8004 NONCE

how to mint & stay safe - main site ยท classic 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. Official pages: 8004nonce.eth.limo (ENS: 8004nonce.eth) and its Arweave mirror daemon-8004nonce.ar.io — anything else is a copy.

Method 1 - the mint page (easiest)

  1. Open the main page (or the minimal classic mint page) and click Connect wallet (Ethereum Mainnet).
  2. Press start mining and watch the bits climb. It stops at the first valid nonce (16 bits is the minimum), or pick a higher target first; more is your choice. On the classic page, press Mine.
  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. Skip Connect wallet and paste your wallet address instead (main page: mine for this address; classic page: mine without connecting).
  2. Mine, then copy the mint packet it shows you: to, value, data. Send it on Ethereum mainnet from that same address - the nonce only works for the address it was mined for.
  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.
