AI assisted coding gives you super powers if you know at least one language really well and understand the fundamentals. Like, I've never written a word of Solidity, but I can totally understand and debug it when AI writes it for me.

Let me know if you'd like another quick pair of eyes. :) Worth going through articles like these (there's like a couple dozen of them) if you're doing anything with actual value: https://docs.soliditylang.org/en/latest/security-considerations.html

I have a ton of questions! Right now I'm not doing anything high stakes. My frame lets two people play a chess game, at the end you have an option to mint an NFT with the metadata of the game and players and a photo of final board position. This is what I've figured out so far: - when a game ends, ask user if they want to mint an NFT. - if I want to charge exactly 0.1 USDC for the NFT, I calculate the current eth exchange rate off chain using some API (?) and then use that amount to initiate transaction. - if yes, using Warpcast sdk, initiate transaction (this is on client side and prompts user to approve transaction). - once approved, this transaction is directly sent to a smart contract. - This contract then issues an NFT to the sender. - Q: should I, can I, send metadata in the transaction that user send to the contract? Or can I just issue a blank NFT initially, save that token address on my backend, and then update NFT metadata. Is it possible to update NFT metadata after minting?

How much do you care about the user being able to mint whatever metadata at whatever cost? Anything you want "enforced" needs to be onchain or signed by some "oracle" (trusted party) Getting USD/ETH rate in solidity is not too hard. ENS does something similar if you want a production example. Another option is using an AMM pool like one of the Uniswap ones to get a price, eg https://docs.uniswap.org/concepts/protocol/oracle (We generally refer to anything that serves as a source of truth as an "oracle")
