Sygnum Bank Doubles Down on SUI: Swiss Giant Brings Regulatory Firepower to Sui Blockchain

Move over, legacy finance—Sygnum just handed Sui a golden ticket.

The Swiss crypto-native bank, already a heavyweight in digital asset custody, is rolling out institutional-grade support for SUI. No more gray-market OTC desks or sketchy offshore ramps.

Regulated On-Ramps Go Live

Sygnum’s FSA-approved infrastructure now lets clients trade, store, and stake SUI with the same compliance checks as traditional securities. Finally, a blockchain project that doesn’t make compliance officers break out in hives.

Why This Matters

Sui’s tech stack—built for DeFi at scale—just got its first blue-chip banking partner. Meanwhile, rival L1s are still begging for Binance listings. The message? Institutional adoption isn’t coming. It’s already here.

Switzerland’s Zuger Kantonalbank, a leading Swiss cantonal bank, has expanded its cryptocurrency offerings to include Cardano (ADA) and Avalanche (AVAX).

“The addition of Cardano and Avalanche to our growing cryptocurrency offering enables our clients to further develop their crypto portfolios conveniently with their principal bank – at a time when digital assets are approaching a global inflection point in terms of adoption,” said Jan Damrau, Member of the Zuger Kantonalbank Executive Board.

Importantly, to expand its crypto offering, Zuger Kantonalbank partnered with Sygnum, the popular global digital asset banking group.
