EntropyLab releases an offline Bitcoin wallet tool that supports completely air-gapped key generation.

BlockBeats news, October 3rd, Bitcoin offline key tool EntropyLab has released its self-contained Bitcoin key and wallet calculation tool v1.0.0rc1, which is the project's first release candidate. The tool runs entirely within a single HTML file, requires no network connection, and does not generate random entropy itself; users must provide their own entropy and can calculate Bitcoin keys and wallets in a fully offline environment.

The tool supports multisig, PSBT, BIP-85, Silent Payments, vanity addresses, watch-only wallet export, and Nonce analysis, among other features. EntropyLab states that this version is reproducible and can be verified through signatures from 4 independent signers.

The team recommends that users first complete verification after downloading the file, then transfer it to an air-gapped computer for use. Currently, the official v1.0.0 version has not yet been released, and the project team is testing this release candidate.
