Compressed NFTs

This repo contains scripts to create compressed NFTs. Compression is a new technology using Merkle tree wich allows to reduce network storage costs. In the case of NFTs, compression enables the mint of NFTs for a fraction of the cost as before. You can learn more about compression here and here. For an explanation of how scripts work, you can read this medium article
