How To Restore Backup From LEAD Wallet (BETA) - old version
If you need to restore your wallet address from our old BETA app to our mainnet app, these are some steps that can help you:
The easiest way to solve this problem is to use your private keys from the old BETA app (not backup phrases) and restore them with the mainnet app. To do this, go to Settings. From there, find your list of wallets, and tap on Backup

Here you can see Reveal your Private Keys. Below that, there’s the text Reveal. Tap on Reveal. You will see various private keys within different networks. Let’s say your funds are stuck within some ERC-20 (Ethereum) or BEP-20 (Binance Smart Chain) tokens. To export your private keys elsewhere, just click the copy-paste button next to Ethereum Private Key.
After that, open our mainnet app, and swipe right in the main menu bar (on the bottom) and find Settings. Inside Settings, find Manage Wallet. Tap on Restore wallet using private key

Tap on Restore wallet using private key
You will see this page next:

Paste your private key from the old BETA app to the Enter private key row here
Here you can just use whatever name you want for your wallet. As for Select Coin, tap on Ethereum. And for Enter private key, paste the private key that you previously copied from the old BETA app.
Once you successfully restore your old wallet address to Lead mainnet app, just select this newly restored wallet as the Default under Manage Wallet. That’s it.
Alternatively, you can also restore the private key from the old BETA app to other crypto wallet applications. To do this, open a popular Ethereum wallet application and import the private key there (that you previously copy-pasted from the old BETA app). For example, let’s use Metamask. You can download Metamask from Google Play Store, App Store, or just use your desktop’s Metamask Chrome browser extension.
Above I explained how to restore the old wallets if you use Ethereum or BSC but you might be wondering what would you need to do if you need to transfer out your crypto funds outside Ethereum and BSC networks. In this case, use the same method as I explained above but you need to select different options under Select Coin. Copy the private keys from Lead Wallet (BETA) app and paste it to the mainnet app’s Restore wallet using private key.
