By focusing on secure storage, user interactions, and communication with the XRP Ledger, Xumm backend, and xApps, the audit provided valuable insights into areas for improvement.
The team at Cossack Labs stated: “We would like to note a solid security-oriented engineering effort of the XRPL Labs team in building and securing the app.” pointing towards all of the security features XRPL Labs added to Xumm over the years, such as application locking, passphrases, data-at-rest encryption, user authentication, and many more.

Wietse Wind, the Founder, and CEO of XRPL Labs, said, "We've always been transparent about prioritizing security. The self-custody space deserves nothing less, and our goal is to lead the way in helping our users manage and use their private keys responsibly and securely. We are thrilled and proud to not only claim that we care about security but also showcase a security audit that led to actionable improvements, which we've integrated into recent Xumm updates."
