Four major cryptocurrency projects, EtherFi, Lighter, Aerodrome, and Folks Finance, are set to implement significant updates and launches in November. EtherFi has approved a $50 million ETHFI token buyback to stabilize its price, which has fallen over 46% in the past month. Lighter plans to introduce spot trading for BTC and ETH, along with FX perpetuals, in early November. Aerodrome will transition from its MetaDEX02 phase to the development of MetaDEX03, a substantial upgrade to its decentralized exchange. Folks Finance will launch its native FOLKS token on November 6, with 25.4% of the total supply entering circulation.
