Swiss digital asset bank Sygnum has partnered with the Sui Foundation to offer institutional-grade custody and trading for the SUI token, adding staking and collateral-backed loans later this year.
The Zurich- and Singapore-based bank said on Friday it will now provide professional clients with regulated custody, spot and derivatives trading for SUI. Staking services are expected to go live in the coming weeks, while SUI-backed Lombard loans are targeted for the fourth quarter. All holdings will remain off the bank’s balance sheet and set up to be bankruptcy remote.
The move follows Sygnum’s July integration of SUI into its platform — which it says made it the first Swiss bank to fully support the token — and is designed to capture growing demand from banks, asset managers and high-net-worth clients seeking compliant blockchain exposure.
Christian Thompson, managing director at the Sui Foundation, said the tie-up “connects Sui to global institutional investors through a trusted, regulated gateway.” Sygnum CEO Mathias Imbach called the bank’s role “an intersection of digital assets and traditional finance,” enabling clients to explore new opportunities within a secure regulatory framework.
Sui, developed by former Meta engineers at Mysten Labs, uses parallel transaction processing to boost scalability and supports decentralized finance, payments, asset tokenization and gaming. It has also positioned itself in the emerging BTCfi segment, allowing bitcoin holders to participate in DeFi without compromising security.
Sygnum holds banking and digital asset licenses in Switzerland, Singapore, Abu Dhabi, Luxembourg and Liechtenstein, offering regulated banking, asset management, tokenization and B2B solutions.
Sygnum recently secured $58 million in an oversubscribed strategic growth round, reaching a post-money valuation of over $1 billion. This figure elevates the company to unicorn status.
This funding follows Sygnum’s $40 million interim round in January 2024, which brought its valuation to $900 million, and a $90 million Series B round in 2022 that attracted major Asia-based investors like Animoca Brands and SBI Holdings.
Licensed in Luxembourg, Singapore, and Switzerland, Sygnum plans to acquire new licenses in Europe under the Markets in Crypto Assets (MiCA) regulations. Additionally, Sygnum intends to expand its regulated operations in Hong Kong.
