| project | VARCHAR(16777216) | 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 | 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) | 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 | FLOAT | 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 | FLOAT | 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. |
