Users will be able to move the WAVES token between the two blockchains through a gateway launched in the Waves.Exchange client interface. The withdrawal fee will be 2 WAVES and the deposit fee will be 0 WAVES. In order to issue one ERC20 WAVES, users have to lock one WAVES on the Waves blockchain.
wow 2 waves , thats expensive escpecially when waves goes much higher ( still hoping

), and honestly i dont know why i want to send / convert my waves to a erc-20 token, maybe it will make more sense in the future
