Raw Data Streams Overview

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 the subscribe message:

chain_id

number

required

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_id to correlate with archive data.
Filtering — Use topic filters for logs to reduce bandwidth for high-volume contracts.
