pumpfun-sdk-idl

Pump.fun IDL snapshots and generated Anchor-style instruction builders for Rust.

Features

• Pinned IDL — Minimal JSON IDL snapshots for Pump bonding curve and PumpSwap AMM
• Generated types — Rust modules with Accounts, Args, build_ix() per instruction
• Discriminator helpers — Anchor global:<name> discriminator computation
• Embedded IDL — include_str! for IDL JSON at compile time

Installation

IDL Coverage

Usage

Generated instruction builders

use pumpfun_sdk_idl::generated::pump_bonding_curve_min::create_v2;
use pumpfun_sdk_idl::generated::pump_bonding_curve_trade_min::{buy, sell};
use pumpfun_sdk_idl::generated::pump_amm_min::{buy as amm_buy, sell as amm_sell};

Embedded IDL JSON

use pumpfun_sdk_idl::{pump_bonding_curve_min_idl_json, pump_amm_min_idl_json};

let json = pump_bonding_curve_min_idl_json();
// pump_bonding_curve_trade_min_idl_json via pumpfun_sdk_idl::embedded

IDL parsing

use pumpfun_sdk_idl::{Idl, pump_bonding_curve_min_idl_json};

let idl: Idl = serde_json::from_str(pump_bonding_curve_min_idl_json())?;

Regenerating types

When the Pump program IDL changes, regenerate with idl-gen:

cargo run -p idl-gen -- crates/pumpfun-sdk-idl/idl/<idl>.min.json \
  crates/pumpfun-sdk-idl/src/generated/<output>.rs

Dependencies

• serde, serde_json, borsh, sha2, solana-sdk
