Hashbits:
Monsters are mined, not minted.

Hashbits is the proof-of-work mint behind 1 000 pixel monsters. No mint button and no allowlist: your browser hunts for a hash with enough leading zero bits, you burn the HASHBITS cost of the current epoch, and the contract hands you the next Monster in line — six species, corrupted streetwear, cursed traits, drawn before the contract existed and sealed by a provenance hash. Hold it to earn $SPCX, or burn it for BITS.

Reward rail

Each deposit is split across every live Monster. Pending rewards follow the NFT on transfer. The current holder claims from the Monster page; burning pays pending rewards first.

Three steps, none
of them ours

Nothing here waits on a server, a signature, or a list. The whole path from electricity to Monster runs between your browser and one contract.

01 · Mine

Your browser hashes four things: your address, a nonce, the work behind the last Monster and a recent block. Nobody can steal the answer — your address is inside it. Nobody can prepare one in advance — the previous Monster is inside it too.

A hash below the target is a ticket. Approve the epoch cost, then submit it. The contract pulls and permanently burns HASHBITS before minting the next NFT. First come, one per block.

03 · Own #N

You get the next number, not a random one. All 1 000 monsters were drawn before the contract existed and their hashes are sealed on-chain; the queue decides which one is yours. Hold it to earn $SPCX, or burn it for BITS points and collect pending rewards.

The owner can set metadata, set future burn costs and deposit $SPCX rewards. Mining still requires valid proof of work, and every reward deposit is split by the contract.
