Oku is a Payment Infastructure that engages with the M3tering Protocol , allowing users to make payments and renew their solar-power utility using Fiat and Crypto Currency. The Aim of Oku is to bridge the gap between users and the M3tering Protocol by providing a payment gateway for users to interacts seemlessly with the m3tering protocol. Essentially, M3tering functions as a token incentivized protocol aimed at stimulating capital investment in solar energy projects. Its primary goal is to facilitate the electrification of underprivileged areas, particularly in Latin America and sub-Saharan Africa. This is achieved by motivating both individuals and institutions to participate as electricity providers, primarily through the implementation of on-site rooftop solar installations and Power Purchase Agreements (PPAs).
