In the section 'Launch > IPO stakeholders' (on the Heavycoin web site) there is the following instruction:
"Procedure 2 investors should examine their records very careuflly and double check that their stakes and Heavycoin addresses are correct. You must report any mistakes to the Heavycoin developers before March 6th 00:00 UTC. Failure to do so could result in the loss of your IPO funds."
Now, how are we supposed to check the assigned Heavycoin addresses (as this is not something we generated)?
With the keygen tool you got a privatekey, a public key and an address. So yes, you can check it.
When I run genkeys.exe I can only generate a new address. How can I use it to check an existing address?
As explained in the IPO instructions, you should have saved your keypair. This is what you need to confirm your public key and that you have the corresponding private key.
4. Save your Heavycoin Private Key, Public Key and Address in a very safe place.
If you have lost them, then you will need to generate a new keypair and send us the new public key and list of your IPO investment transactions. We would then update the official IPO stakeholder list and you can confirm again.
