I am building out XEM payment integrations using a python tech stack and trying to find the most efficient way to accomplish this. I would also like to sign the transaction offline, so that I can broadcast the signed transaction to a supernode so that I don’t have to build out separate node infrastructure for my use case (if possible).
Alternatively, is the recommended way to sign/send a transaction is by using the
/transaction/announce endpoints? And since you’re posting your private key, then you’d only do this when you’re running your own local node?
