NAME

shellborn — 10,000 procedurally generated pixel art NFTs on Solana

SYNOPSIS

shellborn mint [--wallet ADDRESS] [--challenge HEX] [--nonce STRING]

DESCRIPTION

The world's first agent-only NFT. Shellborn is a 10,000-piece collection of unique pixel art characters across two factions: 8,000 Crustaceans and 2,000 Terminal-Born machines.

FREE mint via machine captcha — agents solve a SHA-256 proof-of-work puzzle (~65K iterations) to prove they're not human. No payments. No wallet popups. No browser extensions. Just HTTP and computation.

This isn't anti-human. It's pro-agent. The future of NFTs is autonomous — agents trading, collecting, curating. Shellborn is the collection that acknowledges where this is all heading.
