# Pump.fun program ID, IDL, and instructions

> Find the Pump.fun bonding curve program ID, Anchor IDL, instruction discriminators, and buy/sell examples for Solana transaction parsers.

Use this reference when building or decoding Pump.fun bonding curve instructions. It covers the program ID, accounts, discriminators, and buy/sell layout. For post-graduation trades, use the PumpSwap program reference.

<Info>
  Prefer not to hand-build instructions? [Raptor Swap API](/raptor/overview) routes buys and sells across Pump.fun bonding curves and PumpSwap automatically.

## Official program IDs

| Program | Address | Role |
| - | - | - |
| **Pump.fun (bonding curve)** | `6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P` | Create tokens, buy/sell on the curve, migrate |
| **Pump.fun AMM (PumpSwap)** | `pAMMBay6oceH9fJKBRHGP5D4bD4sWpmSwMn52FMfXEA` | Post-graduation constant-product pools |
| **Pump Fees** | `pfeeUxB6jkeY1Hxd7CsFCAjcbHA9rWtchMGdZ6VojVZ` | Fee config used by buy/sell |

Copy the program ID exactly. Base58 addresses are case-sensitive; the `r` after `6EF8` is lowercase.

### Well-known pdas

| Account | Seeds | Address |
| - | - | - |
| `global` | `["global"]` | `4wTV1YmiEkRvAtNtsSGPtUrqRYQMe5SKy2uB4Jjaxnjf` |
| `event_authority` | `["__event_authority"]` | PDA of the Pump program |
| `bonding_curve` | `["bonding-curve", mint]` | Per-token curve account |

Solana Tracker market filters: `pumpfun` (bonding curve), `pumpfun-amm` (graduated / PumpSwap).

## Anchor IDL

Download the official Anchor IDL (mirrored from [pump-fun/pump-public-docs](https://github.com/pump-fun/pump-public-docs)):

* **JSON IDL:** [/idl/pump.json](/idl/pump.json)
* Upstream: [idl/pump.json](https://github.com/pump-fun/pump-public-docs/blob/main/idl/pump.json)

```javascript theme={null}
import idl from "./idl/pump.json" assert { type: "json" };
// or: const idl = require("./idl/pump.json");

console.log(idl.address);
// 6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P
```

Load the IDL with Anchor's `Program` or `BorshInstructionCoder`, or use the discriminators below when parsing raw instructions.

## Instruction discriminators

Anchor discriminators are the first **8 bytes** of `sha256("global:<instruction_name>")`. Match these when parsing transactions or building instructions manually.

| Instruction | Discriminator (bytes) | Hex |
| - | - | - |
| `buy` | `[102, 6, 61, 18, 1, 218, 235, 234]` | `0x66063d1201daebea` |
| `sell` | `[51, 230, 133, 164, 1, 127, 131, 173]` | `0x33e685a4017f83ad` |
| `create` | `[24, 30, 200, 40, 5, 28, 7, 119]` | `0x181ec828051c0777` |
| `create_v2` | `[214, 144, 76, 236, 95, 139, 49, 180]` | `0xd6904cec5f8b31b4` |
| `buy_exact_sol_in` | `[56, 252, 116, 8, 158, 223, 205, 95]` | `0x38fc74089edfcd5f` |
| `buy_v2` | `[184, 23, 238, 97, 103, 197, 211, 61]` | `0xb817ee6167c5d33d` |
| `sell_v2` | `[93, 246, 130, 60, 231, 233, 64, 178]` | `0x5df6823ce7e940b2` |
| `migrate` | `[155, 234, 231, 146, 236, 158, 162, 30]` | `0x9beae792ec9ea21e` |

`buy` / `sell` on the **AMM** reuse the same sighashes — always check the **program ID** (`6EF8rrecth…` vs `pAMMBay…`) when classifying trades.

On mainnet, many curve swaps use `buy_exact_sol_in` (`0x38fc74089edfcd5f`) rather than classic `buy`. Parsers should handle both.

### Detect buy vs sell in Rust

```rust theme={null}
const BUY: [u8; 8] = [102, 6, 61, 18, 1, 218, 235, 234];
const SELL: [u8; 8] = [51, 230, 133, 164, 1, 127, 131, 173];
const CREATE: [u8; 8] = [24, 30, 200, 40, 5, 28, 7, 119];

fn classify(data: &[u8]) -> Option<&'static str> {
    let disc = data.get(..8)?;
    if disc == BUY { Some("buy") }
    else if disc == SELL { Some("sell") }
    else if disc == CREATE { Some("create") }
    else { None }
}
```

## `buy` instruction

**Args**

| Arg | Type | Meaning |
| - | - | - |
| `amount` | `u64` | Token amount out (base units) |
| `max_sol_cost` | `u64` | Slippage cap in lamports |
| `track_volume` | `OptionBool` | `{ 0 }` = false, `{ 1 }` = true |

**Accounts**

| # | Account | Writable | Signer |
| - | - | - | - |
| 0 | `global` | | |
| 1 | `fee_recipient` | ✓ | |
| 2 | `mint` | | |
| 3 | `bonding_curve` | ✓ | |
| 4 | `associated_bonding_curve` | ✓ | |
| 5 | `associated_user` | ✓ | |
| 6 | `user` | ✓ | ✓ |
| 7 | `system_program` | | |
| 8 | `token_program` | | |
| 9 | `creator_vault` | ✓ | |
| 10 | `event_authority` | | |
| 11 | `program` | | |
| 12 | `global_volume_accumulator` | | |
| 13 | `user_volume_accumulator` | ✓ | |
| 14 | `fee_config` | | |
| 15 | `fee_program` | | |

Read `fee_recipient` (and the `fee_recipients` array) from the `global` account. Pass `fee_program` = `pfeeUxB6jkeY1Hxd7CsFCAjcbHA9rWtchMGdZ6VojVZ`.

## `sell` instruction

**Args**

| Arg | Type | Meaning |
| - | - | - |
| `amount` | `u64` | Token amount in (base units) |
| `min_sol_output` | `u64` | Slippage floor in lamports |

**Accounts**

| # | Account | Writable | Signer |
| - | - | - | - |
| 0 | `global` | | |
| 1 | `fee_recipient` | ✓ | |
| 2 | `mint` | | |
| 3 | `bonding_curve` | ✓ | |
| 4 | `associated_bonding_curve` | ✓ | |
| 5 | `associated_user` | ✓ | |
| 6 | `user` | ✓ | ✓ |
| 7 | `system_program` | | |
| 8 | `creator_vault` | ✓ | |
| 9 | `token_program` | | |
| 10 | `event_authority` | | |
| 11 | `program` | | |
| 12 | `fee_config` | | |
| 13 | `fee_program` | | |

## `create` instruction

**Args:** `name: string`, `symbol: string`, `uri: string`, `creator: pubkey`\
**Discriminator:** `[24, 30, 200, 40, 5, 28, 7, 119]`

Newer launches often use `create_v2` (Token-2022 / Mayhem / cashback fields). Prefer matching live transactions or the IDL when integrating creation flows.

## Buy / sell with `@solana/web3.js`

Encode the Anchor discriminator, then little-endian `u64` args. `OptionBool` is a single byte (`0` or `1`).

<Warning>
  Live mainnet instructions often append **remaining accounts** after the IDL list (commonly +2 on `buy` / `buy_exact_sol_in` / `sell` for cashback or bonding-curve-v2 flows). Token-2022 mints use `TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb` instead of the legacy token program. Always cross-check a recent successful transaction and the latest [/idl/pump.json](/idl/pump.json) before shipping. For Token-2022 / multi-quote flows, prefer `buy_v2` / `sell_v2` from the IDL.
</Warning>

### Easier path: Raptor swap API

```javascript theme={null}
const res = await fetch("https://swap-v2.solanatracker.io/swap", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    wallet: "YOUR_WALLET_ADDRESS",
    from: "So11111111111111111111111111111111111111112",
    to: "TOKEN_MINT_ADDRESS",
    amount: 0.1,
    slippage: 15,
    priorityFee: 0.0005,
  }),
});
const { txn } = await res.json();
// Sign and send txn
```
