Hey, great article.
I would like to add another wallet to the OpenSource wallets list, the name is Atomic Wallet.
https://atomicwallet.io/https://github.com/Atomicwalleti have been using this wallet in the past months and is the best one i have ever seen. It has features like swap, buy cryptos, staking, and multiple coins and tokens wallet... So far so good, and i think it deserve a mention in this thread.
While they use open-source library on their wallet, the wallet itself is closed source. If you take a look at their GitHub page, their repository only consist forked repository of open-source library.
