IDE & Hands-on Practices

This guide explains how to deploy an EGC-20 token (ERC-20 equivalent for EGC ) using OpenZeppelin Wizard, Remix IDE, and MetaMask.

Step 1: Configure Your Token with OpenZeppelin Wizard

1

Configure token in OpenZeppelin Wizard

1. Open the OpenZeppelin ERC-20 Wizard: 👉 https://wizard.openzeppelin.com/#erc20

2. Enter your Token Name and Token Symbol.

   • Example: replace "MyToken" with your token name and "MTK" with your token symbol.

3. Set the Premint Amount.

   • Example: 1_000_000 for an initial supply of 1,000,000 tokens.

4. Click Open in Remix.

   • This will generate the smart contract code and open it directly in Remix IDE.

Step 2: Pre-requisites

Before deployment, ensure you have the following:

• MetaMask browser extension installed.

• MST Testnet network added in MetaMask.

  • Go to https://testnet.egcscan.com/, scroll to the bottom, and click Add EGC Testnet.

• tMSTC test funds in your wallet.

  • Request funds from the MST Faucet: https://faucet.egcscan.com/.

• First-time Remix IDE users will see an initial setup screen:

  • AI and Analytics Preferences: Select Accept

  • How you typically use Remix: Select Learning

Step 3: Understanding Remix IDE

Remix IDE is a browser-based development environment for writing, compiling, and deploying smart contracts. For EGC Blockchain developers, Remix acts as the bridge between contract code (Solidity) and the EGC Testnet (via MetaMask).

Key Features of Remix:

• File Explorer: Manage your Solidity smart contract files.

• Solidity Compiler: Compile contracts before deployment.

• Deploy & Run Transactions: Deploy contracts to the MST Blockchain using MetaMask.

• Debugger & Logs: Analyse contract execution and transaction results.

You do not need to install anything; Remix runs directly in your browser.

Step 4: Deploy Using Remix IDE

1

Connect Remix to MetaMask

1. Open the Deploy & Run Transactions tab in the left panel.

2. Open the Environment dropdown and select Injected Provider – MetaMask.

   • If not visible, click Customise this list, then under Deploy using a Browser Extension, enable Deploy through the MetaMask browser extension.

3. In MetaMask, select the EGC Testnet network. This should be reflected in Remix.

2

Compile and Deploy

1. Open the Solidity Compiler tab and click Compile Contract.

2. Return to Deploy & Run Transactions.

3. Click Deploy.

   • MetaMask will prompt for transaction confirmation. Approve it to deploy the contract on EGC Testnet.

3

Post-deployment

1. Once deployment succeeds, the contract will appear in Deployed Contracts at the bottom of Remix.

2. Copy the contract address from the deployed list for future interaction or verification.

Step 5: Verify Deployment

• Check the Deployed Contracts section in Remix.

• Alternatively, paste the contract address in MST Testnet Explorer: https://testnet.egcscan.com/ to view contract details.

Congratulations! You have successfully deployed your first EGC-20 token on the EGC Blockchain using Remix IDE.
