Basic Knowledge About Cryptocurrency and Wallets

Before using iAutoPay, you need to understand some basic cryptocurrency concepts:

• Wallet Private Key: A key similar to a password, used to sign transactions. Keep it safe and never share it with anyone!
• Testnet: A network for testing where test coins can be obtained for free from faucets
• Mainnet: The official network that requires real funds
• USDC: A stablecoin pegged to US dollar (1 USDC ≈ 1 USD)

How to get test coins:

1. Visit the Base Sepolia faucet: https://sepoliafaucet.com/
2. Enter your wallet address
3. Get free test USDC

Security tips:

• Never share your private key
• Test thoroughly on testnet before using mainnet
• Use a dedicated wallet, don't store large amounts of funds
