Digital asset trading firm STS Digital said Thursday it has secured $30 million in strategic capital to expand its institutional digital asset derivatives infrastructure.

According to a statement shared with The Block, CMT Digital led the round, with participation from Payward, Strobe Ventures, Arrington Capital, F-Prime, and BitRock Capital. Payward, the financial infrastructure company behind Kraken, reported $2.2 billion in adjusted revenue for 2025 earlier this month.

STS Digital said it will use the fresh capital to scale its institutional-grade spot and options platform, deepen its market-making capabilities, and strengthen its balance sheet and liquidity position.

The funding round comes as crypto derivatives, particularly options, continue to gain traction among institutional clients for hedging, yield strategies, and volatility exposure, according to the firm.

“Digital asset options is the fastest-growing product category within the asset class and the market demands principals with resilient balance sheets, best-in-class execution, and disciplined risk management,” STS Digital CEO Maxime Seiler said in the statement. “This funding allows us to scale with focus and intent, alongside partners who will help shape the next phase of crypto derivatives.”

STS Digital describes itself as a regulated principal trading firm specializing in digital asset derivatives and institutional market access. The company claims to offer clients the ability to trade more than 400 tokens across spot, “vanilla and exotic options,” and structured products through a unified platform spanning UI, API, and voice channels. The firm is regulated by the Bermuda Monetary Authority.

In August 2024, STS Digital acquired Swiss crypto market maker Flovtec. The acquisition integrated Flovtec's trading infrastructure and proprietary algorithms into STS Digital's platform, expanding the firm's market-making capabilities and liquidity solutions, according to a statement at the time.
