Apex SDK Protocol

[kherldhussein]

Project Abstract

Apex SDK Protocol is a unified Rust SDK that provides compile-time safe, ergonomic APIs for multichain development, focused on Polkadot's hybrid parachains (Moonbeam, Astar) and Substrate-EVM interoperability. By composing subxt and alloy into a single consistent interface, it eliminates toolchain fragmentation, reduces hybrid integration time from weeks to days, and enables faster production of cross-chain applications such as DeFi protocols, indexers, arbitrage bots, and asset management tools.Building on the existing v0.1.4 release, the project delivers enhanced cross-chain primitives (including XCM support), comprehensive documentation, tutorials, and community tooling to accelerate Rust developer onboarding and drive growth across Polkadot's parachain ecosystem.
