On Superseed, users can use various asset types as collateral to mint and borrow Superseed stablecoins. It introduces two new crypto primitives: Super Collateral and Proof of Repayment. Super Collateral allows borrowers to avoid paying loan interest, while Proof of Repayment programmatically rewards individuals who assist Super Collateral borrowers in repaying their loans.
