Blocks, transactions, TVM event logs, and internal transactions. Tron is the leading network for USDT (TRC-20) settlement; because the TVM is EVM-compatible, TRC-20 events share the same topic signatures as ERC-20.

Quick start

Stream USDT (TRC-20) transfers — the flagship Tron query: 
curl --compressed -X POST \
  'https://portal.sqd.dev/datasets/tron-mainnet/stream' \
  -H 'Content-Type: application/json' \
  -d '{
    "type": "tron",
    "fromBlock": 79257136,
    "toBlock": 79257200,
    "fields": {
      "block": { "number": true, "timestamp": true },
      "log": { "address": true, "topics": true, "data": true }
    },
    "logs": [{
      "address": ["a614f803b6fd780986a42c78ec9c7f77e6ded13c"],
      "topic0": ["ddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef"]
    }]
  }'
Account and contract addresses in filters (owner, to, contract, caller, transferTo) use the native 41-prefixed lowercase hex form. Log addresses and addresses encoded in topics use the 20-byte EVM-style hex form (no 41 prefix). Timestamps are Unix milliseconds; resource and value fields are decimal strings.
