiUrl("devnet"), "confirmed");

  const owner = new PublicKey("G2FAbFQPFa5qKXCetoFZQEvF9BVvCKbvUZvodpVidnoY");
  let response = await connection.getParsedTokenAccountsByOwner(owner, {
    programId: TOKEN_PROGRAM_ID,
  });

  response.value.forEach(accountInfo => {
    console.log(`pubkey: ${accountInfo.pubkey.toBase58()}`);
    console.log(`mint: ${accountInfo.account.data["parsed"]["info"]["mint"]}`);
    console.log(
      `owner: ${accountInfo.account.data["parsed"]["info"]["owner"]}`,
    );
    console.log(
      `decimals: ${accountInfo.account.data["parsed"]["info"]["tokenAmount"]["decimals"]}`,
    );
    console.log(
      `amount: ${accountInfo.account.data["parsed"]["info"]["tokenAmount"]["amount"]}`,
    );
    console.log("====================");
  });
})();

2. 通过Mint过滤

import { clusterApiUrl, Connection, PublicKey } from "@solana/web3.js";

(async () => {
  // connection
  const connection = new Connection(clusterApiUrl("devnet"), "confirmed");

  const owner = new PublicKey("G2FAbFQPFa5qKXCetoFZQEvF9BVvCKbvUZvodpVidnoY");
  const mint = new PublicKey("54dQ8cfHsW1YfKYpmdVZhWpb9iSi6Pac82Nf7sg3bVb");

  let response = await connection.getParsedTokenAccountsByOwner(owner, {
    mint: mint,
  });

  response.value.forEach(accountInfo => {
    console.log(`pubkey: ${accountInfo.pubkey.toBase58()}`);
    console.log(`mint: ${accountInfo.account.data["parsed"]["info"]["mint"]}`);
    console.log(
      `owner: ${accountInfo.account.data["parsed"]["info"]["owner"]}`,
    );
    console.log(
      `decimals: ${accountInfo.account.data["parsed"]["info"]["tokenAmount"]["decimals"]}`,
    );
    console.log(
      `amount: ${accountInfo.account.data["parsed"]["info"]["tokenAmount"]["amount"]}`,
    );
    console.log("====================");
  });
})();

Solana基础 - 如何使用Wrapped SOL

 2025-03-19　  Surou　  阅读 　  Solana-优秀转载　  0 评论

Wrapped SOL 就像任何其他代币铸币一样。不同之处在于在地址syncNative 上专门使用和创建代币账户NATIVE_MINT。

创建代币账户

类似于创建 SPL 代币账户，但用 minus 替换NATIVE_MINT

import { NATIVE_MINT } from "@solana/spl-token";

添加余额

有两种方式可以为 Wrapped SOL 添加余额

1. 通过 SOL 转移

import {
  clusterApiUrl,
  Connection,
  Keypair,
  Transaction,
  SystemProgram,
  sendAndConfirmTransaction,
} from "@solana/web3.js";
import {
  NATIVE_MINT,
  getAssociatedTokenAddress,
  createSyncNativeInstruction,
} from "@solana/spl-token";
import bs58 from "bs58";

(async () => {
  // connection
  const connection = new Connection(clusterApiUrl("devnet"), "confirmed");

  // 5YNmS1R9nNSCDzb5a7mMJ1dwK9uHeAAF4CmPEwKgVWr8
  const feePayer = Keypair.fromSecretKey(
    bs58.decode(
      "588FU4PktJWfGfxtzpAAXywSNt74AvtroVzGfKkVN1LwRuvHwKGr851uH8czM5qm4iqLbs1kKoMKtMJG4ATR7Ld2",
    ),
  );

  // G2FAbFQPFa5qKXCetoFZQEvF9BVvCKbvUZvodpVidnoY
  const alice = Keypair.fromSecretKey(
    bs58.decode(
      "4NMwxzmYj2uvHuq8xoqhY8RXg63KSVJM1DXkpbmkUY7YQWuoyQgFnnzn6yo3CMnqZasnNPNuAT2TLwQsCaKkUddp",
    ),
  );

  // remember to create ATA first
  let ata = await getAssociatedTokenAddress(
    NATIVE_MINT, // mint
    alice.publicKey, // owner
  );

  let amount = 1 * 1e9; /* Wrapped SOL's decimals is 9 */

  let tx = new Transaction().add(
    // transfer SOL
    SystemProgram.transfer({
      fromPubkey: alice.publicKey,
      toPubkey: ata,
      lamports: amount,
    }),
    // sync wrapped SOL balance
    createSyncNativeInstruction(ata),
  );
  console.log(
    `txhash: ${await sendAndConfirmTransaction(connection, tx, [feePayer, alice])}`,
  );
})();

2. 通过代币转移

import {
  clusterApiUrl,
  Connection,
  Keypair,
  Transaction,
  SystemProgram,
  sendAndConfirmTransaction,
} from "@solana/web3.js";
import {
  TOKEN_PROGRAM_ID,
  NATIVE_MINT,
  getMinimumBalanceForRentExemptAccount,
  getAssociatedTokenAddress,
  ACCOUNT_SIZE,
  createInitializeAccountInstruction,
  createTransferInstruction,
  createCloseAccountInstruction,
} from "@solana/spl-token";
import bs58 from "bs58";

(async () => {
  // connection
  const connection = new Connection(clusterApiUrl("devnet"), "confirmed");

  // 5YNmS1R9nNSCDzb5a7mMJ1dwK9uHeAAF4CmPEwKgVWr8
  const feePayer = Keypair.fromSecretKey(
    bs58.decode(
      "588FU4PktJWfGfxtzpAAXywSNt74AvtroVzGfKkVN1LwRuvHwKGr851uH8czM5qm4iqLbs1kKoMKtMJG4ATR7Ld2",
    ),
  );

  // G2FAbFQPFa5qKXCetoFZQEvF9BVvCKbvUZvodpVidnoY
  const alice = Keypair.fromSecretKey(
    bs58.decode(
      "4NMwxzmYj2uvHuq8xoqhY8RXg63KSVJM1DXkpbmkUY7YQWuoyQgFnnzn6yo3CMnqZasnNPNuAT2TLwQsCaKkUddp",
    ),
  );

  // remember to create ATA first
  let ata = await getAssociatedTokenAddress(
    NATIVE_MINT, // mint
    alice.publicKey, // owner
  );

  let auxAccount = Keypair.generate();
  let amount = 1 * 1e9; /* Wrapped SOL's decimals is 9 */

  let tx = new Transaction().add(
    // create token account
    SystemProgram.createAccount({
      fromPubkey: alice.publicKey,
      newAccountPubkey: auxAccount.publicKey,
      space: ACCOUNT_SIZE,
      lamports:
        (await getMinimumBalanceForRentExemptAccount(connection)) + amount, // rent + amount
      programId: TOKEN_PROGRAM_ID,
    }),
    // init token account
    createInitializeAccountInstruction(
      auxAccount.publicKey,
      NATIVE_MINT,
      alice.publicKey,
    ),
    // transfer WSOL
    createTransferInstruction(
      auxAccount.publicKey,
      ata,
      alice.publicKey,
      amount,
    ),
    // close aux account
    createCloseAccountInstruction(
      auxAccount.publicKey,
      alice.publicKey,
      alice.publicKey,
    ),
  );

  console.log(
    `txhash: ${await sendAndConfirmTransaction(connection, tx, [
      feePayer,
      auxAccount,
      alice,
    ])}`,
  );
})();

你可以设置一个代表你允许的金额，代表就是你token账户的另外一个拥有者。

Solana基础 - 如何设置代币账户或铸币的权限

 2025-03-19　  Surou　  阅读 　  Solana-优秀转载　  0 评论

可以设置/更新权限，一共有4种：

  • MintTokens（铸币账户）
  • FreezeAccount（铸币账户）
  • AccountOwner（代币账户）
  • CloseAccount（代币账户）
import {
  clusterApiUrl,
  Connection,
  PublicKey,
  Keypair,
  Transaction,
  sendAndConfirmTransaction,
} from "@solana/web3.js";
import {
  AuthorityType,
  createSetAuthorityInstruction,
  setAuthority,
} from "@solana/spl-token";
import bs58 from "bs58";

(async () => {
  // connection
  const connection = new Connection(clusterApiUrl("devnet"), "confirmed");

  // 5YNmS1R9nNSCDzb5a7mMJ1dwK9uHeAAF4CmPEwKgVWr8
  const feePayer = Keypair.fromSecretKey(
    bs58.decode(
      "588FU4PktJWfGfxtzpAAXywSNt74AvtroVzGfKkVN1LwRuvHwKGr851uH8czM5qm4iqLbs1kKoMKtMJG4ATR7Ld2",

  const randomGuy = Keypair.generate();
  console.log(`random guy: ${randomGuy.publicKey.toBase58()}`);

  const mintPubkey = new PublicKey(
