Project Description

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.

How it's Made

our project relies on 4 core partner technologies - CoW DAO, Gnosis, Blockscout, Fhenix.

Here's the info on how we utilized each partner's technology:

CoW DAO: convert wETH to EURe (euro-backed stablecoin), with the programmable orders

Gnosis pay: to spend the EURe coins in the real world

Blockscout:with foundry, we verify our EVM smart contracts on blockscout

Fhenix: we made an integer division library to do division with looped subtraction to avoid doing division OPCodes directly to save gas

NounsDAO: UI elements, fonts / colors, and overall messaging on the frontend

Other technologies we utilized are Figma (for designs), Ethereum as DB, html/css, js + node.js, solidity, & no JS frameworks on frontend. Some ETH Devtools we used include ethers.js, Foundry, OpenZeppelin SDK, & Remix.
