What We Build

Multi-Currency Balances

Users hold separate balances in multiple currencies within a single account interface. Each currency wallet is independently funded and managed.

Currency Wallets

Distinct wallet-like sub-accounts per currency. Users can view balances, receive payments, make payouts, and initiate conversions within each currency wallet.

FX Quote & Conversion

Integrate a live FX rate feed and conversion workflow. Users see the exact rate, fee, and resulting amount before confirming a currency exchange.

Ledger System

A multi-currency double-entry ledger that accurately tracks all credits, debits, and conversions across currencies. Used as the source of truth for balances and reporting.

Deposits & Withdrawals

Receive funds in each supported currency via local payment rails (SEPA, ACH, Faster Payments, SWIFT). Withdraw to external bank accounts in the appropriate currency.

Admin Dashboard

Operational tools for managing multi-currency accounts, monitoring FX flows, reviewing exceptions, and running balance and transaction reports.

Reconciliation

Automated reconciliation between banking partner records and internal ledger entries for each currency. Exception handling and manual review tools.

KYC / KYB & Risk

User and business identity verification, AML screening, and transaction monitoring integrated from day one.

Payouts

Initiate payments from any currency wallet to external accounts in supported currencies. Support local payment rails per currency.

Compliance & Regulatory Note

Multi-currency account platforms are regulated as payment accounts or e-money products in most jurisdictions. KYC/KYB and AML controls are required. The banking partner carries certain regulatory obligations; your platform may also require payment institution or e-money licensing depending on structure and jurisdiction. We build the software platform and integrations; we do not provide banking or regulated payment services directly.

Frequently Asked Questions

How many currencies can the platform support?
There is no fixed limit. The supported currencies depend on the banking partners you integrate with and the payment rails available in each currency. Common starting points are EUR, GBP, USD, with additional currencies added based on your user base.
How does FX conversion work?
We integrate a live FX rate provider and build a conversion flow where the user selects source and target currencies, reviews the rate, fee, and resulting amount, and confirms the conversion. The execution is routed through the banking partner or FX provider. Rates have an expiry window.
Can users receive payments in each currency?
Yes. Each supported currency can have a corresponding virtual account with local payment instructions. A user can receive EUR via SEPA, GBP via Faster Payments, and USD via ACH — all landing in the same multi-currency account interface.
What banking partners can be integrated?
We integrate with providers such as Currencycloud, Wise Platform, ClearBank, Modulr, and others. The right partner depends on the currencies you need, the markets you serve, and the payment rails required.
Can the platform support stablecoin balances alongside fiat?
Yes. We build hybrid platforms that combine fiat multi-currency accounts (via banking partners) with stablecoin balances (via on-chain wallet infrastructure). This is a powerful architecture for platforms serving both fiat and crypto-native users.
What compliance is needed?
Multi-currency account products are regulated as payment accounts or e-money in most jurisdictions. KYC/KYB and AML controls are required. The banking partner carries some of the regulatory burden; your platform may also need licensing depending on structure. We build the compliance tooling; you work with legal partners to define obligations.
