01 The problem
Most NFTs point to images on IPFS or a server. If that host disappears, the NFT is just a broken link.
PixelCard stores SVG artwork as strings in the contract and builds the metadata on demand in tokenURI(), so the art lives exactly as long as the chain does.

03 What I built
- 01Rarity tiers of Common 60%, Rare 30% and Legendary 10%, with graceful fallback when a tier sells out instead of reverting.
- 02A custom Base64 encoder and on-demand SVG → JSON encoding.
- 03Paid minting, a 100-token cap, and separate deployer and owner addresses.
- 0494% test coverage.
