将SOL从一个钱包发送到另一个钱包永远不会到达

Question

我试图使用system_instructure:：transfer将SOL从Devnet中的一个帐户发送到另一个帐户，但资金从未从wallet_a转移到wallet_b。我是不是错过了什么？钱包A有1.5索拉纳。

我也尝试在发件人中使用私钥，但没有成功。

use solana_sdk::signer::keypair::Keypair;
use solana_client::rpc_client::RpcClient;
use std::{str::FromStr};
use solana_program::{pubkey::Pubkey};
use solana_program::{system_instruction};
fn main () {
let wallet_a = "DVJM5LZEMWwypvgBRysQBUKXE6Jc2wqDcJouGerZnbZz";
let wallet_b = "9c6YTLYHxnRzvQtUwd41qGUBhdSWkGJFtedbxWg8D6eZ";
let from : Pubkey = Pubkey::from_str(&wallet_a).unwrap();
let dest : Pubkey = Pubkey::from_str(&wallet_b).unwrap();
let amount : u64 =  1000000000;
send_sol (&from, &dest, amount);
}
fn send_sol (from_wallet: &Pubkey, to_wallet: &Pubkey, amount: u64) { 
println!("From: {} to: {}", from_wallet, to_wallet);
let result = system_instruction::transfer(from_wallet, to_wallet, amount);
println!("{:?}", result);
}

这是输出：

From: DVJM5LZEMWwypvgBRysQBUKXE6Jc2wqDcJouGerZnbZz to: 9c6YTLYHxnRzvQtUwd41qGUBhdSWkGJFtedbxWg8D6eZ
Instruction { program_id: 11111111111111111111111111111111, accounts: [AccountMeta { pubkey: DVJM5LZEMWwypvgBRysQBUKXE6Jc2wqDcJouGerZnbZz, is_signer: true, is_writable: true }, AccountMeta { pubkey: 9c6YTLYHxnRzvQtUwd41qGUBhdSWkGJFtedbxWg8D6eZ, is_signer: false, is_writable: true }], data: [2, 0, 0, 0, 0, 202, 154, 59, 0, 0, 0, 0] }

因此，您在send_sol函数中所做的一切就是生成发送SOL的指令。您需要将该指令放入Transaction中，然后使用RpcClient:进行签名/发送

let rpc_url = String::from("https://api.devnet.solana.com");
let connection = RpcClient::new_with_commitment(rpc_url, CommitmentConfig::confirmed());
///Airdropping some Sol to the 'from' account
match connection.request_airdrop(&frompubkey, LAMPORTS_PER_SOL) {
Ok(sig) => loop {
if let Ok(confirmed) = connection.confirm_transaction(&sig) {
if confirmed {
println!("Transaction: {} Status: {}", sig, confirmed);
break;
}
}
},
Err(_) => println!("Error requesting airdrop"),
};
///Creating the transfer sol instruction
let ix = system_instruction::transfer(&frompubkey, &topubkey, lamports_to_send);
///Putting the transfer sol instruction into a transaction
let recent_blockhash = connection.get_latest_blockhash().expect("Failed to get latest blockhash.");
let txn = Transaction::new_signed_with_payer(&[ix], Some(&frompubkey), &[&from], recent_blockhash);
///Sending the transfer sol transaction
match connection.send_and_confirm_transaction(&txn){
Ok(sig) => loop {
if let Ok(confirmed) = connection.confirm_transaction(&sig) {
if confirmed {
println!("Transaction: {} Status: {}", sig, confirmed);
break;
}
}
},
Err(e) => println!("Error transferring Sol:, {}", e),
}
