The facility provides short-term credit specifically designed to support USD.AI’s three-year, monthly amortizing loans. By borrowing against sUSDai, the firm avoids the inefficiency of holding stagnant capital, ensuring a higher percentage of the pool remains actively deployed. This arrangement marks a deepening of the existing relationship between the two entities, following a similar $100 million agreement previously established with Bullish.

Kiril Nikolov, co-founder of K3 Capital, described the deal as a targeted response to market-structure inefficiencies. For K3, the initiative functions as a service for vetted protocols rather than a standalone transaction. David Choi, CEO of Permian Labs, the developer behind USD.AI, noted that the on-chain credit structure provides the necessary agility to support new product launches and broader platform growth as they continue to scale their AI infrastructure financing services.
