买卖 Pump 平台代币风险极大，请对自己的钱包负责！

Pump 作为 Solana 的发币平台，每天有大量的新流动池被创建，本文提供了一个 demo，教你如何狙击 pump 上的新流动池。主要内容包括：① 基于 geyser grpc 监听 pump 新流动池创建；② 获取买入和卖出新流动池代币所需要的账户；③ 基于 Jito 上链的买入；④ 卖出

用到的库

import "dotenv/config";
import Client, {CommitmentLevel, SubscribeRequest} from '@triton-one/yellowstone-grpc';
import bs58 from "bs58";
import {Connection, PublicKey, Transaction, SystemProgram} from "@solana/web3.js";
import {AnchorProvider, Program, Wallet} from "@coral-xyz/anchor";
import {getKeypairFromEnvironment} from "@solana-developers/helpers";
import fs from "fs";
import {createAssociatedTokenAccountInstruction, getAssociatedTokenAddress} from "@solana/spl-token";
import { BN } from "bn.js";
import axios from "axios";

监听 pump 新流动池创建

为了保证获取链上数据的速度，本部分采用 geyser grpc 订阅的方法获取链上数据。

以下为订阅 pump 新池子的代码，主要步骤为：

创建 grpc 订阅的客户端
订阅交易中包含 pump 账户（6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P）的交易
判断日志中是否有 InitializeMint2 方法
打印一些新池子账户，包括代币 Mint 账户，Bonding Curve 账户和 Associated Bonding Curve 账户，都是后面买入操作需要的

const client = new Client('https://grpc.chainbuff.com', undefined, {
    "grpc.max_receive_message_length": 64 * 1024 * 1024, // 64MiB
});

const stream = await client.subscribe();

const streamClosed = new Promise<void>((resolve, reject) => {
    stream.on("error", (error) => {
        reject(error);
        stream.end();
    });
    stream.on("end", () => {
        resolve();
    });
    stream.on("close", () => {
        resolve();
    });
});

stream.on("data", async (data) => {

    if (data.transaction && data.transaction.transaction.meta.logMessages && data.transaction.transaction.meta.logMessages.some(log => log.includes("Program log: Instruction: InitializeMint2"))) {

        console.log('slot:', data.transaction.slot);
        const accountKeys = data.transaction.transaction.transaction.message.accountKeys.map(ak => bs58.encode(ak));
        console.log('Transaction signature:', bs58.encode(data.transaction.transaction.signature));
        console.log('Mint:', accountKeys[1]);
        console.log('Bonding Curve:', accountKeys[3]);
        console.log('Associated Bonding Curve:', accountKeys[4]);
        console.log('---\n')
    }
});

const request = {
    accounts: {},
    slots: {},
    transactions: {},
    blocks: {},
    blocksMeta: {},
    entry: {},
    commitment: CommitmentLevel.CONFIRMED,
    accountsDataSlice: [],
    ping: undefined,
};
request.transactions.tx = {
    vote: false,
    failed: false,
    signature: undefined,
    accountInclude: ["6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P"], // pump
    accountExclude: [],
    accountRequired: [],
};

await new Promise<void>((resolve, reject) => {
    stream.write(request, (err) => {
        if (err === null || err === undefined) {
            resolve();
        } else {
            reject(err);
        }
    });
}).catch((reason) => {
    console.error(reason);
    throw reason;
});

await streamClosed;

输出应如下：

买入

买入操作需要与 pump 合约交互，首先我们需要 pump 合约的的 idl 文件，在此获取：https://chainbuff.com/d/11

观察一笔 pump 的买入交易会发现，在调用 pump 合约的买入指令时，

输入账户 1，2，8，9，10，11，12 是固定的；3，4，5 从刚才监听到的新池子创建交易中已经获取到；6 和 7 分别是 ATA 和我们的买入账户
指令参数分别是买入的代币数量和最大的 sol 花费

因此，买入的交易可以按照下面的方法组装

创建交易
添加 ATA 创建指令
添加 pump 买入指令

const payer = getKeypairFromEnvironment("PUMP_SECRET_KEY"); // 钱包私钥从本地.env文件中获取
console.log(payer.publicKey.toBase58())
const connection = new Connection('http://127.0.0.1:8899', 'confirmed');
const wallet = new Wallet(payer);
const provider = new AnchorProvider(connection, wallet, {
    commitment: 'confirmed',
});
const pumpIDL = JSON.parse(fs.readFileSync('./pump_idl.json', 'utf8')); // 此处需要IDL文件
const pumpProgramId = new PublicKey('6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P');
const pumpProgram = new Program(pumpIDL, pumpProgramId, provider);

// 创建交易
let transaction = new Transaction();

// 添加ATA创建指令
transaction.add(
    createAssociatedTokenAccountInstruction(
        payer.publicKey,
        associatedUser,
        payer.publicKey,
        new PublicKey(accountKeys[1]),
    )
)

// 获取ATA
const associatedUser = await getAssociatedTokenAddress(new PublicKey(accountKeys[1]), payer.publicKey, false);

// 添加pump买入指令
const amount = 17231 * 1e6;
const solAmount = 0.001 * 1e9;
transaction.add(
    await pumpProgram.methods
        .buy(new BN(amount.toString()), new BN(solAmount.toString()))
        .accounts({
            global: new PublicKey('4wTV1YmiEkRvAtNtsSGPtUrqRYQMe5SKy2uB4Jjaxnjf'),
            feeRecipient: new PublicKey('CebN5WGQ4jvEPvsVU4EoHEpgzq1VV7AbicfhtW4xC9iM'),
            mint: new PublicKey(accountKeys[1]),
            bondingCurve: new PublicKey(accountKeys[3]),
            associatedBondingCurve: new PublicKey(accountKeys[4]),
            associatedUser: associatedUser,
            user: payer.publicKey,
            systemProgram: new PublicKey('11111111111111111111111111111111'),
            tokenProgram: new PublicKey('TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA'),
            rent: new PublicKey('SysvarRent111111111111111111111111111111111'),
            eventAuthority: new PublicKey('Ce6TQqeHC9p8KetsN6JsjHK7UTZk7nasjjnr7XxXp9F1'),
            program: new PublicKey('6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P')
        })
        .instruction()
);

至此，pump 新池子买入交易的组装其实就已经完成，通过对交易进行签名后，就可以正常发送。

此处可以在自己的 rpc 上模拟一下交易指令是否组装正确

const { blockhash } = await connection.getLatestBlockhash();
transaction.recentBlockhash = blockhash;
transaction.feePayer = payer.publicKey;

const signedTransaction = await wallet.signTransaction(transaction);

// simulate
const simulationResult = await connection.simulateTransaction(signedTransaction);
console.log(JSON.stringify(simulationResult));

输出如下，没有报错

Jito 发送交易

使用 Jito 上链只需要①在交易的最后添加一笔给 jito tip 账户转账的指令，用于支付小费；②将交易发给 Jito 的 block engine

具体代码如下

// 添加支付小费指令
transaction.add(SystemProgram.transfer({
    fromPubkey: wallet.publicKey,
    toPubkey: new PublicKey('DttWaMuVvTiduZRnguLF7jNxTgiMBZ1hyAumKUiL2KRL'),
    lamports: 0.001*1e9,
}))

const { blockhash } = await connection.getLatestBlockhash();
transaction.recentBlockhash = blockhash;
transaction.feePayer = payer.publicKey;

const signedTransaction = await wallet.signTransaction(transaction);

// 发送交易
const serializedTransaction = signedTransaction.serialize();
const base58Transaction = bs58.encode(serializedTransaction);

const bundle_data = {
    jsonrpc: "2.0",
    id: 1,
    method: "sendBundle",
    params: [[base58Transaction]]
};
const bundle_resp = await axios.post(`https://frankfurt.mainnet.block-engine.jito.wtf/api/v1/bundles`, bundle_data, {
    headers: {
        'Content-Type': 'application/json'
    }
});
const bundle_id = bundle_resp.data.result
console.log(`sent to frankfurt, bundle id: ${bundle_id}`)

卖出

观察一笔卖出的交易指令会发现，输入账户与买入相同，指令参数变为了卖出的代币数量和获得的最少 sol 数量。可参照之前的买入操作写自己的卖出策略。

卖出策略因人而异，不仅要保证自己获取链上数据的速度和上链的速度，要买的快，还要卖的好。但要问我哪个更重要，我想说，买的快不如卖的好。

最后，geyser grpc 订阅服务对于个人来说比较昂贵，可联系我获取社区节点的 geyser 服务，限制使用人数，无频率限制。
