Track SPL token transfers to build token analytics, monitor wallet activity, or analyze token flow patterns.

​
Use Case

Token transfer tracking enables you to:
  • Build token transfer analytics and volume trackers
  • Monitor wallet token activity
  • Analyze transfer patterns
  • Track token mints and burns

​
Code Example

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": {
      "block": {
        "number": true,
        "timestamp": true
      },
      "tokenBalance": {
        "account": true,
        "preMint": true,
        "postMint": true,
        "preAmount": true,
        "postAmount": true,
        "preOwner": true,
        "postOwner": true
      }
    },
    "tokenBalances": [{
      "preMint": ["EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"]
    }]
  }'

Expected Output

{
  "header": {
    "number": 259985000,
    "timestamp": 1697544779
  },
  "tokenBalances": [
    {
      "account": "TokenAccountAddress...",
      "preMint": "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v",
      "postMint": "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v",
      "preAmount": "1000000",
      "postAmount": "2000000",
      "preOwner": "SenderAddress...",
      "postOwner": "RecipientAddress..."
    }
  ]
}

Track Specific Token Account

Monitor transfers for a specific token account: 
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": {
      "tokenBalance": {
        "account": true,
        "preAmount": true,
        "postAmount": true
      }
    },
    "tokenBalances": [{
      "account": ["SpecificTokenAccountAddress"]
    }]
  }'

​
Performance Tips

  1. Filter by mint: Query specific tokens instead of all transfers
  2. Use slot ranges: Process data in 10k-50k slot batches
  3. Request minimal fields: Only request fields you need
  4. Filter by account: Monitor specific token accounts
