I have an Ethereum paper wallet with the private key. I want to only spend a fraction of the ethereum on this private key. I also have a few USDC tokens on it that I want to also spend.
- How can I spend only a portion of it? Which "command line" wallet supports this?
I'm trying to create an online service where I can put in my private key and spend fractions of my ethereum, but not sweep all the funds to a new address. My main concern is doing this via the command line. Which is the best wallet / tool to process private keys to spend partial amounts using only the command line?
