A self-custodial exchange DeversiFi (former Ethfinex) relaunched on June 3. DeversiFi 2.0 was built using the StarkWare Layer-2 scaling engine, and optimised using ZK-STARKs and zkRoll-up technology. The exchange is aiming to attract professional traders looking for self-custodial exchange. Nectar (NEC) will remain a native token of the platform. Up to 50% of DeversiFi trading fee revenue will be used to buy back and burn Nectar tokens.
