Deploy and Mint ERC-20 Tokens on Swisstronik: A Step-by-Step Guide
This guide will walk you through the entire process of deploying and minting ERC-20 tokens on the Swisstronik blockchain using Hardhat and OpenZeppelin Contracts Wizard. By following these detailed steps, you’ll be able to create your own token, deploy it on the Swisstronik blockchain, and transfer tokens. Let's get started!

Step 1: Creating a New Hardhat Project
The first step is to set up your development environment using Hardhat, a tool designed for building and testing smart contracts on Ethereum-compatible blockchains like Swisstronik.
Start by creating a new directory on your local machine for the project.
Next, install Hardhat in your directory using your preferred package manager (such as npm or yarn).
Once installed, initialize Hardhat in the directory by running the initialization command. This sets up the project and provides a basic configuration that will allow you to develop and test smart contracts.

Step 3: Creating an ERC-20 Smart Contract
The next step is to create your ERC-20 token using OpenZeppelin Contracts Wizard, which simplifies the process of building secure smart contracts.
- Use the OpenZeppelin Wizard to create an ERC-20 smart contract. The tool allows you to customize the contract, adding features like minting and burning tokens.
- Once the contract is generated, copy the code and add it to your Hardhat project.
- Now, compile the contract using Hardhat. This ensures the code is error-free and ready for deployment. Compilation transforms your Solidity code into bytecode that can be executed on the blockchain.

Step 4: Deploying the Smart Contract
With your ERC-20 contract created and compiled, it's time to deploy it to the Swisstronik blockchain.
- Create a deployment script within your Hardhat project. This script will define how the contract will be deployed to the network.
- Once the script is ready, run the deployment command in your terminal. Hardhat will use your configuration and private key to deploy the contract to the Swisstronik blockchain.
- After deployment, you’ll receive a contract address and a transaction hash. This contract address is where your ERC-20 tokens will live on the blockchain.

Step 5 & 6: Minting and Verifying the Contract
The final steps involve minting tokens and verifying the contract deployment.
- Create a script to mint 100 ERC-20 tokens using the deployed contract. You can also create a script to transfer tokens between addresses to test the functionality of your contract.
- After minting, verify the transaction by checking the contract address on the Swisstronik Blockchain Explorer. This allows you to see the transaction history and confirm the minting of your tokens.
By completing these steps, you’ve successfully deployed an ERC-20 token on the Swisstronik blockchain and minted tokens. You now have your own functional smart contract live on a decentralized blockchain.

Step 2: Configuring Hardhat for the Swisstronik Blockchain
Now that Hardhat is set up, you need to configure it to connect with the Swisstronik blockchain.
Open the hardhat.config.js file and add the necessary Swisstronik network information. This will allow Hardhat to communicate with the blockchain during deployment.
Add your private key in the configuration file. This key will be used to sign transactions when deploying your smart contracts. Make sure to handle the key securely, as it will control access to your account on the Swisstronik network.
