Alpen Labs

Alpen Labs is a Bitcoin infrastructure company building Alpen (formerly Strata), an EVM-compatible zero-knowledge validity rollup on Bitcoin that lets developers deploy standard Solidity smart contracts and applications settled to the Bitcoin base layer. The developer surface is a public JSON-RPC interface: an Ethereum-compatible full node exposing standard eth_* methods, twenty-five Strata-specific strata_* methods, and an ERC-4337 account-abstraction bundler (EIP-7769). Developers get a testnet (chain ID 8150, Signet BTC), a PoW faucet, a block/checkpoint explorer, and the first-party Rust alpen CLI for wallet, deposit, withdraw and bridge operations. Backed by Ribbit Capital.

Alpen Labs publishes 1 API on the APIs.io network. Tagged areas include Company, Crypto, Bitcoin, Blockchain, and Rollup.

Alpen Labs’ developer surface includes documentation, API reference, getting-started guide, engineering blog, support, CLI, sandbox, and 9 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/alpen-labs: open an issue to ask a question, or submit a pull request to add artifacts.
