This library is designed to implement Tron wallet functionality with the goal of supporting offline transaction signing and API interaction with FullNode.
A small number of NodeFull APIs (which I personally use) have been added so far, looking forward to your needs. This library has implemented offline transaction signature, including the signature part of easy_transfer_by_private and get_transaction_sign functions are implemented offline and will not interact with any remote end.
Example of transferring USDT (Nile network):
iex> usdt = Tron.Contract.new "TXYZopYRdj2D9XRtbG411XZZ3kM5VkAeBf", "<YOUR_ADDRESS>"
%Tron.Contract{
contract_address: "41eca9bc828a3005b9a3b909f2cc5c2a54794de05f",
owner_address: "<YOUR_ADDRESS_HEX>"
}
iex(2)> Tron.Contract.easy_transfer_by_private usdt, "<YOUR_PRIVATE_KEY>", "TMA942pDiP7LsuhD7didyM1GpbwE9KisSU", 0.9
