2 | 3 | 4 | ## Dex-aggregator 5 | 6 | With the ever growing DEFI world and the appearance of multiple decentralized exchanges on the different blockchains, the WEB3 ecosystem needs a way to compare the pros & cons of swapping on each DEX. 7 | 8 | This excatly what Paraswap & 1inch protocol are trying to do, they aggregate the prices of tokens from multiple exchanges in each Blockchain (for example: uniswap, sushiswap, shibaswap in the Ethereum Mainnet), then they compare those prices and the swapping fee and offer to their user the best exchange rate possible. 9 | 10 | In this Dapp, i built a simplified version of Paraswap it works on 4 blockchains: Ethereum, Polygon, Binance Smart Chain and the kovan testnet.For the moment it supports some well known tokens (ETH, Matic, Dai, USDC,...). 11 | 12 |

15 | 16 | ### Built With 17 | 18 | * [Solidity](https://docs.soliditylang.org/) 19 | * [Brownie](https://eth-brownie.readthedocs.io) 20 | * [React.js](https://reactjs.org/) 21 | * [ethers.js](https://docs.ethers.io/v5/) 22 | * [web3modal](https://github.com/Web3Modal/web3modal) 23 | * [material ui](https://mui.com/getting-started/installation/) 24 | 25 | 26 | 27 | ## Getting Started 28 | 29 | ### Prerequisites 30 | 31 | Please install or have installed the following: 32 | * [nodejs and npm](https://nodejs.org/en/download/) 33 | * [python](https://www.python.org/downloads/) 34 | * [MetaMask](https://chrome.google.com/webstore/detail/metamask/nkbihfbeogaeaoehlefnkodbefgpgknn) Chrome extension installed in your browser 35 | 36 | ### Installation 37 | 38 | 1. Installing Brownie: Brownie is a python framework for smart contracts development,testing and deployments. It's quit like [HardHat](https://hardhat.org) but it uses python for writing test and deployements scripts instead of javascript. 39 | Here is a simple way to install brownie. 40 | ``` 41 | pip install --user pipx 42 | pipx ensurepath 43 | # restart your terminal 44 | pipx install eth-brownie 45 | ``` 46 | Or if you can't get pipx to work, via pip (it's recommended to use pipx) 47 | ```sh 48 | pip install eth-brownie 49 | ``` 50 | Install [ganache-cli](https://www.npmjs.com/package/ganache-cli): 51 | ```sh 52 | npm install -g ganache-cli 53 | ``` 54 | 2. Clone the repo: 55 | ```sh 56 | git clone https://github.com/kaymen99/Dex-aggregator.git 57 | cd Dex-aggregator 58 | ``` 59 | 60 | 3. Set your environment variables 61 | To be able to deploy to real testnets you need to add your PRIVATE_KEY (You can find your PRIVATE_KEY from your ethereum wallet like metamask) and the infura project Id (just create an infura account it's free) to the .env file: 62 | ``` 63 | PRIVATE_KEY= 64 | WEB3_INFURA_PROJECT_ID=<< YOUR INFURA PROJECT ID >> 65 | ``` 66 | You can choose to use ethereum testnets like rinkeby, Kovan or any other evm compatible testnet. 67 | You'll also need some eth in the testnet. You can get it into your wallet by using a public faucet. 68 | 69 | 70 |

Once you `eject`, you can't go back!** 35 | 36 | If you aren't satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project. 37 | 38 | Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own. 39 | 40 | You don't have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it. 41 | 42 | ## Learn More 43 | 44 | You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started). 45 | 46 | To learn React, check out the [React documentation](https://reactjs.org/). 47 | 48 | ### Code Splitting 49 | 50 | This section has moved here: [https://facebook.github.io/create-react-app/docs/code-splitting](https://facebook.github.io/create-react-app/docs/code-splitting) 51 | 52 | ### Analyzing the Bundle Size 53 | 54 | This section has moved here: [https://facebook.github.io/create-react-app/docs/analyzing-the-bundle-size](https://facebook.github.io/create-react-app/docs/analyzing-the-bundle-size) 55 | 56 | ### Making a Progressive Web App 57 | 58 | This section has moved here: [https://facebook.github.io/create-react-app/docs/making-a-progressive-web-app](https://facebook.github.io/create-react-app/docs/making-a-progressive-web-app) 59 | 60 | ### Advanced Configuration 61 | 62 | This section has moved here: [https://facebook.github.io/create-react-app/docs/advanced-configuration](https://facebook.github.io/create-react-app/docs/advanced-configuration) 63 | 64 | ### Deployment 65 | 66 | This section has moved here: [https://facebook.github.io/create-react-app/docs/deployment](https://facebook.github.io/create-react-app/docs/deployment) 67 | 68 | ### `npm run build` fails to minify 69 | 70 | This section has moved here: [https://facebook.github.io/create-react-app/docs/troubleshooting#npm-run-build-fails-to-minify](https://facebook.github.io/create-react-app/docs/troubleshooting#npm-run-build-fails-to-minify) 71 | -------------------------------------------------------------------------------- /front-end/package.json: -------------------------------------------------------------------------------- 1 | { 2 | "name": "front-end", 3 | "version": "0.1.0", 4 | "private": true, 5 | "dependencies": { 6 | "@emotion/react": "^11.9.0", 7 | "@emotion/styled": "^11.8.1", 8 | "@mui/material": "^5.6.0", 9 | "@reduxjs/toolkit": "^1.8.1", 10 | "@testing-library/jest-dom": "^5.16.4", 11 | "@testing-library/react": "^12.1.4", 12 | "@testing-library/user-event": "^13.5.0", 13 | "bootstrap": "^5.1.3", 14 | "ethers": "^5.6.2", 15 | "framer-motion": "^6.2.9", 16 | "moment": "^2.29.3", 17 | "react": "^18.0.0", 18 | "react-bootstrap": "^2.2.3", 19 | "react-dom": "^18.0.0", 20 | "react-redux": "^7.2.8", 21 | "react-scripts": "5.0.0", 22 | "redux": "^4.1.2", 23 | "redux-persist": "^6.0.0", 24 | "styled-components": "^5.3.5", 25 | "web-vitals": "^2.1.4", 26 | "web3modal": "^1.9.6" 27 | }, 28 | "scripts": { 29 | "start": "react-scripts start", 30 | "build": "react-scripts build", 31 | "test": "react-scripts test", 32 | "eject": "react-scripts eject" 33 | }, 34 | "eslintConfig": { 35 | "extends": [ 36 | "react-app", 37 | "react-app/jest" 38 | ] 39 | }, 40 | "browserslist": { 41 | "production": [ 42 | ">0.2%", 43 | "not dead", 44 | "not op_mini all" 45 | ], 46 | "development": [ 47 | "last 1 chrome version", 48 | "last 1 firefox version", 49 | "last 1 safari version" 50 | ] 51 | } 52 | } 53 | -------------------------------------------------------------------------------- /front-end/public/favicon.ico: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/kaymen99/Dex-aggregator/f9f1478ec780196f5b4248535bccbf05b513fcc3/front-end/public/favicon.ico -------------------------------------------------------------------------------- /front-end/public/index.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 12 | 13 | 17 | 18 | 27 | React App 28 | 29 | 30 | 31 |
