Hi Peachy, I had the exact same problem and couldn’t figure it out so just created a development wallet using Stuart’s script here: [Development Wallet Creation](https://radixtalk.com/t/how-to-create-a-radix-wallet-for-development-purposes/61)

This will allow you to create the necessary hex encoded keys to play around with txs using the API.

I believe 0xOmar in Discord has also created a python library that can extract the private key from the desktop wallet seed, so you could look into that if you want to use the desktop wallet created address.
