Bold Bitcoin Wallet

Bold Bitcoin Wallet is an open-source Bitcoin wallet for Android. It uses a seedless setup based on a Threshold Signature Scheme, allowing wallet security to be distributed across devices rather than represented by a traditional seed phrase. The wallet is designed for users who want device-based Bitcoin signing without paper backups or hardware wallets.

The wallet can generate keys across up to three devices, with two devices required to sign transactions. Setup and signing can be completed without an internet connection. Devices communicate through a peer-to-peer encrypted protocol using Nostr or a local network or Wi-Fi hotspot.

Bold Bitcoin Wallet is compatible with PSBT signing and can work with wallets such as Sparrow and Electrum. It supports Mempool.space, either through its public service or a self-hosted instance, for advanced privacy options. The project is open-source, verifiable, and capable of offline operation.

As an Android application in the Finance & Shopping category, it is suited to users seeking a Bitcoin wallet with distributed signing and device-based control. MirrorNest distributes the official build directly from its own storage. The mirrored file is scanned for malware before publication.
