Startale Account Abstraction powers up Soneium for unlocking web3 adoption

Startale today announces the launch of Startale Account Abstraction (AA) on the Soneium Mainnet, bringing production-grade modular smart accounts, paymasters, and gasless UX to developers building real-world web3 apps. Account Abstraction marks a significant evolution in the Soneium ecosystem—equipping developers with the tools to build entertainment and financial applications that feel as seamless as modern consumer platforms. With this release, Startale becomes one of the first AA providers for Soneium, delivering a complete infrastructure stack that includes ERC-7579-based smart accounts, advanced paymaster models, high-throughput bundling, and a unified user wallet. The first production integration, Yoake—a fan engagement platform built for fans and artists—has completed AA integration and is actively testing the seamless experience, giving developers a concrete preview of how real-world entertainment use cases can be built and refined using smart accounts.

"Implementing Account Abstraction (AA) has been a game-changer for how we approach onboarding and smart contract design. Features like gas sponsorship are allowing us to envision and build functionalities we previously thought were impossible. We’re incredibly optimistic about what this collaboration with Startale AA means for the future."

- Sota Moriyama, CBO of YOAKE entertainment

For developers building games, loyalty apps, digital banks, or creator tools, Startale’s infrastructure unlocks new levels of usability and developer flexibility onchain that are increasingly achievable across the ecosystem. Startale brings those capabilities to the Soneium ecosystem through a tightly integrated, developer-first stack purpose-built for entertainment and financial use cases: a UX without gas, key management, or onboarding friction.

The Developer Stack You’ve Been Waiting For

Startale AA is designed with one goal in mind: to make developers' lives easier. From initial setup to scaling in production, the entire stack is built to be flexible, modular, and fast to integrate. At its core is native support for ERC-7579, a modern smart account standard that allows developers to customize account behavior using plug-and-play modules like social login—enabled through collaboration with Privy and soon Dynamic, social recovery, session keys, spending limits, or two-factor authentication—without having to build complex backend systems.

The plugin-based approach makes it easy to test and deploy new features quickly, reuse well-tested components across projects, and integrate third-party tools without changing the foundation of your app. Since ERC-7579 was designed from the ground up to be modular, developers can add or update logic—like social recovery, spending limits, or authentication layers—without modifying the base account. Unlike ERC-4337, which often requires bundling features into monolithic contracts or relying on non-standard workarounds, ERC-7579 enables a cleaner, more flexible architecture that scales across teams and use cases. This architecture supports faster iteration, reduces security risks, and enables a clean separation of concerns, letting teams experiment, scale, and tailor experiences with minimal effort. For developers, this means faster builds, more reliable upgrades, and the freedom to ship novel features without compromising stability.

Each account can be paired with one of multiple paymaster configurations. Want to subsidize gas for new users? Use managed paymasters with credit-card-backed billing. Need to let users pay fees in USDC or platform tokens? Token paymasters route ERC-20s to cover costs seamlessly. Or use a self-funded setup, where developers deposit native tokens to cover gas for their users without relying on credit cards or off-chain systems. You choose. You configure. You build the flow your app needs.

Transactions are bundled behind the scenes. Gas is abstracted. Users log in with familiar credentials like email or social accounts. The wallet interface consolidates all interactions across dApps. And developers get access to monitoring dashboards, quota alerts, and end-to-end SDKs to move from concept to production in days. YOAKE will soon launch its flagship dApp with Startale AA integration.

On YOAKE, all blockchain experience would be abstracted for fandom to engage with their favorite.

Along with YOAKE, leading projects on Soneium like Arcas Games, Kyo Finance and Supervol has also committed to building using Startale AA.

“We’re excited to see the results of working with Startale AA. It has allowed us to significantly improve the user journey in our game, turning the typical clunky web3 experience into a seamless, intuitive flow which feels familiar to even non crypto users!”

By Dandadev, Founder of Arcas Games

“Account Abstraction is a great way to reduce user friction. Enabling users to pay in ERC-20 tokens or sponsor gas dynamically based on usage records opens up new ways to reward and retain our customers. With the Startale AA stack, we were able to abstract away the technical complexity of implementing AA. It also gave us the foundation to power AI agents that act on behalf of users to automate key actions. This is the first stack that made that level of automation feel production ready.”

By Kai, Co-Founder of Kyo Finance

“Account Abstraction is key to our goal: bridging Web2 and Web3 through gamified trading. With gasless trades and social login, SuperVol now feels as seamless as any Web2 app. Playing is more fun when the friction disappears—and Startale AA makes that possible.”

By Jun, BD at SuperVol

With early adopters proving what’s possible, Startale AA is setting a new bar for usability and scalability across the Soneium ecosystem.

Built for Soneium. Built for Scale.

What sets Startale apart isn’t just its technical architecture - it’s the way its infrastructure is deeply integrated into the infrastructure of the Soneium ecosystem. Rather than operating as a generic plug-in, Startale AA is designed to work seamlessly within the Soneium ecosystem, with production-ready tooling to simplify developer adoption. This deep integration enables session continuity across Apps, unified smart account views. It provides developers with a coherent experience layer that simplifies building intuitive, cross-functional user journeys across the ecosystem. This is also what powers Global Wallet - Startale’s upcoming identity and asset management layer that brings all of a user’s Web3 presence into one secure and familiar interface.

Soneium, an Ethereum layer-2 developed by Sony Block Solutions Labs, is a versatile general-purpose blockchain platform that aims to evoke emotion, empower creativity, and realize the open internet that transcends boundaries. Startale AA is what makes these apps usable.

Where legacy chains and AA platforms force developers to fight infrastructure, Startale turns that infrastructure into a launchpad. Gasless micropayments. Smart accounts with conditional access. Walletless sign-ins for onboarding millions. If you’ve wanted to build a blockchain-powered game, media platform, fan economy, or fintech experience-you finally can.

A Word from the CEO

“Account abstraction isn’t just about making web3 usable—it’s about making it invisible,” said Sota Watanabe, CEO of Startale Group. “We’re building the foundation for a future where developers create apps that feel native and familiar, while users enjoy seamless　experiences without ever thinking about the blockchain beneath.”
