Running locally

This article goes through the ganache metamask setup: https://asifwaquar.com/connect-metamask-to-localhost/

Ganache

The truffle configuration file current deploys the contracts to Ganache running on 127.0.0.1 on port 7545

Connecting metamask

• Add a new network on metamask: RPC url will be whatever you are running on Ganche, default is: http://127.0.0.1:7545, chainId is 1337 for Ganache
• Once connected to Ganache, import some accounts to metamask using the private keys in Ganache

Deploying Contracts and connect contract

To connect a deployed contract:

Get the contract address from the truffle migrate output and paste it into the App.js file on line 16~ for the variable contractAddr.

To interact with smart contracts through the frontend after making a change to the smart contracts, generally you will need to run:

truffle migrate --reset

This clears the previous contract deployment and will deploy it to another address.
