Tanssi Foundation

EcoCity shows what happens when the L1 renaissance moves from theory to production. Built on Tanssi, EcoCity lets users explore live sovereign L1s and see why teams are choosing dedicated blockspace over shared rollup environments. This campaign invites creators to analyze real infrastructure decisions already shaping payments, trading, gaming, RWAs, and onchain applications.

Vetrii has deployed its sovereign Layer 1 blockchain on Tanssi mainnet to bring the Digital Vehicle Passport into production in Brazil. Built with HOUS3 and designed for national scale, the Tecpar Blockchain enables vehicle tokenization, lifecycle traceability, verified ownership transfers, and regulatory compliance across Brazil’s automotive ecosystem.

Real-world applications across Latin America are moving to sovereign Layer 1 blockchains to support payments, finance, gaming, and public-sector systems. Built on Tanssi, these production networks serve over 200,000 users in Brazil and the region, offering predictable fees, controlled execution, and dedicated infrastructure for real-world workloads.
