Ricardo Filipe
Founder & CEO at Luso Digital Assets
About
Ricardo Filipe is the founder and CEO of Luso Digital Assets, a registered Portuguese crypto-asset broker transitioning to a fully licensed Crypto-Asset Service Provider (CASP) under the European MiCA regulation. His work focuses on building a secure, compliant bridge between traditional finance and the regulated digital asset economy.
Holding a Master’s degree in Computer Science and Engineering from Instituto Superior Técnico (IST) and having served as a researcher in Distributed Systems at INESC-ID, he brings deep scientific rigor to financial infrastructure. This background in fault-tolerant networks allows him to architect and evaluate digital asset systems based on cryptographic soundness rather than market hype.
At Luso Digital Assets, he leads mission-critical operations including cross-border B2B stablecoin settlement, crypto-backed real estate transactions, and institutional-grade Multi-Party Computation (MPC) custody. Every service is engineered in strict alignment with European MiCA and DORA frameworks, while laying the groundwork for Real-World Asset (RWA) tokenization.
On x078.com, he writes about European digital asset regulation, institutional blockchain infrastructure, cryptographic custody, and the enterprise adoption of regulated Web3 systems.
