Astar, a web3 collective based in Japan, has relaunched its digital collectible game Yoki Origins under a new title, Yoki Legacy, on Sony's Soneium blockchain. The move marks a strategic shift aimed at expanding accessibility and continuing the development of the Yoki intellectual property in a blockchain ecosystem designed to support creative and IP-focused applications.
Yoki Legacy x Blockchain
Yoki Origins originally debuted last year on the Astar Network, Japan's leading web3 ecosystem, with involvement from major partners including Casio, Japan Airlines, JR Kyushu Railway Company, Quickswap, and Rarible. The project drew significant user engagement, pulling in 59,000 unique wallet addresses and the minting of 2.5 million Yoki-related non-fungible tokens (NFTs).
Now hosted on Sony's Soneium blockchain, a Layer 2 network developed by Sony's Block Solutions Labs, Yoki Legacy aims to reach broader audiences and support long-term scalability. Maarten Henskens, head of Astar Foundation, stated that the transition to Soneium aligns with Astar's mission to preserve and expand the Yoki IP in an environment designed to empower creators and projects centered on intellectual property.

Streamlined Gameplay and Token Integration
Yoki Legacy keeps the core gameplay of its predecessor but introduces a simplified structure meant to improve user experience. Drawing inspiration from Pokémon and traditional Japanese culture, the game lets players collect digital characters called "Yokis" and fill out a virtual notebook. In this updated version, the Yoki count drops from 48 to 24, split into 12 basic and 12 evolved variants. Players fuse three identical basic Yokis to create an evolved one, keeping the strategic element while making the game easier to approach.
The game also introduces a revised token system. The original in-game token, previously called Omamori (OMA), has been rebranded as OMASTR to reflect tighter integration with the Astar Network. Players can mint OMASTR tokens on Soneium using Astar's native token, ASTR, with no daily limits. This change gives users more flexibility and encourages participation across the ecosystem.
OMASTR tokens are primarily used to obtain Yokis through capsule machines, the game's core mechanic. There are now three distinct capsule machines, each featuring different Yokis and offering four capsule types. This variety creates opportunities for players to collect different character sets and stay engaged over time.
Incentives to Support Web3 Engagement
As part of the relaunch, Astar Foundation has expanded its Astar Contribution Score (ACS) program, which rewards users for participating in on-chain activities. Players earn ACS Points by minting Yokis, fusing them, and completing their notebooks. The program is backed by a reward pool of 100 million ASTR tokens, with two million ACS Points available at launch and the potential for more allocations later.
To encourage participation, players who complete their Yoki notebook by June 1 will receive an exclusive Yoki OG Badge. Developed through the collaboration between Astar and Sony's Soneium, the badge represents early engagement and support for the project. Sony noted that this badge goes beyond a digital item, symbolizing a user's contribution to the development of the Soneium blockchain ecosystem.

Positioning for Future Growth in Web3
With Yoki Legacy now live on Soneium, Astar and Sony are using the strengths of both organizations to build a more engaging and scalable web3 gaming experience. Soneium launched with support from established technology providers including Circle, Optimism, Alchemy, The Graph, and Chainlink, and is built to host decentralized applications across gaming, entertainment, and finance.
By moving Yoki Legacy to this infrastructure, Astar is setting up the game and its IP for long-term growth while continuing its broader mission of driving adoption and innovation in the web3 space.
