INTMAX, the next-generation protocol for all payment infrastructure and mathematically proven optimal solution, launches on Ethereum mainnet.
Zug, Switzerland – June 26, 2025 – Ryodan Systems AG today officially announces the mainnet launch of Intmax, an Ethereum layer that redefines Layer 2. With an entirely new architecture and a radical stateless design that minimizes on-chain data, Intmax enables ultra-low-cost and privacy-preserving payments on Ethereum even under heavy network congestion.
The Highly Anticipated Ethereum Layer 2 Solution
The breakthrough behind Intmax lies in the Plasma architecture, a concept first spotlighted in 2017. While Plasma was ultimately deemed infeasible, Intmax has now overcome its technical limitations and is the first protocol to realize Plasma’s vision in practicality. Intmax stands as proof that Plasma’s lightweight, secure, and decentralized design is the most sustainable and universal approach. While most Layer 2s pursue scalability through compression and off-chain execution, Intmax adopts a fundamentally different approach, requiring just ~5 bytes of on-chain data per transaction, while remaining fully secured by Ethereum.
Privacy Mining: A New Model for a Private Future.
Intmax introduces INTMAX Privacy Mining, a novel incentive mechanism rewarding users for contributing to network privacy. This creates a synergy of anonymity and incentives, supporting a healthy, decentralized ecosystem and upholding both universal accessibility and the fundamental right to privacy.
The ITX Token: Private by Default, Compatible with DeFi
The ITX token exists in two forms:
- Layer 2: As a fast, private, native asset used for real-world payments.
- Layer 1: As a standard ERC-20 token compatible with DeFi platforms and exchanges.
This dual nature gives ITX unique power — allowing Ethereum-based capital to access privacy and performance without leaving the broader ecosystem.
Endorsed by Ethereum Core Researchers
The innovative architecture of Intmax has received strong support from Ethereum core community:
“So, in some sense, Intmax is even more efficient than ZKRollup… One of the really cool things is that the chain is actually not verifying SNARKs until the very end when you withdraw.” — Justin Drake Watch here
“Another class of constructions is hybrid plasma/rollups, such as Intmax. These constructions put a very small amount of data per user on-chain (e.g. 5 bytes), and by doing so, get properties that are somewhere between plasma and rollups.” — Vitalik Buterin Read here
The global cryptocurrency payment market is experiencing rapid expansion, with projections indicating a growth of USD 4.82 billion by 2030. However, this growth also increases the exposure of sensitive financial data, thereby compromising user financial privacy. INTMAX addresses this by providing an ideal platform for high-volume Ethereum payments, including remittances, payroll, and cross-border settlements. Intmax also preserves user privacy by design. Sensitive data such as transaction history or account balances never appear on-chain, enabling a truly secure and private digital cash experience for everyday use.
Comments from the Founders
Leona Hioki, Co-Founder
“After a long technical struggle, I’m truly delighted to finally bring this to the world. It’s been quite some time since I first joined the Plasma research effort. This journey to scale Ethereum presented many possible answers, and along the way, we had the freedom to choose among them. But our relentless desire—for both privacy and near O(1) scaling—pushed us to ignore those options and instead create this new address space: Intmax. I hope you’ll also make good use of this mysterious realm where every transaction is incredibly lightweight—and everything is private.”
Mai Fujimoto, Co-Founder
“I’m truly grateful to have reached the mainnet launch. I believe blockchain should be freely usable by all, not just the wealthy due to congestion and high gas fees. This led to INTMAX’s creation. Everyone deserves the fundamental property right to protect and move their assets freely, and privacy is crucial for self-protection. I hope INTMAX will become the foundation that delivers choice and dignity to more people around the world.”
