"Apple (AAPL) has rejected the latest version of non-custodial Lightning-enabled bitcoin wallet Zeus, according to a tweet by Zeus founder Evan Kaloudis.

This comes a day after Apple’s spat with another popular Lightning-enabled bitcoin app – Damus, a decentralized social media platform that runs on the Nostr protocol (Nostr is an acronym for “notes and other stuff transmitted by relays”). According to tweets from Damus, Apple took issue with the Damus’s “zap” feature, which allows users to send small amounts of bitcoin over the Lightning Network to their favorite content creators as a token of their appreciation, much like Twitter’s “tip” feature. Lightning is Bitcoin’s second layer payment network for cheaper and faster transactions.

Apple has now turned its attention to Zeus, asking the wallet’s creator to provide proof of requisite licenses and permissions for approval to facilitate transmission of a virtual currency or face rejection by Apple’s App Store, according to Kaloudis. Zeus is apparently in violation of Apple’s guidelines which require apps to provide proof of appropriate licenses – such as money transmitter licenses – in order to facilitate the “transmission” of cryptocurrencies."
