Cake Wallet allows you to safely store, exchange, and spend your Monero, Bitcoin, Litecoin, and Haven. Cake Wallet is focused on an excellent transaction experience.
Besides shilling a shitcoin, that is Haven, I wouldn't trust the skills of a developer who chooses to work on creating a closed-source Bitcoin, Monero and Litecoin wallet, not only for his intentions, but for the fact that he's likely to mess things up, and he did apparently. Open source projects that focus on just one cryptocurrency, and who're reviewed by literally hundreds of developers (such as Electrum) do have some issues presented every now and then. Let alone a brand new, closed-source, multi-crypto environment.
honestly, i would personally want to avoid any entropy scheme that relied on a hashing function. shouldn't be necessary.
Honestly, I don't understand why they're passing the entropy through a hash function, and I wouldn't want it either. But, does it harm? Very little according to StackExchange. Essentially zero.
