If you're here, you must have sent VET to your ETH address. Good news! If you own the private key to that ETH address, you're in luck. ETH addresses and VET addresses look the same, but the VET is not an ERC-20 token - that's how you were able to send VET to an ETH address. Right now, your VET is on an address that you technically own, as you own the private key to that corresponding ETH address. You need to derive your ETH address as a VET address by finding your private key and importing it into a VET wallet such as a Trust wallet. From there, you can send your VET wherever you'd like.
1. It would help if you considered using private keys and your 12 or 24-word phrases for your software/hardware wallet to be compromised. You will be entering them on a computer that is sometimes online. Before starting this process, move all of your assets from your software or hardware wallet to a secure location like a custodian or second hardware wallet. Once you have recovered your VET, you can make a new wallet to move everything back.
2. Download the latest release of bip39-standalone.html. This is a tool that will help you derive your ETH private key from your 12-word or 24-word phrase.
3. Download Trust Wallet for your smartphone to serve as an interim VET wallet.
4. For maximum security, unplug your computer from the Internet, or temporarily disconnect from WiFi. Open bip39-standalone.html, which you downloaded in Step 2, in a browser on its own. Now, type in your 12-word or 24-word phrase that you saved when creating your wallet where it says BIP39 Mnemonic and select ETH - Ethereum under the Coin dropdown. See here for an example:
5. Now it is time to find the private key that you need to import to your VET wallet. Scroll down on the BIP39 tool page to see the addresses derived from your 12-word phrase. The one at the top should be your ETH address. After checking your room for spies, click on the private key to the right of the address and public key to reveal the QR code of your private key.
6. With the QR code of your private key visible, open Trust Wallet for the first time. Tap on "I have a wallet," and then "VeChain." At the "Import VeChain" screen, you will see a tab on top that says "Private Key" - click on that and then click on the camera button at the top right of the app. Your camera will open. Scan the QR code of your private key and then tap "Import."
7. You will now see your VET balance in Trust wallet, but you're not done yet! Send your VET to a safe address - as I mentioned earlier, the 12-word/24-word phrase and the associated keys (so everything from your old wallet) should all be considered compromised. You can now make a new wallet with a new phrase and move your assets back onto your new wallet.
