Swiss digital assets bank Sygnum Bank has launched a regulated custody, trading and lending services for the Sui token, expanding institutional access following its appointment as the banking partner of the Sui Foundation.
Sui is a layer-one blockchain designed for mass adoption developed by Mysten Labs, a team of former Meta engineers. The Sui Foundation supports the development and adoption of the Sui blockchain, a layer-one network designed for speed, scalability and mainstream use.
“By offering regulated access to the Sui ecosystem, we are broadening the market reach of a blockchain built for mass adoption,” the bank said in a statement. The initiative gives Sui a regulated entry point for traditional investors looking to move into digital assets.
Sygnum was the “first” Swiss bank to fully integrate Sui into its regulated platform”, the bank stated, completing the rollout in July 2025. Its offering includes institutional-grade custody, spot and derivatives trading and staking services. Sui staking is due to launch in August, opening up yield-generating opportunities for token holders. Sui-backed Lombard loans will follow, providing clients with access to flexible liquidity solutions.
The integration enables professional and institutional investors—including banks, asset managers and high-net-worth individuals—to hold and transact Sui within a Swiss banking framework. Client assets are held off-balance sheet and are bankruptcy remote, aligning with regulatory standards and investor protection requirements.
Sui is also among the early adopters of BTCfi, a segment of Bitcoin-linked DeFi that enables bitcoin holders to participate in lending, trading and earning activities without compromising asset security.
“Broadening institutional access to the Sui ecosystem further expands Sui’s reach to the global institutional investor community,” said Christian Thompson, managing director, Sui Foundation. “Sygnum’s crypto-native team, end-to-end regulated offering and trusted infrastructure make them our ideal banking partner as we continue to build and scale.”
“We’re pleased to be a banking partner for the Sui Foundation and expand access to professional and institutional investors via Sygnum, a regulated bank”, said Mathias Imbach, Sygnum’s co-founder and group CEO. “Sygnum’s unique understanding of digital assets sits at the intersection of the rapidly converging digital asset and regulated financial ecosystems. We are excited to support the Sui Foundation in developing the future-proof, opportunity-ready treasury it needs to continue its growth trajectory.”
