We build the infrastructure layer behind crypto-native, hybrid fiat-crypto, and stablecoin-first neobank products. That usually means the ledger, wallet and account orchestration, payout routing, reconciliation, compliance integrations, treasury controls, and the internal tooling required to run the platform in production.
Ledger, wallet, and account orchestration in one operating model
Fiat rails and stablecoin rails normalized behind one backend
Compliance, treasury, reconciliation, and admin tooling built into the stack
Neobank infrastructure is not a single module. It is a coordinated system that has to maintain a reliable source of truth while handling multiple asset types, providers, and operational states.
Control Layer
Ledger and balance infrastructure
Design a ledger that tracks user balances, treasury movements, fees, reserves, and operational adjustments with explicit balance states and auditability.
Double-entry logic and transaction history
Pending, available, reserved, and settled balance states
Internal source of truth for support and finance teams
Reconciliation hooks into provider and chain events
Orchestration
Wallets, accounts, and money movement
Implement wallet infrastructure, deposit address handling, virtual account rails, payout routing, sweep logic, and exception-aware movement across providers.
Custodial wallet orchestration and on-chain event ingestion
Virtual account or virtual IBAN integrations
Fiat deposits, withdrawals, and stablecoin payout flows
Routing logic and approval-aware payout handling
Operations
Compliance, treasury, and admin tooling
Embed KYC, KYB, sanctions screening, wallet screening, reconciliation, treasury controls, and internal dashboards into the way the platform actually runs.
Manual review queues and case handling
Treasury approvals, reserve views, and operator permissions
Transaction investigation and reporting exports
Webhook monitoring, audit trails, and exception management
Technical Architecture
The product surface is only one layer.
The exact architecture depends on jurisdiction, partner stack, and product model, but most neobank systems share the same five-layer structure: user-facing product surfaces, an orchestration backend, provider integrations, control tooling, and an audit-aware data layer.
Hybrid rails by design
Stablecoin and fiat rails should behave like parts of the same system, not disconnected features.
Provider insulation
A clean integration layer makes future provider changes less painful and protects the core product model.
Operational visibility
Finance, compliance, and support teams need dashboards, queues, and audit logs inside the product itself.
Controlled reporting
Auditability should be designed into event storage and export workflows from the start.

Build Scope
MVP first. Then complexity.
MVP Scope
A narrow, operable first build with clear controls.
One core account model, such as stablecoin balances, hybrid fiat-stablecoin accounts, or a wallet-ledger product
One primary money-in flow and one primary payout flow
Core ledger and transaction history
Basic KYC or KYB onboarding
Compliance and screening integrations for required flows
Admin tooling for support, manual review, and balance investigation
Reconciliation for the initial provider stack
Advanced Platform Scope
Capabilities to add once the core system is live and operable.
Multiple currencies and multi-chain support
More than one banking or wallet provider
Smarter payout routing across cost, speed, or geography
Treasury automation and reserve balancing
Internal transfers across sub-accounts or entities
Card issuing or spend controls
FX workflows
More advanced risk rules and case management
Partner or API-facing platform capabilities
Why Work With Us
Built for the seams that usually break.
Operational systems lens
We treat neobank infrastructure as a controls and operations problem, not just a stack of APIs or frontend flows.
Hybrid rails experience
We work across stablecoin, wallet, banking, and payment systems, which matters when blockchain and traditional rails need to coexist cleanly.
Control-layer thinking
We focus on the seams that usually break first: ledger versus actual funds movement, provider events versus user-visible balances, and compliance rules versus usable product flows.
Phased build discipline
We scope narrow MVPs with explicit controls first, then add multi-provider and multi-rail complexity in later phases.
Compliance and Regulatory Boundaries
Software build and licensed activity are not the same thing.
We build the software platform and integration layer around regulated partners. Banking services, e-money services, custody, card issuance, payment execution, or other regulated functions are provided by the licensed entities in your operating model. The right product structure depends on jurisdiction, user geography, asset model, and the specific permissions of your partners.
Who holds customer funds or crypto assets
Which entity controls transaction approval and monitoring
Whether balances are e-money, deposits, stablecoin claims, or something else
How treasury and safeguarding arrangements are handled
Neobank infrastructure is the backend and operations layer that supports a digital banking-style product. It usually includes the ledger, account and wallet systems, payment rail integrations, compliance workflows, reconciliation logic, treasury controls, and admin tooling needed to operate the product.
How is neobank infrastructure different from a neobank app?
The app is the customer-facing surface. The infrastructure is the system underneath it. A polished app can still fail operationally if the underlying ledger, reconciliation, compliance, or treasury workflows are weak.
Can you build infrastructure for a crypto neobank?
Yes. That usually involves stablecoin wallet infrastructure, on-chain transaction handling, wallet screening, treasury workflows, and a ledger that can accurately reflect blockchain and partner-side activity together.
Can a stablecoin neobank also support fiat rails?
Yes. Many products use a hybrid architecture with stablecoin balances or settlement on one side and banking rails for deposits, withdrawals, or local account functionality on the other. The complexity sits in the orchestration and control layer, which is part of what we build.
Do you provide the regulated banking or custody service directly?
No. We build the software platform and integrate licensed partners where needed. Regulated services are provided by the relevant banking, payment, custody, or compliance partners in the product structure.
What is the right MVP for a neobank infrastructure build?
Usually the right MVP is narrower than founders expect. It should focus on one account model, a controlled set of money movement flows, a dependable ledger, the required compliance controls, and enough admin tooling to operate the product safely.
Do we need a ledger if our providers already track balances?
Usually, yes. Provider balances are not a sufficient product control layer on their own. A platform ledger gives you an internal source of truth for balances, fees, reconciliation, support investigations, and product-specific transaction logic.
How long does a neobank infrastructure build take?
That depends on product scope and partner readiness. A focused MVP around one product model and a limited provider stack can often be scoped in a few months. More complex platforms with multiple rails, providers, and internal workflows are materially larger engagements.
Get Started
Scope the stack before it breaks.
If you are planning a crypto or stablecoin neobank, the infrastructure decisions usually matter more than the first interface decisions. We can help define the architecture, phased scope, and implementation path.
