# Arch Network

> Bitcoin-native financial infrastructure and computation environment. Arch lets developers build
> DeFi and capital-markets applications — lending, yield, trading, and structured products — with
> settlement kept local to Bitcoin. It executes programmable smart contracts (written in Rust) over
> Bitcoin UTXOs using a specialized virtual machine and threshold-cryptography (FROST/ROAST)
> validator security, and exposes a JSON-RPC API with TypeScript and Rust SDKs, a CLI, and an AI
> agent kit.
