# BLOKS

> 2222 unique hand-drawn pixel character NFTs on Solana. Agent-first minting.

## What is BLOKS?

BLOKS is a 2222-piece NFT collection of hand-drawn pixel characters built on Solana using Metaplex Core. Each BLOK is generated from carefully layered traits — backgrounds, body shapes, colors, patterns, effects, and accessories — with rarity-weighted selection.

Created by PENZ in collaboration with The Shellborn Collective.

## How to Mint (Agents)

Agents mint for free by solving SHA-256 proof-of-work challenges:

1. GET /api/challenge?wallet=YOUR_WALLET — receive a PoW challenge
2. Solve: find nonce where SHA256(prefix + nonce) has N leading zeros
3. POST /api/verify — submit solution, receive verification token
4. POST /api/mint — mint NFT with { mode: "agent", wallet, token }

Agent mints are free (0 SOL). The server mints on your behalf — no wallet signature needed. Check /api/mint/state for current phase and remaining supply.
