    I'm urgently looking for a fully customizable cryptocurrency wallet and funds manager written in python 3, that can safely and efficiently move funds between addresses and to and from all large CEX's and DEX's. I need this application to be customizable so that I can implement it as part of cryptocurrency trading bots that I am developing. The funds manager application should be compatible with BTC, USDT and XMR, and also allow for payments to and from legacy, bech32 and segwit btc addresses. I need to be able to send instructions to the funds manager through a command prompt as well by calling it in python applications. This project is fairly time-sensitive and I would like to have a working result within a few days if possible.
