About this resource.

Who operates this website?

Bitcoin Labz is operated by KeychainX, which also offers commercial wallet recovery services. Links to those services reflect that relationship. The site is independent of the software projects discussed here.

Attribution

Software names identify their respective projects. We link to original documentation and repositories rather than presenting those projects as KeychainX products. Three original Python exercises are tested with synthetic inputs. The regtest note is documentation-based and separately labeled.

Editorial and testing limits

This edition was prepared with AI assistance for KeychainX. The linked references were consulted on 20 September 2026. The 3 downloadable Python exercises were executed locally on 20 September 2026 with the supplied invented inputs and built-in assertions. No client wallet was used. This tests those examples, not a real recovery workflow.

The historical pyethrecover program and Bitcoin Core regtest procedure were not executed as part of this publication. We make no claim of an independent security audit, guaranteed compatibility, measured recovery speed or guaranteed recovery result.

Privacy
