Seeking Technical Details

[copblockdev]

Hey, y'all!

I'm developing a wallet, which is intended to be multi-currency.

I am seeking technical details on coins.

Right now, I'm looking for ZEN( ZenCache ), Monero (XMR), Ripple (XRP), and LBRY (LBC).

Here is an example of the information I need.  It's basically to go from a HD-Key to an
address, plus information on how to connect to the network and download blocks.

Thanks in advance for any help!  Regards, Nobody

I didn't quite comprehend what designs of the wallet applications as a whole that you are trying to achieve. Integrating many coins to be able to act as a node seems an inefficient way for a wallet. It is tremendous work that is not worth the effort.

What you should do is not directly connect to the network and act as a full node, instead, you should take a look at SPV or light nodes or use the full nodes RPC. If you take a look at the Trust Wallet core codebase, which acts as a foundation for the Trust Wallet, the way the wallet works is by connecting via remote nodes[1]. So, unless you are know what you are doing, you better to think about it again.
