Development Tutorial
Introduction
Joltify provides a simple hardhat project for Solidity smart contract deployment and interaction on Joltify EVM co-chain.
Step 1: Configuration setup
To access the Joltify local chain and Joltify Testnet chain, configure the corresponding networks in joltevm/hardhat.config.js
as follows:
Alternatively, you can also set up accounts
with seed phrases as follows:
Step 2: Contract deployment
joltevm
directory contains an integrated Hardhat project for smart contract deployment and interaction.
A sample Solidity smart contract located at joltevm/contracts/token/Token.sol
can be easily deployed with:
Under the hood yarn token-deploy
is running cmd npx hardhat run --network testnet scripts/deploy/token.js
to deploy the token on Joltify testnet. You can also use the npx hardhat ...
syntax to interact with the contracts from the CLI.
Step 3: Contract interaction
Basic contract interaction is possible through additional scripts with the full list available in evm/package.json
. Each yarn cmd is aliased to one of the Hardhat tasks found in hardhat.config.js
.
You can get information about any cmd including param options by using the --help
flag, for example:
Using the available scripts, we can transfer tokens:
Step 4: Customised contract deployment
You can easily deploy your own contracts:
Add your Solidity smart contract to
joltevm/contracts
.Add a deployment script to
joltevm/scripts/deploy/[YOUR_SCRIPT].js
.Add Hardhat tasks corresponding to your contract's public methods to the existing tasks in
hardhat.config.js
.
Done! Now you can deploy and interact with your contract:
If you want a cleaner CLI experience, you can add some script aliases to joltevm/package.json
as seen in the scripts
section.
Step 5: Contract verification
To verify the deployed contract on joltify EVM explorer, you are required to set up etherscan
in hardhat.config.js
file as follows:
Once the configuration is set up, you can run the following command to verify the deployed contract on Joltify EVM explorer:
