## What is Pump SDK?

Pump SDK is the community TypeScript SDK for the [Pump.fun](https://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

```bash
# 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):

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

### Minimal Example

```typescript
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.

```bash
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>`.

```
FeMbDoX7R1Psc4GEcvJdsbNbZA3bfztcyDCatJVJpump live on the bonding curve
────────────────────────────────────────────────────────────

  Market cap   93.705347 SOL

```

| Command | What it does |
|---|---|
| `pump curve` / `price` / `pool` / `global` | Read curve, price, AMM pool, and protocol state |
| `pump quote buy\|sell` | Price a trade offline: output, fees, effective price, impact |
| `pump buy` / `sell` | Trade, auto-routing between the bonding curve and PumpAMM |
| `pump create` | Launch a token, optionally with an atomic first buy |
| `pump vanity` | Grind a `...pump` mint address |
| `pump fees` / `incentives` | Check and claim creator fees and volume rewards |
| `pump watch` | Live-refreshing dashboard, or a JSON price feed |
| `pump events` | Decode the Pump events in any transaction |
| `pump pda` | Derive any Pump program address |
| `pump doctor` / `config` | Diagnose and configure |

**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:

```bash
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

```typescript
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.

```typescript
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/`](rust/). See
[Tutorial 13: Vanity Mints](tutorials/13-vanity-addresses.md) for the full
end-to-end flow and a runnable devnet example.

### Buy Tokens on the Bonding Curve

```typescript
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

```typescript
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

```typescript
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

```typescript
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.

| `NoShareholdersError` | Empty shareholders array | Provide at least 1 shareholder |
| `TooManyShareholdersError` | More than 10 shareholders | Reduce to ≤ 10 shareholders |
| `ZeroShareError` | A shareholder has 0 or negative BPS | Set all shares to positive values |
| `InvalidShareTotalError` | Shares don't sum to 10,000 BPS | Ensure shares total exactly 10,000 |
| `DuplicateShareholderError` | Same address appears twice | Remove duplicate addresses |
| `ShareCalculationOverflowError` | BPS sum exceeds safe integer range | Check share values |
| `PoolRequiredForGraduatedError` | `pool` is null for a graduated coin | Pass the pool address from `fetchPool()` |

### 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.
