Consistent across verticals — every table with a `project` column uses this field to identify the top-level protocol brand. | | protocol | VARCHAR(16777216) | Specific version or variant of the protocol (e.g. `uniswap_v3`, `aave_v2`, `stargate_v2`). Qualifies the `project` field with version information. | | contract\_address | VARCHAR(16777216) | Address of the smart contract that emitted this event or was called in this transaction. | | event\_name | VARCHAR(16777216) | Source SettlementPool event name: Deposited or Withdrawn. | | direction | VARCHAR(16777216) | Direction of this transfer relative to the chain where the event occurred. `outbound` = tokens leaving the chain; `inbound` = tokens arriving on the chain. | | source\_chain | VARCHAR(16777216) | Slug of the chain where the tokens originated. | | destination\_chain | VARCHAR(16777216) | Slug of the chain where the tokens are being sent. | | sender\_address | VARCHAR(16777216) | Address that initiated the bridge transfer on the source chain. | | recipient\_address | VARCHAR(16777216) | Address that will receive the tokens on the destination chain. May be null if the destination address is not emitted in the source-chain event. | | token\_address | VARCHAR(16777216) | Contract address of the token. For EVM chains, native currency (e.g. ETH, MATIC) is represented as the zero address (0x0000000000000000000000000000000000000000). For Solana, this is the mint address. | | token\_name | VARCHAR(16777216) | Full name of the token (e.g. "USD Coin", "Wrapped Ether"). | | token\_symbol | VARCHAR(16777216) | Ticker symbol of the token (e.g. "USDC", "WETH"). | | amount\_raw | VARCHAR(16777216) | Token amount expressed in the token's smallest indivisible unit (i.e. not divided by decimals). Use `amount` for the human-readable normalized value. | | amount | VARCHAR(16777216) | Token amount normalized by the token's decimal precision (amount\_raw / 10^decimals). This is the human-readable value (e.g. 1.5 USDC rather than 1500000). | | usd\_amount | FLOAT | USD value of the token amount at the time of the event, computed using the hourly USD exchange rate. | | fee\_token\_address | VARCHAR(16777216) | Contract address of the token used to pay the bridge protocol fee. May differ from the bridged token (e.g. fees paid in the native gas token). | | fee\_token\_name | VARCHAR(16777216) | Full name of the token used to pay the bridge fee. | | fee\_token\_symbol | VARCHAR(16777216) | Ticker symbol of the token used to pay the bridge fee. | | fee\_amount\_raw | VARCHAR(16777216) | Raw amount of the bridge fee in the fee token's smallest unit (not decimal-adjusted). | | fee\_amount | VARCHAR(16777216) | Decimal-adjusted amount of the bridge fee. | | fee\_usd\_amount | FLOAT | USD value of the bridge fee at the time of the transfer. | | fee\_details | VARIANT | JSON object containing a breakdown of fee components (e.g. protocol fee, gas rebate, relayer fee). Structure varies by bridge protocol. | | message\_details | VARIANT | JSON object containing the payload of a cross-chain message (e.g. calldata, encoded parameters, target contract). Structure varies by messaging protocol. | | extra\_fields | VARIANT | Protocol-specific fields as a JSON object. Keys: transfer\_uuid (transfer identifier, uint128 as varchar, from the event). | | transaction\_hash | VARCHAR(16777216) | 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. | | event\_index | NUMBER(38,0) | Zero-based index of this event within its transaction. The specific semantics depend on the chain — on Aptos this is the `event_index` within the transaction; on Cosmos this is within the message. | | block\_height | NUMBER(38,0) | Number of confirmed blocks between this block and the genesis block (inclusive). Unlike `block_slot`, this only increments for slots that produced a block. | | block\_timestamp | TIMESTAMP\_NTZ(9) | Timestamp (UTC) of the block that contains this record. | | block\_hash | VARCHAR(16777216) | Cryptographic hash of the block header that contains this record. Uniquely identifies a 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. | | \_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. |
