Sepior Advanced MPC™

Secure Multiparty Computation (MPC) has emerged as the security technology of choice for major digital asset investors and service providers. However, not all MPC technologies and implementations are created equally.

Sepior has partnered with digital asset service providers to create a purpose-built, performance optimized implementations of MPC, known as Advanced MPC™ since 2018. We’ve developed patented techniques to conduct pre-computations, which eliminate the traditional MPC dependency on multiple iterative computation cycles to generate a signature. The result is industry-leading throughput, supporting in excess of 10,000 transactions per second, and many other operational benefits.

Sepior has also embraced the reality that a single implementation of MPC will not be optimal for all applications. As a result, Sepior offer a variety of multiparty threshold schemes including 2 of 2, 2 of 3, 3 of 3, and other m of n models.

Sepior Advanced MPC™ represents years of innovations and optimizations, yielding higher security, flexibility and performance than any known alternatives.

Sepior Advanced MPC™ provides the assurance your customer’s want. Go forth confidently, knowing that your MPC-based wallet and/or custody solutions are backed by Sepior’s world renowned cryptographers, and proven MPC technology.

World-Renowned Cryptographers With a Track Record in MPC

Sepior has been developing application optimized implementations of MPC since 2014. Prior to founding Sepior, our co-founders were part of the cryptography team that developed and implemented the world’s first production deployment of MPC in 2008, and they continue to provide industry-leading MPC-based solutions today.

While MPC has emerged as the crypto key security technology of choice, not all of the companies offering MPC-based solutions have the same level of expertise and experience in developing MPC to provide optimal levels of Security, Scalability, and Flexibility.

Sepior’s Advanced MPC™ underpins the crypto security for many of the most respected names in conventional financial markets and crypto asset markets. By working with market leaders for years, we’ve developed what is believed to be the most secure, flexible, and highest-performing MPC-based crypto wallet and custody security technologies available on the market today.

Third Party Tested and Validated

Sepior’s Advanced MPC™ protocols undergo periodic security reviews by independent and highly respected firms specializing in cryptography such as the NCC Group and CryptoExperts. Live tests of Sepior's source code are used to validate that our implementations match the published protocol specifications and security proofs. Overall security posture of the implementations are also assessed including authentication, exposure to application security vulnerabilities, denial of service attacks, and channel encryption. This independent third-party assessment ensures that the services and software delivered by Sepior provide the best possible protection for our customers.
