I'm trying to airdrop NFTs to token stakers

Hey guys, I’m trying to create a smart contract that will allow ERC20 token stakers to mint an NFT,

Is it possible and how can i achieve this,

Thanks.

Yes that is possible. You could have your staking/ERC20 contract and NFT contract, and in your NFT contract, restrict (with require) the minting process to token stakers only (determined by reading data from the staking contract).

can you please help me to audit this code

I’m trying to create a modifier in the saitanobi (NFT) contract below

so that it will allow only the stakers of the token to mint one NFT each.
