Encrypted environmental protection startup Ecoterra announced that it has completed a pre-sale round of financing of over US$3.5 million.

The Web3 application it develops allows users to scan the barcodes of the materials they want to recycle. Token incentives are available for recycling plastic bottles, containers, and other reusable materials, and its smart contracts are audited by CertiK. According to data from Ecoterra’s official website, the pre-sale round of financing is expected to end next week
