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. | | messaging\_protocol | VARCHAR(16777216) | Name of the cross-chain messaging layer used for this transfer (e.g. `layerzero`, `wormhole`, `hyperlane`, `ccip`). Populated when the bridge uses a dedicated messaging protocol layer distinct from the bridge itself. | | contract\_address | VARCHAR(16777216) | Address of the smart contract that emitted this event or was called in this transaction. | | event\_name | VARCHAR(16777216) | Name of the smart contract event that triggered this bridge record (e.g. `Deposit`, `Send`, `TransferInitiated`). | | 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\_type | VARCHAR(16777216) | Token standard for the asset. One of: `erc20` (fungible), `erc721` (non-fungible), `erc1155` (semi-fungible), or the native currency symbol (e.g. `eth`, `matic`, `bnb`). | | 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"). | | token\_id | VARCHAR(16777216) | Identifier for non-fungible tokens (ERC-721) or semi-fungible tokens (ERC-1155). Each unique token\_id within a collection represents a distinct asset. | | 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. | | 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). | | transaction\_from\_address | VARCHAR(16777216) | Address of the externally-owned account (EOA) that signed and submitted the transaction. This is the wallet that paid gas, which may differ from the `from_address` of an individual token transfer if a contract is routing tokens on behalf of a user. | | transaction\_to\_address | VARCHAR(16777216) | Address the transaction was sent to (the top-level `to` field of the transaction). May be a router, aggregator, or bridge contract rather than the direct recipient of assets. | | 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. | | 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. | | 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. | ### Related Docs * [EVM Bridges Bridges Outbound Transfers](/historical-data/supported-blockchains/evm/core-schemas/bridges/bridges-outbound-transfers)
