DEPLOY SMART CONTRACT ON VALIDIUM NETWORK:

This project provides a Hardhat-based environment for deploying and interacting with smart contracts on the Validium network.

Setup

  1. Environment Variables: Add the following to your .env file:

    WALLET_PRIVATE_KEY=YOUR_PRIVATE_KEY
INFURA_API_KEY=YOUR_INFURA_API_KEY

  2. Install Dependencies: Install the project dependencies:

    npm install

Usage

1. Compile Contracts

Compile all contracts inside the contracts folder:

npm run compile

2. Deploy Contract

Deploy a contract using the deploy.ts script:

npm run deploy

The script will first check for compiled contracts in the artifacts-zk/contracts directory. If no compiled contracts are found, it will prompt you to compile them.

If compiled contracts are found, the script will then prompt you to enter the following information:

  • Select a compiled contract to deploy: A list of compiled contracts will be presented for you to choose from.
  • Constructor arguments: A comma-separated list of arguments for the contract's constructor (if any).

3. Interact with Contract

Interact with a deployed contract using the interact.ts script:

npm run interact

The script will first check for compiled contracts in the artifacts-zk/contracts directory. If no compiled contracts are found, it will prompt you to compile them.

If compiled contracts are found, the script will then prompt you to enter the following information:

  • Select a compiled contract to interact with: A list of compiled contracts will be presented for you to choose from.
  • Deployed contract address: The address of the deployed contract you want to interact with.

After selecting the contract and providing its address, the script will enter an interactive loop. In each iteration, it will prompt you to select an action:

  • Call a function (state-changing): This will present a list of all state-changing functions available in the selected contract. If the chosen function requires arguments, you will be prompted to enter them as a comma-separated list. The transaction hash will be displayed, and the script will wait for the transaction to be mined.
  • Call a view/pure function (read-only): This will present a list of all view and pure functions available in the selected contract. If the chosen function requires arguments, you will be prompted to enter them as a comma-separated list. The return value of the function will be displayed.
  • Exit: This will terminate the interaction script.
