The smart contract is written in Solidity, so it works on every blockchain network which can interpret the Solidity smart contracts. However in this demo application, we will use the Avalanche blockchain, so the network setup parts work for you only if you are using Avalanche as well.
Read more about the Avalanche blockchain here.

Make sure you have Go installed on your machine (>=1.16.8) and $GOPATH is set correctly.
$ go version$ echo $GOPATH -
Install Avalanche by running the following command:
$ yarn install:avalanche -
To start the local Avalanche node, run the following command:
$ yarn start:avalanche -
To fund the Avalanche node, you can use the endpoints declared in
http/fund.http. (can be used with REST Client vscode extension) - See docs for more info
For testing purposes we will use Hardhat.
-
intall the npm packages:
yarn -
fill out the
.envfile based on the.env.example -
run the tests:
yarn run test
We will use hardhat for our smart contract deployment. Be aware, the smart contracts on the network are immutable, you can't easily update them, but you can deploy a new one. In this case, the contract address changes and every asset stored on the original contract will stay in the original contract, you need to provide a solution for the migration. On the local and the test network it is not so important because the tokens are not real, so it is not necessarily causing any damage.
-
Start the local Avalanche network based on your network setup
-
Deploy the smart contracts to the local network:
yarn run deploy --network local -
Save the deployed address from the console and use it as an env variable in the front-end project (you need to update the address every time when you redeploy a smart contract)
