Pump SDK

Official Pump program SDK

const connection = new Connection(
    "https://api.devnet.solana.com",
    "confirmed",
);
const sdk = new PumpSdk(connection);

Coin creation

const mint = PublicKey.unique();
const creator = PublicKey.unique();
const user = PublicKey.unique();

const instruction = await sdk.createInstruction({
    mint,
    name: "name",
    symbol: "symbol",
    uri: "uri",
    creator,
    user,
});

// or creating and buying instructions in the same tx

const global = await sdk.fetchGlobal();
const solAmount = new BN(0.1 * 10 ** 9); // 0.1 SOL

const instructions = await sdk.createAndBuyInstructions({
    global,
    mint,
    name: "name",
    symbol: "symbol",
    uri: "uri",
    creator,
    user,
    solAmount,
    amount: getBuyTokenAmountFromSolAmount(global, null, solAmount),
});

Buying coins

const mint = PublicKey.unique();
const user = PublicKey.unique();

const global = await sdk.fetchGlobal();
const { bondingCurveAccountInfo, bondingCurve, associatedUserAccountInfo } =
    await sdk.fetchBuyState(mint, user);
const solAmount = new BN(0.1 * 10 ** 9); // 0.1 SOL

const instructions = await sdk.buyInstructions({
    global,
    bondingCurveAccountInfo,
    bondingCurve,
    associatedUserAccountInfo,
    mint,
    user,
    solAmount,
    amount: getBuyTokenAmountFromSolAmount(global, bondingCurve, solAmount),
    slippage: 1,
});

Selling coins

const mint = PublicKey.unique();
const user = PublicKey.unique();

const global = await sdk.fetchGlobal();
const { bondingCurveAccountInfo, bondingCurve } = await sdk.fetchSellState(mint, user);
const amount = new BN(15_828);

const instructions = await sdk.sellInstructions({
    global,
    bondingCurveAccountInfo,
    bondingCurve,
    mint,
    user,
    amount,
    solAmount: getSellSolAmountFromTokenAmount(global, bondingCurve, amount),
    slippage: 1,
});

Creator fees

const user = PublicKey.unique();

// Getting total accumulated creator fees for both Pump and PumpSwap programs
console.log((await sdk.getCreatorVaultBalanceBothPrograms(user)).toString());

// Collecting creator fees instructions
const instructions = await sdk.collectCoinCreatorFeeInstructions(user);
