1. Status and acceptance
These Rules govern Ledger Hunt Phase One (the “Hunt”) from 7 October 2026 at 18:00 UTC. By participating or submitting a claim, a participant accepts these Official Rules.
The Hunt is decided by skill, judgement and knowledge. It is not a random draw, raffle, lottery or investment scheme.
2. Promoter
The public promoter name is ZLETZ. ZLETZ is the author and promotional name used by Zack Letang, who is responsible for the promotion.

The First Key NFT Terms govern the token and artwork. The Privacy Notice explains how personal information is used. These Rules control Hunt eligibility, verification and reward entitlement.
3. Who may participate
The Hunt is open to natural persons aged 18 or over internationally, except where participation, the required activity, or receipt of a cryptoasset is prohibited or restricted by applicable law. Persons subject to applicable sanctions, and persons in jurisdictions where the Hunt or reward is unlawful, are not eligible.
- One genuine account and no more than one Phase One First Key per natural person.
- Employees, contractors and household members who worked on the Hunt may not participate.
- Bots, claim farms, false identities and submissions made for another person are not permitted.
- Participants are responsible for checking whether participation and receipt, holding or resale of the NFT are lawful where they live.
The Promoter may decline or pause a claim where reasonably necessary to comply with sanctions, court orders or other applicable law.
4. Opening, duration and closure
- Opening
- 7 October 2026 at 18:00 UTC (7:00 pm UK time)
- Minimum guaranteed operating date
- 7 October 2028 at 18:00 UTC
- Current status
- OPEN
Phase One has no fixed winner pool and no closing date is currently announced. It will remain available until at least the minimum guaranteed operating date above. If a later closing date is set, the Promoter will give at least 180 days' advance notice unless law, safety, security or an event beyond reasonable control makes that impossible. Claims submitted before an announced closing time will still be reviewed.
5. No separate entry fee and lawful access
There is no separate claim fee and no proof of purchase requirement. Solving Phase One requires lawful access to the ten participating paperback books and official Ledger City material. Books may be bought, borrowed, received as a gift or accessed through another lawful source.
Participants pay their own ordinary costs, including any books they choose to buy, internet access, devices, travel, accommodation, taxes and optional marketplace or later blockchain fees. Spending more does not create priority or lower the verification standard.
6. How Phase One works
A valid claimant must independently solve the connected Phase One puzzle, follow the resulting lawful instructions, and submit the evidence requested by the official claim portal. The public Rules will not publish the answer.
- Sign in to the official Website claim portal.
- Request a unique challenge code, expected to expire after 24 hours.
- Submit the requested solution, concise route explanation and genuine proof before the code expires.
- Confirm age and the declarations displayed in the form.
The proof image will not require the claimant's face. Claimants must avoid including bystanders, vehicle plates, home addresses or other unnecessary personal information. AI-generated, composited, materially altered or borrowed proof is invalid. Ordinary cropping, rotation and brightness correction are permitted only where they do not alter the evidence.
7. Verification and review
Complete claims will be assessed manually against a documented private answer key and evidence checklist. Correct wording alone will not be enough where the Rules require an explanation or genuine proof. No random selection is used.
- The Promoter may request clarification or replacement proof if a submission is incomplete or reasonably suspected of manipulation.
- The target for an initial decision is 30 days after receipt of a complete claim. More time may be needed for complex fraud, sanctions or accessibility checks.
- Approval is final only when recorded in the claimant's Website account.
- A rejected claimant may request one internal review within 30 days by emailing support with the account email and decision reference.
8. The First Key reward
Every complete and valid claimant approved under these Rules becomes a “Verified Solver” and is entitled to one numbered Ledger City First Key NFT. There is no fixed number of winners and no race for a single prize.
- Identifiers use six digits, beginning FK-000001 and continuing sequentially.
- The number is an administrative identifier, not a promise of rarity, monetary value, rank, seniority or future benefit.
- Numbers are assigned after verification in the order complete valid claims are recorded, subject to correction of genuine processing errors.
- The supported initial issue is free and the Promoter intends to pay the ordinary gas cost for that first mint or delivery.
- There is no cash alternative.
An approved claimant must provide or connect a compatible Base wallet within 30 days after approval, unless support confirms a reasonable extension. The Promoter will never ask for a seed phrase or private key.
9. Transferability and Phase Two
The NFT may be kept, gifted, transferred or sold subject to the NFT Terms, marketplace terms and applicable law. A later holder becomes the Current Custodian of the token only.
Transfer of the NFT does not transfer the original claimant's Verified Solver status, Website account, certificate, Phase Two access, puzzle progress, claim history, personal information or eligibility for a future reward. Those remain with the original approved claimant.
Phase Two, currently titled “The Empty Wallet”, will have separate launch details and may have separate rules. Phase One does not promise a particular future prize or investment return.
10. Hall of Key Holders
Any public Hall of Key Holders will be optional and based on separate consent. A solver may choose an alias and Key number without publishing a legal name, email address or wallet address. Declining publicity does not affect a claim. Public blockchain records cannot be erased by the Promoter.
11. Safety and lawful conduct
- Use only places lawfully open to the public and follow signs, barriers, opening hours and instructions.
- Do not trespass, climb structures, enter roads or rail areas, dig, remove or mark anything, touch or alter a Hunt marker, block paths, or fly a drone.
- Pause participation in unsafe conditions. No solution requires unsafe or unlawful conduct.
- The Promoter does not arrange travel. Participants are responsible for travel documents, insurance, accessibility planning and personal safety.
A participant who cannot reasonably complete a standard proof step because of disability or another protected accessibility need may contact support before submitting. A reasonable alternative may be offered where it tests substantially the same knowledge without disclosing the solution.
12. Disqualification
A claim may be rejected or revoked on reasonable evidence of multiple identities, false or borrowed proof, generated or composited evidence, unauthorised access to the answer key, interference with the Website or Hunt material, bots, harassment, unsafe conduct, material breach of these Rules, or a legal restriction on delivery.
Sharing theories and ordinary collaboration are part of the fun. Each claimant must nevertheless satisfy the verification standard personally and submit their own genuine evidence.
13. Technology, tax and changes
The Promoter will take reasonable steps to keep the Website, claim process and Hunt material available but cannot promise uninterrupted access. Network congestion, wallet incompatibility, outages, cyberattacks, loss or damage to Hunt material, severe weather, public restrictions or legal change may require a pause or equivalent replacement method. A fair update will preserve valid progress as far as reasonably possible and will not replace skill with a random draw.
Participants are responsible for any tax, valuation or reporting obligation arising from receipt, ownership or resale of the NFT. The Promoter does not provide legal, tax, financial or investment advice.
14. Liability and governing law
Nothing in these Rules excludes liability that cannot lawfully be excluded, including liability for fraud, death or personal injury caused by negligence, or mandatory consumer rights. Subject to that, the Promoter is not responsible for loss caused by a participant's unlawful or unsafe conduct, travel choice, disclosure of wallet credentials, marketplace transaction, third-party service or event outside reasonable control, to the fullest extent permitted by applicable law.
These Rules and non-contractual matters are governed by the law of England and Wales. The courts of England and Wales have non-exclusive jurisdiction. This does not remove mandatory consumer protections or a right to bring proceedings in a participant's home jurisdiction where local law grants that right.
15. Personal information
Information is used to operate and secure the Hunt, verify claims, issue First Keys, provide eligible Phase Two access, answer support requests and meet legal duties. Optional publicity and marketing require separate choices where applicable. See the Privacy Notice.
