Introduction

Kaia Wave Stablecoin Summer Hackathon is Kaia’s first and largest flagship hackathon of 2025, built for early-stage founder teams ready to build with stablecoins.

This isn’t just another hackathon. You’ll build a DeFi MiniDapp powered by Kaia-native USDT, and we’ll help you take what you build from hack to live launch immediately after the event.

If your team wants to go beyond a weekend prototype and actually ship, Kaia Wave Stablecoin Summer Hackathon is your stage.

Who’s it for?

• Stage: Early-stage founder teams in the pre-seed to (early) seed range.
• Product Readiness: Not just a slide deck, your team should have an MVP, live prototype, or active/private beta in progress.
• Technical Depth: Demonstrated EVM ecosystem experience (Smart contracts, dApp infra). At least one strong technical founder recommended.
• DeFi Impact Potential: You’re building (or can quickly build) DeFi products that can attract and grow USDT TVL on Kaia across diverse verticals.

Why should you care?

The Kaia Wave Stablecoin Summer Hackathon is for founder teams that are ready to launch real products, not just demo an idea. Winners receive far more than prize money: they get broad, end-to-end launch support across every area needed to take a project live.

• VC introductions, investment support, and access to acceleration/incubation programs.
• Liquidity support programs.
