Thank you. I'm looking forward to your answer

Answer 1

So... there is actually no official mechanism right now for getting the address which corresponds to the imported private key. Part of the reason is that you should generally already have that address (from wherever you generated/copied the private key) but perhaps that doesn't apply in your situation.

We'll look into adding something to help with this. In the meantime, if the private key is not already in the wallet, it will be added as the last key in the wallet. So after importprivkey you can retrieve the address using:

listaddresses * false 1

If I have that address, can I get the address with my private key?

Can you please explain the question again?

how to calculate from private key to address
give me solution plz

You can look up the bitcoin documentation for this, bearing in mind MultiChain's different method for versioning private keys and addresses:

Or you can wait for the release of 1.0.2 which we hope will include a solution inside MultiChain itself.

Answer 2

MultiChain 1.0.2, just released, lets you pass a private key to validateaddress instead of an address, and the response will include address corresponding to that private key. Thanks again for bringing this issue to our attention.
