Mezo has launched a decentralized finance (DeFi) protocol focused on Bitcoin, offering BTC-collateralized lending, stablecoin issuance, and an on-chain circular economy. The platform introduces a dual-token system where users can lock BTC to earn veBTC, gaining BTC fees from on-chain activities. Additionally, locking MEZO tokens can enhance BTC returns by up to five times and allow participation in governance. The MEZO token has a total supply of 1 billion, with 40% allocated to the community. Airdrops will be available to users with a history of lending on platforms like Aave, MakerDAO, and Compound. Eligible users can register for the airdrop and pre-deposit at bankfree.mezo.org, with current annualized returns estimated at 34%.
