Blockchain, Payments & Crypto Compliance Development Company in France
France has built one of the EU's most structured on-ramps for crypto-asset businesses through the PSAN (Prestataire de Services sur Actifs Numériques) registration regime, jointly overseen by the Autorité des Marchés Financiers (AMF) and the Autorité de Contrôle Prudentiel et de Résolution (ACPR). Paris has become a magnet for digital-asset trading platforms, payment institutions, and Web3 ventures that want EU market access with a clearly defined national framework rather than a regulatory vacuum. Hurain Technologies builds blockchain infrastructure, exchange and wallet platforms, and payment gateway integrations engineered around the technical expectations PSAN-registered and MiCA-transitioning firms are expected to meet. Our work spans early-stage French crypto startups preparing a PSAN file to established payment institutions modernizing legacy transaction infrastructure.
Overview
Building technology for the France market
France represents a growing market for digital finance and technology infrastructure, where local and international businesses alike need engineering that can adapt to an evolving regulatory and competitive landscape. Hurain Technologies works with businesses in France on Blockchain & Cryptocurrency Development, Payment Gateway & PSP Integration Services, Cybersecurity, AML/KYC & Compliance Engineering and API Integration & Open Banking Engineering, engineering platforms built for engineering discipline that treats security and compliance as part of the build, not an afterthought.
Getting this right in France means building to the specific expectations of local regulators and banking partners from day one, rather than retrofitting compliance onto a platform designed for a different market. Specifically: crypto-asset service providers marketing to French residents generally register as a PSAN with the AMF, with AML/CTF supervision coordinated alongside the ACPR. We build the technical controls this expects — audit logging, access management, and reporting — while jurisdiction-specific licensing and legal strategy should run through qualified local counsel.
There's a second dimension worth flagging too: payment institutions and e-money issuers are licensed and supervised by the ACPR under France's implementation of EU payment services standards. Platforms that ignore this until a partner or regulator asks about it tend to face a far more disruptive retrofit than if it had been designed in from the start.
For businesses building in or expanding into France, the platforms that succeed are the ones engineered for the market's actual regulatory and operational reality, not adapted after the fact from a template built for somewhere else.
Our team approaches every France engagement the same way we'd approach a market we'd worked in a hundred times before: by reading the actual regulatory texts and talking to your compliance function directly, rather than relying on generic assumptions about what "fintech compliance" looks like.
Regulatory Landscape
What operators in France need to know
- Crypto-asset service providers marketing to French residents generally register as a PSAN with the AMF, with AML/CTF supervision coordinated alongside the ACPR.
- Payment institutions and e-money issuers are licensed and supervised by the ACPR under France's implementation of EU payment services standards.
- France's PSAN regime is progressively aligning with the EU-wide MiCA framework, reshaping reporting and custody expectations for registered firms.
- We build the technical controls — KYC/AML workflows, custody security, audit logging — these bodies expect, alongside French-qualified legal and compliance counsel for the registration itself.

What businesses run into in France
Meeting France's regulatory expectations technically
Crypto-asset service providers marketing to French residents generally register as a PSAN with the AMF, with AML/CTF supervision coordinated alongside the ACPR.
Staying current as France's framework evolves
Payment institutions and e-money issuers are licensed and supervised by the ACPR under France's implementation of EU payment services standards.
Scaling past manual processes — reconciliation, compliance review, reporting — that worked at low volume and now consume disproportionate team time
Businesses operating in France often reach a point where the platform that got them to launch isn't the platform that can carry them through their next stage of growth — and retrofitting scale onto a system not designed for it is far more expensive than designing for it from the start.
Finding an engineering partner who understands France specifically
Generic development shops apply the same playbook everywhere, which means someone on your team ends up re-explaining local regulatory and market context on every decision — slowing delivery and increasing the risk that something specific to France gets missed.
How We Solve It
Engineering focus for France businesses
Blockchain & Cryptocurrency Development in France
Many blockchain builds start with insecure, unaudited contracts that fail third-party security review and block funding or listing.
Payment Gateway & PSP Integration Services in France
Poor PSP routing and retry logic silently loses revenue on every failed or declined transaction.
Cybersecurity, AML/KYC & Compliance Engineering in France
Security debt compounds quickly once a platform is handling real transaction volume and regulator scrutiny.
API Integration & Open Banking Engineering in France
Without a proper API gateway and developer portal, every new integration takes weeks of custom engineering.
Production-grade delivery for France teams
Every engagement follows the same discipline regardless of market: formal test coverage, security review before launch, and monitoring from the first day of production traffic — not a lighter process because a market is smaller.
Industries
Sectors we support in France
Banking & Fintech in France
Banks and fintechs are under pressure to open their platforms via APIs, modernize legacy cores, and meet open-banking and AML obligations without disrupting existing operations or customer trust. A common starting point: open banking and partner api programs.
Crypto & Web3 in France
Exchanges, token issuers, and Web3 platforms need production-grade blockchain engineering — not prototype code — to survive audits, scale to real transaction volume, and integrate cleanly with fiat rails. A common starting point: token, coin, and smart contract development.
Payments & PSPs in France
Payment service providers and platforms handling multi-rail, multi-currency transactions need orchestration, reconciliation, and fraud controls that scale across markets without manual overhead. A common starting point: payment orchestration and smart routing.
Enterprise SaaS & Platforms in France
Fast-growing SaaS platforms need to modernize architecture, expose secure partner APIs, and automate operations to keep shipping quickly as customer and data volume scales. A common starting point: monolith-to-microservices migration.
HealthTech & InsurTech in France
Health and insurance platforms manage highly sensitive data under strict regulatory frameworks, requiring secure architecture, automated workflows, and integration with legacy systems of record. A common starting point: secure architecture and data protection engineering.
Real Estate & PropTech in France
Real estate platforms and PropTech operators are digitizing property transactions — from tokenized ownership and fractional investment to automated escrow and payment flows — and need engineering that can handle real money movement and regulatory scrutiny, not just listings software. A common starting point: tokenized property and fractional ownership platforms.
Our Standard
What every France engagement includes
Architecture reviewed for local regulatory fit
Data handling, access control, and audit logging designed against France's specific regulatory expectations before development starts, not retrofitted after a partner review flags a gap.
Built for real transaction volume
Load-tested against realistic France usage patterns rather than a clean demo scenario, so scaling from launch to growth doesn't require an architecture rewrite.
Security review before launch
Internal security review and, for platforms handling meaningful value or sensitive data, independent third-party audit coordination before go-live, not as an afterthought.
Documentation your team can actually use
Architecture decisions, deployment runbooks, and operational documentation handed off in a form your internal team or future hires can work from directly.
