XRPL EVM Sidechain Prepares for v11 Upgrade: Security and Cross-Chain Improvements on the Way

Blockchain development firm Peersyst has officially announced an upcoming upgrade to the XRP Ledger EVM sidechain, signaling a new phase of technical maturity for the network. The release, dubbed XRPL EVM v11, is designed with a clear priority in mind: making the network safer, more robust, and easier to manage over the long term.

The XRPL EVM sidechain serves as a bridge between the XRP Ledger ecosystem and Ethereum-compatible smart contract functionality. Since its Mainnet launch in June 2025, the network has undergone a series of incremental improvements. Ripple's RLUSD stablecoin joined the sidechain in June of that year as part of a broader multichain expansion strategy.

According to a post shared by Peersyst on X, the v11 upgrade will target four core areas: improved economic security, safer cross-chain connectivity, enhanced validator management, and additional hardening across the technology stack. Peersyst indicated that a Testnet proposal would be submitted as early as the current week, with a Mainnet rollout to follow shortly after.

Unlike many blockchain updates that introduce flashy new features, v11 takes a more foundational approach. The majority of its changes operate behind the scenes, meaning developers and end users may notice little difference in day-to-day interactions. Nevertheless, these modifications are expected to significantly improve the network's long-term resilience and security posture.

One of the most notable structural changes in v11 involves the validator system. The XRPL EVM operates on a Proof-of-Authority consensus model, where a designated authority controls changes to the validator set rather than relying on open staking. The upcoming release introduces two key modifications to this system. First, the standard path for creating new validators will be blocked after launch, ensuring that no new participants can join the validator set outside of the established authority process. Second, validators will now have the ability to voluntarily exit the network without requiring the authority to intervene and remove them manually.

Another significant aspect of v11 is its integration of AI-assisted security auditing. The XRPL EVM has been running a recurring, AI-supported audit process, and v11 marks the first release to have benefited from this review end to end. This signals a growing trend within blockchain infrastructure development toward leveraging artificial intelligence for proactive vulnerability detection.

The upgrade also addresses the IBC, or Inter-Blockchain Communication, layer — a critical component for enabling safe and reliable cross-chain transactions. Hardening this layer reduces the potential attack surface and strengthens the overall integrity of cross-chain operations.

In summary, XRPL EVM v11 represents a security-first milestone for the sidechain, reflecting Peersyst's commitment to building a stable and trustworthy foundation for the ecosystem. As the network continues to expand its user base and integrate with broader DeFi infrastructure, updates like this one play a vital role in ensuring its long-term viability.
