# Solidity Contract Template based on CoolCatsNFT [@coolcatsnft](https://twitter.com/coolcatsnft)

Source: [https://etherscan.io/address/0x1a92f7381b9f03921564a437210bb9396471050c#contracts](https://etherscan.io/address/0x1a92f7381b9f03921564a437210bb9396471050c#contracts)

The CoolCatsNFT contract is very well written and very gas efficient.
Consider using this approach if you're creating NFTs off-chain.
Can cost as low as $100 at 14 October 2021 ETH Price of $3,527.
CoolCatsNFT team deployed this contract for $55.59 at $1,983 ETH Price from 27 June 2021.

The trick is to just use \_safeMint without using \_setTokenURI at all. Hence no ERC721Metadata.sol imported.
tokenURI function will just concatenate the baseURI with the token id when calling the function.
