MercadoNFT

Mercado NFT is a decentralized marketplace that allows users to list, buy, and sell NFTs.This ensures a secure, transparent, and efficient platform for digital asset transactions. This marketplace uses Pinata to upload NFT images to IPFS and indexes emitted events into a graph database for faster querying, eliminating the need to repeatedly query the blockchain for fetching NFTs.

Features

• Decentralized Marketplace: List, buy, and sell NFTs seamlessly.
• Pinata Integration: Upload and store NFT images on IPFS for decentralized and reliable storage.
• Graph Database Indexing: Efficiently indexes events into a graph database, providing a faster and more efficient querying system without the need to constantly query the blockchain.
