Sending RBTC from metamask

im having an issue sending RBTC from my metamask to my liquidity wallet,
the balance is 0.001 RBTC ($57), when i try and send it shows an error insufficient funds,
to the point where i try and send even 0.000001 RBTC ($0.05) it shows an error insufficient funds

darren05 What is RBTC? :smile: RealBitcoin? use Binance Smart Chain?
Binance Smart Chain use gas BNB (Binance Coin)
and Ethereum transaction use ETH

@Luigi It’s rootstock RSK bitcoin, using the RSK mainnet on metamask, I know the difference in BNB and ETH just I’m not sure or can’t find info on the RSK fees and whatnot

oh sorry man :smile: I don’t use RSK Mainnet

This is RSK explorer :face_with_monocle: and I see fee: 0.000001368444 RBTC and Gas: 21,000
