I've been trying to create an Ethereum Transaction but keep getting the 320000 invalid sender error. From other questions I've seen, this may be caused by errors in signing, sender address or chainID, yet after working with these I still get an error. I'm not supplying any code because I'm not looking for someone to fix my code, but rather wondering if there is any code/documentation I can look at provided by Ethereum for exactly this error. Thanks!
Edit: I have found https://github.com/ethereum/go-ethereum/blob/86e77900c53ebce3309099a39cbca38eb4d62fdf/core/tx_pool.go , does this work?
