### Table Columns

| Column Name         | Data Type         | Description                                                                                                                                                                                             |
| ------------------- | ----------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| sector              | VARCHAR(16777216) | The fee sector this row belongs to (`dex`, `lending`, `chain`, `liquid_staking`, ...). Every sector shares the same three fee layers; only the atomic grain and where fee info comes from change.       |
| chain               | VARCHAR(16777216) | Slug identifying the blockchain this record belongs to (e.g. `ethereum`, `base`, `avalanche`). In per-chain tables this is always the same value; in cross-chain tables it identifies the source chain. |
| project             | VARCHAR(16777216) | Business name of the protocol being used (e.g. `lido`, `rocket_pool`). Consistent across verticals — every table with a `project` column uses this field for the top-level brand.                       |
| protocol            | VARCHAR(16777216) | Specific version or variant of the protocol. Qualifies the `project` field with version information.                                                                                                    |
| fee\_type           | VARCHAR(16777216) | Fee leg within the protocol, passed through from the upstream intermediate. Protocol-defined, so it varies by protocol rather than naming a product.                                                    |
| event\_name         | VARCHAR(16777216) | The protocol event that produced this row.                                                                                                                                                              |
| contract\_address   | VARCHAR(42)       | Address of the smart contract that emitted this event or was called in this transaction.                                                                                                                |
| fee\_token\_address | VARCHAR(42)       | Contract address of the token the fee was charged in.                                                                                                                                                   |
| fee\_amount         | FLOAT             | Fee charged in fee-token units, decimals-adjusted.                                                                                                                                                      |
| fee\_usd            | FLOAT             | Fee charged in USD at the hourly token price. What stakers paid.                                                                                                                                        |
| take\_rate          | FLOAT             | Fraction of the fee accruing to the protocol, from the revenue registry. 0 is a confirmed zero protocol share (fee switch verified off), distinct from NULL, which means unconfirmed.                   |
| revenue\_usd        | FLOAT             | Protocol revenue accrued on this row in USD: `fee_usd` x `take_rate`. NULL when the take rate is unconfirmed, never silently 0.                                                                         |
| supply\_side\_usd   | FLOAT             | The supply side's share of the fee in USD (node operators and stakers for liquid staking): `fee_usd` minus `revenue_usd`. NULL when the take rate is unconfirmed.                                       |
| fee\_recipient      | VARCHAR(42)       | Address credited with the fee, where the protocol's fee event names one. Null when the event does not name a recipient.                                                                                 |
| extra\_fields       | VARIANT           | JSON object containing additional fields from the onchain event that are not part of the standard schema (e.g. nonce, fee metadata, protocol-specific parameters).                                      |
| methodology         | VARCHAR(16777216) | Slug of the fee derivation methodology, resolvable in `crosschain.metrics.fees_coverage_and_methodology` where the derivation and its citation are published.                                           |
| transaction\_hash   | VARCHAR(66)       | Hash of the transaction that produced this record. Uniquely identifies a transaction within the blockchain.                                                                                             |
| transaction\_index  | NUMBER(38,0)      | Zero-based position of the transaction within its block. The first transaction in a block has index 0.                                                                                                  |
| log\_index          | NUMBER(38,0)      | Zero-based position of this event log within its transaction. The first log emitted by a transaction has index 0.                                                                                       |
| block\_number       | NUMBER(38,0)      | Sequential number of the block that contains this record. Starts at 0 (genesis block) and increments by 1 for each new block.                                                                           |

| unique\_id          | VARCHAR(16777216) | Allium's deterministic unique identifier for this row. Generated from the fields that uniquely identify the record (e.g. transaction hash + log index). Stable across full refreshes.                   |
