Solana基础 - 如何查询账户余额

每个 Solana 帐户都需要维持最低数量的原生 SOL 余额（以 lamport 为单位）以将其数据保存在区块链上。

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

const connection = new Connection(clusterApiUrl("devnet"), "confirmed");
const wallet = new PublicKey("nicktrLHhYzLmoVbuZQzHUTicd2sfP571orwo9jfc8c");

const balance = await connection.getBalance(wallet);
console.log(`Balance: ${balance / LAMPORTS_PER_SOL} SOL`);
