### Table Columns

| Column Name                | Data Type         | Description                                                                                                                                                                                                                                              |
| -------------------------- | ----------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| chain                      | VARCHAR(16777216) | Slug identifying the blockchain this record belongs to (e.g. `ethereum`, `base`, `avalanche`, `solana`). In per-chain tables this is always the same value; in cross-chain tables it identifies which chain the row came from.                           |
| facilitator\_id            | VARCHAR(16777216) | Unique identifier of the x402 facilitator that routed this payment or is registered in the facilitator registry.                                                                                                                                         |
| facilitator\_name          | VARCHAR(16777216) | Human-readable name of the x402 facilitator (e.g. "Coinbase", "Stripe", "Allium").                                                                                                                                                                       |
| block\_timestamp           | TIMESTAMP\_NTZ(9) | Timestamp (UTC) of the block that contains this record.                                                                                                                                                                                                  |
| token\_address             | VARCHAR(42)       | 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").                                                                                                                                                                                                        |
| 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                     | 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(42)       | 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(42)       | Address that received in this event. For token transfers, the account whose balance increased. For transactions, the destination address (may be a smart contract).                                                                                      |
| transaction\_from\_address | VARCHAR(42)       | 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(42)       | 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(66)       | Hash of the transaction that produced this record. Uniquely identifies a transaction within the blockchain.                                                                                                                                              |
| 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\_hash                | VARCHAR(66)       | 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.                                                                                                                                                                                            |
