How does the Blockchain component work?

I’m trying to create an Ethereum wallet app in Thunkable and was wondering if I could use the Blockchain by Oasis component. Does this component work with just ethereum or all ERC20 tokens? And how do I show the balance for each token separately?

i am really interested in developing dapps or apps with blockchain technology, but ethereum it´s slow, expensive and closed-minded, i am looking for alternatives like eos.
What do you want to build?

I’m trying to build a simple ethereum-only wallet
