      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.
