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.

Mandate is an authorization and execution control plane for autonomous financial agents. AI agents can already discover markets, choose trades, and sign actions. The missing layer is proving that a specific action is actually within the authority granted by the human or institution behind that agent. A valid agent signature proves identity; it does not prove permission.
