| 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. |
| address | VARCHAR(16777216) | Wallet or contract address of the account. On EVM chains, a 42-character hex string (0x-prefixed). On other chains, the native address format applies. |
| 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. |
| 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”). |
| token_decimals | NUMBER(38,0) | Number of decimal places used to represent the token’s smallest unit. Used to convert raw amounts: normalized_amount = raw_amount / 10^decimals. For example, USDC has 6 decimals, so 2500000 raw units = 2.5 USDC. |
| 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. |
| ncs_address_type | VARCHAR(16777216) | Classification of an address in the NCS (Net Currency Supply) framework. Indicates whether the address is an issuer, smart contract, exchange, or user wallet. |
| ncs_address_label | VARCHAR(16777216) | Human-readable label for the address in the NCS framework (e.g. the name of an exchange, protocol, or issuer). |
| ncs_supply_layer | VARCHAR(16777216) | Supply layer classification in the NCS framework. Indicates whether this balance is part of the circulating supply, non-circulating supply, or a specific custodial layer. |
| raw_balance_str | VARCHAR(16777216) | Token balance in the smallest unit, stored as a string for full precision. Avoids floating-point truncation for tokens with very large integer balances. |
| raw_balance | FLOAT | Token balance in the token’s smallest unit (not decimal-adjusted). Use balance for the human-readable normalized value. |
| balance_str | VARCHAR(16777216) | Normalized token balance stored as a string for full precision. Equivalent to balance but avoids floating-point truncation. |
| balance | FLOAT | Token balance normalized by the token’s decimal precision (raw_balance / 10^decimals). Human-readable value (e.g. 1.5 USDC rather than 1500000). |
| block_date | TIMESTAMP_NTZ(9) | Calendar date (UTC) derived from block_timestamp. Used as a partition key in incremental models. |
| 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(16777216) | Cryptographic hash of the block header that contains this record. Uniquely identifies a block. |
| _ncs_seed_updated_at | TIMESTAMP_NTZ(9) | Timestamp (UTC) of the most recent update to the NCS (Net Currency Supply) seed data that enriches this record. |
| _short_address | VARCHAR(4) | Truncated version of the address column used as a clustering/partition key. Contains only the first few bytes of the address to improve query performance on large tables. |
| _short_token_address | VARCHAR(4) | Truncated version of the token_address column used as a clustering/partition key. Contains only the first few bytes of the token address to improve query performance on large tables. |
| _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. |
