Copper Named Custodian for Tharimmune, Inc. Canton Coin Treasury Strategy

• Copper to integrate ClearLoop, its institutional-grade collateral management solution, with the Canton Network
• Announcement follows Tharimmune’s $545 million private placement for Canton Coin digital asset treasury strategy
• Copper’s role as custodian and infrastructure partner for Tharimmune comes amidst surging institutional engagement with the Canton Network, which now processes over 500,000 transactions daily.

TUESDAY 18 NOVEMBER 2025 - Switzerland – Copper, a leading provider of digital asset custody and collateral management for institutional investors, today announced its role as a custodian for Tharimmune, Inc., a digital asset treasury (DAT) company with a clinical biotech arm.

This announcement follows Tharimmune’s closing of a $545 million private placement, which created the first publicly traded company to leverage Canton Coin and support the Canton Network to advance institutional blockchain adoption and the digitization of financial markets. Copper is a strategic investor and infrastructure partner for Tharimmune’s DAT strategy.

Addressing a critical need for private blockchain transactions

Significant investment in Tharimmune’s DAT signals the surge in institutional demand for secure, permissioned blockchain infrastructure enabled by the Canton Network.

This trend signals a new phase in on-chain finance, where privacy and regulatory compliance are paramount for large-scale participants. This surge in demand is validated by rapid institutional adoption. Major institutions including Goldman Sachs, Broadridge, and Versana, with backers such as JPMorgan, Citi, and Bank of America are not merely deploying applications on Canton but are clearing and settling assets at a scale of trillions of dollars within just over a year since launch.

In an economy rapidly moving toward tokenization, the need for private transactions has grown exponentially, to protect participants from front-running and support efficient market conditions. Dynamics already evident in blockchains show how publicly visible transfers fuel unnecessary volatility, as routine transfers risk being mistaken for trading signals. The growing preference for private blockchain transactions also illustrates why public networks like Ethereum are racing to implement new privacy features to address these concerns.

Canton and Copper partner to build institutional collateral networks

Copper’s selection as custodian for a DAT like Tharimmune underscores its role at the heart of institutional asset security and collateral management within the Canton Network. Copper is evolving its flagship ClearLoop collateral management product to leverage Canton’s permissioned DLT, expanding beyond multi-signature custody to network-based collateral flows, integrated governance, and validator utility.

Amar Kuchinad, Global CEO of Copper, said: “As institutions adopt digital assets at scale, the need for secure, permissioned and compliant infrastructure is critical. Copper’s custody and collateral management technology is designed to meet that need, helping to advance Canton’s next phase of growth. We’re proud to back the Tharimmune Digital Asset Treasury in its acquisition of Canton Coin and to support the ongoing growth of the Canton Network.”

Mark Wendland, CEO of Tharimmune, Inc., noted: “We are taking a thoughtful approach as we launch the first publicly traded company with a Canton Coin digital asset treasury strategy. Working with an institutional-grade custodian like Copper gives us the ability to focus on our core mission: advancing the next generation of financial infrastructure by bringing the differentiated value of the Canton Network to public market investors.”
