Arch Network

Arch Network is Bitcoin-native financial infrastructure and a computation environment that 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 first-party TypeScript and Rust SDKs, a CLI, and an AI agent kit. Surfaced as a portfolio company of Multicoin Capital.

Arch Network is profiled on the APIs.io network. Tagged areas include Company, Crypto Web3, Bitcoin, Blockchain, and DeFi.

Arch Network’s developer surface includes documentation, getting-started guide, engineering blog, support, changelog, CLI, and 7 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/arch-network: open an issue to ask a question, or submit a pull request to add artifacts.
