### Table Columns

| Column Name | Data Type | Description |
| - | - | - |
| product\_id | VARCHAR(16777216) | Internal Allium identifier for the stablecoin product. Groups together the canonical and bridged variants of the same stablecoin on the same chain. |
| is\_native | BOOLEAN | True if this is the issuer's canonical deployment on this chain (not a bridge-wrapped version). |
| stablecoin\_type | VARCHAR(16777216) | Classification of the stablecoin mechanism. Values include `fiat_backed` (e.g. USDC, USDT), `crypto_backed` (e.g. DAI), `algorithmic`, or `yield_bearing`. |
| currency | VARCHAR(16777216) | Fiat currency this stablecoin is pegged to, as an ISO 4217 code in lowercase (e.g. `usd`, `eur`, `jpy`). |
| 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). |
| token\_acc\_from | VARCHAR(16777216) | SPL token account address of the sender. Each SPL token balance is held in a token account (derived from owner + mint), not the wallet address directly. |
| token\_acc\_to | VARCHAR(16777216) | SPL token account address of the recipient. Each SPL token balance is held in a token account (derived from owner + mint), not the wallet address directly. |
| mint | VARCHAR(16777216) | Base58-encoded mint address of the SPL token. Analogous to `token_address` on EVM chains. Each mint uniquely identifies a fungible or non-fungible token on Solana. |
| decimals | FLOAT | Number of decimal places for this token. Short alias for `token_decimals` used in tables that preserve the original blockchain field naming convention. |
| 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 | 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. |
| raw\_amount\_str | VARCHAR(16777216) | Raw collateral amount in USDC base units (6 decimals), as a string. |
| 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). |
| 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. |
| 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. |
| is\_dex\_price | BOOLEAN | Whether the USD price used for this record was sourced from Solana DEX data rather than an external market feed (e.g. CoinGecko). |
| signer | VARCHAR(16777216) | Primary signing account (fee payer) of the transaction. This is the account that authorized the transaction and paid transaction fees. |
| block\_slot | NUMBER(38,0) | Solana slot number in which this transaction was confirmed. Slots are the fundamental unit of time on Solana (analogous to block numbers on EVM chains). Not every slot produces a block. |
| 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. |
| txn\_id | VARCHAR(16777216) | Base58-encoded transaction signature on Solana. Analogous to `transaction_hash` on EVM chains. Uniquely identifies a transaction. |
| txn\_index | NUMBER(38,0) | Zero-based position of this transaction within its slot. |
| instruction\_index | NUMBER(38,0) | Zero-based position of this instruction within the transaction's top-level instructions array. |
| inner\_instruction\_index | NUMBER(38,0) | Zero-based position of this inner instruction within its parent instruction's inner instructions array. -1 for top-level instructions that are not inner instructions. |
| program\_name | VARCHAR(16777216) | Human-readable name of the Solana program (e.g. "spl\_token", "system\_program", "jupiter\_v6"). Resolved from Allium's program registry. |
| program\_id | VARCHAR(16777216) | Base58-encoded public key of the Solana program that processed this instruction (e.g. `TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA` for SPL Token). |
| type | VARCHAR(16777216) | The type of the position on the perpetual. |
| 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`. |
| outer\_program\_id | VARCHAR(16777216) | Program ID of the outermost instruction that invoked this inner instruction on Solana |
| 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. |
| \_transfer\_created\_at | TIMESTAMP\_NTZ(9) | Timestamp when the underlying transfer record was first ingested. |
| \_transfer\_updated\_at | TIMESTAMP\_NTZ(9) | Timestamp when the underlying transfer record was last updated. |
| \_metadata\_updated\_at | TIMESTAMP\_NTZ(9) | When the stablecoin metadata was last updated. |
| \_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. |
