The move aligns with Europe’s MiCA framework amid rising tokenization adoption.
Spain has taken a decisive step toward modernizing its digital asset oversight. The Ministry of the Interior has appointed Prosegur Crypto, the institutional custody arm of Prosegur Cash, to manage and safeguard crypto assets seized by the country’s State Security Forces and Corps (FCSE).
The agreement gives Prosegur Crypto exclusive responsibility for registering, tracing, and preserving seized digital evidence, ensuring transparency and compliance under Spanish law. The company will also handle the conversion of crypto into fiat currency when required by judicial authorities, a process previously fragmented across agencies.
Secure custody for tokenized evidence
According to the announcement, Prosegur Crypto’s custody model combines physical vault infrastructure with military-grade encryption to store private keys and prevent tampering. The firm’s systems operate without direct internet access, allowing blockchain transactions to be executed in a controlled offline environment.
“This partnership shows that our security and operational systems meet the standards public institutions now demand,” said José Ángel Fernández Freire, CEO of Prosegur Crypto.
The infrastructure also enables real-time audits and evidence preservation, critical for criminal cases involving tokenized or decentralized assets.
Spain joins Europe’s regulated crypto pivot
The move reflects Spain’s broader effort to align with the EU’s Markets in Crypto-Assets (MiCA) framework, which requires custodians and service providers to meet strict security and compliance standards.
It comes as traditional banks in Spain and across Europe enter the crypto custody market, including BBVA’s new partnership with Ripple to provide digital asset services to retail clients.
At the same time, tokenization continues to expand rapidly. Data from Dune and RWA.xyz shows that tokenized real-world assets (RWAs) have surged over 224% since 2024, surpassing $300B in total value.
By integrating crypto custody into its law enforcement framework, Spain is signaling that digital assets have moved from the financial periphery to the regulatory core. The Interior Ministry’s decision marks one of the first national examples of institutional-grade blockchain security being adopted for public administration.
As Europe tightens its crypto rules, Spain’s model could set the standard for governments managing seized tokens with the same rigor as traditional assets.
