The context
Stablecoins are entering the regulated era.
As stablecoin frameworks take shape across major jurisdictions, licensed issuers face a higher bar: provable reserves, robust controls, transparent reporting, and security that lasts. Q-Stables is the infrastructure that lets regulated issuers meet that bar — Quantum Chain provides the technology; the issuer holds the reserves and carries the regulatory obligations.
Transparency is now table stakes
Holders and supervisors increasingly expect verifiable, on-chain evidence of backing — not periodic attestations alone.
Rising regulatory expectations
New frameworks require licensed issuers to demonstrate reserve adequacy, governance and reporting to a standard most early stablecoin stacks were never built for.
Security that must endure
A stablecoin in circulation for years needs cryptography that remains secure through the transition to quantum computing.
Lifecycle issuance & management
Tooling for licensed issuers to mint and redeem fiat-referenced stablecoins under their own governance, with configurable controls aligned to their regulatory permissions.
Reserve transparency tooling
Infrastructure to support proof-of-reserve reporting, giving the issuer the means to evidence backing to supervisors and holders. The reserves themselves are held and managed by the issuer.
Compliance & policy controls
Configurable controls — eligibility, allow-lists, transfer rules and screening — to support the issuer's AML, sanctions and jurisdictional obligations.
Post-quantum security
Stablecoins are secured with post-quantum cryptography at the protocol layer, so instruments remain protected through the transition to quantum computing.
Capabilities
What Q-Stables provides.
Infrastructure for licensed issuers to deploy and operate fiat-referenced stablecoins — with security, controls and transparency built in. Reserves are held by the issuer; Quantum Chain provides the technology layer.
Back
The licensed issuer holds reserves in line with its regulatory requirements, and connects them to the platform for reporting.
Issue
The issuer mints fiat-referenced stablecoins on a post-quantum secure ledger, under its own governance and controls.
Circulate
Stablecoins move between eligible parties, with transfer rules, screening and policy controls enforced automatically.
Redeem & report
Holders redeem against the issuer's reserves, while proof-of-reserve and activity reporting remain continuously available.
How it works
From reserve to circulation.
Four stages, with the licensed issuer in control of reserves and obligations at every step.

Use cases
Who deploys Q-Stables.
Licensed issuers
Regulated stablecoins
Licensed issuers launch fiat-referenced stablecoins that meet emerging regulatory frameworks, with reserve transparency and controls built in.
Banks
Bank-issued digital money
Banks issue tokenized deposits and fiat-referenced instruments for settlement and payments, secured at the protocol layer.
Payment institutions
Settlement & payments
Regulated payment institutions use stablecoins as a secure, transparent settlement layer across their networks.
