Courses, books, guides, comparison sites and nonprofit resources that teach Bitcoin self-custody, key management and inheritance planning.

Privacy & Coinjoin

An open-source, self-custodial Android Bitcoin wallet built for privacy by design. It supports Zerolink Whirlpool coinjoins, BIP47 PayNym reusable payment codes, connection to your own Dojo node over Tor, coin control with labelling and freezing, batch spending and a decoy stealth mode. Released under GPLv3.

Education & Resources

Bitcoin Core is the reference implementation of the Bitcoin protocol, and its site hosts release notes, security advisories, RPC documentation for every recent version and contributor guidance. It is the primary source for anyone running or building on their own full node.

Multisig & Collaborative Custody

Bitcoin Keeper is an open-source mobile wallet built around multisig self-custody, developed by BitHyve. It lets users assemble vaults from multiple hardware and software signers while retaining full control of their keys.

Software Wallets

Bitcoin-Safe is free and open-source desktop software for managing bitcoin cold storage wallets, built on the Bitcoin Development Kit. It requires a hardware signer and provides a modern interface for single-signature and multisig cold storage across Windows, macOS and Linux.

Hardware Wallets

Bitkey is a bitcoin-only 2-of-3 multisig wallet combining a hardware device, a mobile app key and a server key, so there is no seed phrase to write down. The design includes built-in inheritance and recovery flows while the owner keeps control of spending.

Software Wallets

BlueWallet is an open-source mobile and desktop bitcoin wallet that includes a Multisig Vault feature alongside standard and watch-only wallets. Keys never leave the user's device, so the vault is fully self-custodial.

Multisig & Collaborative Custody

Casa provides multi-key self-custody for bitcoin using keys spread across several devices and locations, so no single device failure loses access. Plans add white-glove security guidance, inheritance planning and recovery support while the customer keeps control of their own keys.

Software Wallets

Electrum is a long-running open-source bitcoin wallet that supports multisig wallets, splitting the permission to spend coins between several wallets. It also supports cold storage with watch-only wallets, hardware devices and third-party multisig service plugins.

Hardware Wallets

Krux is open-source firmware that turns off-the-shelf Kendryte K210 devices into airgapped bitcoin transaction signers, commonly used as one of the signers in a multisig setup. It also provides tooling for creating, encrypting and recovering mnemonic backups.
