Github Repo for Live Deployment 
Devfolio Project Write-Up 💻
This is a repo in which we have designed the smartcontract in solidity to work on the PaymentTrack Theme in DecentralHacks [Octaloops] Hackathon (20th Sept - 1st Oct).
Nowadays many business small or big has started accepting UPI Payments , in future as crypto starts to be more accepted we might see businesses & e-commerce websites start accepting Crypto as a form of payment on any purchase.
What we are thinking is that, we can write a smartcontract to take crypto payments equivalent to the listed price. Let's say if a product is listed for a certain amount in FIAT and the customer wants to pay in Crypto, as he goes to checkout , the latest-pricefeed of the selected cryptocurrency will be shown , Like if Listed Price is 300$ & the customer is paying using ETH Token & ETH/USD -> 3000$, he'll be shown the 0.1ETH + the Gas Fess as the Final Amount (we will be using Chainlink AggregatorV3Interface for getting the Pricefeeds), after which he can connect his Metamask & Pay.
We used Brownie (Python Development Framework for Ethereum) to deploy and test our smartcontracts on Ganache CLI, Testnets & Mainnet-Forks.
We designed out smartcontract in Solidity Language.
Account Factory smartcontract is for keeping a tract of all the accounts which are using the Payment Track and creating accounts & deploying smartcontract for payment which is written seperately in Account Demo Test smartcontract.
We are using Chainlink Oracle's AggregatorV3 Interface which has for fetching life price feeds from market for a particular CRYPTO/FIAT or a CRYPTO/CRYPTO pair.
Payment Function can be called by anyone over the network but the assets in the smartcontracts can only be withdrawn by the creator/owner of the smartcontract (i.e, who deployed it).
Deployment and all the functions were tested using Brownie on Ganache CLI & Rinkeby Testnet and are working properly.
