As a web extension called the
MetaMask Extension, this software wallet is accessible online. You can access this wallet using the MetaMask app, which is accessible on the official website, if you don't have a PC but do have a smartphone.
If we compare Coinbase and Coinbase Sign In then we can say that Coinbase Pro is much better than Coinbase as it comes with several unique features and new cryptocurrencies. Coinbase is also working smoothly with its wallet features. But if you are focused on exchange services only then
Coinbase Sign In would be the right choice for you.
