INTMAX is a next-generation Ethereum Layer 2 solution designed for ultra-scalable and privacy-preserving payments. Unlike traditional rollups, INTMAX is a stateless zk-rollup that uses a radical architecture inspired by Plasma but rebuilt with modern zero-knowledge proofs. It enables transactions with as little as ~5 bytes of on-chain data per user, making it highly efficient even under heavy network congestion.
INTMAX prioritizes:
- Privacy by default – transactions are unlinkable and off-chain
- Constant Near-zero gas fees – no matter how many users are transacting
- Decentralized scalability – without compromising Ethereum security
It also introduces Privacy Mining, an innovative incentive system that rewards users for helping others stay private — turning privacy into a public good.
INTMAX supports developers through its Developers Hub, offering ecosystem grants, technical advisory, business growth support, and access to funding and marketing resources.
