convert wETH to EUROe (euro-pegged stablecoin) via cowswap & gnosis pay
About
SloppyTopUppy is a convient way to top up your gnosis pay balance by selling your eth and swapping it with cowswap. We use cowswap programmable orders in order to automattically sell when ever a users gnosis pay card wallet is below a certain balance. Cow swap will then automattically sell the users eth for EURe.
