The mobile dApp will have the following feature:\n\n+ Issue Certificate - The authorized person will be able to issue the certificate\n+ Verify Certificate - Anyone can check the authenticity of the certificate and verify whether it was issued by the college\n+ View Certificate Details - the individual can access their certificate details from the system\n+ View Account Information - User will be able to see account address and its balance\n\n# Replicate the above mobile dApp\nIn oder to try this app, follow the steps given below\n\n## Clone tbe app and install the necessary packages\n```\ngit clone git@github.com:sumukus/gcitCert.git gcitCert\ncd gcitCert\nnpm i\n\n```\n### Edit the file inside smartcontract directory\nYou have to edit the gcitCert.sol file.\n+ Inside the gcitCert.sol file replace the address in addgcitCert method with one of your MetaMask wallet account address from testnet(Sepolia)\n\n```\nrequire(msg.sender == address(0x9dC22219076ef89d9E0a6248F18B3582Ea7A93dB), \"Only the authorized issuer can add certificates\");\n```\n\nThen deploy the smart contract in the Sepolia testnet and take note of the contract address. We will require it later on to interact \nwith the smart contract. \n\n## Create .env file \nCreate the .env file in the root directory and add the details for the given fields \n```\nSMART_CONTRACT_ADDRESS=Your smart contract address \nINFURA_API=infura api for your app\nCERTIFICATE_ISSUER=address of certificate issuer\n```\n## Run the dApp\nNow you can run the dApp using the command given below\n```\nnpx expo start\n```\n\u003cimg src=\"https://github.com/sumukus/gcitCert/blob/main/login.png\" \n        alt=\"Radio Buttons Image\"  \n        height=\"100%\"\n        width=\"200\"/\u003e\n  \n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsumukus%2Fgcitcert","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsumukus%2Fgcitcert","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsumukus%2Fgcitcert/lists"}
