Vires.Finance works with waves, you will need a waves wallet (for example waves.keeper) and waves.exchange, and of course a deposit on waves exchange (waves or USDN for example).
Once you are connected on vires.finance (through waves.keeper), borrow USDN
go to waves.exchange and buy USDC with the borrowed USDN
Once you bought your USDC, simply click on supply on vires.finance
That's it !! sit calm and enjoy your profit
