[QUESTION] How to integrate it into a pure CPP environment

[tolstenko]

Is your feature request related to a problem? Please describe.
I am new to this project and I feel it lacks a more detailed CPP example.

Describe the solution you'd like
A better CPP example containing

• How to submit the raw transaction to an RPC (curl? cpr?)
• How to estimate gas from a transaction
• Call contract function using the ABI and Bytecode

Describe alternatives you've considered

• https://github.com/ethereumproject/cpp-ethereum is deprecated
• I came from ethersjs, so obviously I am biased, but for now, the easiest example I found to do what I need in CPP is yours. https://github.com/trustwallet/wallet-core/blob/master/samples/cpp/sample.cpp
• The options I had in mind is to create a side-car or even embed nodejs(ethers) or go(geth) into CPP in order to achieve what I need but it seems too naive.

Additional context

• I am developing a game in CPP and I am looking for solutions to embed a wallet and execute contract transactions inside the game. The easiest example so far in CPP is yours.

Reference:

• You can see here, CPP doesn't have any maintained client support. https://ethereum.org/en/developers/docs/nodes-and-clients/#execution-clients
  

Thanks for your time.

Communication to RPC nodes is outside of the scope of wallet-core, though of course it is an important part of a full product.
Broadcasting a prepared Eth transaction to an RPC node is quite easy, a simple google search and a curl command can do it. In fact one does not even need a curl command, etherscan has a built-in function to broadcast a transaction.
