• Galaxy Digital partners with Mill City Ventures to manage a $450 million SUI treasury strategy. 

• SUI price jumped 2.7% following the announcements and gained 29.4% over the past month.

Swiss banking giant Sygnum Bank has announced comprehensive institutional services for SUI, marking a significant milestone for the blockchain ecosystem. The $1 billion regulated bank becomes the first Swiss institution to integrate SUI into its banking platform fully.

Galaxy Digital has simultaneously partnered with Mill City Ventures to manage a $450 million SUI treasury, creating the largest public market SUI holding currently available.

Sygnum Bank Launches Full SUI Integration

Sygnum Bank officially introduced custody and trading services for SUI tokens through its regulated platform. The bank serves as the official banking partner to the Sui Foundation, expanding professional and institutional access to the blockchain globally.

The comprehensive service package includes secure off-balance sheet SUI custody, spot trading, and derivatives trading capabilities. Sygnum plans to launch staking services and Lombard loans backed by SUI collateral soon.

Client assets remain bankruptcy-remote while benefiting from bank-grade security infrastructure. This structure provides institutional investors regulated exposure to SUI through traditional banking channels.

“Broadening institutional access to the Sui ecosystem further expands Sui’s reach to the global institutional investor community,” stated Christian Thompson, Managing Director of the Sui Foundation.

Mathias Imbach, Sygnum’s Co-Founder and CEO, emphasized the bank’s unique position bridging regulated finance and digital assets. The integration combines Swiss banking security standards with institutional-grade asset management capabilities.

Galaxy Digital Manages $450 Million SUI Treasury

Mill City Ventures announced a strategic partnership with Galaxy Digital to oversee a $450 million SUI treasury strategy. This represents the largest SUI treasury in public markets and receives direct foundation support.

Galaxy Asset Management will handle execution, liquidity solutions, and staking strategies to optimize long-term holdings. Galaxy Digital participated as a major investor in Mill City’s $450 million private placement, funding the treasury.

Mill City’s Chief Investment Officer Stephen Mackintosh described Sui as “the infrastructure layer for the next chapter of the internet.” He highlighted the long-term investment approach underlying their substantial SUI position.

“Having the support of Galaxy as both asset manager and investor is a major unlock. Their institutional-quality infrastructure will actively allow us to manage our SUI treasury for today and tomorrow,” Mackintosh explained.

Global Head of Asset Management at Galaxy Digital, Steve Kurz, positioned Mill City’s public-market structure as “a new access point for investors to engage with transformative blockchain ecosystems.”

SUI price increased 2.7% to $3.81 following the announcements. The rally extends a 9.5% weekly gain and contributes to a 29.4% monthly surge.

These institutional partnerships signal growing confidence in Sui’s blockchain infrastructure among traditional finance players. The combination of regulated banking services and professional treasury management provides multiple institutional entry points into the SUI ecosystem.
