HACKHOOD

Mint gate

No allowlist. No presale. One cipher.

The contract does not care who you are. It cares whether you can break things. One puzzle is drawn at random from a pool of one hundred thousand and bound to your session permanently — no reroll, no second draw, no easier hand. Break it and the mint opens.

• Difficulty — real cryptanalysis. Wiener, Håstad, Pohlig–Hellman, nonce reuse. Expect to write code.
• Attempts — 20 per puzzle. Guessing 2⁶⁴ is not a strategy.
• Answer — the 16 hex characters inside HACKHOOD{…}.
