Just a random bloke on the internet but I’ll try to help. Could you try removing the fantom network from Brave and then re-adding it from chainlist.org ? If that doesn’t work maybe you can also restore your wallet on another web3 wallet like Metamask or Rabby just to see if you can view your funds from there and make sure that Brave Wallet is the problem.
The Fantom Network on the wallet works. Otherwise, i wouldn’t have been able to bridge my FTM on the Eth network to fantom network through spiritswap in the first place.
I did consider restoring my brave wallet on Metamask using Google Chrome instead of the Brave browser.
The problem is that I don’t know how to access my private key or json file on my Brave wallet, which is required to import my wallet over to Metamask.
Oh, if you go on “Accounts” you should see a “back up now” option next to your primary wallet. Selecting that will take you to your 12-word seed phrase.
