The definitive Rust framework for Multichain Development
Apex SDK is the enterprise-grade Rust framework for building production-ready blockchain applications across 15+ networks. One unified API for EVM and Substrate ecosystems.
The Definitive Toolkit
Engineered for developers who demand absolute type-safety, performance, and cross-chain agility.
Absolute Type Safety
Rust's legendary type system, extended to every chain. Catch ABI mismatches and RPC errors at compile time.

}Unified Pipeline
Write once. Our pipeline handles nonce, fees, and finality tracking across 15+ networks.
sdk.execute(tx)
.with_retry(3)
.await?;Global Interop
Native XCM & EVM bridge support built directly into the core runtime.
Pro Tooling
Advanced CLI for contract transpilation, local testing, and multi-signature orchestration.
Technical Architecture
A high-fidelity schematic of the Apex SDK core. Engineered for deterministic performance and cross-chain scale.
Deterministic Orchestration
High-concurrency transaction pipeline with guaranteed atomic commitment via tokio.
Native Translation
Zero-overhead serialization for Substrate (SCALE) and EVM (RLP) protocols.
Asynchronous I/O
Non-blocking connection pooling with intelligent failover and circuit breaking.
One SDK. 15+ Networks.
Seamlessly navigate the fragmented multichain landscape. Apex SDK provides the unified gateway to the industry's most powerful blockchains.
