Sygnum Partners with Sui Foundation to Expand Institutional SUI Access

Sygnum Bank has partnered with the Sui Foundation to offer institutional-grade custody and trading services for the SUI token, marking a significant step toward regulated institutional adoption of blockchain-based assets. The Zurich- and Singapore-based digital asset bank announced that it now provides custody, spot, and derivatives trading for SUI to professional clients. Staking services are set to launch in the coming weeks, followed by SUI-backed Lombard loans in the fourth quarter. All SUI assets held by Sygnum will remain off the bank’s balance sheet and are structured to be bankruptcy-remote, reinforcing the security and regulatory compliance of the offering [1].

This initiative builds on Sygnum’s July 2025 integration of SUI, which the bank claims made it the first Swiss institution to fully support the token. The partnership aims to meet the increasing demand from asset managers, banks, and high-net-worth individuals for compliant blockchain exposure. Christian Thompson, managing director at the Sui Foundation, described the collaboration as a critical step in connecting the Sui blockchain to global institutional investors via a “trusted, regulated gateway.” Sygnum CEO Mathias Imbach emphasized the bank’s role as an intersection of digital assets and traditional finance, enabling clients to access new opportunities within a secure regulatory framework [1].

The Sui blockchain, developed by ex-Meta engineers at Mysten Labs, employs parallel transaction processing to enhance scalability. It supports decentralized finance (DeFi), asset tokenization, payments, and gaming. The platform has also positioned itself in the emerging BTCfi segment, offering Bitcoin holders a way to engage with DeFi without exposing their assets to additional risks. Sygnum’s integration of SUI expands the ecosystem’s access to institutional-grade financial tools, including staking and collateralized lending [1].

Sygnum is licensed in multiple jurisdictions, including Switzerland, Singapore, Luxembourg, and Abu Dhabi, and plans to secure additional licenses under Europe’s Markets in Crypto Assets (MiCA) regulations. The bank recently completed a $58 million strategic growth round, bringing its valuation to over $1 billion, following a $40 million interim funding round in January 2024 and a $90 million Series B round in 2022. These investments reflect confidence in Sygnum’s role as a bridge between traditional finance and digital assets [1].

The partnership with Sygnum also aligns with broader institutional interest in SUI. Earlier in 2025, another Swiss bank, AMINA Bank AG, launched custody and trading services for SUI under FINMA regulation. SUI is also under consideration for inclusion in several ETF applications, including those from Canary Capital and 21Shares, and is already part of Bitwise’s crypto index ETF. These developments, paired with regulated banking support, are expected to drive further recognition and adoption of the token [1].

Sygnum’s expansion of services for SUI includes its Sygnum Connect platform, which enables instant fund settlement across digital assets, fiat, and stablecoins. The platform offers features such as delivery-versus-payment transactions, on-demand Lombard loans, and foreign exchange conversions. These tools support Sygnum’s mission to facilitate seamless and secure transactions between traditional and digital finance [1].

The Sui Foundation has highlighted Sygnum’s crypto-native expertise and robust infrastructure as key factors in the partnership. By leveraging Sygnum’s regulated banking platform, the Sui ecosystem gains broader institutional exposure and credibility. The collaboration underscores a growing convergence between blockchain innovation and traditional financial systems, with Sygnum positioning itself as a leader in regulated digital asset infrastructure [1].

As the digital asset market continues to evolve, partnerships like this one are likely to shape the future of institutional-grade crypto services. The expansion of regulated access to SUI, combined with the token’s growing presence in ETF applications and institutional portfolios, signals a maturing market where compliance and innovation can coexist [1].
