SanTerris has introduced the S1 token, a utility asset aimed at encouraging sustainable behavior within its Pro Planet ecosystem. Announced from Areuse, Switzerland, the initiative integrates a marketplace, social engagement tools, and a learning engine under a unified incentives framework. The S1 token operates as the core logic of the ecosystem, rewarding users through eco-rewards, project funding, and treasury mechanics based on the 1-1-8 model. The S1 whitepaper, structured in MiCAR Title II format, seeks regulatory clarity to enhance growth and adoption. SanTerris plans a phased expansion, including new payment integrations and social tools, a Pro Planet search engine, and an AI-powered application, all designed to improve user experience and scale incentive systems.
