GDPR Compliance for Crypto and Web3 Companies
GDPR compliance guide for crypto exchanges, DeFi protocols, NFT marketplaces, and Web3 companies outside the EU. EU Rep from EUR 490/yr.
Crypto, blockchain, and Web3 companies often mistakenly believe that pseudonymity or decentralisation exempts them from GDPR. They don’t. If your crypto exchange, DeFi platform, NFT marketplace, or blockchain project processes EU personal data — and most of them do — GDPR applies, and Article 27 requires an EU Representative.
Common Myths in Crypto GDPR
“Blockchain is anonymous, so GDPR doesn’t apply.” Blockchain transactions are pseudonymous, not anonymous. When combined with KYC data, IP addresses, wallet activity, and exchange records, user identities can often be established. This constitutes personal data under Article 4(1).
“DAOs are decentralised and have no legal entity.” Even if a DAO has no formal registration, its operators and contributors processing EU personal data are data controllers under GDPR and need an EU Representative.
Which Crypto Activities Trigger GDPR?
KYC/AML Data Collection
Most regulated crypto exchanges and platforms require identity verification (passport copies, proof of address, selfies). This is some of the most sensitive personal data and clearly triggers all GDPR obligations.
Wallet Address Tracking
If your platform tracks wallet activity, links wallets to IP addresses, or analyses transaction patterns, you are profiling EU data subjects (Article 22).
NFT Marketplaces
Marketplaces with EU users process wallet addresses, email contacts, transaction histories, and often KYC data. Related marketplace guide →
Custodial vs Non-Custodial
Custodial wallets and exchanges have clear GDPR obligations as data controllers. Non-custodial platforms may have reduced but not zero obligations — particularly regarding KYC data and user support.
MiCA and GDPR
The EU’s Markets in Crypto-Assets Regulation (MiCA) adds regulatory layers but does not replace GDPR. MiCA regulates the crypto asset itself; GDPR regulates personal data processing. Both apply in parallel.
3-Step Compliance
- Appoint EU Shield as your EU Representative
- Document on-chain/off-chain data processing — ROPA covering both
- Establish deletion mechanisms — reconcile blockchain immutability with GDPR Article 17 right to erasure
