The global entertainment titan Sony Group has officially entered the Web3 arena with the launch of Soneium, a new Ethereum Layer 2 blockchain developed in collaboration with Astar Network. This strategic alliance marks a pivotal moment in the evolution of decentralized technology, combining Sony’s vast intellectual property (IP) and user base with Astar’s proven blockchain expertise. Together, they aim to bridge the gap between mainstream audiences and Web3, transforming how fans interact with digital content.
The Rise of Soneium: Sony’s Bold Move into Web3
In January 2025, Sony Blockchain Solutions Labs (Sony BSL), a joint venture between Sony Group and blockchain innovator Startale, launched Soneium—an OP Stack-based Layer 2 network built on Ethereum. Unlike typical corporate blockchain experiments, Soneium is positioned as a core component of Sony’s long-term digital transformation strategy.
“Soneium isn’t just a tech experiment—it’s a gateway to redefining digital ownership, fan engagement, and cross-platform experiences,” said a senior executive at Sony BSL.
With over 170 projects joining the ecosystem within just two weeks of launch, including consumer-focused platforms like Yay! and Yoake, Soneium is demonstrating rapid adoption and real-world utility. The network leverages Ethereum’s security while offering faster transactions and lower fees, making it ideal for mass-market applications.

Why Soneium Matters: Strategic Vision Behind the Launch
Sony’s 2025–2027 corporate strategy emphasizes “breaking boundaries” and maximizing synergy across its divisions—entertainment, gaming, finance, and technology. Soneium serves as the connective tissue for this vision.
Short-Term Integration: Building on Existing Web3 Foundations
Sony already has foundational Web3 assets:
- SNFT: An NFT marketplace launched in 2022.
- WhaleFin (formerly S.BLOX): A crypto exchange acquired in 2023.
These platforms are now being integrated into the Soneium ecosystem. For example:
- Sony Pictures Entertainment (Japan) is offering exclusive film content via NFTs on Amazon Prime Video.
- Sony Music France released limited-edition NFTs celebrating the Sunny B. 1991 anniversary.
- Sony Music Japan launched NFT experiences tied to live performances by girl group “SANDAL TELEPHONE.”
These initiatives focus on enhancing fan engagement through digital collectibles and exclusive access—laying the groundwork for deeper Web3 integration.
Long-Term Potential: Convergence of Entertainment and Finance
Web3 opens new revenue streams across Sony’s core businesses:
- PlayStation: Could integrate NFT-based in-game assets or allow purchases using stablecoins.
- Music & Film: Monetize IP through tokenized royalties, fan tokens, and decentralized licensing.
- Financial Services: Sony Bank has already piloted STOs (Security Token Offerings) and stablecoin projects.
By unifying these verticals under a single blockchain layer, Soneium enables seamless interactions—like using a PlayStation wallet to buy concert NFTs backed by Sony Music IP, paid for with a Sony-issued stablecoin.
Key Use Cases in the Soneium Ecosystem
Yay!: Bridging Web2 and Web3 with SocialFi
Yay! is a Japanese social platform with over 10 million users and 100,000 active communities. It exemplifies how Web3 can enhance traditional apps without disrupting user experience.
Users earn $EMPL tokens for participating in communities, which can be spent in-app or converted to $YAY for cash withdrawal. Behind the scenes, all blockchain operations are abstracted—users don’t need wallets or seed phrases.
Crucially, Yay! supports both casual users and crypto natives:
- Casual users enjoy gamified rewards.
- Advanced users can stake $YAY or provide liquidity in DeFi protocols.
This dual approach has attracted over 20 million participants to its staking programs—proving that mass adoption is possible when friction is removed.

Yoake: Reinventing Fan Culture with Blockchain
Co-developed by legendary producer Akimoto Yasushi (creator of AKB48) and Startale, Yoake tackles two major pain points in fan ecosystems: vote manipulation and opaque royalty distribution.
On Soneium, every vote is recorded immutably on-chain. Fans can participate using their social media accounts—no wallet required. The system powers everything from song selection to fashion contests, ensuring fairness and transparency.
Yoake will launch its own $YOAKE token to reward active fans and measure community influence. This model could become a blueprint for future entertainment platforms seeking deeper fan involvement.
Why OP Stack? Infrastructure for Scalability
Instead of building a custom Layer 1, Soneium chose Optimism’s OP Stack, enabling it to inherit Ethereum’s security while achieving high throughput and low costs.
Key advantages:
- EVM compatibility: Works seamlessly with existing wallets and tools.
- Superchain integration: Can interoperate with other OP Stack chains like Base and World Chain.
- Future-proof design: Will leverage Optimism’s Interop protocol for direct cross-chain communication.
This pragmatic choice allows Soneium to focus on user experience rather than infrastructure battles—a critical factor for mainstream success.
The Astar Network Partnership: Synergy Beyond Chains
While Soneium runs on Ethereum, Astar Network—a Polkadot-based smart contract platform—plays a crucial role as its strategic partner. Despite different underlying architectures, their collaboration creates powerful synergies.
Cross-Ecosystem Expansion
Astar supports both EVM and WebAssembly (WASM), acting as a bridge between Ethereum and Polkadot ecosystems. Its experience managing large-scale dApp staking and liquidity programs helps accelerate Soneium’s growth.
Notably:
- Astar launched Chain Abstraction Layer (CAL) using Chainlink CCIP and LayerZero for seamless cross-chain messaging.
- It introduced dApp Staking V3, improving capital efficiency and rewarding developers.
These innovations are now being adapted for Soneium, creating a shared ecosystem where assets and data flow freely.
ASTR: The Core Asset of Soneium’s Economy
Rather than launching a new token, Soneium uses ASTR—Astar’s native token—as its foundational asset.
Why ASTR?
- Listed on major exchanges (Binance, OKX, Upbit), ensuring immediate liquidity.
- Already holds 57% of Soneium’s Total Value Secured (TVS) as of February 2025.
- Compliant with ERC-7802 (SuperchainERC20), enabling smooth transfers across Optimism’s Superchain.
Through initiatives like Astar Surge, $1.68 million in liquidity was directed to key Soneium projects like Yay! and Sake Finance. The upcoming Astar Contribution Score (ACS) will further incentivize user activity across DeFi, gaming, and consumer apps.
Solving Rollup Delays with AltLayer
As an optimistic rollup, Soneium faces transaction finality delays:
- ~13 minutes for hard confirmation.
- 7-day withdrawal window from L1.
To address this, Soneium integrates AltLayer’s MACH protocol, an Active Validation Service (AVS) powered by EigenLayer’s restaking mechanism. This reduces withdrawal times significantly—critical for gaming and finance dApps.
Importantly, ASTR will be used alongside staked ETH in MACH validation, giving token holders new ways to earn yield and participate in network security.
Balancing Innovation and IP Protection
One of Web3’s biggest challenges is unauthorized use of intellectual property (e.g., NEIRO disputes, CHILLGUY controversies). Soneium addresses this with a “sandbox” governance model:
- Projects undergo a warning period during which suspicious contracts are flagged.
- Instead of outright bans, restricted access acts as a “speed bump”—allowing fixes before full reinstatement.
- Full Ethereum L1 access remains open for advanced users.
This approach aligns with Vitalik Buterin’s vision of “responsible decentralization,” protecting creators while preserving innovation.
