The System Chain Standard Library
Build specialized, high-performance apps for Polkadot Asset Hub, Revive, and PolkaVM
Apex SDK is the open-source standard for system chain development. Type-safe APIs, blazing fast Rust performance, and unified tooling for the next generation of Polkadot builders.
Core Features of Apex SDK
Everything you need to build production-ready cross-chain blockchain applications
Native Asset Hub Integration
High-level APIs for managing assets, NFTs, and balances on Polkadot Asset Hub. Seamless integration with system parachains.
Asset Hub Guide →Enterprise-Grade Security
Built-in security best practices, audit trails, and secure key management for production deployments.
Security Guide →Revive Protocol Support
Native support for the Revive protocol, enabling asset recovery and cross-chain migration patterns unique to Polkadot.
Revive Integration →PolkaVM & Solidity Contracts
Deploy and interact with Solidity smart contracts on Polkadot Asset Hub using the high-performance PolkaVM backend.
Contract Manager API →Modular Crate Architecture
Apex SDK is built with a modular, crate-based architecture. Only include the modules you need for your specific system chain.
Installation Guide →Production Ready
Battle-tested in production environments. Comprehensive testing suite with 119+ passing tests.
Testing Guide →Polkadot System Chains & Beyond
Built specifically for the Polkadot ecosystem. Apex SDK provides a unified interface for Asset Hub, Revive, and the entire relay-parachain matrix.
