This is looking quite tragic for me :frowning: Any reason why this happened?

I sent 10 ZEC, that was received by the other account, however 56.7 ZEC was sent to an account I did not specify.

As it turns out the remainer was deposited in a “change” account that was automatically created on my local wallet. Not great that it was not obvious, but I am glad the amount was not lost.

Good good !

Always remember to back-up your wallet and also make a back-up of the private key for the change addresses !
