The following Tech tools where used in building this project
- Reactjs and Tailwindcss - To build and make the frontend and user interfaces
- Solidity - To write the smart contract deploy on ethereum chain
- IPFS Web3storage - To store transaction files
- Coinbase Wallet Sdk - Used to sign transactions in the dapp
- Worldcoin World Id - Used to verifiy a user create an account only once and they are unique humans
- Firebase - To store app data offchain

This is a short description of the architure and structure of our dapp.
Kryptpay works on two smart contracts :
*A Erc20 token smart contract - This contract implement the basic logic of native erc20 token ,KLV. It holds the logic for minting tokens to users
contract Link -https://github.com/Horlarmmy/KryptPay/blob/main/contracts/Token.sol
*A kryptPay App contract: this contract holds the logic on which the kryptpay dapp works on .It holds the functionalities for transfer,purchase,swap etc
contract Link- https://github.com/Horlarmmy/KryptPay/blob/main/contracts/KryptApp.sol
Transfer of tokens in kryptPay can be achieved simply if the email address recipient registered on our dapp is know.This reduce the risk of send tokens to the wrong walet address.
*Decentralized Exchange -allows the purchase and swap of tokens *Token transfer - to individuals and also utility providers
KryptPay offers a cheaper and easy payment gateway to allow for payment of basic utilities.
Utility providers such as water corps can simplyy integrate on KryptPay or registered on kryptpay .This will allow easy reception of payments from end users or customers all over the world.
##NOTE
We were able to fix the challange of importing custom erc20 token into coinbase wallet,it the following code snippet
ethereum.request({ method: "wallet_watchAsset", params: { type: "ERC20", options: { address: "0xE09Aa821C1480aE46364583563a500f1288f5E7D", symbol: "KLV", decimals: 18, image: "https://firebasestorage.googleapis.com/v0/b/kryptpay-f5b8a.appspot.com/o/mainlogo.png?alt=media&token=0ac99a8a-e9ba-4b80-ab69-16ff3af34f37", }, }, }) .then(response => { const result = result ? onApproveWatchAsset() : onDenyWatchAsset() }) .catch(err => onError(err.message));
