SingleNFTFactory

Mint a 1 of 1 NFT with its own contract for ~90k gas.

Deployed to Ethereum mainnet: https://etherscan.io/address/0xc88891560074f477590b7f6109fe62cb26159469#writeContract

Also on Polygon (sooo cheap): https://polygonscan.com/address/0x4ad315ea13517a71880ff8c1a58ab8ed73c6c541#writeContract

Note, you need to turn all strings into bytes before writing. This site can help just make sure to remove the spaces and add 0x.
This was done to avoid doing string manipulation on-chain.
