Please add the definition of other networks

please at least support ETH and USDT

At present, bitcoin and litecoin are very convenient to try out in the production environment (but ETH and USDT are implemented with other libraries), thank you in advance, maybe later versions add ETH and USDT👍👍👍

Is there any blocking reason not to merge BCH & BCHSV networks definitions in release?
Thanks

I don't think those networks have enough stable and good working Blockchain service providers. Without a good API backend the library doesn't work as expected.
