How mapping works
Key definitions
Mapping: The approved link between a digital wallet (on a specific chain) and its dedicated vIBAN. Each mapping covers one wallet, one chain, and one currency (e.g. EURAU on Ethereum).
Virtual IBAN (vIBAN): A dedicated payment address generated by AllUnity for each mapping, held under AllUnity GmbH. It is not a bank account you log into; it functions as a routing identifier. Fiat arriving at the vIBAN is automatically recognized as a minting instruction for the linked wallet.
Whitelisted bank accounts: The bank accounts your organization verifies during onboarding. Any of them can fund any of your mappings.
Why mappings matter
Mappings ensure funds only ever move between endpoints you have verified and AllUnity has approved. The vIBAN removes all manual routing: minting is triggered only by funds from whitelisted accounts and stablecoins are delivered only to the designated wallet. This design:
Eliminates routing errors: No misdirected funds or manually entered wallet addresses.
Prevents unauthorized flows: Transfers from non-whitelisted accounts never trigger minting.
Creates a clear audit trail: Every mint is traceable to an approved account, vIBAN, and wallet.
Enables full automation: issuance happens on funds arrival, with no API integration needed.
