Solidity, Blockchain, and Smart Contract Course with Python Tutorial
I learnt about:
- MetaMask Added
- Account Created
- Mnemonic Keys : All of your account can access. (Keep Private)
- Public Key : No account access.
- Private Key : Only one account can access.(Keep Private)
- Etherscan
- TestNet : TestNets are free and for testing smart contract.
- MainNet : MainNet cost money and are considered as live.

What have Smart Contracts done so far?
Making Your First Transaction
- Metamask Download Link
- Etherscan
- Goerli Etherscan
- Goerli Faucet (Check the link token contracts page)
- NOTE: The Chainlink documentation always has the most up to date faucets on their link token contracts page. If the faucet above is broken, check the chainlink documentation for the most up to date faucet.
- OR, use the Goerli ETH Faucet, just be sure to swap your metamask to goerli!
