"type": "solana",
"fromBlock": 280000000,
"toBlock": 280000003,
"fields": {
"block": {
"number": true,
"timestamp": true
},
"instruction": {
"programId": true,
"accounts": true,
"data": true,
"transactionIndex": true
}
},
"instructions": [{
"programId": ["whirLbMiicVdio4qvUfM5KAg6Ct8VwpYzGff3uctyCc"],
"d8": ["0xf8c69e91e17587c8"]

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) |
Different DEX protocols use different instruction discriminators. Check the
program IDL to find the correct discriminator for your target DEX.
Expected Output

Track Specific Pool
Monitor swaps for a specific trading pair:
curl --compressed -X POST 'https://portal.sqd.dev/datasets/solana-mainnet/stream' \
-H 'Content-Type: application/json' \
-d '{
"type": "solana",
"fromBlock": 280000000,
"toBlock": 280000003,
"fields": {
"instruction": {
"programId": true,
"accounts": true,
"data": true
}
},
"instructions": [{
"programId": ["whirLbMiicVdio4qvUfM5KAg6Ct8VwpYzGff3uctyCc"],
"d8": ["0xf8c69e91e17587c8"],
"accounts": ["7qbRF6YsyGuLUVs6Y1q64bdVrfe4ZcUUz1JRdoVNUJnm"]
}]
}'
Decode Swap Amounts
Swap amounts are encoded in the data field. Here’s how to decode them for Orca Whirlpool:
- Filter by pool address: Query specific pools instead of all swaps
- Use slot ranges: Process data in 10k-50k slot batches
- Decode off-chain: Decode swap amounts in your application, not in the query
- Combine with token balances: Use token balances to track actual amounts transferred
