Japan Smart Chain at ETHTokyo!

Japan Smart Chain (JSC) will be joining ETHTokyo 2025 as a Platinum Sponsor, taking place in Shibuya, Tokyo from September 12–15, 2025. As web3 developers and innovators from around the world gather at this premier event, JSC will showcase the following initiatives:

[Presentations & Workshops]

On the main conference day, September 12,  we will host a presentation and on the first day of the hackathon, September 13, we will hold a workshop where participants can experience the JSC Testnet and Mizuhiki Identity firsthand. See for yourself how our compliance-first solutions can be applied to real-world use cases.

[Hackathon]

One of the highlights of ETHTokyo 2025 will be the EthTokyo hackathon held from the 13th to the 15th, where we will be supporting hackers to build on the JSC Testnet “Kaigan.”
Theme: Compliant Ticketing and DeFi using Mizuhiki ID

🏆 Total Prize Pool: US$3,500

🥇 Ticketing application – US$1,500
🥇 Privacy-preserving DeFi application – US$1,500
💎 One Special Award – US$500 for a unique idea that, while not fully developed into a winning solution, strongly resonates with JSC’s mission.

One of the most exciting prizes - beyond cash - is the opportunity to pitch directly to JSC Founders and Investors shaping the web3 space. This is your chance to turn a weekend project into a commercially viable idea - gaining visibility with the people who can help you take it to the next level.

[Booth & Community Engagement]

During the event, we’ll also host a booth where participants can receive original JSC swag by joining the hackathon or following JSC on X and Discourse. Our team members will be there to welcome your ideas, feedback, and questions—we look forward to engaging directly with the community.

Building Japan’s Next-Generation Ecosystem Together

Through our Japan-sovereign blockchain infrastructure and the modular trust suite Mizuhiki, JSC aims to build the foundation for a new digital society ecosystem. ETHTokyo 2025 is the perfect opportunity to share that vision and start new collaborations.

We can’t wait to meet you in Shibuya soon!
