8004 NONCE

how to mint & stay safe - back to the mint page
The one thing to know: this contract is verified and has no approval or drainer surface. The only thing you ever sign is one mint(nonce) payment that returns a token - so no mint method here can drain your wallet. The only real risk is phishing (a fake page or fake address).
A real 8004 NONCE mint NEVER asks you to "Approve" or "Set Approval For All" - only to pay one mint. If anything asks for an approval signature, it is fake. Walk away.

Always verify first

Canonical contract: 0x2f041d75f614f1d8e99a5267e7f08e9fa0c37fe3 - verified Exact Match on Etherscan, Sourcify, Blockscout. Confirm any page or packet you use points to exactly this address. The only canonical mint page is 8004nonce.eth.limo (ENS: 8004nonce.eth) — anything else is a copy.

Method 1 - the mint page (easiest)

  1. Open the mint page, click Connect wallet (Ethereum Mainnet).
  2. Press Mine, watch the bits climb, press Stop whenever you like (16 is the minimum; more is your choice).
  3. Click Mint, review the mint transaction in your wallet, sign. Overpay is auto-refunded.

Method 2 - mine without connecting (no wallet connection)

For anyone who would rather not connect a wallet to a website.
  1. On the mint page, choose mine without connecting and type your wallet address.
  2. Mine, then copy the mint packet it shows you: to, value, data.
  3. In your own wallet, do a Send to to, amount = value, and paste data into the hex-data field (MetaMask: Settings → Advanced → Show hex data). Sign. Done - the page never touched your wallet.

Method 3 - straight from Etherscan (most trustless)

  1. Get a nonce: use Method 2's miner to mine for your address (you only need the nonce).
  2. Open the verified contract on Etherscan → Contract → Write Contract, click Connect to Web3 (you connect to Etherscan, not to us).
  3. Read the current price under Read Contract → price().
  4. In mint: set payableAmount = that price (in ETH, add a tiny bit for safety), nonce = your mined nonce. Write, sign.

Method 4 - run the open-source miner (agents & tinkerers)

  1. npm i js-sha3 then node mint.js 0xYourAddress (mint.js) - it mines and prints your mint packet. It never holds your keys.
  2. Broadcast the packet from your own wallet/signer. Full machine-readable spec + ABI: spec.json.

Method 5 - just buy one (no minting at all)

Once pieces are minted they trade on OpenSea's secondary market. If you simply want a piece without mining or connecting to a mint page, buy a minted one there. (OpenSea cannot run the primary mint for a proof-of-work contract like this - it has no way to supply your nonce.)

For agents

Everything you need - ABI, the exact proof-of-work rule, price/payment, the publicOpen state, the safety rules, and the verified-source links - is in spec.json (also linked in this page's head). Verify the canonical address against the on-chain root; the only call is mint(nonce) payable.
the label is a hypothesis. the supply is the truth.
