### Table Columns

| Column Name    | Data Type | Description                                                                                                                                                                                                                    |
| -------------- | --------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| project        |           | Business name of the protocol being used (e.g. `uniswap`, `aave`, `lido`, `paraswap`). Consistent across verticals — every table with a `project` column uses this field to identify the top-level protocol brand.             |
| protocol       |           | Specific version or variant of the protocol (e.g. `uniswap_v3`, `aave_v2`, `stargate_v2`). Qualifies the `project` field with version information.                                                                             |
| version        |           | Protocol version.                                                                                                                                                                                                              |
| chain          |           | Slug identifying the blockchain this record belongs to (e.g. `ethereum`, `base`, `avalanche`, `solana`). In per-chain tables this is always the same value; in cross-chain tables it identifies which chain the row came from. |
| pair\_index    |           | Protocol-native numeric identifier of the trading pair. Used by the protocol's contracts to reference this market.                                                                                                             |
| market\_symbol |           | Market symbol (e.g. SOL-USD).                                                                                                                                                                                                  |
| from\_symbol   |           | Symbol of the base asset being traded (the asset whose price the market tracks).                                                                                                                                               |
| to\_symbol     |           | Symbol of the quote asset the market is denominated in.                                                                                                                                                                        |
| max\_leverage  |           | Maximum leverage the protocol permits on this market.                                                                                                                                                                          |
| extra\_fields  |           | JSON object containing additional protocol-specific fields for this market that are not part of the standard schema.                                                                                                           |
| unique\_id     |           | Allium's deterministic unique identifier for this row. Generated from the fields that uniquely identify the record. Stable across full refreshes.                                                                              |
