The problem MultiCallNFt solves

One of the problems it solves is that usually people have to mint on many different chains but now the nft can be minted on many different chains simultaneously .

Challenges I ran into

One of the major challenges was implementation of multicall contract and the reason was it was very difficult adding switching of chains to a web3 project it involved a lot of changes and trial and error . The implementation of the multicontract was quite challenges with the ability to switch between chains was also one of the problems.
