> What wallet are you using.
There are hundreds of wallets, some of them OSS, some of them closed source, some of them homebrew. I have used several different wallets, including some that I have coded myself from lower level cryptographic APIs. This is the beauty of it: users are not limited to MetaMask, just like users are not limited to browsing the web in Chrome - despite it obviously having major market share.
And cash is a poor substitute.
