Bitcoin infrastructure provider Maestro has launched a Bitcoin-denominated credit market backed by mining economics. The program, Mezzamine, went live in partnership with Sazmining, offering institutional Bitcoin (BTC) holders an annual yield of 8% to 9%.
The offering connects miners seeking capital with institutional BTC holders, creating an onchain credit market. According to Maestro's co-founder and CEO, Marvin Bertin, the platform allows BTC holders to earn and share block rewards with miners.
The credit facility includes bear-market protection features, such as hedging tied to Bitcoin prices and mining-fleet economics, to stabilize performance during downturns. The minimum allocation is $100,000 worth of Bitcoin.
Institutions receive yield funded entirely by mining output, without additional token incentives or leveraged strategies. This reduces liquidation risks for miners, as loans are denominated in Bitcoin, not dollars.

Sazmining, a mining-as-a-service provider, uses hydropower and other carbon-free energy sources. Maestro has seen over 1,500 BTC in borrowing demand from qualified mining operators, including public miners and mid-sized operators.
