Startale Cloud Services x Rhinestone: A New Era of Modular Account Abstraction on Soneium
As the Soneium ecosystem gains traction with consumers, seamless user experience powered by Account Abstraction becomes a necessity, not a luxury.
Startale Cloud Services (SCS) and Rhinestone are proud to announce a technical collaboration that elevates both developer and end-user experience on Soneium through enhanced possibilities in what smart accounts can do. This marks the beginning of a strategic partnership to accelerate the adoption of Smart Accounts across Soneium applications. The partnership enables support for Rhinestone’s Modular Smart Account technology in Startale Account Abstraction SDK, the most popular AA infrastructure stack on Soneium.
As Sota Watanabe, CEO of Startale Group, notes: “To bring Web3 to billions, we must eliminate its complexity. Our partnership with Rhinestone lets us offer an even more powerful modular Account Abstraction that’s ready for real-world applications.”
This sentiment is echoed by Kurt, Co-Founder of Rhinestone: “Wallets are a crucial element of any onchain ecosystem. Modular smart accounts allows platforms like Soneium to offer web2-like UX whilst still enabling composability and creativity for developers. This was the core motivation behind ERC-7579 and we’re excited to support Soneium in utilising this powerful tool.”
About Rhinestone
Rhinestone empowers developers to build powerful, self-custodial Web3 applications by simplifying the complexities of smart accounts. They maintain the Modular SDK which enables developers to extend the functionality of smart accounts through plug-and-play modules while preserving interoperability across different account implementations. Rhinestone maintains a curated set of Core Modules—such as passkeys, session keys, and recovery—that offer essential, production-grade building blocks for developers to create flexible UX with minimal overhead.
As one of the principal authors of ERC-7579, Rhinestone has played a foundational role in shaping the modular smart account movement. Their deep contributions to Ethereum’s evolving standards ecosystem have laid the groundwork for cross-compatibility and composability, ensuring that developers can build scalable and interoperable smart accounts across platforms.
Rhinestone’s infrastructure continues to serve as a critical pillar for modular account abstraction, helping Web3 developers craft seamless experiences with the same flexibility and security expected from the best in Web2.
Why This Collaboration Matters
Web3 needs UX that feels effortless and familiar. Developers need infrastructure that’s modular, scalable, and smooth. This is where our visions align with Rhinestone.
With Rhinestone’s modular smart account architecture supported in Startale Account Abstraction, developers building on Soneium can now:
- Deploy modular smart accounts based on ERC-7579, a standard co-authored by Rhinestone to ensure interoperability across smart account and wallet ecosystems. These accounts can dynamically attach or detach functionalities like session keys, spending limits, and social recovery, enabling composability, flexibility, and seamless integration across different applications by default.
- Leverage Smart Sessions, a powerful way to delegate permissions to third-party agents or bots. This makes it possible to automate tasks or build agent-driven flows without compromising the security or sovereignty of a user wallet.
- Use Rhinestone’s plug-and-play modules to enhance UX while maintaining modularity: support for gas sponsorship, daily spend limits, and account recovery is just a few clicks away.
- Smart accounts cross chain interoperability powered by intent-based transaction system. laying the foundation for instant cross-chain executions while spending funds from any chain.
This support represents a leap forward—not just in technology, but in how we approach developer experience. It makes Account Abstraction on Soneium modular and customizable.
Available Now
The supported infrastructure is now available on Soneium. The future of smart accounts is modular. Let’s build it—on Soneium, for real users, and at scale.
