Cosmos’ Sovereign EVM Day at the upcoming Ethereum Community Conference (EthCC) in Cannes is shaping up to be one of the most critical side-events for blockchain builders and Layer 1 purists. The event will be a gathering point for teams that are not just theorizing about Ethereum interoperability, but actively building it, and Ripple, alongside Peersyst, is stepping up to show a real, working example.
Ripple has long been a major player in the blockchain space, but their latest move is a bold push toward programmability. In collaboration with Peersyst Technology, they will present the XRPL EVM sidechain, a powerful new environment built using the Cosmos SDK and secured with IBC (Inter-Blockchain Communication protocol). The sidechain brings smart contract functionality to the XRP Ledger, opening XRP up to an entirely new ecosystem of EVM-compatible applications.
But this isn’t just another pitch deck or future roadmap reveal. At Sovereign EVM Day, the XRPL EVM sidechain will be demonstrated live, standing shoulder-to-shoulder with cutting-edge projects like Babylon, TAC, Stride, and Starknet. This is a real deployment, with real chains and use cases, and it’s built to scale with Cosmos at the core.
What Is the XRPL EVM Sidechain?
The XRPL EVM sidechain is Ripple’s latest development to extend the functionality of the XRP Ledger. Traditionally limited by its original design as a fast, payments-focused network, XRP hasn’t natively supported Ethereum-style smart contracts. That’s changing now.
By using the Cosmos SDK and integrating with IBC, Ripple and Peersyst have created a sidechain that connects seamlessly with existing EVM ecosystems while still benefiting from XRP’s speed and liquidity. This means developers can now build dApps, DeFi protocols, NFTs, and more, all while settling in XRP.
It’s not just theoretical. The team is bringing this work live to the stage at EthCC’s Sovereign EVM Day to show the XRPL EVM sidechain in action, bridging the gap between Cosmos and Ethereum, and between liquidity and programmability.
Why Build It on the Cosmos Stack?
Many may question, why Cosmos? The simple answer is interoperability, and specifically, Cosmos interoperability. The Cosmos SDK is very modular and open-source, and has been extensively tested on numerous successful chains. It allows projects, such as the XRPL EVM sidechain, to build sovereign and application-specific blockchains, while still maintaining interoperability across the Cosmos ecosystem through IBC.
By building on the Cosmos Stack, the XRPL EVM sidechain achieves the benefits of fast finality, flexibility for customization, and seamless multichain communication. It essentially achieves a triple-win: decentralization of Ethereum, liquidity of XRP, and interoperability backbone of Cosmos.
With Cosmos interoperability being part of its foundation, this sidechain is not designed to be a stand-alone chain. Instead, it is designed to complement the web of inter-chain blockchains, allowing trustless asset transfer and sharing of composability across ecosystems.
Who’s Behind This Development?
At the forefront of this transformation is Peersyst Technology, Ripple’s key partner on the technical side. Peersyst brings deep experience in blockchain development and has worked with Ripple on multiple projects, including early versions of sidechain architecture.
At Sovereign EVM Day, Ferran Prat, representing Peersyst, will take the stage to walk attendees through the technology, benefits, and roadmap of the XRPL EVM sidechain. It’s not just about theory or ideas, it’s about execution and functionality.
By appearing alongside other prominent projects such as Stride, TAC, Babylon, and Starknet, Ripple and Peersyst signal their commitment to making the XRP ecosystem more relevant and developer-friendly in the cross-chain era.
What’s Next for the XRPL EVM Sidechain?
The XRPL EVM sidechain is now formally entering the next phase with its live demonstration at EthCC. It is no longer a concept – it is a live, scalable, interoperable chain. Programmers are going to engage with it, Ripple will keep integrating Coin- native tools, and they will be moving in more DeFi and enterprise use cases.
The sidechain will change and develop incredibly quickly, especially with the growing interest in Cosmos SDK projects and cross-chain liquidity. As more dApps start to migrate or expand into EVM-compatible environments, XRPL EVM sidechain has an unparalleled offering: the speed and finality of XRP – but now also programmable and interoperable.
Final Thoughts
The Sovereign EVM Day at EthCC 2025 isn’t just another conference panel, it’s a proving ground. And Ripple, in partnership with Peersyst, is ready to show what the XRPL EVM sidechain can do. With the support of the Cosmos SDK and powered by Cosmos interoperability, this new ecosystem could redefine how XRP is used in the world of programmable finance.
Whether you’re a developer, investor, or just someone following blockchain innovation, the XRPL EVM sidechain’s debut marks a pivotal moment in bridging old networks with new tech. And thanks to Cosmos, that bridge is already built, and traffic is coming.
