Mastercard has joined the Blockchain Security Standards Council as a charter-level member, aiming to help shape security and privacy frameworks for blockchain networks and tokenised assets.
The payments firm joins existing members including Coinbase, Fireblocks and Anchorage Digital, contributing to working groups focused on security and privacy standards.
“Part of my job is to make life difficult for criminals,”
Said Claire Le Gal, Mastercard Senior Vice President.
The council develops audit frameworks and best practices for digital asset ecosystems, with Mastercard expected to bring expertise in fraud prevention, cyber resilience and payments risk management.
The move comes as Mastercard expands blockchain initiatives including its Multi-Token Network and Crypto Credential products, aimed at improving trust and usability in digital asset systems.
Industry participants say fragmented security standards remain a barrier to institutional adoption, with unified frameworks seen as key to accelerating participation from traditional finance.
Mastercard’s involvement signals growing recognition of blockchain as critical infrastructure, as legacy financial firms increasingly seek to shape governance and security across the sector.
