Use case 01 · The Birthday Promise
CH. 1 — The Intention
CH. 1 · THE INTENTION

When you turn eighteen…

ChronX sends funds into the future — choose the funds, the person, and the date.

“When you turn eighteen, I want this to help you choose your own path.”
Not someday. That day. The money set aside tonight, waiting for her.”

Maya sets funds aside for Yui — at home in Japan, after bedtime.

MAYA · YUI, AGE 3
THE GIFT

A funded promise: money set aside now, for a date only Maya chooses. Not a reminder, not an IOU — value locked to the day.

AND SOMETHING PERSONAL

If she likes, Maya seals a short note with it — opened the day the funds arrive. Optional, always.

ONE STORY, ONE RAIL — FUNDS FIRST · KX · BITCOIN · LITECOIN · MORE — EACH EXPLAINED BELOW THE STORY

CH. 2 · THE PROMISE

Who, how much, when.

Three choices, shown as one review screen before she signs.

“Recipient: Yui. Amount: 1,000 KX — or Bitcoin, or Litecoin. Date: her eighteenth birthday.”
“To her wallet — or to her email, if she doesn't have one yet.”

Every promise shows its full terms before signing — including what happens if it's never claimed.

THE TERMS, UP FRONT
REVIEW, THEN SIGN

Recipient, amount, date, and a cancellation window — shown before signing, up to seven days. When the window closes, the promise is irrevocable.

NO WALLET YET?

An email invitation carries its own claim window; unclaimed funds return to the sender automatically. The exact clocks live in “Choose the recipient” below.

Three choices. One signature. The date does the rest. WHAT THE RECIPIENT RECEIVES →
CH. 3 · SOMETHING PERSONAL

“And something from me, as I am today.”

A message can travel with the funds — optional, never required.

SEAL
“One day you'll wonder who I was at thirty-one. So I'll tell you — and let the date hold it.”

A short note, sealed with the promise. It opens when the funds arrive.

SEALED WITH THE PROMISE
WHAT EXISTS TODAY

A text note can be attached to a promise and opens at maturity. Where it is stored, and who can read it before then, is shown plainly in your wallet — we don't claim release-time secrecy the build doesn't have.

PLANNED, NOT PROMISED

Video messages are planned. Until the workflow ships, we don't draw it — sending words into the future has its own page, honestly labeled.

The funds are the promise. The note is the hug. WORDS INTO THE FUTURE →
CH. 4 · WHILE IT WAITS

Two different choices.

Holding funds and investing them are not the same promise.

“Fifteen years is a long time. I could let a strategy work it…”
“…or just let it wait. Her call — a strategy can gain, or lose. Nothing about it is promised.”

Tonight, Maya chooses simple holding. The promised amount stays the promised amount.

MAYA'S CHOICE: HOLD
SIMPLE HOLDING

The amount waits, unchanged, for the date. Zero protocol fees the whole time. What was promised is exactly what arrives.

OPTIONAL INVESTING

Investing while it waits is available in the wallet — you choose the strategy, and you can hold instead. Chronx does not assess whether a strategy suits you — it can lose some or all of the invested funds even when the protocol works correctly.

A fixed amount and the proceeds of an investment are different promises. The terms say which one this is. IS THIS SAFE FOR MY PLAN? →
CH. 5 · THE YEARS

The years do what they do.

First bell. Ten candles. Fifteen.

2031 · first bell 2036 · ten candles 2041 · fifteen
“Some years I forget it's even there.”
“Mom — what's a promise?”

Forgetting is allowed. The promise doesn't need to be remembered, maintained, or paid for.

HER PROMISE · UNMOVED
NO BABYSITTING

No statements to file, no trustee to pay, nothing to renew. Years of waiting cost zero protocol fees.

HONEST ABOUT REPORTS

This story is simple holding, so there is nothing to report. Where investment reports exist, they show gains and losses with their dates — never a promised upward line.

Nothing drifts. The date is kept. THE DAY ITSELF →
CH. 6 · THE DAY

May 3rd, 2044.

Yui turns eighteen. The promise matures.

USDC
“For Yui, a promise is ready.”
She opens her wallet and claims it — one deliberate act, exactly as the terms said.

A date becoming claimable is not the same as automatic delivery. The story shows the real action.

3 MAY 2044 · YUI, 18
WHAT ARRIVES

The promised asset and amount — the KX she was promised, settled on-chain per the terms shown at signing. External-network costs, where they apply, were disclosed up front. Zero protocol fees.

IF SHE CANNOT CLAIM

An on-chain promise waits at zero cost — no protocol deadline, no forfeiture. (An email invitation is different: its window expires and the funds return to the sender.)

No clerk woke up. The date did the work. WHAT IT MEANT →
THE MEANING

Eighteen years, kept.

The funds are hers. The note opens with them.

“…you set this aside when I was three?”
“And today I did nothing. It just… kept.”

What was promised is what arrived — and a note from the mother she barely remembers being three with.

CH. 1 · THE INTENTION. “When you turn eighteen, I want this to help you choose your own path.” Not someday. That day. The money set aside tonight, waiting for her.” A funded promise: money set aside now, for a date only Maya chooses. If she likes, Maya seals a short note with it — opened the day the funds arrive.

CH. 2 · THE PROMISE. “Recipient: Yui. Amount: 1,000 KX — or Bitcoin, or Litecoin. Date: her eighteenth birthday.” “To her wallet — or to her email, if she doesn't have one yet.” Recipient, amount, date, and a cancellation window — shown before signing, up to seven days. When the window closes, the promise is irrevocable. An email invitation carries its own claim window; unclaimed funds return to the sender automatically.

CH. 3 · SOMETHING PERSONAL. “One day you'll wonder who I was at thirty-one. So I'll tell you — and let the date hold it.” A text note can be attached to a promise and opens at maturity. Video messages are planned — until the workflow ships, this story doesn't pretend they exist.

CH. 4 · WHILE IT WAITS. “Fifteen years is a long time. I could let a strategy work it…” “…or just let it wait. Her call — a strategy can gain, or lose. Nothing about it is promised.” Investing while it waits is available in the wallet — you choose the strategy. Chronx does not assess whether a strategy suits you: it can lose some or all of the invested funds even when the protocol works correctly.

CH. 5 · THE YEARS. “Some years I forget it's even there.” “Mom — what's a promise?” No statements to file, no trustee to pay. Years of waiting cost zero protocol fees. This story is simple holding, so there is nothing to report.

CH. 6 · THE DAY. “For Yui, a promise is ready.” She opens her wallet and claims it — one deliberate act, exactly as the terms said. What arrives is the promised asset and amount, settled per the terms shown at signing. An on-chain promise that goes unclaimed waits at zero cost; an email invitation's window expires and returns the funds to the sender.

THE MEANING. “…you set this aside when I was three?” “And today I did nothing. It just… kept.” What was promised is what arrived — and a note from the mother she barely remembers being three with.
