Sepior’s Threshold Signature MPC Technology Underpins Digital Asset Security for SBI DAH’s sbiwallet Institutional Grade Custody Services

Tokyo, Japan, April 26, 2021 (GLOBE NEWSWIRE) -- Sepior ApS and SBI Digital Asset Holdings (SBI DAH), the digital asset arm of the SBI Group, today announced the integration of Sepior™ ThresholdSig software with the sbiwallet to provide digital asset custody solutions and banking services worldwide, enabling a flexible, scalable, and trustworthy digital asset ecosystem.

The partnership began nearly three years ago, when SBI Group first selected Sepior to jointly develop the industry’s first Multiparty Computation (MPC) based wallet in 2018. Since then, SBI has greatly expanded their investments, acquisitions and joint developments in the digital asset space, leading to the formulation of a comprehensive digital asset strategy under SBI Digital Asset Holdings Co., Ltd in 2020.

“Sepior has proven to be a truly reliable and innovative partner,” said Fernando Luis Vazquez Cao, chief executive officer of SBI Digital Asset Holdings. “The digital asset market is evolving rapidly and we’ve expanded our focus to assist other financial institutions with their entry into this space. As we reviewed our customer’s solution requirements, Sepior proved once again to offer the most compelling cryptographic technology for us to integrate as part of our wallet and broader digital asset ecosystem.”

“SBI has been a fantastic customer and partner,” said Ahmet Tuncay, chief executive officer of Sepior. “Their breadth of ecosystem knowledge, cutting-edge mindset, and rigorous commitment to security and scalability has pushed us to develop what we believe is the most secure, flexible, scalable, and resilient digital asset technology available.”
