Deployment to a testnet or mainnet

• You'll want to set your SEPOLIA_RPC_URL in environment variables. You can add them to a .env file, similar to what you see in .env.example.

2. Use wallet options to Encrypt Private Keys

• Private Key Encryption

Optionally, add your ETHERSCAN_API_KEY if you want to verify your contract on Etherscan.
