Overview

The INTMAX Client SDK provides a secure, high-performance interface for interacting with the INTMAX network. Built with WebAssembly for optimized cryptographic processing, the SDK abstracts complex blockchain operations into a developer-friendly API that handles the complete transaction lifecycle—from creation and signing to broadcasting. This documentation covers the SDK's core functionality, available functions, and interface specifications to help developers build secure blockchain wallet integrations with confidence.

Latest Version: 1.4.1

⚠️ Mainnet is not supported yet. Please use the Testnet.

Architecture

This section outlines the core workflows supported by the INTMAX network: Deposit, Transfer, and Withdrawal. Each workflow is carefully designed to ensure security, scalability, and seamless interaction between Ethereum mainnet and INTMAX network.

Deposit Workflow

Transfers assets from the Ethereum mainnet to INTMAX network. A Predicate contract blocks deposits originating from sanctioned addresses, preventing illicit funds from entering INTMAX network. Deposit data is then relayed to the Scroll network via the Scroll Messenger, preserving maximum security throughout the process.

Transfer Workflow

A user-signed transaction is packaged as a single transfer and submitted to the Rollup Contract by the Block Builder.
