pretty_name: BlockDB Liquidity Pools - Sample
size_categories:
- 10M<n<100M
Sample Notice
This dataset contains a small sample of the full BlockDB Liquidity Pools dataset.
It is provided for evaluation, research, and interoperability testing only.
If you need full historical coverage, real-time streaming, or end-of-day (EOD) exports please contact us directly:

Dataset Overview
Canonical list of liquidity pools across all supported DEXes. Each row represents a unique pool with its configuration (exchange, type, tokens, factory) and identifiers (contract address for v2/v3-style pools, pool_id for v4-style pools).
This table serves as the single source of truth for pool identity; child time-series tables (reserves, swaps, yields) reference pools by their pool_uid.
Chains and Coverage
ETH, BSC, Base, Arbitrum, Unichain, Avalanche, Polygon, Celo, Linea, Optimism (others on request). Full history from chain genesis; reorg-aware real-time ingestion and updates.
Schema
List of columns exactly as delivered:
• pool_uid BYTEA – Unique pool identifier derived from address or pool_id (primary key)
• exchange_id INTEGER – Exchange/DEX identifier
• type_id INTEGER – Pool type identifier (FK to liquidity_pool_types)
• block_number BIGINT – Block of the log attributed as the genesis/recognition point
• block_time TIMESTAMPTZ – UTC timestamp when the block was mined
• tx_index INTEGER – Transaction index within the block
• log_index INTEGER – Log index within the block
• factory BYTEA – 20-byte DEX factory/pool-manager address
• tokens BYTEA[] – Array of 20-byte token addresses in the pool
• contract_address BYTEA – 20-byte address for v2/v3-style pools (nullable for id-only v4)
• pool_id BYTEA – 32-byte identifier for v4-style pools (nullable for v2/v3)
• pairnum NUMERIC(6) – Pair number, if applicable
• asset_managers BYTEA[] – Array of asset manager addresses, if applicable
• amp NUMERIC(6) – Amplification parameter for stable pools
• weights NUMERIC(6,5)[] – Token weights (0..1) for weighted pools
• tick_spacing SMALLINT – Tick spacing for concentrated liquidity pools
• _tracing_id BYTEA – Tracing ID of this pool record
• _genesis_tracing_ids BYTEA[] – Tracing IDs of the genesis records leading to this pool record
• _parent_tracing_ids BYTEA[] – Tracing IDs of the parent records leading to this pool record
• _created_at TIMESTAMPTZ – Record creation timestamp
• _updated_at TIMESTAMPTZ – Record last update timestamp
Notes
• At least one of contract_address or pool_id is always populated.
• Indexes on block_number, factory, type_id, (factory, type_id), and tokens (GIN) support fast lookups.
• Binary values can be rendered as hex via encode(column, 'hex') in SQL for display or downstream joins.
Lineage
Each pool record includes deterministic _tracing_id, _genesis_tracing_ids, and _parent_tracing_ids, providing:
• Provenance tracking from raw logs to pool discovery
• Reproducible analytics and signal extraction
• Cross-system consistency checks (RPC vs. indexers vs. internal warehouses)
Common Use Cases
• Building DEX pool registries across multiple protocols
• Pool discovery and new listing detection
• Foundation for swap, reserves, and yield analytics
• Cross-DEX liquidity analysis and comparison
Quality
• Verifiable lineage: deterministic cryptographic hashes per row
• Reorg-aware ingestion: continuity and consistency across forks
• Complete historical coverage: from chain genesis to present
