Oku is a platform designed to enhance user acquisition for the Optimism blockchain by facilitating fiat on- and off-ramping through partnerships with established financial services. By incentivizing new users to deposit capital into Morpho vaults, Oku aims to drive significant total value locked (TVL) growth while ensuring a low risk of sybil exploitation through KYC processes. This initiative not only attracts fresh capital to the Optimism ecosystem but also strengthens its DeFi offerings, positioning it as a competitive player in the blockchain space.
