Odaily Planet Daily reports that Bitcoin News posted on X that EntropyLab has released the first candidate version, v1.0.0rc1, of its self-contained Bitcoin key and wallet calculator. The application runs as a single HTML file, requires no internet connection, and does not generate entropy on its own; users can provide their own entropy to calculate keys and wallets in a completely offline environment.
This tool supports multisignature, PSBT, BIP-85, Silent Payments, vanity addresses, watch-only wallet export, and nonce analysis. This version is reproducible and can be verified by signatures from four independent signers; the team recommends users download and verify the files before transferring them to an air-gapped computer, as the official v1.0.0 release is pending completion of candidate version testing.
