Mixin is an open-source cryptocurrency wallet combined with a messenger built on the Signal Protocol.

The same group of products extends beyond the messenger into custody and trading infrastructure. Mixin Safe is a Bitcoin custody service that uses timelock technology from Bitcoin Script. Mixin Route offers decentralized ways to trade cryptocurrencies. Privacy Wallet is an MPC self-custodial wallet, and Custody is a self-custodial multisig cold wallet aimed at families and businesses. The site names multisig and MPC as the underlying technologies.
