pumpfun-sdk-core

Minimal, dependency-light building blocks for Pump.fun on Solana.

Features

• Program IDs — Pump, Mayhem, Token-2022 constants
• PDA helpers — Bonding curve, global, mint authority, event authority, Mayhem PDAs
• ATA helpers — Associated token accounts (legacy + Token-2022)
• Instruction builders — create_v2, buy, sell with exact account ordering

Installation

[dependencies]
pumpfun-sdk-core = "0.1"

Usage

Config

use pumpfun_sdk_core::Config;

let cfg = Config::mainnet_create_v2_defaults();
// or Config::devnet_create_v2_defaults() for devnet

Create Token (Token-2022)

use pumpfun_sdk_core::{Config, build_create_v2_ix, CreateV2Params};
use solana_sdk::pubkey::Pubkey;

let cfg = Config::mainnet_create_v2_defaults();
let (ix, accounts) = build_create_v2_ix(
    &cfg,
    CreateV2Params {
        name: "My Coin".to_string(),
        symbol: "COIN".to_string(),
        uri: "https://example.com/metadata.json".to_string(),
        is_mayhem_mode: true,
    },
    mint,
    user,
)?;

Buy / Sell on Bonding Curve

use pumpfun_sdk_core::{Config, build_buy_ix, build_sell_ix, ids};

let (buy_ix, _) = build_buy_ix(
    &cfg,
    mint,
    user,
    fee_recipient,  // fetch via client.fetch_fee_recipient()
    amount,
    max_sol_cost,
    &ids::TOKEN_2022_PROGRAM_ID,
)?;

let (sell_ix, _) = build_sell_ix(
    &cfg,
    mint,
    user,
    fee_recipient,
    amount,
    min_sol_output,
    &ids::TOKEN_2022_PROGRAM_ID,
)?;

PDA Helpers

use pumpfun_sdk_core::pda;
use pumpfun_sdk_core::ids::DEFAULT_PUMP_PROGRAM_ID;

let (bonding_curve, _) = pda::pump_bonding_curve(&DEFAULT_PUMP_PROGRAM_ID, &mint);
let (global, _) = pda::pump_global(&DEFAULT_PUMP_PROGRAM_ID);
let (mint_authority, _) = pda::pump_mint_authority(&DEFAULT_PUMP_PROGRAM_ID);
let (event_authority, _) = pda::pump_event_authority(&DEFAULT_PUMP_PROGRAM_ID);
