Systemic Role within SwissChain Control Architecture Within SwissChain's overall control architecture, Fiat Republic functions as the regulated banking and payments gateway through which SwissChain's operating subsidiaries access fiat currency accounts, payment rails, safeguarding and settlement services for crypto-related flows. Fiat Republic is not a direct customerfacing entity operated by SwissChain but a specialist Electronic Money Institution (EMI) and BankingasaService (BaaS) provider that SwissChain's subsidiaries integrate via API to obtain individual and pooled virtual IBANs, SEPA and Faster Payments connectivity, real-time FX, local payment schemes and treasury services, all designed explicitly for crypto and stablecoin platforms. This design positions Fiat Republic between SwissChain's crypto infrastructure (DFNS custody, SCRYPT execution) and a consortium of "cryptofriendly" banks, enabling subsidiaries to onboard and offboard fiat without relying on ad hoc or unregulated payment service providers. For SwissChain's banking clients and institutional counterparties, Fiat Republic represents a critical proof point: that fiat flows are not handled via improvised arrangements but through a duallicensed, GDPRaligned, safeguardinggoverned EMI whose technical architecture is purposebuilt for crypto businesses. Fiat Republic's platform exposes a single API that aggregates multiple underlying banks and payment networks, so SwissChain's subsidiaries integrate once and gain access to multiple fiat rails without needing to establish direct bilateral banking relationships with each institution. In systemic terms, Fiat Republic sits at the fiattocrypto and cryptotofiat interface: client deposits flow via SEPA/Faster Payments into safeguarded emoney accounts at Fiat Republic, are credited to client balances in real time, and can then be used by the operating subsidiary to purchase crypto assets or to fund stablecoin positions; conversely, when clients liquidate crypto holdings, the fiat proceeds flow through Fiat Republic's rails back to client bank accounts, with full transactionlevel audit trails maintained for AML and regulatory reporting. ## II. Legal Nature, Regulatory Perimeter and Market Positioning Fiat Republic operates through two distinct Electronic Money Institution (EMI) authorizations, which define its legal capacity and regulatory obligations. In the United Kingdom, Fiat Republic Financial Services Ltd is authorised and regulated by the Financial Conduct Authority (FCA) as an emoney institution (firm reference number 901020), enabling it to issue electronic money and provide payment services including money remittance, acquiring and executing payment transactions, but not to take deposits or lend. UK EMI regulation requires safeguarding of customer funds (segregation from the firm's own assets and placement with safeguarding banks or investment in secure liquid assets), compliance with AML/CFT obligations, governance and operationalresilience standards. In the Netherlands, Fiat Republic Financial Services B.V. holds a full EMI licence from De Nederlandsche Bank (DNB), allowing it to issue emoney and provide payment services across the European Economic Area under the EU's EMoney Directive, with similar safeguarding and AML/CFT requirements. This dual UK-EU licensing is material for SwissChain: it enables subsidiaries to route EUR, GBP and USD flows through entities that are supervised under GDPRaligned regimes and subject to prudential AML/safeguarding frameworks, rather than relying on unregulated PSPs or offshore arrangements. Fiat Republic positions itself explicitly as a "cryptofocused" EMI and BaaS provider, founded in London with the mission to "bring banking to web3" by aggregating cryptofriendly banks and providing pooled and individual virtual IBANs, SEPA and Faster Payments, local rails and real-time FX via a single developerfriendly API. Public materials describe Fiat Republic as purposebuilt for crypto platforms, with a "compliancefirst" data architecture that provides partner banks with real-time feeds of fiattocrypto transaction data to support their AML and riskassessment obligations. According to publicly available information, Fiat Republic serves numerous crypto and fintech clients and has processed significant transaction volume; it maintains strategic relationships with a consortium of cryptofriendly banks and payment partners, enabling its clients to access liquidity, settlement and treasury services without needing to navigate individual bank approvals and fragmented integration efforts. Fiat Republic's acquisition of Paybase Limited enabled it to become an EMI in the UK, and subsequent fundraising (including a reported USD 7 million seed extension in 2023 and total funding in excess of USD 10 million) and regulatory expansion (acquisition of Dutch EMI licence in 2025) indicate sustained market traction and institutional backing. ## III. Certification and Assurance Framework Fiat Republic's regulatory framework is anchored in its FCA and DNB emoney licences, which impose structured safeguarding, governance, AML and operationalrisk requirements comparable in scope to other EMIs in the UK and Netherlands. UK EMI regulation requires that customer funds be safeguarded either by depositing them in segregated accounts with authorised credit institutions or by investing them in secure, liquid, lowrisk assets approved by the FCA; Fiat Republic must perform daily safeguarding reconciliations and ensure that, in the event of insolvency, customer funds are protected and swiftly returned. Similarly, Dutch EMI regulation under DNB supervision requires safeguarding in segregated accounts or approved investments, with governance and risk management processes subject to regulatory review. Fiat Republic's own blog and public materials emphasise "safeguarding in crypto," explaining how emoney and MiCARstyle frameworks require that customer fiat and emoney tokens are held in safeguarded accounts with regulated banks, directly addressing the concern that crypto platforms may commingle customer fiat with corporate treasury or operational funds. From a dataprotection standpoint, Fiat Republic explicitly aligns with EU GDPR and UK GDPR requirements, given its UK and Dutch operations and the cross-border nature of its client base. Public materials describe a "compliancefirst data model" whereby Fiat Republic provides banks with a real-time feed of fiattocrypto transaction data, allowing banks to monitor flows, apply AML screening and conduct risk assessments, while giving crypto platforms full audit trails for all fiat movements. This architecture is designed to reduce the information asymmetry that traditionally causes banks to derisk crypto clients: rather than treating crypto-related accounts as opaque, Fiat Republic structures data flows so that banks see originator, beneficiary, purpose and risk signals for each transaction. External reviews and partner announcements note that Fiat Republic holds EMI licences in the UK and Netherlands and emphasise its role in helping clients meet AML and financialcrime requirements, with specific mention of transaction monitoring, KYC/AML tooling and regulatory reporting capabilities. While Fiat Republic does not publicly list ISO or SOC certifications, the regulatory framework (FCA and DNB EMI supervision), safeguarding obligations and explicit AML/datasecurity focus together form a sufficient baseline for institutional due diligence, to be supplemented by underNDA audit reports and vendorrisk reviews in SwissChain's governance framework. ## IV. Core Technical Architecture and Control Surface Technically, Fiat Republic exposes a single REST API through which SwissChain's operating subsidiaries can provision individual and pooled virtual IBANs in multiple currencies (EUR, GBP, USD and other supported currencies), initiate and receive payments via local and international schemes (SEPA, SEPA Instant, UK Faster Payments, CHAPS, and additional schemes as added), execute real-time FX transactions, and manage treasury operations. Individual virtual IBANs allow each enduser or corporate client to receive a unique IBAN attributed to their identity, enabling automated reconciliation of incoming payments without manual matching; pooled virtual IBANs provide a single IBAN for collecting payments from multiple users, with transaction references used for reconciliation, which is suitable for certain treasury and operational workflows. Both models support real-time crediting and 24/7 automated processing, reducing the delays and manual intervention typical of traditional correspondentbanking arrangements. Fiat Republic's architecture is built around what it describes as a "compliancedriven" data layer that captures more transaction metadata than standard payment processors, providing full visibility into payment flows for both SwissChain's internal compliance teams and partner banks. Each payment transaction carries originator and beneficiary identifiers, payment purpose, risk flags and related cryptotransaction linkage where applicable, enabling detailed transaction monitoring, sanctions screening and audittrail generation. The platform supports real-time collections and payouts, allowing SwissChain's subsidiaries to initiate fiat deposits and withdrawals on behalf of clients with nearinstant settlement, and offers real-time FX via Request For Quote (RFQ) flows integrated directly into payment workflows, so that currency conversions are executed at market rates without batching delays. Fiat Republic further operates an internal settlement network called "EagleNet," which enables instant transfers of fiat between Fiat Republic's consortium members, allowing SwissChain and other clients to move liquidity rapidly across accounts without waiting for external bank clearing. In addition to standard collections and payouts, Fiat Republic's API supports businessoriented payment functionalities including invoice payments, bill pay and extended remittance. According to public documentation and service descriptions, business clients can use Fiat Republic's platform to pay invoices and bills to suppliers, vendors and contractors, with support for recurring payments, multiinvoice payments (extended remittance allowing a single payment to cover multiple invoices from one vendor) and scheduled payments. This capability is relevant for SwissChain's subsidiaries and their corporate clients: it allows fiat treasury operations—such as paying operational expenses, contractor invoices, supplier bills or recurring service fees—to be managed through the same BaaS API that handles customer deposits and withdrawals, providing unified reconciliation and audit trails across all fiat activity. The platform's reporting and dashboard tools enable real-time monitoring of balances, transaction status, failed payments and audit logs, with account statements and transaction exports available for all linked virtual accounts, supporting both operational treasury management and regulatory reporting requirements. ## V. Risk Mitigation Mechanics and Residual Risk For SwissChain and its operating subsidiaries, Fiat Republic mitigates several structural banking risks that have historically challenged crypto platforms. First, the use of a duallicensed EMI (FCA in UK, DNB in Netherlands) reduces jurisdictional and regulatory risk: fiat accounts and payment services are provided within supervised frameworks that impose safeguarding, governance and AML standards, rather than via unregulated PSPs or offshore arrangements that may carry reputational or legal risk. Second, Fiat Republic's aggregation of multiple cryptofriendly banks behind a single API reduces singlebank dependency and operational fragility; if one underlying bank tightens its crypto risk appetite or exits the sector, Fiat Republic can route flows through alternative banks within its consortium without requiring SwissChain's subsidiaries to reintegrate or reonboard, thereby improving continuity and resilience. Third, Fiat Republic's compliancefirst data architecture and real-time transaction visibility reduce AML and sanctions risk by making it easier for both SwissChain's compliance teams and partner banks to monitor flows, detect anomalies and align with evolving AML/MiCA expectations. The platform's support for detailed transaction metadata, audit trails and regulatory reporting enables SwissChain to demonstrate to auditors and regulators that fiattocrypto and cryptotofiat flows are subject to structured controls rather than opaque or ad hoc processes. Fourth, the ability to issue individual virtual IBANs for endusers and pooled IBANs for treasury operations supports automated reconciliation, reduces manual errors and accelerates fiat settlement, which is directly relevant for client experience and operational efficiency. Residual risks nonetheless include concentration risk at the EMI layer: Fiat Republic becomes a critical intermediary for fiat flows, and service disruptions, technical outages or regulatory actions affecting Fiat Republic could materially impact SwissChain's ability to process client deposits and withdrawals. Additionally, Fiat Republic's service quality and risk appetite are influenced by its underlying bank consortium; if those banks tighten their crypto policies or reduce service levels, Fiat Republic may face constraints that flow through to its clients. Public reviews of BaaS providers note that smaller platforms may find the compliance requirements demanding and that service quality can vary based on underlying bank relationships. Further, while Fiat Republic's EMI licences impose safeguarding obligations, the protection of customer funds in the event of insolvency or operational failure depends on the correct implementation of segregation and safeguarding processes, which must be verified through periodic vendorrisk assessments, auditreport reviews under NDA and documented contingency planning (such as alternative banking rails, secondary EMIs or direct bank relationships where required). ## VI. Integration with SwissChain Stack and Control Flows In SwissChain's target operating model, Fiat Republic is integrated at the fiat onboarding and offboarding layer, used by operating subsidiaries and, where appropriate, exposed to corporate clients for treasury and invoicepayment functionalities. On the inbound side, client funds flow from external bank accounts via SEPA, Faster Payments or other supported rails into individual or pooled virtual IBANs provided by Fiat Republic; these funds are safeguarded under EMI rules and credited to client balances in SwissChain's subsidiaries' systems in real time, with transaction metadata captured for AML screening and audit trails. Before fiat is credited, clients have already passed identity verification, KYC/KYB and sanctions screening via Sumsub, ensuring that only compliant users can access fiat services. Once credited, the fiat can be used by the client to purchase crypto assets (executed via SCRYPT or internal matching engines), fund stablecoin positions or remain in fiat balances for future use. On the outbound side, when clients liquidate crypto holdings or withdraw fiat, SwissChain's subsidiaries initiate payout instructions via Fiat Republic's API, which executes the payment to the client's external bank account via the appropriate rail (SEPA, Faster Payments, etc.), with full compliance checks and transaction logging. For corporate clients and internal treasury operations, SwissChain's subsidiaries can leverage Fiat Republic's invoicepayment and billpay functionalities to pay operational expenses, contractor invoices, supplier bills and recurring service fees, with support for scheduled payments, recurring payments and multiinvoice remittance. This consolidates fiat treasury management into a single BaaS platform, providing unified reconciliation, audit trails and reporting across all fiat activity, and reducing reliance on multiple banking relationships and manual payment processes. For banking clients evaluating SwissChain as a counterparty or infrastructure partner, this integration demonstrates that: - Fiat rails are operated under FCA and DNB supervision, connected to multiple regulated banks. - Transaction data is structured, auditable and shareable, easing correspondentbank AML expectations. - Client fiat is safeguarded under EMI rules; SwissChain's subsidiaries do not take deposits or commingle customer funds with corporate treasury. - Treasury operations, invoice payments and bill pay are executed through the same regulated API, providing comprehensive fiatflow management within a single governance framework. ## VII. Auditability, Supervisory Defensibility and Strategic Implications Fiat Republic materially enhances the auditability and supervisory defensibility of SwissChain's fiatrelated operations. The platform's compliancefirst architecture, detailed transaction metadata and real-time audit trails allow SwissChain's subsidiaries to trace every fiat deposit, withdrawal, invoice payment and treasury movement from initiation through to settlement, with full visibility into originator, beneficiary, payment purpose and related cryptotransaction linkage where applicable. For external auditors and regulators, this means that fiat flows can be reconciled against crypto transactions, AML screening results and client identities, providing comprehensive evidence that fiattocrypto and cryptotofiat operations are conducted under structured controls and supervised arrangements. The ability to generate account statements, transaction exports and compliance reports for all linked virtual IBANs supports both internal governance and regulatory reporting requirements, while Fiat Republic's safeguarding obligations under FCA and DNB supervision provide assurance that customer funds are protected and segregated in the event of operational disruptions or insolvency scenarios. Strategically, positioning Fiat Republic as the central banking and payments infrastructure partner, supported by FCA and DNB EMI licences, safeguarding frameworks, GDPR alignment and a cryptofocused BaaS architecture, allows SwissChain to articulate a coherent institutional narrative to banks, listing venues and investors: that its fiat operations are not improvised or conducted via unregulated PSPs, but are implemented through a duallicensed, compliancedriven EMI that aggregates multiple cryptofriendly banks and provides institutionalgrade payment rails, safeguarding and treasury services. The reported metrics—multijurisdiction EMI licences, significant transaction volume, strategic fundraising and regulatory expansion into the Netherlands—support the argument that Fiat Republic is a mature, productionscale BaaS provider designed specifically for the crypto sector, rather than an experimental or niche service. At the same time, SwissChain's vendorrisk framework must explicitly document that Fiat Republic is classified as a critical outsourced function, with formal SLAs, periodic performance and compliance reviews, scenario testing of fiatflow continuity and documented contingency plans (such as alternative banking rails or secondary EMIs) to mitigate concentration risk. Managed in this way, Fiat Republic can be positioned to bank boards, listing committees, auditors and regulators as a deliberate, riskreducing infrastructure choice that materially strengthens SwissChain's fiat connectivity, safeguarding posture and banking defensibility, demonstrating that SwissChain's operating subsidiaries surround their crypto infrastructure with regulated, compliancedriven partners at every critical interface—DFNS for custody, SCRYPT for execution, Sumsub/Notabene for AML and Travel Rule, and Fiat Republic for banking and fiat payments. This integrated architecture supports SwissChain's strategic positioning not as a crypto platform seeking to bypass traditional finance, but as a technology holding enabling its subsidiaries to integrate with the regulated financial system at the highest available standards.
