For token transfers, the account whose balance decreased. For transactions, the transaction sender (msg.sender). | | to\_address | VARCHAR(16777216) | Address that received in this event. For token transfers, the account whose balance increased. For transactions, the destination address (may be a smart contract). | | currency | VARCHAR(16777216) | Fiat currency this stablecoin is pegged to, as an ISO 4217 code in lowercase (e.g. `usd`, `eur`, `jpy`). | | 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"). | | raw\_amount\_str | VARCHAR(16777216) | Token amount in the smallest unit as a string. Same concept as `amount_raw_str` — the column is named `raw_amount_str` in models that follow the `raw_` prefix convention rather than the `_raw` suffix convention. | | raw\_amount | FLOAT | Token amount in the smallest indivisible unit (not decimal-adjusted). Same concept as `amount_raw` — the column is named `raw_amount` in models that follow the `raw_` prefix convention. | | usd\_amount | FLOAT | USD value of the token amount at the time of the event, computed using the hourly USD exchange rate. | | usd\_exchange\_rate | FLOAT | USD price per unit of the token at the time of the event, used to compute `usd_amount`. Sourced from Allium's hourly price feed. | | event\_type | VARCHAR(16777216) | Type or category of the onchain event that produced this record. The specific values depend on the model (e.g. `transfer_single` / `batch_transfer` for ERC-1155, `deposit` / `withdraw` for bridges). | | tx\_sender | VARCHAR(16777216) | Address that signed and submitted the transaction. | | transaction\_hash | VARCHAR(64) | 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\_timestamp | TIMESTAMP\_NTZ(9) | Timestamp (UTC) of the block that contains this record. | | 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\_hash | VARCHAR(64) | Cryptographic hash of the block header that contains this record. Uniquely identifies a block. | | block\_event\_kind | VARCHAR(16777216) | Block event kind if originating from a block event: begin, end, or finalize. | | block\_event\_index | NUMBER(38,0) | Block event index (null for transaction events). | | block\_event\_type | VARCHAR(16777216) | Block event type string (null for transaction events). | | code | NUMBER(38,0) | The bytecode of the contract | | tx\_success | BOOLEAN | True if the transaction executed successfully; false if it reverted. | | authz\_msg\_index | NUMBER(38,0) | Authz Message index within the transfer. | | memo | VARCHAR(16777216) | Memo for IBC transfers, if applicable. | | src\_channel | VARCHAR(16777216) | Source channel for the IBC transfer for inbound transfers. | | dst\_channel | VARCHAR(16777216) | Destination channel for the IBC transfer for inbound transfers. | | 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. | | amount\_str | VARCHAR(16777216) | Normalized token amount stored as a string to preserve full precision. Equivalent to `amount` but avoids floating-point truncation for very large or very small values. | | 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). | | 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. | | stablecoin\_currency | VARCHAR(16777216) | Fiat currency denomination of this stablecoin on Provenance (e.g., USD, EUR). | | base\_asset | VARCHAR(16777216) | Canonical name of the stablecoin (e.g. `USDC`, `USDT`, `DAI`). Groups together all deployments of the same stablecoin across chains and issuers. | | is\_bridge | BOOLEAN | True if this stablecoin token is a bridged representation (e.g. USDC bridged from Ethereum to an L2 via a third-party bridge). False if it is the canonical deployment by the issuer. | | \_metadata\_created\_at | TIMESTAMP\_NTZ(9) | Timestamp when the token metadata record was first created. | | \_metadata\_updated\_at | TIMESTAMP\_NTZ(9) | When the stablecoin metadata was last updated. | | event\_name | VARCHAR(16777216) | Name of the smart contract event that triggered this bridge record (e.g. `Deposit`, `Send`, `TransferInitiated`). | | is\_mint | BOOLEAN | Boolean flag indicating if this is a token minting event | | is\_burn | BOOLEAN | Boolean flag indicating if this is a token burning event | | \_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. |
