📦 Installation

npm install @solsdk/relay_sdk

🔨 Quick Start

Replace DEVNET_RPC with your preferred Solana RPC endpoint.

import { Connection, Keypair, PublicKey, LAMPORTS_PER_SOL } from "@solana/web3.js";
import { AnchorProvider, Wallet } from "@coral-xyz/anchor";
import { getAssociatedTokenAddress, getAccount } from "@solana/spl-token";
import { PumpFunSDK, DEFAULT_DECIMALS } from "@solsdk/relay_sdk";

const DEVNET_RPC = "https://api.devnet.solana.com";
const SLIPPAGE_BPS = 100n;
const PRIORITY_FEE = { unitLimit: 250_000, unitPrice: 250_000 };

const secret = JSON.parse(process.env.WALLET!);
const wallet = Keypair.fromSecretKey(Uint8Array.from(secret));

async function printSOL(conn: Connection, pk: PublicKey, label = "") {
  const sol = (await conn.getBalance(pk)) / LAMPORTS_PER_SOL;
  console.log(`${label} SOL:`, sol.toFixed(4));
}

async function getSPLBalance(connection: Connection, mint: PublicKey, owner: PublicKey): Promise<number> {
  try {
    const ata = await getAssociatedTokenAddress(mint, owner);
    const account = await getAccount(connection, ata);
    return Number(account.amount);
  } catch {
    return 0;
  }
}

async function main() {
  const connection = new Connection(DEVNET_RPC, "confirmed");
  const provider = new AnchorProvider(connection, new Wallet(wallet), {
    commitment: "confirmed",
  });
  const sdk = new PumpFunSDK(provider);
  const mint = Keypair.generate();

  await printSOL(connection, wallet.publicKey, "user");

  const img = await import("node:fs/promises").then((fs) =>
    fs.readFile("example/images/test.png")
  );
  const blob = new Blob([img], { type: "image/png" });
  await sdk.trade.createAndBuy(
    wallet,
    mint,
    { name: "DEV-TEST", symbol: "DVT", description: "Devnet demo", file: blob },
    BigInt(0.0001 * LAMPORTS_PER_SOL),
    SLIPPAGE_BPS,
    PRIORITY_FEE
  );
  console.log(
    "Token link →",
    `https://pump.fun/${mint.publicKey}?cluster=devnet`
  );

  await sdk.trade.buy(
    wallet,
    mint.publicKey,
    BigInt(0.0002 * LAMPORTS_PER_SOL),
    SLIPPAGE_BPS,
    PRIORITY_FEE
  );

  const bal = await getSPLBalance(connection, mint.publicKey, wallet.publicKey);
  console.log("Token balance:", bal / 10 ** DEFAULT_DECIMALS);

  await sdk.trade.sell(
    wallet,
    mint.publicKey,
    BigInt(bal),
    SLIPPAGE_BPS,
    PRIORITY_FEE
  );
  await printSOL(connection, wallet.publicKey, "user after sell");
}

main().catch(console.error);

🚀 Advanced Usage

🧠 Buy with Jito

import { PumpFunSDK } from "@solsdk/relay_sdk";

const sdk = new PumpFunSDK(provider, {
  jitoUrl: "ny.mainnet.block-engine.jito.wtf",
  authKeypair: wallet,
});

// Jito tip in lamports (0.0005 SOL)
const jitoTip = 500_000;

await sdk.jito!.buyJito(
  wallet,
  mint.publicKey,
  BigInt(0.0002 * LAMPORTS_PER_SOL),
  SLIPPAGE_BPS,
  jitoTip,
  PRIORITY_FEE,
  "confirmed"
);

💰 Sell with Jito

// Get token balance first
const tokenBalance = await getSPLBalance(connection, mint.publicKey, wallet.publicKey);

await sdk.jito!.sellJito(
  wallet,
  mint.publicKey,
  BigInt(tokenBalance),
  SLIPPAGE_BPS,
  jitoTip,
  PRIORITY_FEE,
  "confirmed"
);

🛰️ Buy with Slot, NodeOne, Astra, or NextBlock

These modules use upstream relayers for ultra-fast transaction submission.
They support periodic ping() to keep HTTPS connections alive and reduce TLS overhead.

import { PumpFunSDK, Region } from "@solsdk/relay_sdk";

const sdk = new PumpFunSDK(provider, {
  providerRegion: Region.Frankfurt,
  slotKey: "your-api-key", // or astraKey / nextBlockKey / nodeOneKey
});

// Keep connection alive
await sdk.slot!.ping();

// Tip in lamports (0.0005 SOL)
const tip = 500_000;

// Buy tokens
const signature = await sdk.slot!.buy(
  wallet,
  mint.publicKey,
  BigInt(0.0002 * LAMPORTS_PER_SOL),
  SLIPPAGE_BPS,
  tip,
  PRIORITY_FEE,
  "confirmed"
);
console.log("Buy transaction:", signature);

💸 Sell with relay modules

// Get token balance
const tokenBalance = await getSPLBalance(connection, mint.publicKey, wallet.publicKey);

// Sell all tokens
const sellSignature = await sdk.slot!.sell(
  wallet,
  mint.publicKey,
  BigInt(tokenBalance),
  SLIPPAGE_BPS,
  tip,
  PRIORITY_FEE,
  "confirmed"
);
console.log("Sell transaction:", sellSignature);

AstraModule, NodeOneModule, and NextBlockModule follow the same interface: buy(), sell(), ping()
Transactions are signed locally and relayed via HTTPS POST (base64-encoded) for speed.

🧩 What Does `ping()` Do?

Relay modules like SlotModule, AstraModule, NodeOneModule, and NextBlockModule implement ping().

Calling ping() periodically:

Prevents connection idle timeouts
Keeps the relay ready for low-latency submission

await sdk.astra!.ping();
await sdk.slot!.ping();

🌐 Supported Relay Regions

Each relay provider supports a set of regions for optimal latency. Below are the currently supported regions per provider:

Slot       📍 Frankfurt • New York • Tokyo • Amsterdam • Los Angeles
Astra      📍 Frankfurt • New York • Tokyo • Amsterdam
NodeOne    📍 New York • Tokyo • Amsterdam • Frankfurt
NextBlock  📍 Tokyo • Frankfurt • New York

🔧 Available Regions
