# PumpSwap program ID, IDL, and swap instructions

> Find the PumpSwap AMM program ID, Anchor IDL, account layouts, and buy/sell instruction examples for Solana developers.

PumpSwap uses a separate AMM program from the Pump.fun bonding curve. Use this reference to identify its program, decode trades, or construct buy/sell instructions from the IDL.

<Info>
  Need swaps without assembling AMM accounts? Use the [Raptor Swap API](/raptor/overview) — it routes graduated Pump.fun tokens through PumpSwap and other DEXes.
</Info>

## Official program IDs

| Program | Address | Role |
| - | - | - |
| **Pump.fun AMM (PumpSwap)** | `pAMMBay6oceH9fJKBRHGP5D4bD4sWpmSwMn52FMfXEA` | Buy/sell, create\_pool, deposit, withdraw |
| **Pump.fun (bonding curve)** | `6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P` | Pre-graduation curve + `migrate` into AMM |
| **Pump Fees** | `pfeeUxB6jkeY1Hxd7CsFCAjcbHA9rWtchMGdZ6VojVZ` | Fee config for buy/sell |

### Well-known accounts

| Account | Notes |
| - | - |
| `global_config` | PDA with seeds `["global_config"]` — commonly `ADyA8hdefvWN2dbGGWFotbzWxrAvLW83WG6QCVXvJKqw` |
| `event_authority` | PDA seeds `["__event_authority"]` on the AMM program |
| `pool` | Per-market pool account (passed into buy/sell) |
| Quote mint (typical) | `So11111111111111111111111111111111111111112` (WSOL) |

After curve completion, the bonding curve program's `migrate` instruction creates the AMM pool.

## Anchor IDL

Use the bundled IDL or compare it with the upstream Pump.fun repository:

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

```javascript theme={null}
import idl from "./idl/pump_amm.json" assert { type: "json" };

console.log(idl.address);
// pAMMBay6oceH9fJKBRHGP5D4bD4sWpmSwMn52FMfXEA
```

## Instruction discriminators

| Instruction | Discriminator (bytes) | Hex |
| - | - | - |
| `buy` | `[102, 6, 61, 18, 1, 218, 235, 234]` | `0x66063d1201daebea` |
| `sell` | `[51, 230, 133, 164, 1, 127, 131, 173]` | `0x33e685a4017f83ad` |
| `buy_exact_quote_in` | `[198, 46, 21, 82, 180, 217, 232, 112]` | `0xc62e1552b4d9e870` |
| `create_pool` | `[233, 146, 209, 142, 207, 104, 64, 188]` | `0xe992d18ecf6840bc` |
| `deposit` | `[242, 35, 198, 137, 82, 225, 242, 182]` | `0xf223c68952e1f2b6` |
| `withdraw` | `[183, 18, 70, 156, 148, 109, 161, 34]` | `0xb712469c946da122` |

<Warning>
  AMM `buy` / `sell` use the **same** Anchor sighashes as bonding-curve `buy` / `sell`. Disambiguate by program ID: `pAMMBay…` (AMM) vs `6EF8rrecth…` (curve).
</Warning>

### Detect amm buy vs sell in Rust

```rust theme={null}
const PUMP_AMM: &str = "pAMMBay6oceH9fJKBRHGP5D4bD4sWpmSwMn52FMfXEA";
const BUY: [u8; 8] = [102, 6, 61, 18, 1, 218, 235, 234];
const SELL: [u8; 8] = [51, 230, 133, 164, 1, 127, 131, 173];

fn is_amm_buy(program_id: &str, data: &[u8]) -> bool {
    program_id == PUMP_AMM && data.get(..8) == Some(&BUY)
}
```

## `buy` instruction

**Args**

| Arg | Type | Meaning |
| - | - | - |
| `base_amount_out` | `u64` | Tokens to receive |
| `max_quote_amount_in` | `u64` | Max quote (e.g. WSOL lamports) to spend |
| `track_volume` | `OptionBool` | `{ 0 }` / `{ 1 }` |

**Accounts**

| # | Account | Writable | Signer |
| - | - | - | - |
| 0 | `pool` | ✓ | |
| 1 | `user` | ✓ | ✓ |
| 2 | `global_config` | | |
| 3 | `base_mint` | | |
| 4 | `quote_mint` | | |
| 5 | `user_base_token_account` | ✓ | |
| 6 | `user_quote_token_account` | ✓ | |
| 7 | `pool_base_token_account` | ✓ | |
| 8 | `pool_quote_token_account` | ✓ | |
| 9 | `protocol_fee_recipient` | | |
| 10 | `protocol_fee_recipient_token_account` | ✓ | |
| 11 | `base_token_program` | | |
| 12 | `quote_token_program` | | |
| 13 | `system_program` | | |
| 14 | `associated_token_program` | | |
| 15 | `event_authority` | | |
| 16 | `program` | | |
| 17 | `coin_creator_vault_ata` | ✓ | |
| 18 | `coin_creator_vault_authority` | | |
| 19 | `global_volume_accumulator` | | |
| 20 | `user_volume_accumulator` | ✓ | |
| 21 | `fee_config` | | |
| 22 | `fee_program` | | |

## `sell` instruction

**Args**

| Arg | Type | Meaning |
| - | - | - |
| `base_amount_in` | `u64` | Tokens to sell |
| `min_quote_amount_out` | `u64` | Min quote out (slippage) |

**Accounts** — same shape as `buy` through `coin_creator_vault_authority` (indices 0–18), then `fee_config` (19) and `fee_program` (20). Sell does **not** pass the volume accumulator accounts.

<Warning>
  Live PumpSwap `buy` instructions often append **remaining accounts** after the 23 IDL accounts (observed +3 on mainnet). `sell` may append +2. Base mints are frequently Token-2022 (`TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb`) while quote is WSOL on the legacy token program. Decode the pool with [/idl/pump\_amm.json](/idl/pump_amm.json) or copy accounts from a recent successful swap before mainnet use.
</Warning>

### Easier path: Raptor + data API

```bash theme={null}
# Find graduated Pump.fun / PumpSwap markets
curl "https://data.solanatracker.io/search?market=pumpfun-amm&limit=20" \
  -H "x-api-key: YOUR_API_KEY"
```

```javascript theme={null}
// Swap a graduated token (Raptor picks PumpSwap / best route)
await fetch("https://swap-v2.solanatracker.io/swap", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    wallet: "YOUR_WALLET_ADDRESS",
    from: "TOKEN_MINT_ADDRESS",
    to: "So11111111111111111111111111111111111111112",
    amount: 1000000,
    slippage: 15,
  }),
});
```
