On Zipp since 2026

Etarn is a Web3 project on the BNB Chain that tackles sanitation and agricultural challenges through a "Toilet-to-Earn" framework. The initiative involves deploying smart toilets in urban and rural communities, where human waste is converted into organic fertilizer suitable for farming. Beyond waste processing, Etarn operates digital displays that generate advertising revenue and gathers anonymized data for analytical insights. Verified emission reductions from the overall process are intended to be tokenized as carbon credits, creating an additional revenue stream. A share of these income sources is allocated to ETAN token buybacks and to rewards distributed to users, tying the token to ongoing real-world activity. The project sits within the BNB Chain Ecosystem and is categorized as a DePIN (Decentralized Physical Infrastructure Network) and Quest-to-Earn initiative, combining physical infrastructure with token-based incentives. Its stated objectives include improving public health, supporting environmental sustainability, and building a token economy linked to measurable, on-the-ground operations.
