要发送 SOL，您需要与 SystemProgram进行交互。

gill

import {
  address,
  lamports,
  createTransaction,
  createSolanaClient,
  signTransactionMessageWithSigners,
} from "gill";
import { loadKeypairSignerFromFile } from "gill/node";
import { getTransferSolInstruction } from "gill/programs";

const { rpc, sendAndConfirmTransaction } = createSolanaClient({
  urlOrMoniker: "devnet",
});

// loads Signer from the default Solana CLI keypair path: `~/.config/solana/id.json`
const signer = await loadKeypairSignerFromFile();

const destination = address("nick6zJc6HpW3kfBm4xS2dmbuVRyb5F3AnUvj5ymzR5");

const { value: latestBlockhash } = await rpc.getLatestBlockhash().send();

const tx = createTransaction({
  version: "legacy",
  feePayer: signer,
  instructions: [
    getTransferSolInstruction({
      source: signer,
      destination,
      amount: lamports(1_000_000n),
    }),
  ],
  latestBlockhash,
});

const signedTransaction = await signTransactionMessageWithSigners(tx);
await sendAndConfirmTransaction(signedTransaction);

web3.js

import {
  Connection,
  Keypair,
  SystemProgram,
  LAMPORTS_PER_SOL,
  Transaction,
  sendAndConfirmTransaction,
} from "@solana/web3.js";

const fromKeypair = Keypair.generate();
const toKeypair = Keypair.generate();

const connection = new Connection("https://api.devnet.solana.com", "confirmed");

const airdropSignature = await connection.requestAirdrop(
  fromKeypair.publicKey,
  LAMPORTS_PER_SOL,
);

await connection.confirmTransaction(airdropSignature);

const lamportsToSend = 1_000_000;

const transferTransaction = new Transaction().add(
  SystemProgram.transfer({
    fromPubkey: fromKeypair.publicKey,
    toPubkey: toKeypair.publicKey,
    lamports: lamportsToSend,
  }),
);

await sendAndConfirmTransaction(connection, transferTransaction, [fromKeypair]);
