## Sample Notice |
|
|
|
|
|
This dataset contains **a small sample** of the full BlockDB Liquidity Pools Reserves 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 |

## Dataset Overview |
|
|
Time-series of pool reserve/state snapshots across all AMM types. Each row represents a snapshot of pool state at a specific on-chain event, including reserves for constant-product pools and tick/bin data for concentrated liquidity pools (Uniswap v3/v4, Algebra, TraderJoe bins, etc.). |
|
|
|
|
|
|
|
|
## 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: |
|
|
|
|
|
• id BIGINT – Unique snapshot identifier (primary key) |
|
|
• pool_uid BYTEA – Unique pool identifier (FK to liquidity_pools) |
|
|
• exchange_id INTEGER – Exchange/DEX identifier |
|
|
• type_id INTEGER – Pool type identifier (FK to liquidity_pool_types) |
|
|
• block_number BIGINT – Block when this state was observed |
|
|
• 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 |
|
|
• reserves NUMERIC(78,0)[] – Array of current reserves per token for even-style pools (raw units) |
|
|
• current_tick INTEGER – Current tick for concentrated-liquidity pools (e.g., Uniswap v3) |
|
|
• current_sqrt_price NUMERIC(49,0) – Q64.96 sqrt price as integer; decode via (value / 2^96)^2 for mid-price |
|
|
• current_bin INTEGER – Current bin id for bin-based AMMs (e.g., TraderJoe v2) |
|
|
• _tracing_id BYTEA – Tracing ID of this reserves record |
|
|
• _genesis_tracing_ids BYTEA[] – Tracing IDs of the genesis records leading to this record |
|
|
• _parent_tracing_ids BYTEA[] – Tracing IDs of the parent records leading to this record |
|
|
• _created_at TIMESTAMPTZ – Record creation timestamp |
|
|
• _updated_at TIMESTAMPTZ – Record last update timestamp |
|
|
|
|
|
|
|
|
### Notes |
|
|
• At least one of reserves, current_tick, or current_bin is always populated. |
|
|
• Unique constraint: (pool_uid, block_number, tx_index, log_index) guarantees one snapshot per pool per event. |
|
|
• For Q64.96 sqrt price: mid_price = (current_sqrt_price / 2^96)^2, then adjust for token decimals. |
|
|
• Indexes on (pool_uid, block_number DESC, tx_index DESC, log_index DESC), (block_number, tx_index, log_index), and block_time support fast lookups. |
|
|
|
|
|
|
|
|
## Lineage |
|
|
Each reserves record includes deterministic _tracing_id, _genesis_tracing_ids, and _parent_tracing_ids, providing: |
|
|
|
|
|
• Provenance tracking from raw logs to decoded reserves snapshots |
|
|
• Reproducible analytics and signal extraction |
|
|
• Cross-system consistency checks (RPC vs. indexers vs. internal warehouses) |
|
|
|
|
|
|
|
|
## Common Use Cases |
|
|
• Reconstructing historical pool states for backtesting |
|
|
• TVL (Total Value Locked) calculations |
|
|
• Liquidity depth analysis and slippage estimation |
|
|
• Price impact modeling for concentrated liquidity pools |
|
|
|
|
|
|
|
|
## Quality |
|
|
• Verifiable lineage: deterministic cryptographic hashes per row |
|
|
• Reorg-aware ingestion: continuity and consistency across forks |
|
|
• Complete historical coverage: from chain genesis to present |
