According to Mezo and its partners, the Bitcoin-native finance platform has launched Mezo Prime, an institutional product offering yield and lending against held Bitcoin, today. Bullish (NYSE: BLSH) is the launch customer, investing 250 BTC into Mezo and deploying part of its corporate Bitcoin treasury through the product while maintaining custody within its existing compliance infrastructure.

Mezo Prime introduces segregated Bitcoin vaults called "Enclaves," isolated per depositor with no commingling of assets and no rehypothecation. Custody is provided by Anchorage Digital Bank, the first federally chartered digital asset bank in the United States. Bitcoin held in an Enclave can be locked as veBTC to earn protocol fees or used as collateral to mint MUSD, Mezo's Bitcoin-backed stablecoin.
