UR Account

A hybrid financial account bridging the regulated financial system with on-chain settlement.

The UR Account is a hybrid financial infrastructure that bridges the regulated financial system (via UR's regulated entity) with Web3 settlement rails. It functions as the user's regulated fiat account linked to an active URID.

Fiat balances are issued as tokenized deposits (e.g., USD24, EUR24) on Mantle Network, backed 1:1 by fiat reserves held by UR's regulated entity. This architecture provides users with a fully compliant account interface (including personal Swiss IBANs and Mastercard debit card capabilities) while enabling instant, atomic on-chain settlement for crypto-to-fiat conversions, card spending, and cross-border transfers.

How a UR Account holds assets

Every UR Account is backed by an on-chain wallet address on Mantle Network. Tokenized deposits (e.g., USD24, EUR24) are ERC-20 tokens held at this address.

How assets are split depends on the integration mode:

• Managed Custody Mode: UR manages the user's fiat account (tokenized deposits, IBAN, card). The UR-managed account holds fiat only; the user's crypto is always held in a separate external (non-UR) wallet (partner-side or the user's own). Crypto enters the UR Account only via off-ramp, which credits fiat.

• External Wallet Access Mode: Both fiat (tokenized deposits) and crypto live in the user's single external wallet. The UR Account and the user's wallet are the same address.

• Delegated Mode: Similar to Managed Custody Mode; UR manages the wallet via delegated smart contracts. The user performs a one-time delegation during onboarding.

Delegated Mode will be deprecated soon and is being replaced by Managed Custody Mode. New partners should use Managed Custody Mode or External Wallet Access Mode.

In all three modes, the UR Account provides a regulated Swiss IBAN account issued by UR's regulated entity (for fiat rails, IBAN, and card), with on-chain settlement for all operations.

What a UR Account includes

• Personal Swiss IBAN: receive SEPA Instant and SWIFT transfers directly

• Multi-currency balances: hold EUR, USD, CHF, CNH, SGD, JPY, and HKD as tokenized deposits

• Mastercard debit card: spend fiat balances anywhere Mastercard is accepted; settlement happens on-chain in milliseconds

• Instant FX: convert between supported currencies atomically (burn one token, mint another in a single transaction)

• On-chain transparency: balances and transactions are recorded on Mantle Network, fully auditable

Account structure by integration mode

How the account is provisioned depends on how your platform integrates with UR:

• Managed Custody Mode (recommended): UR manages a fiat account per user (tokenized deposits, IBAN, card). The UR-managed account holds fiat only; the user's crypto is always held in a separate external (non-UR) wallet (partner-side or the user's own). The partner backend orchestrates all fiat actions via API.

• External Wallet Access Mode: Users connect their own wallet (e.g., MetaMask, SafePal). The URID is minted directly to their address, and they interact with UR through your UI or directly on-chain.

• Delegated Mode: Legacy API-driven integration via delegated smart contracts. Existing partners on this mode continue to be supported, but the mode will be deprecated soon (see the note above).
