Mezo Launches Mezo Prime Yield Vaults as Bullish Deploys 250 BTC Treasury

Mezo has launched Mezo Prime on April 30, 2026, providing institutional-grade segregated Bitcoin yield vaults custodied by Anchorage Digital Bank, with Bullish as the debut customer deploying 250 BTC (~$19.4M at $77,830.91/BTC). The product, first unveiled April 29, allows idle BTC to earn protocol fees via veBTC locking or serve as collateral for MUSD loans without rehypothecation, targeting over 1M BTC on corporate balance sheets. This development signals growing institutional demand to activate idle Bitcoin, potentially boosting on-chain liquidity and treating BTC as a productive asset amid early-stage adoption.
