Overview
The Raw Data streams provide push-based access to on-chain execution artifacts as they are finalized. These streams deliver the foundational blockchain primitives that power all derived datasets.Stream Matrix
| Stream | Summary | Dataset ID |
|---|---|---|
| Blocks | Real-time canonical EVM block headers | 0101 |
| Transactions | Executed transactions with gas accounting | 0102 |
| Logs | Decoded event logs with topic filters | 0103 |
| Internal transactions | Call traces | 0111 |
| Contracts | Contract deployment metadata | 0121 |
| Function results | Deterministic contract call outputs | 0122 |
Parameter Conventions
All primitive streams support the following parameters in thesubscribe message:
Chain identifier for the target EVM network. See Chain enumeration for supported values.
Filters
- Blocks: No additional filters.
- Transactions:
from_addresses,to_addresses,status_success. - Logs:
contract_addresses,topic_zeros. - Internal transactions:
from_addresses,to_addresses,call_types. - Contracts:
contract_addresses. - Function results:
contract_addresses,signature_hashes.
Usage Guidance
- Reorg Awareness — Streams handle reorgs by emitting update or delete events when the canonical chain changes.
- Lineage — Each record includes a
_tracing_idto correlate with archive data. - Filtering — Use topic filters for logs to reduce bandwidth for high-volume contracts.
