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. `aave`, `spark`, `morpho`). 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 (e.g. `aave_v3`, `morpho_blue`). Qualifies the `project` field with version information, and is the codebase family that `project` deploys on. | | fee\_type | VARCHAR(16777216) | Fee leg within the protocol, passed through from the upstream intermediate (e.g. `interest_fee_shares_accrued` for Morpho Blue). Protocol-defined, so it varies by protocol. | | event\_name | VARCHAR(16777216) | The protocol event that produced this row (e.g. `AccrueInterest` on Morpho Blue). | | contract\_address | VARCHAR(42) | Address of the smart contract that emitted this event or was called in this transaction. | | market\_address | VARCHAR(16777216) | Market identifier the interest accrued on — the finest attribution available at this grain. | | fee\_token\_address | VARCHAR(42) | Loan token the interest is denominated in. | | fee\_token\_symbol | VARCHAR(16777216) | Ticker symbol of the loan token. | | fee\_amount | FLOAT | Interest accrued in loan-token units, decimals-adjusted. Upstream emits market supply-share units — a documented conversion gap. | | fee\_usd | FLOAT | Interest accrued in USD at the hourly token price. What borrowers 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 (suppliers for lending): `fee_usd` minus `revenue_usd`. NULL when the take rate is unconfirmed. | | fee\_sender | VARCHAR(42) | Address the fee was charged to, where the protocol's fee event names one. For `bad_debt` rows this is the user whose debt was written down. Null for protocol-level events. | | fee\_recipient | VARCHAR(42) | Address credited with the fee, where the protocol's fee event names one. Null for accrual events that socialize the fee across the market rather than paying a specific address. | | 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. | | block\_timestamp | TIMESTAMP\_NTZ(9) | Timestamp (UTC) of the block that contains this record. | | 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. | | \_created\_at | TIMESTAMP\_NTZ(9) | Timestamp of when the entry was created in the database. | | \_updated\_at | TIMESTAMP\_NTZ(9) | Timestamp of when the entry was last updated in the database. | ### Related Docs * [EVM Lending Fees](/historical-data/supported-blockchains/evm/core-schemas/lending/fees)
