As XRP Ledger expands from a payment network to native lending and institutional DeFi, protocol security is being given greater prominence. RippleX, Ripple's development arm, stated that the more complex an on-chain financial instrument, the more difficult it is to cover all risks in a single audit, and security processes need to be integrated throughout the development, testing, and pre-launch phases.
Two upgrades enter key review
This new process is initially used for two key upgrades to XRPL: Lending Protocol (XLS-66) and Single Asset Vault (XLS-65). These two features will bring lending capabilities directly to the ledger layer, which also means the protocol will face a larger attack surface.
RippleX Engineering Lead Ayo Akinyele stated that security cannot rely on a single final check, but should be mitigated through continuous testing, independent verification, and multi-layered protection. RippleX hopes to reduce issues arising from consensus failures, economic attacks, and unintended interactions between new features in this way.
AI review and public defense are proceeding simultaneously.
With AI tools accelerating vulnerability discovery, RippleX has also moved its security review process forward to the development stage. The article indicates that the two XRPL upgrades mentioned above have undergone a more comprehensive security process, including formal verification, multiple independent audits, AI-assisted analysis, verifier review, fuzz testing, community testing, bug bounties, and attack/defense drills.

- The prize pool is 200,000 RLUSD.
- Open the XRPL codebase to researchers worldwide
According to the data in the article, more than 130 researchers reviewed nearly 35,500 lines of C and C++ code and submitted hundreds of reports. After screening, the team identified dozens of valid vulnerabilities, including some critical issues that were fixed before further deployment.
Community testing covers more adversarial scenarios
In addition to the routine review, RippleX also mentioned that the AI-driven red team testing uncovered some risks that traditional processes might miss, including flawed system assumptions, potential spam attacks, and node stability issues.
XRPL Commons also participated in community-side testing, completing hundreds of test cases across different transaction types and adversarial scenarios, and achieving full verification. Meanwhile, validator testing and large-scale fuzz testing were also incorporated into the overall process to supplement security checks at different levels.
RippleX states that this approach is not limited to XLS-65 and XLS-66. Its goal is to make overlapping security reviews a standard procedure for subsequent XRPL upgrades, rather than conducting isolated checks only when a feature is close to launch.
For XRPL, this means its positioning is shifting further from a payment-oriented blockchain to a platform capable of supporting more complex financial infrastructure. As native lending and institutional applications advance, a more rigorous testing system will also become part of the protocol development process.
