The context
Institutions need a way onto the new infrastructure.
Banks and financial institutions know the shift to quantum-secure, tokenized finance is coming. The challenge is participation: how to access this new infrastructure without rebuilding their stack, taking on unmanaged risk, or stepping outside their regulatory perimeter. Quantum Banks & QFIs is the on-ramp.
Building in-house is hard
Standing up quantum-secure, tokenized infrastructure internally demands rare expertise and years of work most institutions can't spare.
Regulatory perimeter matters
Institutions must adopt new infrastructure without stepping outside their licences, controls and supervisory obligations.
Fragmented point solutions
Adopting messaging, tokenization, stablecoins and payments piecemeal creates integration and governance overhead. A unified participant model removes it.
Full-stack access
A QFI can access the full platform — messaging & settlement, tokenization, stablecoin and payment infrastructure — through one participant relationship rather than separate integrations.
Within your perimeter
Infrastructure is deployed within the institution's own security and regulatory perimeter. The institution remains the regulated entity, retaining its licences, controls and supervisory relationships.
Governance & controls
Permissioned, role-based access and configurable policy controls let the institution govern who can do what — with full audit logging across every action.
Post-quantum security
Every service a QFI operates is secured with post-quantum cryptography at the protocol layer, protecting the institution through the quantum transition.
Capabilities
What becoming a QFI gives you.
A single participant model that brings the full Quantum Chain stack into the institution — secure, governed, and within its own regulatory perimeter.
Engage
The institution engages with the Quantum Chain team to define which services and use cases fit its strategy and regulatory position.
Integrate
Infrastructure is deployed and integrated within the institution's environment, connecting to its existing core systems.
Operate
The institution operates as a QFI, running its chosen services under its own governance, controls and supervisory relationships.
Expand
As needs evolve, the QFI activates additional services across the platform without new integrations from scratch.
How it works
From institution to QFI.
A structured path onto the network — at the institution's own pace, within its own controls.

Use cases
Who becomes a QFI.
Commercial banks
Banks
Commercial and corporate banks adopt quantum-secure messaging, settlement and payments, and offer tokenized services to their clients.
Central banks
Monetary authorities
Central banks explore quantum-secure infrastructure for settlement, digital currency and sovereign financial systems.
Financial institutions
Other regulated FIs
Asset managers, custodians and payment institutions join the network as QFIs to access the services relevant to their business.
