🚀 Quick Start
Choose your preferred implementation:
- React and NextJS with Hardhat or Foundry
- Vue and NuxtJS with Hardhat or Foundry
📦 Installation
Open up your terminal (or command prompt) and type the following command:
npx create-edu-dapp <your-dapp-name>
# Select Hardhat or Foundry Option
# cd into the directory
cd <your-dapp-name>
Note: If you have used the npx command then you don't have to install manually in any directory.
Hardhat Setup
📜 Smart Contracts
All smart contracts are located inside the backend
aka hardhat
folder, which can be found in the root directory. To get started, first install the necessary dependencies by running:
# change directory into the backend folder
cd backend
npm install
🔑 Private Key
Ensure you create a .env
file in the backend
directory. Then paste your Metamask private key in .env
with the variable name ACCOUNT_PRIVATE_KEY
as follows:
ACCOUNT_PRIVATE_KEY=0x734...
⚙️ Compile
Now, you can write your contracts in ./contracts/
directory, replace Greeter.sol
with <your-contracts>.sol
file.
# For compiling the smart contracts
npx hardhat compile
After successful compilation, the artifacts directory will be created in ./src
with a JSON /contracts/<your-contracts>.sol/<your-contracts>.json
containing ABI and Bytecode of your compiled smart contracts.
🧪 Test
To write tests, go to ./test
directory and create <your-contracts>.ts
, you can test your smart contracts using the following command.
# For testing the smart contracts
npx hardhat test
⛓️ Deploy
Before deploying the smart contracts, ensure that you have added the Open Campus Codex
to your MetaMask wallet and that it has sufficient funds. If you do not have testnet $EDU on Open Campus Codex, please follow this faucets guide.
Also, make changes in ./scripts/deploy.ts
(replace the greeter contract name with <your-contract-name>
).
For deploying the smart contracts to open campus codex
network, type the following command:
# For deploying the smart contracts
npx hardhat run scripts/deploy.ts --network opencampus
<your-contract> deployed to: 0x...
Copy and paste the generated contract JSON ABI folder contracts
inside the backend/src/contracts
directory to the /frontend/
directory.
Copy and paste the deployed contract address in the frontend page directory. For example, if the deployed contract is Greeter.sol
, then you have to paste the address in frontend/app/(dapps)/simple-greeting-dapp/page.tsx
.
✅ Verify
To verify the deployed smart contract on Open Campus Codex
, execute the following command:
# For verifying the smart contracts
npx hardhat verify --network opencampus <deployed-contract-address>
Foundry Setup
📜 Smart Contracts
All smart contracts are located inside the backend
aka foundry
folder, which can be found in the root directory.
# change directory into the backend folder
cd backend
🔑 Private Key
Ensure you create a .env
file in the backend
directory. Then paste your Metamask private key in .env
with the variable name ACCOUNT_PRIVATE_KEY
as follows:
ACCOUNT_PRIVATE_KEY=0x734...
⚙️ Compile
Now, you can write your contracts in ./src/
directory, replace Greeter.sol
with <your-contracts>.sol
file.
# For compiling the smart contracts
forge compile
After successful compilation, the artifacts directory will be created in ./out
with a JSON /<your-contract>/<your-contracts>.json
containing ABI and Bytecode of your compiled smart contracts.
🧪 Test
To write tests, go to ./test
directory and create <your-contracts>.t.sol
, you can test your smart contracts using the following command.
# For testing the smart contracts
forge test
⛓️ Deploy
Before deploying the smart contracts, ensure that you have added the Open Campus Codex
to your MetaMask wallet and that it has sufficient funds. If you do not have testnet $EDU on Open Campus Codex, please follow this faucets guide.
Also, make changes in ./script/DeployGreeter.s.sol
(replace the deploy greeter contract name with <your-contract-name>
).
For deploying the smart contracts to open campus codex
network, type the following command:
# For deploying the smart contracts
forge script script/DeployGreeter.s.sol --broadcast --rpc-url https://rpc.open-campus-codex.gelato.digital/ --gas-limit 30000000 --with-gas-price 5gwei --skip-simulation
<your-contract> deployed to: 0x...
Copy and paste the generated contract JSON ABI folder Greeter.sol
inside the backend/out/
directory to the /frontend/contracts/
directory.
Copy and paste the deployed contract address in the frontend page directory. For example, if the deployed contract is Greeter.sol
, then you have to paste the address in frontend/app/(dapps)/simple-greeting-dapp/page.tsx
.
✅ Verify
To verify the deployed smart contract on Open Campus Codex
, execute the following command:
# For verifying the smart contracts
forge verify-contract \
--rpc-url https://rpc.open-campus-codex.gelato.digital \
--verifier blockscout \
--verifier-url 'https://opencampus-codex.blockscout.com/api/' \
<deployed-contract-address> \
[contractFile]:[contractName]
Next.js Client
Start the Next.js app by running the following command in the frontend
directory:
# Change directory into the frontend folder
cd frontend
# Start the development server
npm run dev
