As the world of Web3 continues to evolve, one truth remains clear: strong communities shape the strongest protocols. That’s why INTMAX is proud to return as a sponsor of ETH Kyiv, supporting the Ukrainian developer ecosystem for the second year in a row. INTMAX honored Ukrainian hackers with a $10,000 prize.

Why Ukraine Matters

Ukraine has shown time and time again that it’s home to one of the most resilient and forward-thinking developer communities in the world. Despite immense challenges, Ukrainian builders have stayed at the forefront of innovation — pushing boundaries in privacy, scalability, and real-world use cases.

We at INTMAX see these builders as true early adopters. Not just of new technologies, but of new values: decentralization, freedom, and privacy. That’s why we’re honored to share our protocol with them again this year.

What is INTMAX?

INTMAX is a stateless zkRollup designed to bring real privacy and scalability to Ethereum. Unlike traditional rollups, INTMAX uses zero-knowledge proofzs and local storage to minimize on-chain data — requiring just ~5 bytes per sender. This makes it a powerful foundation for real-world applications that demand both speed and confidentiality.

Whether it’s:

• Cross-border payments

• Private voting

• Anonymous donations

• Programmable payments

INTMAX is built to handle it — without compromising on decentralization or user freedom.

Insights from Our Workshop: June 13

On June 13 (17:15–18:00), the INTMAX team hosted an in-person workshop at ETH Kyiv, diving into how developers can integrate privacy and scalability into their apps with INTMAX.

Hackathon Highlights:

One of the highlights of ETH Kyiv was the amazing lineup of hackathon projects built by participants leveraging the INTMAX protocol. These builders showed what’s possible when privacy and scalability meet real-world needs.

INTMAX Proof of Identity tackled the compliance-privacy paradox. Traditionally, verifying users against sanctions or terrorist watchlists requires exposing sensitive personal data. This project introduced a zero-knowledge proof-based AML tool that allows users to prove they’re not on a blacklist — without revealing their name, birthdate, or passport data. It’s a breakthrough in enabling private yet compliant onboarding for dApps and payments on INTMAX.

ShadowPay built a secure queue-based payment system using INTMAX’s private transaction infrastructure. With a unique “kiosk mode”, it ensures users can interact with payment terminals in public settings — without compromising privacy. The team even overcame technical hurdles by adapting INTMAX’s SDK to work with a Next.js environment, demonstrating true builder resilience.

senditAI brought voice to crypto. Their solution enables fully hands-free crypto operations — sending tokens, requesting payments, or checking balances — just by speaking. It turns the wallet into an AI-powered voice assistant, making decentralized finance more accessible and intuitive than ever.

Looking Ahead

At its core, INTMAX isn’t just a protocol — it’s a movement. A movement for a freer, fairer digital world where users own their data and developers aren’t forced to compromise between privacy and performance.

We believe Ukraine will be a key part of that future, and we’re here to build it together.

It was pleasure to see you in Kyiv.
