DeFi Mafia Tram Party is a private gathering organized for select participants in the decentralized finance community during ETHMilan. The event takes place on a tram in Milan on the evening of May 22 into the early hours of May 23, 2026, with a strict capacity limit of around fifty people. Access is limited to those who receive direct invitations or are approved through a discreet application process. Boarding and departure details are shared with confirmed attendees ahead of time. The format centers on a shared tram ride rather than formal programming or presentations. Attendees are asked to bring their own beverages, though hosts arrange a baseline supply of drinks for the group. The setting is intended for informal interaction among established figures in DeFi.
