Its base token, USDai, is backed one for one by PayPal's PYUSD: on Arbitrum, the PYUSD reserve matched the USDai supply AltStreet counted at the pin to the cent. The yield token, sUSDai, is where the risk sits: on November 10, 2026, 40% of its $441.6 million was GPU loans, 29% was one $128.9 million escrow for a deal not yet funded, which HIVE Digital's filings indicate is its BUZZ Alpha Cloud GPU cluster, and 30% was cash in the vault. The loans are on chain and match the published book, and no default has been recorded on chain. The advertised 7.00% is a target supported by a foundation reserve, and four operational Safes share the same three signer addresses. AltStreet score: 39.6 (C-), scored November 10, 2026. Method: https://altstreet.investments/platforms | Field | Value | | --- | --- | | Platform | USD.AI | | What it is | On-Chain Credit: a PYUSD-Backed Base Token and a Yield Vault That Lends to GPU Operators | | Asset class | Secured loans to AI compute operators (GPU servers as collateral), held through an on-chain vault token | | Website | usd.ai | | Review first published | November 10, 2026 | | Last updated | November 10, 2026 | | AltStreet relationship | None: no affiliate, sponsorship or partnership | ## The short version USD.AI has two tokens. USDai is a non-yielding dollar token minted against PYUSD and redeemable for it one for one. sUSDai is what you get by staking USDai: a vault token whose value rises as GPU operators pay interest on loans the vault has made, plus a PayPal incentive on idle PYUSD. Three questions frame it. What backs it: USDai, fully, as far as the chain shows. On Arbitrum the USDai contract held 157,551,404.94 PYUSD against the 157,551,404.92 USDai AltStreet counted at the pin (the hub's supply plus the amount it records as bridged to other chains). sUSDai is different. Of its $441.6 million net asset value, $134.4 million (30.4%) is USDai sitting in the vault; $176.6 million (40.0%) is principal on 21 loans to GPU operators; and $128.9 million (29.2%) is escrow for one British Columbia deal that has not been drawn, which HIVE Digital's filings indicate is a $128.9 million facility to its subsidiary BUZZ Alpha Cloud. The chain proves the loans were made, are being repaid, and match the site's book to within 1 USDai on 20 of 21. It cannot show the servers, the borrowers' companies or the escrow account. What a holder earns and can take out: the deposit share price grew 7.32% over the past year, and redemptions are paid monthly, first in first out, from cash in the vault, at the lower redemption share price. Every window since January 2026 was paid in full within 1.4 days, including $118 million on November 1. The advertised 7.00% net APY is a target the CHIP Foundation supports from a reserve; the reported net run rate on November 10 was 6.78%. Who controls it: four operational Safes (admin, upgrade, strategy and pause) share the same three signer addresses. The upgrade Safe can replace the loan and escrow contracts with no delay, and did five times between July and October 2026. - **30.4%** Share of sUSDai's $441.6M NAV held on chain as PYUSD-backed USDai at the pin; 40.0% is loan principal and 29.2% is escrow whose cash has left the chain (AltStreet chain reads, November 10, 2026). - **$128.9M** Escrow for one GB200 deal in British Columbia, 29.2% of NAV, listed on the site as 'PO Placed' with nothing drawn. HIVE Digital's 10-Q describes a $128.9M, 9%, three-year GB200 facility for its subsidiary BUZZ Alpha Cloud, with about $125.4M going into third-party escrow after a 1.5% agent fee: a strong match, not confirmed by either company. - **0** Defaults recorded on chain: no loan marked breached, liquidated or written down on either loan router since December 2025; 23 loans repaid in full and 21 active, all 21 matching the site's book by borrower and 20 of 21 by balance within 1 USDai. - **7.00% vs 6.78%** The reserve-supported target ('Net APY (CHR)') vs the reported net run rate on November 10, 2026; the gap is a top-up from a CHIP Foundation reserve that the site says 'is not a guaranteed minimum'. - **1.4 days** Longest time after a 30-day boundary before a redemption window was paid in full, across every window since January 2026 (118.0M USDai on November 1). - **3 signers** Four operational Safes (admin, upgrade, strategy and pause) share the same three signer addresses, at thresholds of 3 of 3, 3 of 3, 3 of 4 and 2 of 3; the upgrade Safe can replace the loan router and escrow contracts immediately. Data note: Chain figures are AltStreet's read-only RPC reads at the pinned blocks. The loan book, TVL, APY and history are USD.AI's own API figures, unaudited. No USD.AI entity publishes audited financial statements; the only third-party report on the loans is an agreed-upon procedures snapshot of 13 loans with no opinion. A chain read proves balances and payments recorded on chain, not the servers, the borrowers' finances or off-chain escrow. ## Key figures | Figure | What it is | Context | | --- | --- | --- | | 30.4% | Most of the vault is loans and escrow whose collateral and cash sit off chain; the chain shows the balances and payments. | Share of sUSDai's $441.6M NAV held on chain as PYUSD-backed USDai at the pin. 40.0% is loan principal and 29.2% is escrow for one undrawn deal. | | 0 | Defaults recorded on chain: no breach, liquidation or write-down on either loan router. | 23 loans repaid; 21 active, all matching the site's book, 20 of 21 within 1 USDai. | | 6.78% | Reported net run rate on November 10, 2026, below the 7.00% reserve-supported target. | Deposit share price up 7.32% over 12 months; withdrawals settle at the redemption share price. | | 3 | Signer addresses shared by the admin, upgrade, strategy and pause Safes. | The upgrade Safe can replace the loan and escrow contracts with no delay. | ## Verdict USD.AI's base token is backed by a PYUSD reserve on Arbitrum that matched its supply at the pin, and its loan book is visible on chain, matches what the site publishes, and has no default recorded on chain. What a sUSDai holder relies on beyond that is USD.AI itself: borrowers known only by wallet, a $128.9 million escrow for one undrawn deal (likely HIVE Digital's BUZZ Alpha Cloud), no audit, a headline yield that is a reserve-supported target, and Safes signed by the same three addresses that can change the loan and escrow contracts without notice. **Best for** - Stablecoin holders who want GPU-credit yield, can check positions on chain, and accept monthly redemption and concentrated control. **Look elsewhere if** - You need instant redemption at NAV. - You need audited statements or a regulated issuer. - You are not comfortable with Safes signed by the same three addresses controlling the vault's accounting contracts. **Strengths** - USDai's Arbitrum PYUSD reserve matched its supply at the pin, to the cent. - Every active loan visible on chain and matching the site; no default recorded on chain. - Every monthly redemption window since January 2026 paid in full within 1.4 days. **Limitations** - 29.2% of NAV in escrow for one undrawn deal. - No audit; one narrow agreed-upon procedures report. - Headline 7.00% is a reserve-supported target, above the 6.78% reported run rate. - Four operational Safes share three signer addresses; immediate upgrades of the loan and escrow contracts. ## Who it fits | Investor | Fit | Why | | --- | --- | --- | | Stablecoin holders seeking a GPU-credit yield who can read the chain | neutral | | | Holders who need to exit on demand | poor-fit | | | Investors who need audited statements or a regulated issuer | poor-fit | | ## Questions **Is USD.AI legit?** USD.AI is a real protocol whose USDai AltStreet found matched by a PYUSD reserve on Arbitrum at the pin, and whose loans are recorded on chain and match the published book, with no default recorded on chain. AltStreet located no regulator action or lawsuit naming it. What rests on USD.AI's word: the borrowers (known only by wallet), the servers and escrow, and its entities, none of which publish audited statements. **What backs sUSDai?** On November 10, 2026: 30.4% USDai held in the vault (backed by PYUSD), 40.0% principal on 21 GPU loans, and 29.2% escrow for one British Columbia deal not yet drawn, which HIVE Digital's filings indicate is its BUZZ Alpha Cloud cluster. Holders have no direct claim on a specific borrower or GPU. **Is the 7% yield real?** Three figures measure different things. 7.00% is a target the CHIP Foundation supports from a reserve, which the site says is not guaranteed. 6.78% is the reported net run rate on November 10, 2026. 7.32% is how much the deposit share price grew over the past year on chain. USD.AI measures its support on the deposit share price, but withdrawals settle at the redemption share price, which grew 5.43% annualized over the past 30 days. **How do I get my money out of sUSDai?** Request redemption; requests are paid first in first out at 30-day boundaries from cash in the vault. Every window since January 2026 was paid in full within 1.4 days. You can also sell sUSDai on Pendle, Fluid, Morpho, Curve or Euler. **Can US investors use USD.AI?** The site says it is not directed at US residents, but the Terms have no US-person exclusion and minting, redemption and staking need no KYC. The tokens are not registered with any regulator. **Who controls USD.AI?** Four operational Safes (admin, upgrade, strategy and pause) share the same three signer addresses; chain data shows the addresses and thresholds, not who holds them. The upgrade Safe can change the USDai and sUSDai contracts after a 48-hour timelock and the loan and escrow contracts immediately. The CHIP governance token does not control any protocol contract. ## Evidence appendix Platform website captured November 10, 2026.
