CALIBER Deep Dive

When we began developing USD.AI, we faced a critical question:

How do you represent real-world infrastructure—like GPUs—onchain in a way that is enforceable, insurable, and programmable?

We weren’t just theorizing. We needed this for ourselves. Our core product depended on the ability to finance compute infrastructure at scale, without relying on weaker workarounds like SPVs, proxies, or custodial lockups.

None of the existing RWA frameworks worked. So we built one. We called it CALIBER.

CALIBER is our legal and technical foundation for infrastructure-backed lending, enabling USD.AI to mint synthetic dollars against real-world assets like GPUs, antennas, and servers, while giving both borrowers and lenders the guarantees they need to operate with confidence.

What is CALIBER

CALIBER stands for: Collateralized Asset Ledger: Insurance, Bailment, Evaluation, and Redemption.

It is a framework we developed with our legal and technical teams to turn physical assets into ERC-721 NFTs that function as legally binding documents of title—under UCC Article 7.

These NFTs are not just jpegs. Whoever holds them has legal rights to the physical asset, including the ability to recover it in the event of default. At the same time, borrowers retain the ability to use the asset through a bailment structure, allowing the hardware to remain online and productive throughout the loan term.

How It Works

The full lifecycle of a CALIBER-backed loan includes several key components:

1. Asset Sale & Tokenization: The borrower sells their hardware to a Tokenizing Agent. That agent mints an ERC-721 NFT governed under UCC Article 7, representing legal title to the asset.

2. Bailment: The borrower signs a bailment agreement that allows them to continue using the hardware while the NFT is posted as collateral. The asset remains operational.

3. Collateralization & Insurance: Once verified and insured, the NFT is posted to mint USDai—a synthetic dollar backed by the real-world asset. Verifications include site inspections, proof of installation, and insurance coverage (fire, theft, etc.).

4. Redemption or Default: If repaid, the borrower gets their asset back. If not, the NFT is auctioned onchain. After a 14-day redemption window, the new holder gains legal ownership of the asset.

Why It’s Different

CALIBER doesn’t rely on SPVs, custodians, or proxy claims. It offers:

• Direct 1:1 legal ownership via NFT
• Onchain enforcement, backed by commercial law
• Insurance against loss, theft, or damage
• Real-world utility for borrowers during the loan
• Onchain liquidation through transparent auctions

Here’s how it compares:

Why It Matters

For lenders, CALIBER offers confidence. Assets on [USD.AI](http://USD.AI) represent real collateral that can be verified, enforced, and recovered. There’s no black box, no SPV risk, and no reliance on unverifiable cash flows.

For borrowers, CALIBER unlocks access to capital without giving up equity or pausing operations. Infrastructure operators can finance their networks while keeping them in operation as well as scale without dilution.

This framework can work with any infrastructure vertical including: energy, wireless, and compute. We believe it sets a new standard for what enforceable, composable RWA tokenization can look like.
