Pump.fun Program ID, Instructions and Error Codes

Program IDs

Instruction discriminators

Each Anchor instruction starts with an 8-byte discriminator: the first 8 bytes of sha256("global:<name>").

Pump (bonding curve)

PumpSwap

Buy: accounts in order

Arguments: amount, max_sol_cost, track_volume, partial_fill. W = writable, S = signer. Accounts must be passed in exactly this order.

Sell: accounts in order

Arguments: amount, min_sol_output. Note that in sell, creator_vault comes before token_program, the opposite of buy.

Deriving the main PDAs

import { PublicKey } from "@solana/web3.js";
const PUMP = new PublicKey("6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P");
const pda = (...seeds: (Buffer | Uint8Array)[]) => PublicKey.findProgramAddressSync(seeds, PUMP)[0];

const global       = pda(Buffer.from("global"));
const bondingCurve = pda(Buffer.from("bonding-curve"), mint.toBuffer());
const creatorVault = pda(Buffer.from("creator-vault"), creator.toBuffer()); // creator from the BondingCurve account
const eventAuth    = pda(Buffer.from("__event_authority"));
const globalVolume = pda(Buffer.from("global_volume_accumulator"));
const userVolume   = pda(Buffer.from("user_volume_accumulator"), user.toBuffer());

associated_bonding_curve is the bonding curve's associated token account for the mint. fee_config is a PDA of the fees program; take it from the IDL or the SDK rather than hard-coding it.

Common errors and fixes

6005's message still says "migrated to raydium": graduated coins now go to PumpSwap. Transaction stuck or failing for other reasons? See Pump.fun transaction stuck.

All Pump program error codes

Anchor custom errors start at 6000 (0x1770). If your error is a hex number, find it in the Hex column.
