Key Takeaways
- • Calais Digital Assets, a Singapore-headquartered quantitative hedge fund, became the first institutional client to deploy UBS uMINT (a tokenized USD money market fund) as off-exchange settlement (OES) collateral in live trading operations, executed via Bybit, ByCustody, and DigiFT.
- • The deployment demonstrates capital efficiency gains: uMINT holdings remain yield-bearing while simultaneously serving as trading collateral on Bybit, eliminating the traditional requirement for idle, non-yielding cash collateral at exchanges.
- • The transaction leverages infrastructure established in 2025 through collaboration between Bybit and DigiFT, which created the technical and regulatory framework enabling UBS uMINT to be accepted as institutional trading collateral.
- • This milestone marks the transition from theoretical infrastructure to real-world, institutional-scale execution of tokenized asset collateral arrangements, with custody maintained by ByCustody throughout active trading.
Summary
Calais Digital Assets has achieved a significant institutional adoption milestone by becoming the first quantitative hedge fund to operationalize UBS uMINT as off-exchange settlement collateral in active trading. The transaction, announced June 18, 2026, was executed across an integrated infrastructure spanning Bybit (the world's second-largest cryptocurrency exchange by trading volume and a licensed virtual asset platform operator across multiple jurisdictions), ByCustody (Bybit's institutional custody division), and DigiFT (authorized distributor of the UBS USD Money Market Investment Fund).
The structural innovation addresses a longstanding inefficiency in traditional collateral markets. Under conventional OES arrangements, institutional counterparties must post idle cash or cash equivalents to exchanges—capital that remains undeployed and generates no yield throughout the trading period. By contrast, Calais's deployment allows uMINT holdings to remain in ByCustody's custody while simultaneously functioning as live trading collateral on Bybit, enabling the fund to maintain yield accrual on its collateral position throughout active trading operations. This arrangement enhances capital efficiency without introducing counterparty or custodial risk.
The deployment builds on infrastructure collaboration initiated in 2025 between Bybit and DigiFT, which established both technical integration and regulatory frameworks necessary for uMINT acceptance as institutional collateral. Calais's execution closes the practical gap between theoretical infrastructure design and institutional-scale implementation, demonstrating that yield-bearing tokenized collateral is operationally feasible and compliant across licensed platforms. UBS uMINT, positioned as the first tokenized investment fund launched by UBS Asset Management, now has proven utility within active trading workflows at a major global exchange, signaling broader institutional acceptance of tokenized asset vehicles in professional trading ecosystems.
