Stackable DeFi Primitives
USD.AI rebuilds the entire DeFi stack to be oracleless — purpose-built for capital assets, not just money. Six composable primitives. One vertically integrated protocol.
DeFi was built for money. Capital assets need different infrastructure.
Existing DeFi protocols assume liquid, fungible collateral with reliable price feeds. That works for ETH and stablecoins. It doesn't work for GPUs, node licenses, real-world receivables, or any asset where value is earned over time rather than traded on a ticker.
USD.AI replaces oracles with mechanism design. Each primitive in the stack solves one specific problem — tokenization, underwriting, liquidity, yield, redemption — and they compose together into a full lending protocol for the physical world.
Yield. Scale. Redemption.
The legal and tokenization framework that turns physical hardware into enforceable on-chain collateral. UCC Section 7 bailment, bankruptcy-remote SPVs, ERC-721 representations.
Learn about CALIBER →The risk curation process that enables safe scaling. Modular underwriting, amortization schedules, and appraisal pipelines — purpose-built for assets that depreciate and generate cash flows.
Explore FiLo →The liquidity system that turns withdrawal pressure into an orderly, incentive-aligned process. Epoch-based redemption queues with auction-driven priority — no bank runs, no disorderly exits.
Learn about QEV →Six primitives. Three years. One composable stack.
Oracleless lending for low-liquidity assets — NFTs, RWAs, anything without a reliable price feed. Concentrated liquidity positions replace oracles for collateral valuation.
Tradeable yield-bearing tranche positions that rebase on loan repayments. Turns illiquid lending positions into liquid, composable tokens with real-time yield accrual.
Low-latency appraisals and amortization schedules for new asset classes. A modular underwriting toolkit that lets the protocol onboard DePIN hardware, RWAs, and other capital assets at speed.
Strips and isolates yields from productive but illiquid assets like Node Licenses. Separates principal from yield, making locked value accessible and tradeable.
A synthetic dollar backed by AI hardware loans — the culmination of the stack. Depositors earn real yield from GPU financing, not token emissions or recursive leverage.
Structured redemption queue with auction-based priority. Rewards patient capital and creates a secondary market for queue position — turning exit timing into protocol yield.
