## Use Case

DEX swap tracking enables you to:

* Build DEX trading analytics and volume trackers
* Monitor liquidity pool activity
* Analyze trading patterns and arbitrage
* Create real-time price feeds

<Info>Try it yourself with the interactive query interface below:</Info>

<QueryInterfaceSolanaDexSwaps />

## Key Parameters

| Parameter   | Description                                                 |
| ----------- | ----------------------------------------------------------- |
| `programId` | DEX program address (e.g., Orca Whirlpool)                  |
| `d8`        | 8-byte instruction discriminator for swap instruction       |
| `accounts`  | Instruction account addresses (includes pool, tokens, etc.) |
| `data`      | Instruction data payload (contains swap amounts)            |

<Note>
  Different DEX protocols use different instruction discriminators. Check the
  program IDL to find the correct discriminator for your target DEX.
</Note>

## Expected Output

```json theme={"system"}
{
  "header": {
    "number": 259985000,
    "timestamp": 1697544779
  },
  "instructions": [

      "data": "base58encodeddata...",
      "transactionIndex": 0
    }
  ]
}

      }]
  }
  ```
</CodeGroup>

## Decode Swap Amounts

Swap amounts are encoded in the `data` field. Here's how to decode them for Orca Whirlpool:

<Tip>
  Use the Solana typegen tool to generate TypeScript decoders from program IDLs.
  See the [Solana SDK typegen
  documentation](/en/sdk/squid-sdk/solana/reference/solana-typegen) for details.
</Tip>

## Performance Tips

1. **Filter by pool address**: Query specific pools instead of all swaps
2. **Use slot ranges**: Process data in 10k-50k slot batches
3. **Decode off-chain**: Decode swap amounts in your application, not in the query
4. **Combine with token balances**: Use token balances to track actual amounts transferred
