In per-chain tables this is always the same value; in cross-chain tables it identifies which chain the row came from. | | 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`). | | coin\_type | VARCHAR(16777216) | Fully-qualified Aptos coin type identifier (e.g. `0x1::aptos_coin::AptosCoin`). Alias for `aptos_coin_type` used in Aptos models that name the column `coin_type`. | | coin\_name | VARCHAR(16777216) | Full name of this coin. Short alias for token\_name in Aptos/Cosmos-style tables. | | coin\_symbol | VARCHAR(16777216) | Ticker symbol of this coin. Short alias for token\_symbol in Aptos/Cosmos-style tables. | | decimals | NUMBER(38,0) | Number of decimal places for this token. Short alias for `token_decimals` used in tables that preserve the original blockchain field naming convention. | | raw\_amount\_str | VARCHAR(16777216) | Raw collateral amount in USDC base units (6 decimals), as a string. | | 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. | | 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). | | 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. | | from\_address | VARCHAR(16777216) | Address that initiated or sent from in this event. 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). | | tx\_sender | VARCHAR(16777216) | Address that signed and submitted the transaction. | | transfer\_type | VARCHAR(16777216) | Category of this token movement. For native currency transfers: `value_transfer` (explicit send), `gas_payment_to_miner` (priority fee to block producer), or `gas_burn` (EIP-1559 base fee destroyed). For token transfers: always `value_transfer`. | | 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 | | transaction\_block\_digest | VARCHAR(16777216) | Base58-encoded digest of the Sui transaction block. Alias for `sui_transaction_digest`. | | checkpoint\_timestamp | TIMESTAMP\_NTZ(9) | Timestamp (UTC) of when the Sui checkpoint was created. Alias for `sui_checkpoint_timestamp`. | | checkpoint\_date | DATE | Date and time of the checkpoint | | checkpoint\_sequence | NUMBER(38,0) | Monotonically increasing sequence number of the Sui checkpoint. Alias for `sui_checkpoint_sequence` used in models that drop the chain prefix. | | checkpoint\_digest | VARCHAR(16777216) | Hash digest of the Sui checkpoint. Alias for `sui_checkpoint_digest`. | | 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. | | \_rwa\_token\_created\_at | TIMESTAMP\_NTZ(9) | Timestamp (UTC) when this token was first added to the Allium RWA token registry. | | \_transfers\_created\_at | TIMESTAMP\_NTZ(9) | Timestamp (UTC) when the underlying transfer record that feeds this row was first created. | | \_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. | | \_changed\_since\_full\_refresh | BOOLEAN | Indicates if the record has changed since the last full data refresh. |
