What is Wallet of Satoshi
Wallet of Satoshi (WoS) is a Bitcoin and Lightning wallet app for iOS and Android made by the Australian company Wallet of Satoshi Pty Ltd. It started as a fully custodial wallet and now also offers a self-custodial mode powered by Lightspark's Spark layer 2; the app assigns the mode by region.
