The convergence of entertainment, technology, and blockchain has long been seen as a potential catalyst for Web3 mass adoption. The Astar-Soneium alliance represents one of the most promising real-world examples of this vision in motion. Spearheaded by Sony Group’s entry into Web3 via the Soneium blockchain and powered by Astar Network's technical and ecosystem expertise, this partnership is redefining how mainstream audiences interact with decentralized technologies.
With Sony’s vast intellectual property (IP) library, global user base, and legacy of innovation, combined with Astar’s proven track record in blockchain operations, the collaboration is accelerating the path toward Web3 mainstream adoption, cross-chain interoperability, and real-world utility.
Sony Group Enters Web3: A Strategic Evolution
In January 2025, Sony Group officially launched Soneium, an Ethereum Layer 2 network developed through its subsidiary, Sony Blockchain Solutions Lab (Sony BSL). This move marks a pivotal shift in corporate blockchain strategy — moving beyond pilot projects to full-scale ecosystem development.
Unlike many enterprises that approach Web3 cautiously, Sony embraced the challenge head-on, addressing three major industry hurdles: regulatory uncertainty, unproven business models, and infrastructure costs. Instead of retreating, Sony leaned into its legacy of innovation — from Walkman to PlayStation — to establish a new digital frontier.
Central to this vision is the partnership with Startale, the team behind Astar Network, a leading Polkadot-based smart contract platform. Astar brings over five years of mainnet experience, developer tools, and community governance frameworks — all critical for rapid ecosystem scaling.

Soneium: Building the Bridge to Mainstream Web3
Soneium is built on OP Stack, the same modular framework used by Optimism, Base, and other leading Ethereum L2s. This strategic choice enables Soneium to inherit Ethereum’s security, EVM compatibility, and developer ecosystem while focusing on user-centric applications.
Short-Term Strategy: Integrating Existing Web3 Services
Sony’s immediate goal is to unify its existing Web3 ventures under the Soneium umbrella:
- S.BLOX: Formerly WhaleFin, this regulated crypto exchange is evolving into a secure gateway between traditional finance and Web3.
- SNFT: Sony’s NFT platform now integrates with Soneium, enabling IP-rich digital collectibles across music, film, and gaming.
Early implementations are already live:
- Sony Music Japan launched NFT campaigns tied to the girl group “SANDAL TELEPHONE.”
- Sony Pictures Japan offers exclusive content access via NFTs for Amazon Prime viewers.
- Sony Music France celebrated its “Sunny B. 1991” community with limited-edition NFTs.
These initiatives go beyond speculation — they enhance fan engagement and open new monetization channels.
Long-Term Vision: Converging Entertainment and Finance
Sony’s entertainment division generates 60% of its revenue, controlling content creation, distribution, and consumption. Soneium could become the connective tissue across these domains.
Potential future integrations include:
- PlayStation: Blockchain-powered in-game assets (NFTs) and crypto payments.
- Sony Music & Film: Tokenized IP rights, royalty distribution via smart contracts.
- Sony Bank: Stablecoin payments, tokenized securities (STOs), and NFT-backed lending.
By embedding Web3 into everyday experiences — from watching a movie to attending a concert — Soneium aims to make blockchain invisible yet indispensable.
Real-World Use Cases: Yay! and Yoake Lead the Way
Soneium’s early success is evident in its ecosystem growth — over 170 projects joined within two weeks of launch. Two standout examples illustrate its user-first philosophy.
Yay!: SocialFi That Rewards Community Engagement
Yay!, a Japanese social platform with over 10 million users, leverages Soneium to reward community contributions without exposing users to blockchain complexity.
Users earn EMPL tokens for participation, redeemable for gifts or convertible to YAY tokens for cash withdrawal. Behind the scenes, all blockchain interactions are automated.
The platform supports both Web2 and Web3 users:
- Web2 users enjoy gamified rewards.
- Web3 users can stake assets, provide liquidity, and earn yield.
A recent DeFi campaign linked to Ethereum and ASTR attracted over $20 million in liquidity, proving mainstream appetite for seamless Web3 integration.
Yoake: Revolutionizing Fan Culture with Transparency
Co-developed by legendary producer Akimoto Yasushi (creator of AKB48) and Startale, Yoake is a blockchain-powered fan engagement platform.
It solves two persistent issues in fan communities:
- Vote manipulation: All voting is recorded on-chain for verifiable transparency.
- Royalty opacity: Revenue sharing from merchandise and events is automated via smart contracts.
Fans vote using social media accounts — no wallet needed. The blockchain runs silently in the background.
Yoake will launch its native YOAKE token to measure community contribution and reward loyalty — a model that could redefine entertainment-fan relationships.

Why OP Stack? Security, Scalability, and Superchain Integration
Rather than building a chain from scratch, Soneium adopted OP Stack — a decision rooted in pragmatism.
Benefits include:
- EVM compatibility: Seamless integration with existing wallets, tools, and dApps.
- Inherited security: Backed by Ethereum’s robust consensus layer.
- Developer access: Immediate entry to Ethereum’s vast coding community.
Soneium plans to join the Optimism Superchain, a network of interconnected OP Stack chains including Base and World Chain. Using the proposed Optimism Interop Protocol, chains can communicate directly — bypassing Ethereum L1 for faster, cheaper cross-chain interactions.
This interoperability positions Soneium not just as a standalone network, but as a node in a larger decentralized internet.
Astar Network: The Strategic Backbone of Soneium
While Soneium operates on Ethereum L2, Astar Network serves as its strategic counterpart on Polkadot. Despite differing base layers, their synergy is profound.
Shared Vision: Web3 for Everyone
Both networks share a mission: democratizing access to Web3. Astar’s “Evolution Stage 1.5” initiative formalizes cross-network collaboration, enabling shared liquidity, governance, and developer resources.
Using Chainlink CCIP and LayerZero, Astar and Soneium enable seamless asset and data transfer — creating a unified ecosystem across Polkadot and Ethereum.
ASTR: The Cross-Chain Value Carrier
The ASTR token plays a central role in this alliance:
- It serves as the primary asset for Soneium’s initial liquidity.
- It powers DeFi transactions, consumer payments, and stablecoin issuance on Soneium.
- It’s already standardized under ERC-7802 (SuperchainERC20) for frictionless movement across the Superchain.
As of early 2025, ASTR accounted for 57% of Soneium’s Total Value Secured (TVS) — underscoring its foundational importance.
Astar is further enhancing ASTR’s utility through:
- Astar Surge: Incentivizes liquidity provision to key Soneium dApps like Yay! and Sake Finance.
- Astar Contribution Score (ACS): A 100 million ASTR rewards program for user activity across DeFi, gaming, and social apps.
These initiatives ensure sustained engagement while positioning ASTR as a premier cross-chain asset.
Solving Latency: Fast Finality with MACH Protocol
One challenge for OP Rollups like Soneium is delayed withdrawals — up to 7 days due to fraud proof windows.
To address this, Soneium integrates AltLayer’s MACH protocol, an active validation service secured by EigenLayer’s restaking mechanism. This enables near-instant finality for games and financial services.
Critically, MACH opens a new utility for ASTR: it can be used as a network contribution asset, similar to restaked ETH, allowing holders to earn additional rewards.
Intellectual Property Protection: The Sandbox Model
Web3’s openness brings risks — particularly around unauthorized IP use. Projects like NEIRO and CHILLGUY have faced backlash over copyright issues.
Soneium responds with a balanced approach: the Sandbox framework.
Rather than outright censorship, it employs a phased review:
- Projects are monitored during a warning period.
- Suspicious contracts are flagged but not blocked.
- Access remains open via Ethereum L1 — acting as a “speed bump” against abuse.
- Developers can resolve issues and regain full status.
This model aligns with Vitalik Buterin’s concept of “soft governance” — preserving decentralization while protecting creators. It may become a blueprint for IP-safe Web3 ecosystems.
