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.

Tanssi lets teams launch a sovereign, EVM-compatible L1 blockchain in minutes using EVM or Substrate templates. Builders retain full control over runtime logic, gas models, governance, and upgrades, while Tanssi handles block production, RPCs, indexing, and network coordination. Launch and iterate on an L1 without maintaining infrastructure.

Shared blockspace helped Web3 scale, but it no longer meets the needs of real-world applications. As payments, trading, RWAs, and user-facing platforms demand predictable execution and control, modular infrastructure enables sovereign L1s with customizable execution, reliable performance, and Ethereum-aligned security, without infrastructure complexity.
