Hey HN! Author here. Some friends and I have been very inspired by the milliondollarpage back then, and we wanted to experiment with how flexible the NFT standard for Ethereum is. So we made this as an art experiment where you can mint and alter letters spread on a grid.<p>It uses ERC-721, which we previously criticized for the lack of compatibility with ERC-20 (see <a href="https://blog.citymayor.co/posts/why-the-standardization-of-erc-721-is-a-bad-idea/" rel="nofollow">https://blog.citymayor.co/posts/why-the-standardization-of-e...</a>). It turns out that NFTs don't have to be fixed like baseball cards. If you have any questions on how the NFT is "alterable", or how we did this, shoot<p>It also makes use of the opensea NFT exchange to delegate trading to that platform.
