Stablecoin Day is a one-day event inside NFC Summit 2026, taking place on June 5 at Unicorn Factory Lisboa in Lisbon. It brings together web3-native communities, fintech founders, protocol teams, institutional players, researchers, and policymakers for a day of focused dialogue on stablecoins, bridging the builders and the financial actors building the supporting infrastructure. The program includes talks, panels, and conversations on infrastructure, regulation, adoption, and real-world use cases. The event aims to foster collaboration between those experimenting with new economic models and the traditional financial players building the rails that enable them.
