Follow and tweet me if Faucet is not working, and I will transfer some ETH.
- Start with Solidity as a language. Dapp University has an amazing course on it to get you started.
OpenZepplin is the go-to library for secure smart contract development.
ERC20: Coins like Dogecoin, and USDC follow this standard. https://ethereum.org/en/developers/docs/standards/tokens/erc-20/
ERC721: NFTs. Period. https://ethereum.org/en/developers/docs/standards/tokens/erc-721/
You will find the base token standard code in the OpenZepplin library and much more as you start reading the contracts. Spend as much time as you can writing new contracts and reading various standards and contracts.
As a practice, start bookmarking whatever trustworthy links you find and have done your research, the Internet is a dark and untrustworthy place, you have to start relying more on the blue star in your browser to ensure you are on the right website. Scammers do usually run google ads on popular web3 products/websites and one misclick and you can compromise all of your security.
