Dam Fund Token
Implementing ERC-20 tokenusing open-zeplin
Libraries used
- node.js
- truffle
- openzeppeline-solidity
Getting started with truffle boxes
Follow below instructions to initialize new ethereum project from truffle boxes. We will use webpack template
mkdir DFToken`
cd DFToken
truffle unbox webpack
npm install openzeppelin-solidity@2.0.0
Versions compatibility
Update compiler version of solidity in `truffle-config.js`
Install compatible version of ethers `npm install ethers@4.0.20`
Cleanup unsed files
Delete files from contracts(except Migrations.sol) and test folders.
Create DFToken.sol in Remix
Create Smart Contract in Remix and make sure there is no compilation errors
Running the truffle
Start the truffle console
truffle develop
compile
migrate --reset
test
Running front end application
To start the front-end on http://localhost8080 in new terminal
rpm run dev
Front end application will be started. Now you can interact with your deployed Smart Contract from web application.
Integration with MetaMask
In order to perform transaction from front-end, you need to integrate your local blockchain with Metamask.
Go to your metamask plugin
Use option, Connect using “Custom RPC”, at address http://127.0.0.1:9545/
This is the port number, where the "truffle develop" runs the local network
Integration with Infura
If you want to interact with public ethereum networks e.g. (Mainnet, Testnet), you need to create Infura account
