Why Arch
Why Arch
We specialize in helping long-term Bitcoin holders access liquidity without giving up control.
Here’s how our approach to Bitcoin-backed loans is structured:




No monthly payments
Interest accrues during the loan term. No recurring payments required.

Your Bitcoin is never lent out or reused. It stays securely held with qualified custodians for the life of your loan.




Transparent pricing
Clear, straightforward terms—no hidden fees or surprises.




Flexible structures
Loans can be customized to meet short-term liquidity needs or longer-term financial strategies.




High-trust relationships
We work with individuals, miners, businesses, and family offices who value security, simplicity, and service.




White-glove support
Our team provides personalized, hands-on service throughout the entire loan lifecycle—from onboarding to repayment.
