How to access migrated Aeternity?

Some time ago, I had migrated my ERC Aeternity tokens to the following address:


Now, when I check the address with the AEknow explorer I see my expected 5878.7998 AE coins. Further, the verification tool at also confirms each of my migrations steps I had performed when I paste the corresponding payloads from the ETH TX.

However, it seems that during the migration I seem to have received only the AE address, but in the migration document there is no AE private key (or mnemonic phrase) whatsoever. However, I still have access to the original Ethereum address’ private key. How do I now import my native AE coins into an Aeternity wallet?

I tried using the original Ethereum address’ private key e.g. with the “Base aepp” without much luck. I guess/hope there is some tool to convert my ETH private key into a form that would correspond to the mnemonic of my Aeternity address?

During the migration process you specified the public key yourself, so you will have to also have the private key wherever you got that public key from.


All I have is this piece of PDF below, which I had kept during the migration. I don’t remember of providing the AE address myself, but it was (as far as I recall) autogenerated. Hence, I don’t have a corresponding private key (seed phrase) of the AE address, but only the the original ETH address.

It was somehow my understanding, that I would be able to “derive” the AE private key later by the original ETH private key. Are you saying that my AE are now lost? I’ve looked everywhere but I really don’t seem to have stored the AE private key anywhere; which would be not like me at all. I’m very diligent when it comes to handling my private keys… :exploding_head:

I found it: apparently I had used my Ledger with the Base aepp wallet! Hence the reason why there was no seed phrase. Man this was close… wasted my entire weekend until I figured this. :hot_face:
