It is a wallet which only exchanges or trades coins with the Ethereum platform, it is open source, it has been made simple, easy, comfortable to work with, this application has a high level of security since it has a backup every 30 seconds . It does not keep keys in the blockchain, it is stored in the device it uses. However it does not provide 2 levels of security but so far there have been no security issues. Besides it is fabulous since it maintains my anonymity in the transactions. It is an excellent wallet that only stores Ethereum. It was super if this application could also store other currencies that are not in the Ethereum network.
