Flagrant

Quick question, wrote an airdrop contract to reward some holders of some token. Is there a max to how many addresses i can iterate over and transfer tokens to?

Running out of gas when trying to airdrop to more than 300 addresses or so. Any ideas or loopholes to airdropping to a larger set of addresses?

Want to make a smart contract that makes me rich, how do i do that with solidity 0.6.12 ser 🤓?

lets say i have a contract address - how can i programatically figure out if its an ERC1155 or ERC721 contract?

Also where do u define the mapping, u sure its address to uint?
