The function emitNewEvent wil emit an event with the following properties:

event EventDOMEv1(
  uint256 indexed index,  
  uint256 indexed timestamp,  
  address indexed origin,

Deployment

Project installation

Prerequisites: NodeJS (tested with v18.17.0)

npm install

Localhost with Alastria network's state fork

You can interact with Smart Contracts in localhost network which contains all the Alastria T Network state. With this project, you can get a complete fork of the original network in localhost, thanks to hardhat network configuration in hardhat.config.ts file.

npx hardhat clean
npx hardhat compile
npx hardhat run ./scripts/deploy.ts --network hardhat

Alastria Mainnet

.env file must be filled with the private key, and the IP of the network's node.

Deployment in T Network

npx hardhat clean
npx hardhat compile
npx hardhat run ./scripts/deploy.ts --network t_alastria

Deployment in B Network

npx hardhat clean
npx hardhat compile
npx hardhat run ./scripts/deploy.ts --network b_alastria

Automated testing

You can run the automated tests with the following command:

npx hardhat test

Coverage

1. ✓ Deployment should assign the deployer's address to the allowed address
2. ✓ Allowed address should be able to emit an event
3. ✓ NOT Allowed address should NOT be able to emit an event
