NFTTerms.

1. Parties and acceptance

These terms are issued by Zack Letang, using the author and promotional name ZLETZ (the “Issuer”). They apply to every official Ledger City First Key non-fungible token and every person who receives, holds, transfers, lists, buys or otherwise acquires one.

These Terms take effect on 7 October 2026 at 18:00 UTC. By accepting or acquiring an official First Key, a holder accepts these NFT Terms.

2. Key definitions

• Artwork means the visual Ledger City key artwork and approved metadata linked to a First Key.
• Current Custodian means the person controlling the blockchain address that currently owns the token, subject to reasonable proof.
• Verified Solver means the natural person whose Phase One claim was approved under the Official Rules.
• Website Account means the separate off-chain account containing claim status, certificate, progress and any Phase Two entitlement.

A First Key number is an administrative identifier only. It does not guarantee rarity, rank, value, seniority, access or future reward.

4. Free supported first issue

Each Verified Solver is entitled under the Official Rules to one free supported initial First Key. The Issuer pays the ordinary gas cost for the supported first mint or delivery. A token is minted only after the claim has been manually verified and approved. The solver must provide or connect a compatible Base wallet within 30 days after approval, unless support confirms a reasonable extension, and must never provide a seed phrase or private key.

The delivery flow may use a claim signature, sponsored transaction, smart account or direct transfer. A failure to complete token delivery does not by itself erase the off-chain Verified Solver status.

5. Transfer and resale are permitted

Subject to applicable law and these Terms, a Current Custodian may keep, gift, transfer, list or sell the First Key through a compatible wallet or marketplace. The Issuer does not set or guarantee a resale price, buyer, market, liquidity or marketplace availability.

A later transaction is between the seller, buyer and any marketplace they use. Unless the Issuer is expressly identified as the seller, the Issuer is not a party to that transaction, does not hold the parties' funds and does not guarantee performance. The parties are responsible for gas, marketplace charges, payment disputes, tax, reporting and local-law obligations.

6. What transfers with the NFT

Original Solver status and Phase Two access remain with the original approved Website Account after the NFT is transferred. They cannot be sold by transferring the token.

7. Artwork licence

The Issuer or its licensors retain intellectual-property rights in the Ledger Hunt names, logos, world, characters, map, key design, Artwork and metadata, except for ownership of the specific blockchain token.

While a person is the lawful Current Custodian, that person receives a worldwide, non-exclusive, royalty-free licence to display the unaltered Artwork for personal, non-commercial purposes, use it as a personal profile image, show it in a personal collection, and display it as reasonably necessary for a lawful transfer of the corresponding NFT.

The licence does not permit commercial merchandise, paid advertising, sponsorship, sublicensing, copying or minting a derivative token, use as a trade mark, false endorsement, or exploitation of the Artwork separately from the token without written permission. The licence passes to the next lawful Current Custodian when the token transfers and ends for the former holder.

8. Creator royalty signal

The contract signals a creator royalty of 2.5%. A royalty standard communicates royalty information but does not force a marketplace to pay it. Marketplaces may ignore, replace or separately enforce royalties, and no holder is promised that a royalty will be collected.

9. Blockchain, wallet and marketplace risks

• Blockchain transactions may be irreversible. Sending a token to the wrong address can permanently lose control.
• Loss or disclosure of a seed phrase, private key, device or authentication method can lead to theft. The Issuer never asks for a seed phrase or private key.
• Contracts, wallets, marketplaces, bridges, network providers and storage systems may contain bugs, suffer attacks, change terms, suspend service or stop supporting the NFT.
• Gas prices, standards, royalties, law and tax treatment may change.
• Wallet addresses, token IDs, ownership and transfers may be permanently public and analysable.
• Counterfeit links and collections can look convincing. Verify the official contract on this Website before signing anything.

10. Custody, loss and support

The Issuer does not control a holder's self-custody credentials. A holder is responsible for wallet security and recovery methods. The Issuer does not promise to reverse transfers, restore a lost token, reimburse theft or replace a First Key sent to an inaccessible address. Technical support may help diagnose an issue where possible but will never request credentials or guarantee recovery.

11. Metadata and availability

The Issuer intends to preserve the official Artwork and metadata and may correct broken links, security defects, inaccurate descriptive fields or display compatibility where reasonably necessary. Permanent availability cannot be guaranteed because networks, gateways, storage providers and standards may fail or change. A replacement gateway or archival copy may be provided where it preserves the same Artwork and token identity.

12. Prohibited conduct

A holder must not use a First Key or related service for fraud, theft, money laundering, sanctions evasion, unlawful market manipulation, wash trading, counterfeit collections, phishing, malware, infringement, harassment, false endorsement or circumvention of a lawful restriction. The Issuer may remove access to off-chain services, withdraw the Artwork licence for a material breach, report conduct or take other lawful action. The Issuer cannot erase a valid blockchain transaction.

13. Sanctions and tax

No person may claim, transfer or acquire a First Key where that would cause a party to breach applicable sanctions or law. The Issuer may screen public wallet addresses and pause off-chain delivery while carrying out a proportionate review. Each recipient and holder is responsible for tax, valuation, record-keeping and reporting obligations.

14. Consumer rights and liability

Nothing in these Terms excludes a right or 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 token, Artwork and related services are provided on an “as available” basis. To the fullest extent permitted by applicable law, the Issuer is not liable for loss caused by market price change, a secondary transaction, wallet compromise, mistaken address, third-party service, network failure or conduct outside reasonable control.

15. Changes, law and disputes

The Issuer may update these Terms prospectively for legal, regulatory, security, technical or clarity reasons. A material change will be announced with an effective date and will not retrospectively remove blockchain ownership or a licence use already lawfully completed.

These Terms and non-contractual matters are governed by the law of England and Wales, whose courts have non-exclusive jurisdiction. This does not remove mandatory consumer protections or a right to bring proceedings in a consumer's home jurisdiction where local law grants it.
