New Technology Contract Law and Web 3.0

Technology and Web 3.0 contracts in France and the EU

Tech transactions sit at the seam of contract law, IP law and digital regulation. From SaaS licensing and outsourced development to smart contracts, NFT projects and AI deployment, every digital business needs contracts that hold up commercially, legally and technically.

Five technology contract families we cover

IT contracts. Software development agreements, SaaS terms, B2B licences, application supply, integration, maintenance, hosting, outsourcing. We address SLA, escrow, IP allocation, liability caps, and data clauses adapted to the AI Act and the Data Act.

Smart contracts. Self-executing protocols on blockchain that automate predefined contractual clauses. We help draft the underlying legal agreement, define the on-chain and off-chain split, and anticipate disputes and bug-related liability.

NFT contracts. Co-production, minting, royalty distribution, IP allocation on the underlying work, secondary market royalties, marketplace terms. Aligned with MiCA’s NFT carve-out and CJEU evolving case law.

Technology transfer and licensing. Transfer of know-how, patents, software, biotech assets between innovators and exploiters. Often combined with patent licensing, tax structuring and EU competition law assessment.

Other Web 3.0 contracts. Cryptocurrency-related contracts, blockchain governance documents, DAO charters, virtual land acquisition in metaverses, video game and esports contracts.

FAQ on technology and Web 3.0 contracts

Are smart contracts legally binding in the EU?

Yes, in most cases. A smart contract that meets contract validity conditions (consent, capacity, lawful object, lawful cause) is binding. However, applicable law still governs interpretation and enforcement. The on-chain execution is the technical implementation of the underlying legal agreement.

Does MiCA apply to my NFT project?

MiCA generally excludes NFTs that are truly unique and non-fungible. However, NFT collections with interchangeable characteristics or functioning as financial instruments may fall under MiCA or the EU prospectus regime. A case-by-case legal analysis is essential before launching a collection.

How do I allocate IP in a SaaS contract with a French client?

Three configurations: provider keeps all IP and grants a licence (standard SaaS), provider keeps IP but transfers some specific deliverables, or full transfer of bespoke developments. Each requires precise drafting under Articles L.131-3 and of the French Intellectual Property Code, with particular attention to the formal requirements for assignment of each right by scope, purpose, territory and duration.

What does the AI Act mean for my software contracts?

The AI Act requires cooperation between providers and deployers, transparency on training data, fundamental rights impact assessments (FRIA) where applicable, and conformity assessment. Tech contracts must include cooperation clauses, warranties, indemnities and termination triggers tied to AI Act non-compliance.

Are open source components compatible with a closed-source SaaS contract?

Yes, with care. Permissive licences (MIT, BSD, Apache) are compatible. Strong copyleft (GPL, AGPL) requires careful architecture, especially AGPL which extends copyleft to network use. SaaS contracts must include open source compliance representations and IP indemnification.

Can I use ICC or LCIA arbitration for a French tech contract?

Yes. International arbitration is widely used for cross-border tech contracts. ICC (Paris) and LCIA (London) are popular venues. The arbitration clause must be carefully drafted to ensure enforceability under French law and the New York Convention.
