MyEtherWallet, a wallet to store ether and its derivatives from the ethereum network, is very complete in that it requires transferring balances or simply storing and managing assets, for which it is highly recommended, as for the MEW feature, it is an interface executed on the client side, which interacts with the Ethereum blockchain and serves to generate purses. In this sense, it is worth noting that these purses are not connected to the internet, that is, they are cold purses, since although they are created on the web, all information and funds are not saved on MEW servers, but on one's computer.
