• Description: A web-based IDE for writing, testing, and deploying Solidity smart contracts.
• Key Features:
• Real-time Solidity compilation and error reporting.
• Integrated debugging tools and console.
• Supports testing and deploying contracts directly to Ethereum networks.

• Website: Remix IDE

• getSigners: Retrieves the list of accounts provided by the Ethereum node, with the first account used as the deployer.
• getContractFactory: Gets the contract to deploy.
• deploy: Deploys the contract with the specified parameters (name, symbol, and initial supply).
• parseUnits: Converts the initial supply to the correct units, considering the token’s decimals.

With the deployment script in place, you can now deploy your contract to a local blockchain or a testnet.
