JahirulIslam Exporting your private key has caused Fortmatic to create a new wallet with a new private key and since this new wallet no longer matches the one you used to redeem the Airdrop, you can no longer log in to your trading account.
These are the corresponding sections of the Fortmatic User Terms of Service:
Please note, if you choose to export your private key to your Wallet, you will be unable to use that Wallet in connection with Fortmatic’s Services and you will not be able to access that Wallet using an account created with Fortmatic.
If you would like to stop using the Services and export the contents of your Wallet, you may choose to export a copy of your private key from your account. Upon electing to export your private key, Fortmatic will generate a downloadable file of your private key encrypted with a password of your choosing (the “Private Key File”). Once Fortmatic has provided you access to your Private Key File:
- You will no longer have access to the Virtual Currency of the exported Wallet or private key through Fortmatic.
- You will not be able to re-import your Private Key File to your Fortmatic account.
- A new Wallet or new private key will be generated for your Fortmatic account, so you may still use your Fortmatic account if you would like to use the Services again.
As it seems that you have successfully exported your private key, the only chance to recover your original wallet is to find the exported Private Key File (a JSON file) and import it into Metamask.
