What is Hashstack?

Hashstack is a secure, permission-less undercollateralized lending platform inclusive to all. You can borrow up to 3 times the collateral without a credit score.
To facilitate loans sustainably, the loan stays within Hashstack. However, users can withdraw up to 70% of the collateral value from the borrowed amount.
Interest rates are calculated by employing the asset utilization ratio and are bound by a range of 2%-20% and 0%-15% for the borrowers and the lenders, respectively.
