How to verify a private key without making a transaction ?

[xtyling]

So I have created a new wallet but I dont have ETH to send/verify if the private key is working.

I have done the following steps to verify the private key is working as expected,
1. Created a sign message and verified it (Message verified successfully)
2. Used my private key to get the public address on myetherwallet

Are those 2 options enough to assume that the private key will work when I do a transaction ?

Anyone can confirm ? Thanks
