Transfer event logs emitted by ERC-721 (NFT) contracts. Each row is a transfer of a single non-fungible token, identified by its token_id.
Table Columns
| Column Name | Data Type | Description |
|---|---|---|
| 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). |
| 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_id | NUMBER(38,0) | Identifier for non-fungible tokens (ERC-721) or semi-fungible tokens (ERC-1155). Each unique token_id within a collection represents a distinct asset. |
| 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. |
| 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. |
| transaction_hash | VARCHAR(66) | 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_timestamp | TIMESTAMP_NTZ(9) | Timestamp (UTC) of the block that contains this record. |
| 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. |
