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")'

📖 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 Holder-Reward Token

Set holderReward: true to direct creator fees to the protocol-derived holder rewards PDA. Pump.fun distributes those fees to holders automatically; holders do not need to submit claims.

const createIx = await PUMP_SDK.createV2Instruction({
  mint: mintKeypair.publicKey,
  name: "Holder Helper",
  symbol: "HOLD",
  uri: "https://example.com/holder-helper.json",
  creator: wallet.publicKey,
  user: wallet.publicKey,
  mayhemMode: false,
  holderReward: true,
});

For an atomic launch and initial buy, pass the same flag to createV2AndBuyInstructions; the SDK routes the buy through creatorVaultPda(holderRewardsPda(mint)). Run the complete broadcast-free demo with npm run example 51.

New cashback launches are deprecated and rejected. Existing cashback coins remain tradeable and accrued cashback remains claimable.

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" });

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

// Sign the transaction with BOTH the payer and the mint keypair.
// tx.sign([wallet, mintKeypair]);

Supports prefix, suffix, caseInsensitive, maxAttempts, onProgress, and AbortSignal. For patterns longer than 4 characters, use the multi-threaded Rust generator at rust/. See Tutorial 13: Vanity Mints for the full end-to-end flow and a runnable devnet example.

Buy Tokens on the Bonding Curve

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

const connection = new Connection("https://api.mainnet-beta.solana.com");
const sdk = new OnlinePumpSdk(connection);

const mint = new PublicKey("TokenMintAddress...");
const user = wallet.publicKey;

// Fetch all required state in parallel — buyState includes tokenProgram (auto-detected)
const [buyState, global, feeConfig] = await Promise.all([
  sdk.fetchBuyState(mint, user),
  sdk.fetchGlobal(),
  sdk.fetchFeeConfig(),
]);

assert(!buyState.bondingCurve.complete, "Token has already graduated to AMM");

// Calculate expected tokens for 0.1 SOL
const solAmount = new BN(100_000_000); // 0.1 SOL in lamports
const expectedTokens = getBuyTokenAmountFromSolAmount({
  global,
  feeConfig,
  mintSupply: buyState.bondingCurve.tokenTotalSupply,
  bondingCurve: buyState.bondingCurve,
  amount: solAmount,
});

// buyState spreads: bondingCurveAccountInfo, bondingCurve, associatedUserAccountInfo, tokenProgram
const buyIxs = await sdk.buyInstructions({
  ...buyState,
  mint,
  user,
  amount: expectedTokens,
  solAmount,
  slippage: 0.05,         // 5% slippage tolerance
});
// buyIxs is TransactionInstruction[] — compose into a VersionedTransaction and send

Note: fetchBuyState auto-detects whether the token uses SPL Token or Token-2022 and returns tokenProgram accordingly. Always spread ...buyState into buyInstructions to ensure the correct program is used.

Sell Tokens

import BN from "bn.js";
import { getSellSolAmountFromTokenAmount, OnlinePumpSdk } from "@nirholas/pump-sdk";

const sdk = new OnlinePumpSdk(connection);

// Fetch required state in parallel
// Pass buyState.tokenProgram if you have it to avoid a second mint account fetch
const [sellState, global, feeConfig] = await Promise.all([
  sdk.fetchSellState(mint, user),
  sdk.fetchGlobal(),
  sdk.fetchFeeConfig(),
]);

const tokenAmount = new BN(1_000_000_000); // amount in raw units (6 decimals)
const expectedSol = getSellSolAmountFromTokenAmount({
  global,
  feeConfig,
  mintSupply: sellState.bondingCurve.tokenTotalSupply,
  bondingCurve: sellState.bondingCurve,
  amount: tokenAmount,
});

// sellState spreads: bondingCurveAccountInfo, bondingCurve, tokenProgram
const sellIxs = await sdk.sellInstructions({
  ...sellState,
  mint,
  user,
  amount: tokenAmount,
  solAmount: expectedSol,
  slippage: 0.05,
});

Note: fetchSellState returns tokenProgram (auto-detected from the mint). Always spread ...sellState into sellInstructions.

Check Graduation Progress

import { OnlinePumpSdk } from "@nirholas/pump-sdk";

const sdk = new OnlinePumpSdk(connection);
const progress = await sdk.fetchGraduationProgress(mint);

console.log(`Progress: ${progress.progressBps / 100}%`);
console.log(`Graduated: ${progress.isGraduated}`);
console.log(`Tokens remaining: ${progress.tokensRemaining.toString()}`);
console.log(`SOL accumulated: ${progress.solAccumulated.toString()}`);

Set Up Fee Sharing

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

// Create a fee sharing config (creator only, before or after graduation)
const createConfigIx = await PUMP_SDK.createFeeSharingConfig({
  creator: wallet.publicKey,
  mint: tokenMint,
  pool: null,  // null for pre-graduation tokens
});

// Update shareholders (must total exactly 10,000 BPS = 100%)
const updateIx = await PUMP_SDK.updateFeeShares({
  authority: wallet.publicKey,
  mint: tokenMint,
  currentShareholders: [wallet.publicKey],
  newShareholders: [
    { address: wallet.publicKey, shareBps: 7000 },         // 70%
    { address: new PublicKey("Partner..."), shareBps: 3000 }, // 30%
  ],
});

Warning: Shares must total exactly 10,000 BPS. The SDK throws InvalidShareTotalError otherwise. Maximum 10 shareholders.

⚠️ Error Handling

The SDK defines typed errors for fee sharing validation:

Common Pitfalls

Warning: Never use JavaScript number for token or lamport amounts. Always use BN from bn.js. JavaScript numbers lose precision above 2^53.

Warning: Check bondingCurve.complete before trading. If true, the token has graduated to AMM — use ammBuyInstruction/ammSellInstruction instead.

Warning: createInstruction is deprecated. Use createV2Instruction for all new token creation.

❓ FAQ

Q: Do I need an RPC connection to use the SDK? No. PumpSdk (and the PUMP_SDK singleton) builds instructions offline. Only use OnlinePumpSdk when you need to fetch on-chain state.

Q: How do I know if a token has graduated to AMM? Check bondingCurve.complete === true or use sdk.isGraduated(mint). Graduated tokens trade on PumpAMM, not the bonding curve.

Q: What is slippage in buy/sell instructions? A decimal fraction (e.g., 0.05 = 5%). The SDK adjusts maxSolCost (buy) or minSolOutput (sell) to protect against price movement.

Q: Why do amounts use BN instead of number? Solana token amounts (lamports, token units) regularly exceed JavaScript's safe integer limit (2^53). BN provides arbitrary-precision arithmetic.

Q: What's the difference between Pump and PumpAMM programs? Pump handles the bonding curve phase (creation → graduation). PumpAMM handles post-graduation trading with constant-product AMM pools.

Q: How does fee sharing work? Token creators can split their creator fees among up to 10 shareholders. Each shareholder gets a share in basis points (1/10,000). The total must equal exactly 10,000 BPS (100%).

Q: What is Mayhem Mode? A special token creation mode with randomized bonding curve parameters. Tokens created with mayhemMode: true have unpredictable pricing dynamics.

Q: Can I use the SDK in the browser? Yes. The SDK has no Node.js-specific dependencies. The ESM build works in modern browsers with a bundler.
