I am new to this erea and I am trying to write a wallet application.
I have developed my wallet to publish on
Ethereum and can now publish to ETH
I am wondering if I can add some more coins to my wallet app which are compatible to this chain, since they don't need much development, like Shiba which is a smart contract on ETH network.
Now, my question is, how can I find more coins like Shiba which are developed and work well on ETH network? and how can I find a
testnet to check my development for those coins? (How to setup a development environment for those coins?)
