Aeroscraper

Aeroscraper is a governance-free, interest-free collateralised debt position protocol. Users lock SEI or INJ on Sei and Injective to open a trove and mint the dollar stablecoin aUSD at a minimum 115% collateral ratio, paying a one-time opening fee instead of accruing interest. The system stays over-collateralised, aUSD is always redeemable for a dollar's worth of collateral, prices come from Pyth oracles, and a vault below its threshold is liquidated. Contracts are immutable after deployment, with no admin keys and parameters fixed at launch.

The low ratio means the same collateral supports more liquidity, and zero interest removes debt growth on long-held positions. The protocol expanded to Archway and Neutron, went live on Injective mainnet on 28 March 2024, and later completed a Beosin audit with a public report, with the code callable from third-party front ends.
