截至2025年6月6日,Solana(SOL)链上的套利机器人主要分为以下5类,涵盖核心策略与关键代码实现(基于最新Solana开发工具包和协议):
geyser-plugin
实时获取待处理交易流。rust
复制
use solana_client::rpc_client::RpcClient;
use solana_sdk::pubkey::Pubkey;
// 监听内存池交易
let rpc = RpcClient::new("https://api.mainnet-beta.solana.com".to_string());
let subscriptions = rpc.geyser_subscribe_pending_transactions().unwrap();
// 识别Raydium Swap交易
if let Some(tx) = subscriptions.recv().unwrap() {
if tx.program_id == ray::ID { // Raydium程序ID
let swap_data = parse_swap_instruction(&tx.data);
if swap_data.amount_in > 1_000_000_000 { // 过滤大额交易
sandwich_attack(&rpc, swap_data).await;
}
}
}
// 夹击交易构建
async fn sandwich_attack(rpc: &RpcClient, target: SwapData) {
let buy_tx = build_swap_tx(target.token_in, target.amount_in * 0.3); // 买入30%
let sell_tx = build_swap_tx(target.token_out, target.amount_out); // 卖出100%
// 设置更高优先级费用
let priority_fee = 10_000; // 10,000 lamports
let buy_sig = rpc.send_transaction_with_priority(&buy_tx, priority_fee).await;
let sell_sig = rpc.send_transaction_with_priority(&sell_tx, priority_fee).await;
}
solana-program-test
模拟交易路径的盈利性。TxBuilder
打包多笔Swap为单笔原子交易。typescript
复制
import { Connection, Keypair } from '@solana/web3.js';
import { findArbitragePaths } from './orca-sdk';
const conn = new Connection("https://api.mainnet-beta.solana.com");
const wallet = Keypair.fromSecretKey(/* 私钥 */);
// 发现套利路径
const paths = await findArbitragePaths(conn, [
"SOL-USDC", "USDC-BTC", "BTC-SOL" // 三角路径
]);
// 构建原子交易
const tx = new Transaction().add(
paths.map(p => {
return createSwapInstruction(
p.pool,
wallet.publicKey,
p.amountIn,
p.minAmountOut
);
})
);
// 设置计算预算(防止交易失败)
tx.add(ComputeBudgetProgram.setComputeUnitLimit({ units: 200_000 }));
tx.sign(wallet);
await conn.sendTransaction(tx);
rust
复制
#[program]
mod flash_arb {
use super::*;
pub fn execute(ctx: Context<FlashArb>, loan_amount: u64) -> Result<()> {
// 1. 从Jet Protocol借款
let jet_accounts = JetAccounts::load(&ctx.accounts)?;
jet::borrow(&jet_accounts, loan_amount)?;
// 2. 执行套利(例如Raydium→Orca价差)
let arb_profit = do_arbitrage(
&ctx.accounts.raydium,
&ctx.accounts.orca,
loan_amount
)?;
// 3. 还款(含利息)
jet::repay(
&jet_accounts,
loan_amount + (loan_amount * 5 / 1000) // 0.5%利息
)?;
Ok(())
}
}
python

for tx in pending_txs:

# 注入流动性

# 监听区块确认后撤资
await wait_for_confirmation(tx.signature)

typescript
复制
import { Helius } from 'helius-sdk';
const helius = new Helius("API_KEY");
const nftListings = await helius.getNFTListings({
marketplaces: ["magic-eden", "tensor"],
priceRange: { max: 1.5 } // 1.5 SOL以下
});

if (listing.price < get_floor_price(listing.collection)) {
const buyTx = await buildBuyTx(listing);
await sendAndConfirmTransaction(buyTx);
// 转卖到Tensor
await listOnTensor(listing.nft, listing.price * 1.3);
}
});
p4d.24xlarge
实例(GPU优化)以降低延迟。注:以上代码需配合最新SDK(如@solana/web3.js 2.0
、anchor-lang 1.0
)使用,测试网验证后再部署主网。
