PLU is a token on the Ethereum network, so we definitely support it. You simply need to add it to Brave Wallet. Here’s how you do it on the CoinMarketCap page.
Just now before replying I closed Brave an reopened it.
Unlocked Brave’s built in wallet.
Went to CMC and clicked the metamask link.
Opened the wallet “deposit” page.
Searched “plu” - not there.
Refreshed page (F5) and searched again - not there.
My Win64 Brave is up to date.
The only extension I have is “Session Buddy”
