INTMAX is a stateless Layer 2 protocol built on Ethereum, designed to provide scalable, private, and low-cost transactions. It aims to enable high-speed, confidential transfers while allowing users to maintain self-custody of their assets ^[1].

Overview

INTMAX is a stateless Layer 2 solution for Ethereum that combines Plasma architecture with zero-knowledge proofs to improve privacy and scalability ^[1]. It separates client-side data handling from blockchain execution, aiming to lower transaction costs and enhance privacy without compromising security ^[2]. The system is designed to support efficient digital asset transfers, especially for use cases requiring speed and low fees ^[1].

INTMAX emphasizes optimized value transfers rather than general-purpose smart contracts, enabling features like multi-token distribution to multiple addresses in a single transaction at no extra cost ^[2]. While it does not support EVM compatibility, its architecture prioritizes performance and cost efficiency, making it a focused solution for users seeking streamlined and secure token transfers ^[2].

The INTMAX testnet was actively deployed on Ethereum’s Sepolia Network as of December 16th, 2023 ^[2].

Architecture

INTMAX is a Layer 2 protocol on Ethereum that adopts a stateless architecture ^[1]. This means it doesn’t require validators or nodes to store the full state of all accounts or contracts ^[2]. Instead, it handles computation and state management off-chain while posting only essential data—such as nullifiers and a validity proof—on-chain ^[3]. This design drastically reduces the on-chain data footprint and supports higher scalability and lower transaction costs ^[1].

At the core of INTMAX’s design is zero-knowledge proofs (ZKPs), which allow off-chain computations to be verified securely without revealing sensitive information ^[1]. By using short identifiers (around 4–5 bytes) and an interactive protocol for nullifier generation, INTMAX minimizes data per transaction ^[1]. Its architecture blends elements of ZK-rollups and Plasma, combining ZKPs for trustless computation with mechanisms that improve on Plasma’s historical issues like complex exits and data availability ^[1]. The protocol inherits security from Ethereum Layer 1 and aims to deliver a more efficient, privacy-preserving transaction layer ^[2].

The network utilizes various nodes and smart contracts, including Block Builders, Store Vault Servers, Deposit Relayers, Withdrawal Servers, Withdrawal Aggregators, Claim Aggregators, Withdrawal Relayers, Indexers, and Validity Provers ^[4]. The Block Builder node is responsible for submitting validated blocks to the network, contributing to decentralization and robustness ^[5].

Products

Privacy Mining

Privacy Mining is a system developed by INTMAX to promote and reward private, trace-free crypto transactions ^[6]. Participants earn ITX tokens by conducting privacy-preserving actions on the network, such as depositing and transferring ETH without revealing metadata or linking addresses ^[7]. The mechanism operates with minimal fees and emphasizes anonymity, allowing users to contribute to the network's privacy infrastructure while being compensated for their activity ^[6].

The process runs on the Base chain and is accessible with just 0.1 ETH and a computer ^[7]. Rewards are distributed using a fixed-supply schedule of 1,001 million ITX tokens over a structured 2,032-day halving cycle, which began in November 2024 ^[7]. Privacy Mining was initially available via a CLI, with an enhanced web UI/UX interface released by Q1 2025, making it accessible to non-technical users ^[7]. Early participants using the CLI received higher incentives ^[7]. The system incentivizes individual privacy and strengthens the network’s Anonymity Set through collective participation ^[7]. INTMAX supports mainstream assets like ETH, WBTC, DAI, and USDC for private transfers ^[6].

INTMAX Wallet

The INTMAX Wallet is a mobile-first, browser-compatible crypto wallet focused on high-level security and ease of use ^[8]. It employs advanced cryptographic techniques such as Multi-Party Computation (MPC) and Fully Homomorphic Encryption (FHE) to protect assets and enable secure, private transactions without compromising usability ^{[8] [3]}.

Users can send crypto via simple links, bypassing traditional address inputs, and access their wallet from any device without requiring extensions, apps, or seed phrases ^[8]. The wallet supports encrypted account sharing across devices, allowing seamless access and continuity ^[8]. Its design offers security levels comparable to hardware wallets, aiming to provide a cost-effective yet secure alternative for managing digital assets ^[8]. The wallet supports various networks including Ethereum, Polygon, Optimism, and Arbitrum, and over 750 tokens ^[8].

In May 2025, INTMAX Wallet integrated on-ramp and off-ramp capabilities through a partnership with Unlimit, a fiat-crypto payment infrastructure provider. This allows users to buy and sell crypto using local fiat currencies in over 30 countries across LATAM, APAC, Africa, Europe, and India ^[9]. The on-ramp and off-ramp features were initially available in the web version of the wallet ^[9].

The wallet is described as a "walletless wallet" because it uses keyless authentication methods like social logins, biometric verification, or ZKPs to authenticate transactions without requiring users to store private keys or on-chain accounts directly ^[3]. This approach leverages off-chain computation and technologies like MPC and FHE to enhance security and user experience, although it introduces considerations regarding centralization risk if relying on third-party services ^[3].

ITX

ITX is the native token of the INTMAX Layer 2 network, designed to reward users who engage in privacy-preserving activity through mechanisms like Privacy Mining ^[10]. It is earned through adherence to unlinkability rules, rather than distributed via traditional airdrops ^[10]. Beyond its role as a reward, ITX may serve future functions such as enabling access to private transactions, participating in governance, and providing utility within privacy-focused applications ^[10]. As demand for private, trace-free infrastructure grows across crypto, finance, and AI systems, ITX is positioned as a token tied to that emerging need ^[10]. The token has a fixed supply of 1,001 million tokens ^[7].

Developer Tools

INTMAX provides several tools for developers to interact with the network:

• INTMAX Client SDK: A comprehensive solution for creating, signing, and broadcasting digital transactions, offering simplified API access ^[2].
• INTMAX CLI: The official command-line interface for managing digital assets, performing batch transfers (up to 63 transactions simultaneously), monitoring transaction statuses, and participating in privacy mining operations ^[2].

Partnerships

INTMAX has established partnerships across various sectors to expand its ecosystem ^[11]:

• Payments: INTMAX Wallet, Payless by INTMAX, Plat’Home, 3AM Japan K.K. ^[11].
