Closed-Loop Stablecoins
for Regulated Payments

Compliant digital money inside controlled ecosystems - powered by NEXUS

NEXUS Closed-Loop Stablecoins deliver blockchain efficiency with full regulatory control - no public DeFi exposure, no anonymous wallets, no compliance uncertainty. Launch fiat-denominated stablecoins that operate exclusively within your platform, network, or enterprise environment.

Enterprises Fintechs Banks Regulated Platforms

Programmable e-money on blockchain rails

Closed-loop stablecoins are fiat-backed Electronic Money Tokens (EMTs) restricted to a defined, permissioned ecosystem.

Whitelisted Participants

Tokens can only be issued, held, and transferred by whitelisted, KYC-verified participants

No Crypto Exposure

Users do not need to interact with cryptocurrencies or public blockchains

Restricted Circulation

Circulation is restricted - no public DeFi, no permissionless wallets

Programmable e-money, running on blockchain rails - without opening the loop.

Why traditional payment models fall short

Closed-loop stablecoins address structural limitations holding back digital payments in regulated environments.

Compliance Burden

Travel rule regulation, transaction monitoring, AML, CTF, and KYC place growing burdens on payment operations. Closed-loop models centralise compliance at the issuer level.

Micropayment Economics

When transaction costs exceed the payment value itself, pay-per-use services, IoT payments, and micro-settlements become economically impossible with traditional rails.

Localized Currency Limitations

Purpose-bound money and regional payment systems remain cumbersome, lack transparency, and are susceptible to misuse without proper digital controls.

Legacy Escrow Limitations

Complex transactions require costly intermediaries because traditional money lacks programmable logic for conditional execution and automated settlement.

Fintech Infrastructure Gap

Many organisations need regulated wallet-based payment solutions but cannot afford the necessary licensing and infrastructure to build from scratch.

Business Model Constraints

Traditional e-money solutions do not support new business models that require programmable, instant, and zero-fee money movement within ecosystems.

How closed-loop works

Tokens circulate between the Issuer, Service Providers, and Customers inside a permissioned network - with independent oversight from Auditors and reserve safeguarding by Banks.

Control. Compliance. Predictability.

Closed-loop EMTs are purpose-built for governed payment environments.

Full Control

Full control over holders and transactions

Centralized AML/KYC

Centralized AML/KYC enforcement by the issuer

Lower Costs

Lower transaction costs vs card and correspondent banking

Deterministic Finality

Deterministic finality and high performance

Native Controls

Freeze, recover, reverse, redeem - built into the protocol

Governance First

Perfect for environments where governance matters more than permissionless access

Beyond simple transfers

Closed-loop stablecoins are not just digital cash - they are programmable e-money with built-in logic, restrictions, and automation capabilities.

Purpose-Bound Money

Issue digital money programmed for specific contexts - with geographic, merchant-specific, or category restrictions enforced at the protocol level.

Smart Transactions

Enable automated, conditional payments that only execute when predefined conditions are met - replacing costly escrow intermediaries with programmable logic.

Instant Micropayments

Process digital content, IoT services, and micro-settlements profitably with zero-fee transfers - enabling payment models that are uneconomical on traditional rails.

Closed-loop stablecoins blend the familiarity of e-money with the programmability of blockchain - enabling new payment models without requiring users to interact with crypto or manage private keys.

100% fiat-backed. Fully reserved.

Every closed-loop stablecoin is backed 1:1 by fiat currency, held in segregated accounts with regulated banking partners.

1:1 Fiat-Backed

Every token is backed by an equivalent amount of fiat currency in reserve

Segregated Accounts

Reserves held in segregated accounts with regulated banking partners

Redeemable at Par

Token holders can redeem to fiat at par value at any time

Audited Reserves

Regular audits ensure reserve adequacy and transparency

Safer than many cash accounts - with reserves protected by regulatory requirements and institutional safeguards.

Flexible permissioned deployments

NEXUS supports flexible permissioned deployments tailored to specific regulatory and operational requirements.

Private Blockchain

Operated by a single regulated issuer with full sovereignty over the network.

Consortium Blockchain

Operated by multiple regulated institutions sharing governance and validation responsibilities.

Known Validators Only

Known validators and whitelisted wallets only - no anonymous access to the network.

No Anonymous Access

All participants are identified and verified

No Public Contracts

No public smart contract deployment

Core Banking Integration

Direct integration with core banking and treasury systems

Full Auditability

Complete auditability and traceability of all operations

A walled garden for digital money

Closed-loop stablecoins operate inside a walled garden with strict participant controls.

Pre-Approved

Participants must be pre-approved before joining the network

KYC-Verified Wallets

Wallets are issued after full KYC verification

Internal Transactions

Transactions stay within the network boundaries

Complete Oversight

The issuer maintains complete oversight of all activity

Aligned with EU limited network principles (similar to gift cards or loyalty systems), but with blockchain efficiency and programmability.

One issuer. One compliance framework.

In traditional regulated payments, each party often needs to perform KYC on the counterparty. With NEXUS Closed-Loop Stablecoins, this burden is centralised.

Issuer-Verified Participants

All participants are KYC'd by the regulated issuer before gaining access to the ecosystem.

Licensed Obliged Entity

The issuer is an obliged, licensed entity operating under regulatory supervision.

Shared Compliance Framework

Ecosystem participants can rely on the issuer's compliance framework, reducing duplication.

E-Money Directive and MiCA aligned

Traditional E-Money

E-Money Directive (EMD)

Closed-loop stablecoins can operate as traditional electronic money under the European E-Money Directive - providing account-based digital money with established regulatory clarity.

E-Money Token

MiCA (E-Money Token)

When issued on-chain as an Electronic Money Token (EMT), closed-loop stablecoins comply with the Markets in Crypto-Assets Regulation (MiCA) - combining blockchain programmability with regulatory compliance.

Result: Faster onboarding, reduced compliance duplication, and lower operational burden - without compromising regulatory standards.

Example: EURD as a White-Label EMT

EURD is a regulated euro-denominated Electronic Money Token issued by Quantoz Payments under an EMI licence. Built on NEXUS infrastructure, EURD demonstrates how closed-loop EMTs can be deployed in production environments with full governance, reconciliation, and compliance.

For institutions seeking a turnkey digital euro, NEXUS supports white-label EURD deployments, allowing partners to:

  • Operate under their own brand
  • Define issuance, mint, and redeem policies
  • Onboard customers and manage wallets
  • Integrate card rails and payment interfaces
  • Maintain full auditability and regulatory reporting

This approach enables faster time-to-market while preserving issuer control, customer relationships, and regulatory responsibility.
