Pump SDK

TypeScript SDK for the Pump protocol on Solana — token creation, bonding curves, AMM pools, fee sharing, and volume rewards.

What is Pump SDK?

Pump SDK is the community TypeScript SDK for the Pump.fun protocol on Solana. It provides offline-first instruction builders for every on-chain operation — token creation, bonding curve trading, AMM pool management, tiered fee configuration, creator fee sharing, volume-based token incentives, and social referral fees.

The SDK never sends transactions itself. It returns TransactionInstruction[] that you compose into transactions with your preferred signing and sending strategy.

🚀 Quick Start

Installation

# npm
npm install @nirholas/pump-sdk

# yarn
yarn add @nirholas/pump-sdk

# pnpm
pnpm add @nirholas/pump-sdk

Peer Dependencies

The SDK requires these Solana packages (install them if not already present):

npm install @solana/web3.js @solana/spl-token @coral-xyz/anchor bn.js

Minimal Example

import { Connection, PublicKey } from "@solana/web3.js";
import { OnlinePumpSdk } from "@nirholas/pump-sdk";

// 1. Create an online SDK instance
const connection = new Connection("https://api.mainnet-beta.solana.com");
const sdk = new OnlinePumpSdk(connection);

// 2. Fetch current token state
const mint = new PublicKey("YourTokenMintAddress...");
const summary = await sdk.fetchBondingCurveSummary(mint);

console.log("Market Cap:", summary.marketCap.toString(), "lamports");
console.log("Graduated:", summary.isGraduated);
console.log("Progress:", summary.progressBps / 100, "%");

💻 The pump CLI

The SDK ships with a binary. No wallet, no API key, and no configuration are needed for anything that reads the chain.

npm install -g @nirholas/pump-sdk

pump curve <mint>                  # price, market cap, graduation meter, fee tier
pump quote buy <mint> --sol 1      # what 1 SOL really buys, after fees and impact
pump watch <mint>                  # live dashboard
pump doctor                        # check your RPC, wallet, and balance in one shot

Or without installing anything: npx -p @nirholas/pump-sdk pump curve <mint>.

Safe by construction. Reads never load a keypair. Every trade is simulated before anything is sent, prints exactly what is about to happen, and waits for an explicit yes. --simulate sends nothing; --yes is the scripting escape hatch; a piped command with neither refuses rather than spending funds unattended.

Scriptable. Every command takes --json and writes nothing else to stdout in that mode:

pump curve <mint> --json | jq .marketCapSol
pump watch <mint> --json --interval 10 | jq -r '"\(.at)  \(.marketCapSol) SOL"'
pump events <sig> --json | jq '.events[] | select(.type=="trade")'

🧪 50 Runnable Examples

The repo ships fifty tested, runnable examples covering the entire SDK surface. Each one runs with a single command, exports its logic for offline testing, and has a matching step-by-step tutorial.

git clone https://github.com/nirholas/pump-fun-sdk && cd pump-fun-sdk && npm install
npm run example        # list all 50
npm run example 11     # offline buy quotes
npm run test:examples  # run every example's test suite offline

📖 Usage Examples

Create a Token

import { Keypair } from "@solana/web3.js";
import { PUMP_SDK } from "@nirholas/pump-sdk";

const mintKeypair = Keypair.generate();
const creator = wallet.publicKey;

const createIx = await PUMP_SDK.createV2Instruction({
  mint: mintKeypair.publicKey,
  name: "My Token",
  symbol: "MYTKN",
  uri: "https://arweave.net/metadata.json",
  creator,
  user: creator,
  mayhemMode: false,
});

// createIx is a TransactionInstruction — add to a Transaction and send

Warning: Do NOT use createInstruction — it is deprecated (v1). Always use createV2Instruction.

Create a Token With a ...pump Vanity Mint

Mint addresses ending in pump (like the ones on pump.fun) are produced by grinding keypairs off-chain. The SDK exposes this as a first-class helper — swap Keypair.generate() for generateVanityMint() and the rest of the flow is unchanged.

import { generateVanityMint, PUMP_SDK } from "@nirholas/pump-sdk";

// Grind until we find a mint whose address ends in "pump" (~11M attempts, ~1–4 min in Node)
const { keypair: mintKeypair } = await generateVanityMint({ suffix: "pump" });
