StableDay is a day-long networking and deal-making event focused on stablecoins, digital assets, and blockchain infrastructure. Held as Day II of Proof of Talk 2026 in Paris on June 3, the event brings together banks, issuers, fintechs, corporates, and protocol operators for panels, masterclasses, closed-door roundtables, and structured networking. Rather than introductory content, StableDay targets participants already familiar with stablecoins who are seeking partnership opportunities, integration timelines, and concrete business outcomes. The program features over 120 speakers, predominantly active CEOs and founders, with curated matchmaking designed to facilitate direct conversations between institutional players and crypto infrastructure providers.
