Hong Kong, October 23, 2025 – Cactus Custody, Matrixport’s digital asset custodian, today announced the launch of its Over-the-Counter (OTC) Desk service for institutional clients, through a strategic partnership with Fly Wing Technologies Pte Ltd (“Fly Wing”), a Major Payment Institution licensed by the Monetary Authority of Singapore (MAS) to provide digital payment token (DPT) services for OTC trading. The collaboration delivers a secure, compliant, and transparent fiat settlement solution for institutions, further strengthening Cactus Custody’s mission to build a one-stop digital asset service platform.

This milestone follows Cactus Custody’s recent partnership with Singapore Gulf Bank to enable regulated fiat custody with 24/7 access, marking another step toward bridging traditional finance and Web3.

To access the new service, all Cactus Custody users must complete Fly Wing’s eKYC onboarding process. Unlike crypto exchange-based models, Fly Wing completes OTC transactions via bank transfers, designed to deliver enhanced security, compliance, and transparency. At launch, the Cactus OTC Desk supports USDT/USD and USDC/USD pairs, with more pairs to be introduced progressively.

Driving capital efficiency remains a critical element for institutional Web3 participation. Beyond safeguarding assets with Hardware Security Module (HSM), industry-leading cold storage, and geographically distributed custody strategies, Cactus Custody continues to integrate regulated fiat settlement capabilities through partnerships with regulated financial institutions. These efforts aim to enhance capital efficiency and strengthen institutional trust.

“Building industry-leading security infrastructure and facilitating secure institutional participation in the Web3 ecosystem are core to Cactus Custody’s mission,” said Wendy Jiang, General Manager at Cactus Custody. “Fly Wing’s dedication to security, compliance, and transparency will deepen user trust and accelerate institutional Web3 adoption.”

With the integration of Fly Wing’s OTC services, Cactus Custody is exploring partnerships with additional regulated OTC providers to broaden institutional access and service flexibility.
