Make sure you did export the private key instead of importing the seed phrases. And Have you tried to import the private keys to other wallets?
Which Wallets support VET? I tried Comet Wallet (https://cometpowered.com), but this site ain't work (I can't create a wallet). It's not available in the Chrome Web Store anymore.......
By importing a wallet via the VechainThor app I took the following steps:
Import a wallet > Mnemonic Phrases > filled in the recovery phrases > Gave the wallet a name. Now I think this ain't the right thing?
The Metamask Community shows me a Comet solution, which ain't work as mentioned above.
If I only had a person right next to me, who can step by step help me solving this irritating problem.......
There you go. I already suspect that you are importing Metamask seed phrase instead of the address private key.
Ideally, if you are using the same seed phrase, you should be able to get that particular address by just creating a new address on your VechainThor APP, try to add a new address like 5 or 6, then see if the ....adda address shows up.
But in case the above method doesn't works, another thing you can try is:
1. Export the private key of 0x1bacb2431d48634464c1a6fe7961397720c7adda address on the Metamask. Refer to and adhere to the warning on https://metamask.zendesk.com/hc/en-us/articles/360015289632-How-to-Export-an-Account-Private-Key
2. Import the private key into the wallet.
You should've get the adda address on the wallet, but I don't know if the wallet support manually importing via private key, so you should try it.
Note that, importing seed phrases from some wallet to another wallet is not a good security practice. Also, since you are dealing with sensitive information, make sure you are doing in a secure environment.
