ChainCatcher message, the perpetual contract exchange JOJO Exchange developed by DODO co-founder Radar Bear implements ZK proof of funding rates using Brevis's ZK Coprocessor technology. Through Brevis's SDK, JOJO creates ZK proofs based on on-chain perpetual trading and spot price Oracle data, thereby accurately calculating funding rates. Subsequently, the proof is verified on-chain and used to adjust the funding rates for JOJO users.
