The problem Meme Bajaar solves

These are the tough times and a smile is all that matters. Meme culture is trending these days. Memers are doing a tremendous job. This is a crazy marketplace where memers get benefitted and followers show them love by collecting and trading memes. With this, creators get motivated and bring us more content.

Challenges we ran into

We have built this on top of Ethereum Blockchain where we used standard ERC721 Non Fungible Tokens. We built two smart contracts, ERC721 and NFT Marketplace. We faced challenges integrating both contracts. When we were calling ERC721 functions within NFT Marketplace functions, we were unable to fetch the function invoker addresses by msg.sender. Later we have gone through solidity docs and resolved this by using Tx.origin.
