The platform is still quite new and I don't think it's working with with Meta Mask just yet. I haven't kept up with any updates. That's why I did it with Keystore. I'll try with Meta Mask in the near future and I'll make a tutorial with that once it's working properly.
I tried it again using the keystore, now I got 20 ARB from my 60 LEO. But when I try to do a HIVE to BTC swap I still get this message.
"You need Arbitrum ETH to do this swap. Your current balance is $0.00. Please send Arbitrum ETH to your wallet or click "Arbitrum Gas Faucet" above to instantly get $5 worth of gas."
So after I got the ARB I swapped it for ETH with an ARB symbol in the corner and seems that is the "ArbETH"
Think it worked, gonna try to swap again.
