IDFE™

By bankers, for licensed institutions.

Anyone can build a payment app. The hard part is the licence, the ledger and the record underneath it.

Sealed layers. Like the compartments of a submarine, each layer of IDFE is isolated from the others: a change or a failure in one does not flood the rest.

PlatformIn developmentUnited Kingdom

Your business is your licence. The architecture underneath is ours. Financial infrastructure for licensed institutions: one ledger and one compliance gate for payments, digital assets, escrow and lending.

Once the architecture is in place, it is operated with attention to detail and kept current as the rules change. It is designed so that the payer and the payee behind each payment are identifiable.

Who it is forLicensed institutions — banks, payment and e-money institutions, crypto-asset service providers and custodians — that need one ledger and one compliance gate for several licensed activities, whether established institutions or new entrants. IDFE carries the infrastructure, so they can concentrate on their own licence and their own customers.

Why this architecture stands apart

Every gap between a licence, a ledger and a compliance check is where financial products fail. Technology is not the point; rules that enforce themselves are the point. An operation that breaks the rules does not fail an audit later — it does not happen. Operational flexibility is essential: a change of licensed operator need not stop the product. The architecture is extended as the needs of licensed institutions evolve.

One ledgerFiat and digital assets on the same ledger, each in its own unit. No second set of books.What the institution gets: no second set of books to reconcile.
One compliance gateKYC, velocity and sanctions checks on every operation; it fails safe to HOLD. Country- and status-specific restrictions are coded into the gate, not remembered by people. Compliance is enforced by the system, not by somebody remembering to check a list.What the institution gets: every operation checked before it executes.
Interchangeable licensed compartmentsEach module operated by the institution licensed for it; a change of operator need not stop the product.What the institution gets: continuity when an operator changes.
Provable by replayReconciliation, audit and reporting replayed from the ledger; any past day can be reconstructed. A register kept by hand is correct until it is not — and you find out during the audit.What the institution gets: any past day reconstructed on request.

Platform

One architecture, built once, serving every project in the Group. Infrastructure for licensed institutions cannot be improvised; it is approached with professional discipline.

IDFE™ — Integrated Digital Financial Ecosystem. The Group’s proprietary financial infrastructure for licensed institutions: one core ledger with interchangeable licensed compartments, built for the next generation of institutional participants.

IDFE is an IT solution. The licensed activity in each compartment is carried on by the licensed institution that operates it on the platform, under its own authorisation — not by the Group.

Philosophy and tagline

Re-engineering the Unchangeable. One integrated architecture. Multiple financial capabilities.

Core technology — FinOS and FinKernel

The ledger is the single source of financial truth. Identical inputs produce an identical ledger state.

FinKernel is the Group’s own work: a minimal set of ledger operations — send, mint, burn, lock, unlock, reserve, release and seize — with five invariants that must always hold: conservation of value, atomicity, determinism, an append-only ledger and explicit liabilities. Where the invariants hold, funds cannot disappear, liabilities cannot be hidden and an insolvency state is visible. These properties are designed to support the safeguarding, segregation and custody obligations that a licensed institution must meet.

FinOS runs the kernel on Formance, an open-source double-entry ledger engine, over PostgreSQL. Money logic is written once, in Numscript, and independently deployable services are built around it, covering payments, custody, escrow, lending, tokenisation of real-world assets and automated agents. Every transaction passes a single governance gate: KYC, velocity and sanctions checks run in parallel, the gate is designed to decide within 150 milliseconds, and it fails safe — to HOLD, never to open.

Not a better landline. A network of another kind.

Banks are becoming neobanks and neobanks are becoming banks, but both remain tied to one licence, one balance sheet and one jurisdiction. IDFE is designed differently.

  1. One client relationship. A licensed institution on IDFE can give its clients one account and one card, with IBANs intended in EUR, CHF and GBP. Fiat and digital assets sit on the same ledger, each in its own unit. The client does not move when the infrastructure behind them changes.
  2. Seamless by construction. A payment, a currency conversion, a digital-asset transfer, an escrow or a loan is one atomic operation under the same compliance gate: it completes in full or not at all. There is no second set of books and no reconciliation break.
  3. Interchangeable compartments. Payments, digital-asset services, collateralised lending and tokenisation are separate modules, each in an isolated ledger domain on a common core. Each is designed to be operated by any institution licensed for it, subject to its own approvals and the client’s consent. A change of operator or of law need not stop the product.
  4. Provable, not asserted. Reconciliation, audit and regulatory reporting are replayed from the ledger, not assembled from separate systems. Any past day can be reconstructed, and a review pack for a regulator, auditor or safeguarding bank can be produced from the same ledger state.

Current stage

  • FinKernel specified; FinOS under development.
  • Rails, card issuing, IBAN accounts and FX are currently delivered through third-party providers.
  • Performance figures are design targets, not achieved results: a 150 ms decision time for the gate and 99.99% availability.
  • Planned: independent certification of the platform and patent applications for FinKernel.

Boundaries

  • IDFE is the platform name, FinOS the operating system, FinKernel the kernel.
  • The Group provides IDFE as an IT solution to licensed institutions. It does not itself carry on any regulated activity or offer financial services to the public.
  • “Proprietary” refers to FinKernel. The ledger engine is open source.

The cost today

  • Several systems, several truths. Ask yourself: how many systems hold a different version of the same customer?
  • Compliance after the fact. Ask yourself: when did you last find an operation that should not have happened?
  • Reconciliation by hand. Ask yourself: how long does it take to rebuild a past day from your own records?

The balance between innovation and regulatory risk is managed in the architecture, not after it.

Before anything else: the Group is not a bank and not an operator. Anything regulated runs through the licensed institution, under its own authorisation.

Important. This page describes a project of The NeoBankers Group and its stage of development. It is not an offer or a financial promotion, and nothing on it is an invitation to use a regulated service. Where a project involves a regulated activity, that activity is carried on only by an entity holding the required authorisation, under its own authorisation. The NeoBankers Group Limited is not a bank and does not itself carry on regulated activities. Names marked ™ are trade marks of the Group.
