About

joinstr.xyz and docs.joinstr.xyz describe a CoinJoin protocol using Nostr relays, with an Electrum plugin, Umbrel/web UI, daemon/CLI, Android app, and a Sparrow build with joinstr built in. FAQ says mainnet use is available and there is no coordinator taking a cut. Distinct from published Jam, JoinMarket, Wasabi, and Ginger Wallet. Do not catalog the protocol as a mixer. Whether a given pool is live on mainnet at a moment in time was not independently joined.
