Summary
Ketju does not approve sUSDai: it is a share in a private credit fund that lends against GPU hardware, and holders can redeem only through a 30-day queue that may run for several cycles. This verdict covers sUSDai and does not classify base USDai as the same credit claim. USDai is the non-yielding liquid wrapper. sUSDai is a share in a fund that makes non-recourse loans to AI infrastructure operators at 70-80% loan-to-value, secured on GPU hardware. GPU Finance Ltd. is the lender of record. The Cayman-registered USD.AI Foundation runs the protocol, and its core contracts sit on Arbitrum behind a multisig whose signers and timelock the docs do not publish. On 2026-08-14 roughly $261M of $430M in deposits was out in loans, and the only on-demand exit was a $3.76M Curve pool. No loan has defaulted, so none of the collateral protections has been tested. The homepage sells a fully-backed synthetic dollar, while the docs' fine print says sUSDai is not a stablecoin and redemption may not be possible at all. A client who sizes it like cash has mistaken the wrapper for the exposure.
