# Borrowing Facilities

> Three BTC-denominated borrowing facilities for mining operators.

Mezzamine provides mining operators BTC-denominated capital in the asset they mine, secured by hardware, hashrate, and reserves, with no margin calls in bear markets. Because the fleet is underwritten as collateral, an operator pledges as low as 20% of principal in BTC rather than the 150% a BTC-only facility requires.
