# Sanctioned Addresses

`allium_identity.sanctions.addresses`

Blockchain addresses sanctioned by OFAC or other regulatory bodies, with their identifying attribution\_id linking back to the source sanctions registry.

<Warning>
  This dataset is provided for screening and research. It reflects Allium's
  attribution of addresses to sanctions-list entities and is not legal advice or
  a compliance determination. Always confirm against the primary regulatory
  source before acting.

## Schema

| Column Name       | Description                                                                                                                                                                                                                    |
| ----------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| chain             | 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           | 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.                                                                         |
| label             | Label tagged to the address, in lower-casing. There can be multiple labels tagged to an address.                                                                                                                               |
| entity            | Name or label of the entity (organization, protocol, or project) associated with this record. Used in app\_users and identity models.                                                                                          |
| category          | Category or classification label for this record. The specific taxonomy depends on the model context (e.g. token category, transfer category, metric category).                                                                |
| attribution\_date | Calendar date (UTC) for which address attribution scores were computed.                                                                                                                                                        |
| chain\_group      | Group of chains associated with this attributed entity.                                                                                                                                                                        |
| attribution\_id   | Internal identifier linking a sanctioned address to its source record in the sanctions registry (e.g., OFAC SDN list entry).                                                                                                   |
| \_updated\_at     | Timestamp (UTC) of the most recent update to this row in the Allium platform. Advances when the row is reprocessed or enriched (e.g. USD price hydration).                                                                     |

## Notes

* One row per `(chain, address)` per attribution; an address sanctioned on
  several chains appears once per chain.
* `attribution_id` links back to the source registry entry (e.g. an OFAC SDN
  list record), so you can trace any row to its origin.
* Addresses on Tron, Solana and Bitcoin Base58 are case-sensitive — do not
  lowercase before joining.
