如何使用Solana的web3.js-sdk传输SOL？

Answer 1

var web3 = require("@solana/web3.js");
// Address: 9vpsmXhZYMpvhCKiVoX5U8b1iKpfwJaFpPEEXF7hRm9N
const DEMO_FROM_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,
121, 93, 189, 55, 165, 129, 196, 104, 25, 157, 209, 168, 165, 149,
]);
(async () => {
// Connect to cluster
var connection = new web3.Connection(web3.clusterApiUrl("devnet"));
// Construct a `Keypair` from secret key
var from = web3.Keypair.fromSecretKey(DEMO_FROM_SECRET_KEY);
// Generate a new random public key
var to = web3.Keypair.generate();
// Add transfer instruction to transaction
var transaction = new web3.Transaction().add(
web3.SystemProgram.transfer({
fromPubkey: from.publicKey,
toPubkey: to.publicKey,
lamports: web3.LAMPORTS_PER_SOL / 100,
})
);
// Sign transaction, broadcast, and confirm
var signature = await web3.sendAndConfirmTransaction(
connection,
transaction,
[from]
);
console.log("SIGNATURE", signature);
console.log("SUCCESS");
})();

下面是一个如何做到这一点的示例。假设：

1. 你有一个幻影钱包
2. 你正在开发devnet
3. 您有一个目标钱包的公钥(地址(字符串。这里将使用CCD_ 1

代码

import * as web3 from '@solana/web3.js';
import * as splToken from '@solana/spl-token';

const getProvider = async () => {
if ("solana" in window) {
const provider = window.solana;
if (provider.isPhantom) {
console.log("Is Phantom installed?  ", provider.isPhantom);
return provider;
}
} else {
window.open("https://www.phantom.app/", "_blank");
}
};

async function transferSOL() {
// Detecing and storing the phantom wallet of the user (creator in this case)
var provider = await getProvider();
console.log("Public key of the emitter: ",provider.publicKey.toString());
// Establishing connection
var connection = new web3.Connection(
web3.clusterApiUrl('devnet'),
);
// I have hardcoded my secondary wallet address here. You can take this address either from user input or your DB or wherever
var recieverWallet = new web3.PublicKey("9fuYBoRvgptU4fVZ8ZqvWTTc6oC68P4tjuSA2ySzn6Nv");
// Airdrop some SOL to the sender's wallet, so that it can handle the txn fee
var airdropSignature = await connection.requestAirdrop(
provider.publicKey,
web3.LAMPORTS_PER_SOL,
);
// Confirming that the airdrop went through
await connection.confirmTransaction(airdropSignature);
console.log("Airdropped");
var transaction = new web3.Transaction().add(
web3.SystemProgram.transfer({
fromPubkey: provider.publicKey,
toPubkey: recieverWallet,
lamports: web3.LAMPORTS_PER_SOL //Investing 1 SOL. Remember 1 Lamport = 10^-9 SOL.
}),
);
// Setting the variables for the transaction
transaction.feePayer = await provider.publicKey;
let blockhashObj = await connection.getRecentBlockhash();
transaction.recentBlockhash = await blockhashObj.blockhash;
// Transaction constructor initialized successfully
if(transaction) {
console.log("Txn created successfully");
}

// Request creator to sign the transaction (allow the transaction)
let signed = await provider.signTransaction(transaction);
// The signature is generated
let signature = await connection.sendRawTransaction(signed.serialize());
// Confirm whether the transaction went through or not
await connection.confirmTransaction(signature);
//Print the signature here
console.log("Signature: ", signature);
}
