AntiRugN DAO is the first project to combine voting on decentralised solutions, technology fundamentals and a charity-based function. ✅Signed a strategic partnership with a digital marketing agency - Zo Agency. (ARN) is the tradable, native and liquid token that will contribute to the protocol by filling the DAO Treasury, for distribution to ARN holders and funding of investments in solutions. ✅DApp Released. ✅KYC by SwissShield. ✅Fully audited by InterFi. 🌐Listing on CEX (P2PB2B) 23 August 6PM (UTC).
