Nunchuk
freemium · open sourceNunchuk is a multisig Bitcoin wallet designed around inheritance and shared custody: setups where a spouse, partner, or heir holds one of the keys. The core apps are open source and free, and a basic multisig needs no one's permission. Paid plans add assisted services where Nunchuk's server acts as a backup co-signer, which is convenient but puts a company back in the loop.

Trust-minimized
The free multisig is fully yours; opting into paid assisted-key or inheritance services places Nunchuk's server among your co-signers.

Bisq
Bisq is a desktop application for buying and selling Bitcoin directly with other people over Tor — no accounts, no identity checks, no company holding your money. Trades settle peer-to-peer with security deposits and escrow protecting both sides. The honest tradeoff: you pay a premium over exchange prices and trades move slower. Privacy and permissionless access are what you are buying.
RoboSats
RoboSats is a peer-to-peer exchange for buying and selling Bitcoin over Lightning, designed so trades clear in minutes under throwaway robot identities instead of accounts. Lightning hold invoices protect both sides while a coordinator referees each trade, which means some trust in that coordinator — though you can choose between several. Expect a price premium in exchange for the privacy.
Specter Desktop
Specter Desktop is open-source software for coordinating multisig Bitcoin wallets against your own node. Multisig means spending requires several keys held on separate devices, so no single theft, fire, or mistake loses your coins. Specter handles connecting hardware wallets and building the setup. It assumes you already run a node and own signing devices — a later rung, not a first step.
