Application security assessment

Bitcoin.com

Bitcoin.com was preparing to launch a new web-based wallet built on multi-party computation. The goal was to deliver a seamless, non-custodial experience where private key shares are split between the user and their Google account without compromising security. With this novel approach, Bitcoin.com needed independent validation of the entire security architecture before going live.

Advix ran a deep technical assessment covering all critical areas:

  • Authentication and authorization flows
  • Cryptographic design and key management logic
  • MPC implementation and threat modeling
  • Full code review and dynamic testing in a sandbox environment

We worked closely with the Bitcoin.com team to identify and help fix several minor issues, ensuring the wallet’s infrastructure was robust and ready for production.

As a result, all issues were promptly resolved and revalidated. Bitcoin.com launched a safer, more resilient wallet, with the confidence that its security design had been thoroughly tested. The collaboration supported a smooth release and strengthened trust in a product used by millions.
