币界网报道：USD.AI has launched a dual-token USDai/sUSDai system, which aims to convert AI hardware and DePIN assets into liquid capital. USDai is a low-risk stablecoin that is collateralized by government bonds to provide liquidity, while sUSDai invests in AI infrastructure loans to earn returns. The project uses the CALIBER framework to ensure asset security, hosts hardware collateral in the form of NFTs, and introduces the QEV auction mechanism to manage redemption liquidity, with a blind auction every month to determine the priority redemption order. The project is currently in the Arbitrum beta stage and plans to expand to more blockchains such as the Ethereum mainnet in the future. This model attempts to solve the financing problem of AI infrastructure, but attention should be paid to the 30-day redemption cycle and early protocol risks.
