  name: Unstoppable Finance (Iron) Addresses API
  description: 'Wallet and bank account registration


    Every wallet address that interacts with Iron must be registered (linked) to a customer **before** it can be used in any
    flow — onramp, offramp, or swap. This is a regulatory requirement under the **Travel Rule**, which obliges Virtual Asset
    Service Providers to exchange originator and beneficiary information for crypto transfers.


    Iron supports two wallet types:


    - **Self-hosted wallets** — the customer controls the private key. Registration requires a signed proof-of-ownership message.

    - **Hosted wallets** — the wallet is custodied by another VASP (e.g. Coinbase, Kraken). Registration requires the VASP''s
    DID so Iron can exchange travel-rule data with the custodian.


    Similarly, fiat bank accounts must be registered before they can receive offramp payouts.'
