These terms are an agreement between you and Mauricio Eastmond, the individual who operates the Once Upon a Bit website (“we” and “us”). Once Upon a Bit is operated by an individual, not a company, so these terms name the person responsible. They took effect on 2026-08-08. By creating a gift, funding a gift, or purchasing a storybook unlock, you agree to them. A gift is claimed by a child with an adult present; the adult accepts these terms on their own behalf, and no contract is formed with the child.
1 · What Once Upon a Bit is
Once Upon a Bit is a website for gifting small amounts of bitcoin to children, together with illustrated storybooks that teach what bitcoin is. An adult chooses a story, funds the gift from their own wallet, and shares a claim link; the child reads the story and, with an adult, moves the coins into a wallet of their own. This is the entire service.
Our servers have a narrow role. They store the details an adult enters when creating a gift, watch the gift’s public address so the page can show its status, and pass the signed claim transaction to the bitcoin network. They cannot spend, freeze, or recover any bitcoin: the only key that can spend a gift never reaches our servers. It travels inside the claim link, on your side.
We are not a bank, an exchange, a broker, a custodian, a trustee, a fiduciary, or a party to your gift. We do not buy, sell, hold, or convert bitcoin, and we do not accept money on anyone’s behalf. At no point do we take possession of the bitcoin in a gift.
2 · You must be 18
You must be at least 18 years old to create a gift, fund a gift, or purchase a storybook unlock. The claim experience is designed for a child to use with an adult present; no contract is formed with a child.
3 · The gift key
Each gift has its own newly generated bitcoin key. In the software as published, the key is created in your browser and travels inside the claim link after the “#” symbol — a part of a web address that browsers do not send to servers. Our servers store the gift’s public address and never receive the key.
4 · The claim link is a bearer instrument
Whoever holds the claim link can claim the gift. It functions like cash in an envelope and should be treated accordingly. Before you fund a gift, we require you to confirm that you have saved the link, and we record that confirmation.
Because we never hold the coins, we cannot cancel, refund, or reverse a gift. An unclaimed gift can be swept back by you, using your own copy of the claim link.
5 · Storybook unlocks
Gifts are free. The only thing we sell is a one-time US$2.99 unlock of the full storybook library for a single gift’s claim link, paid in bitcoin to an address we control. The price is quoted in satoshis and fixed for 24 hours from the moment you begin the purchase.
Refunds are not automated. Sending bitcoin from an address requires that address’s private key, and our servers hold no private keys: library payment addresses are derived from a public key, so our servers can detect a payment but cannot spend it. The private keys stay in the operator’s own wallet, and any correction is made manually by the operator, from that wallet.
6 · Acceptable use
You agree not to use Once Upon a Bit to:
- move proceeds of crime, or funds intended for any unlawful purpose;
- evade sanctions, or access the service from a jurisdiction we block — access is restricted by region, and you may not circumvent those restrictions;
- attack, overload, scrape, or probe the service, or attempt to access data belonging to gifts that are not yours;
- create gifts in bulk with automated tools, or enumerate, guess, or harvest gift or claim links that were not shared with you;
- resell, white-label, or route third-party volume through our transaction relay.
You confirm that you are not subject to US sanctions and are not acting on behalf of any person or entity that is.
If you violate these rules, we may block or limit your access to the service. We cannot freeze, seize, or reverse anyone’s bitcoin, because we never hold it.
7 · No warranty
Bitcoin’s price is volatile. Nothing on this website is financial, investment, or tax advice, and nothing here is a prediction of bitcoin’s future value. The bitcoin network charges its own transaction fees, which we do not receive and do not control.
8 · Limitation of liability
The US$100 minimum corresponds to the maximum gift amount on this website. Because creating and claiming gifts is free, a cap limited to amounts paid to us would be zero for most users.
We never hold your coins, so a gift lost with its link, or taken by someone who obtained the link, is not something we cause, control, or can undo (see Section 4).
9 · Disputes: individual claims only
Small claims are preserved. Either party may bring an individual claim in small-claims court. These terms do not impose mandatory arbitration. Where the law does not allow this waiver for a particular claim — under California law, for example, the right to seek a public injunction cannot be waived — the waiver does not apply to that claim, and the rest of these terms is unaffected.
Before filing any claim, please contact mauricio@onceuponabit.com; most issues can be resolved directly.
10 · Governing law
These terms are governed by the laws of the State of California, USA, without regard to its conflict-of-laws rules. The state and federal courts located in California are the venue for any dispute not brought in small-claims court.
Access to the service is restricted by region. If you access it from a blocked region, or from a place where any part of the service is unlawful, you may not use it.
11 · The storybooks
The storybooks, illustrations, and text are © 2026 Mauricio Eastmond. All rights reserved. A storybook unlock grants reading access on the claim link for which it was purchased; it does not transfer ownership or permit redistribution, resale, or republication of the books or artwork.
12 · Changes to these terms
We may update these terms. Because the service has no accounts and we hold no email addresses, we cannot notify you individually. Each version carries an effective date, and the version in force when you acknowledged a gift is recorded with that gift and never rewritten. Changes are not retroactive.
