EKO Protocol v-1.0

EKO Protocol will be an Arbitrum-based Regenerative Finance (ReFi) loyalty infrastructure that bridges Web2 sustainable commerce into Web3 by transforming traditional cashbacks into asset-backed tokens. Powering the ekonavi.com ecosystem, the protocol will allow users to instantly earn EKO tokens through eco-friendly purchases—such as coffee and organic marketplace baskets. These transactions will also trigger green certifications, natively tracking positive impact directly on-chain. Every EKO token issued will be instantly backed by a stablecoin Floor Price Vault. By delivering immediate utility, verified green metrics, and a guaranteed on-chain redeemable floor price, EKO Protocol will create a friction-free blueprint for driving real-world economic volume straight to the Arbitrum network.
