And we implemented the Alchemy for virtualization purposes. Finally we used ropsten for local testing and deployed on ropsten using hardhat** 5 | 6 | **Project Link** - ***https://alanbinu-crypto.web.app/*** 7 | 8 | ## Tech We Used 9 | 10 | - ReactJs 11 | - Firebase Hosting 12 | - Firebase Auth 13 | - Solidity 14 | - Alchemy 15 | - Ropsten 16 | - Hardhat 17 | - Ropsten Etherscan 18 | 19 | ## Features 20 | 21 | - Send Etherium 22 | - Can able to view all the transacations 23 | 24 | ## Steps to run in your machine 25 | 26 | You need to install MetaMask in your browser : https://chrome.google.com/webstore/detail/metamask/nkbihfbeogaeaoehlefnkodbefgpgknn?hl=en and creeate one account. 27 | 28 | Create on account in Alchemy (for virtualization purposes) : https://dashboard.alchemyapi.io/ and create one app 29 | 30 | 31 | #### Run the following commands 32 | ``` 33 | clone this repo 34 | ``` 35 | Go to both folders and run thew following command 36 | 37 | ``` 38 | npm install 39 | ``` 40 | Go to Alchemy and copy thr HTTP ID of the app that we created --> and paste it in smart_contract/hardhat.config.js 41 | ``` 42 | url : "" 43 | ``` 44 | 45 | Then go to MetaMask and copy the Eth account PRIVATE ID under Account Details and paste it in smart_contract/hardhat.config.js 46 | ``` 47 | accounts :["PRIVATE KEY"] 48 | ``` 49 | 50 | Then run the following command in smart_contract root folder 51 | 52 | ``` 53 | npx hardhat run scripts/deploy.js --network ropsten 54 | ``` 55 | 56 | The you can see that some compiled files are generated and also one DEPLOYED ADDRESS copy that address --> go to client/src/utils/constants.js 57 | ``` 58 | export const contractAddress = "" 59 | ``` 60 | 61 | Then go to smart_contract/artifact/contracts/Transactions/ and copy the Transacation.json (which contains all our contract details in json form) ---> and paste it into client/src/utils/ 62 | 63 | ## NOTE:
    64 | 65 | Inoder to run this application it required some gas (some kind of fee), so your must need some Eth

    66 | For testing purposes, here comes ROPSTEN. It provide free Eth for testing purposes.
    67 | To claim free test Eth go to your MetaMask -> Network Settings -> Turn ON test network and connect to "Ropsten test network".

    68 | Then copy your account address and go to : https://faucet.egorfine.com/ and paste your address and claim free test Eth of 0.300 Eth.
