Visa, in collaboration with DeFi startup WeFi, has initiated a pilot program to integrate stablecoin payments into traditional card payment systems across Europe, Asia, and Latin America. This initiative aims to enable consumers to use self-custodied stablecoins for card payments, leveraging WeFi's infrastructure to connect DeFi-native assets with Visa's global network. The pilot will initially focus on regulated, fiat-backed stablecoins, with potential expansion to other digital assets pending regulatory approvals and partnerships. WeFi's platform acts as an orchestration layer between decentralized finance and regulated payment systems, emphasizing self-custody options. This approach allows users to maintain control over their assets while accessing traditional payment rails. Visa views this partnership as a progression from its previous stablecoin settlement pilots, which have expanded to nine blockchains and reported significant growth in settlement volumes. The collaboration marks a significant step in bringing stablecoins into consumer-facing payment experiences, potentially transforming the role of card networks and fintechs in the financial ecosystem. The pilot's success could accelerate the integration of DeFi custody models with mainstream payment infrastructures, contingent on regulatory approvals and partnerships with issuing banks.
