Unstoppable Finance (Iron) Addresses API
Wallet and bank account registrationEvery 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.
