@nv611520 Since you have transferred Ethereum over BSC Network, it won’t appear over Ethereum mainnet. You will have to add Binance Smart Chain (BSC) in Brave wallet to see your funds.
Like chh_68 said, you can add BSC in Brave wallet from https://chainlist.org/. Search for “BSC” there > connect your wallet > add the new network. Easy.
You can also manually add BSC here- brave://settings/wallet/networks. These are the fields you would need, link-
Mainnet
Network Name: Smart Chain
New RPC URL: https://bsc-dataseed.binance.org/
ChainID: 56
Symbol: BNB
Block Explorer URL: https://bscscan.com
In case if you wanted to participate in Swap-stakes, ETH over BSC won’t work as Swap in BSC is not available in release version yet. Recently it was pushed in Nightly, link.
Also to transact anything (moving funds etc.) over BSC you would need BSC’s native token which is BNB to pay gas fee.
