QEV, or Queue Extractable Value, is a decentralized liquidity primitive designed to manage redemptions in the USD.AI protocol. Its primary goal is to handle long-dated, illiquid collateral—such as tokenized hardware or DePIN infrastructure loans—using a market-driven mechanism rather than first-come, first-served approaches

FiLo Curator is USD.AI’s foundational scaling lever. It ensures that real-world infrastructure loans can be onboarded at scale while preserving risk alignment and structural protections for all participants.

CALIBER stands for Collateralized Asset Ledger: Insurance, Bailment, Evaluation, and Redemption. It’s the legal and technical backbone of USD.AI that enables the tokenization of physical hardware collateral into verifiable on-chain assets.
