Could you elaborate on the concept of WEMIX Wallet? I'm curious to understand its functionality and how it fits into the broader cryptocurrency and finance landscape. Specifically, I'd like to know if it's a multi-asset wallet, whether it supports decentralized applications, and how secure it is. Additionally, is it compatible with various blockchains, and does it offer any unique features or benefits that set it apart from other wallets? A detailed description would be much appreciated.
