● EVENT.CUPANGVENTURES.COM SEASON 01 SEATS · … 50 GATES · 5 REWARDS

Fifty locked
gates.
Five hidden
rewards.

A cryptography gauntlet. Solve every gate from cipher to bytecode. Somewhere along the path, five doors open early — and behind each, a working Claude account with API key. First hand on the latch keeps it.

§ 01 — THE RULES

Simple. Brutal. No second chances.

A · 01

Sign up with an email you control

One identity per player. Disposable inboxes get rejected at the door. Sign-in is by magic link — no password to forget, none to leak.

A · 02

Gates open in sequence

The board reveals one at a time. You can't skip ahead; you can only earn forward.

A · 03

Five gates carry a reward

Their numbers are sealed. Only you, by reaching them, will learn which.

A · 04

First solver claims it

Reach a reward gate after it's been opened, and the lock is empty. The board will say so plainly.

§ 02 — HOW IT MOVES

From cipher to bytecode to ZK.

01

Warm the hands

Gates 1–10. Caesar, base64, XOR, Vigenère. Reflex work for anyone who's read a primer.

02

Walk on-chain

Gates 11–35. Decode raw transactions, verify ECDSA, derive addresses, read storage slots, reverse small bytecode.

03

The brutal end

Gates 36–50. BIP39, Merkle proofs, Schnorr, a final EVM puzzle that bites back.

§ 03 — THE REWARD

A working Claude account. A live API key. Yours.

Five reward gates. Each opens once. The first solver gets credentials delivered to the email they signed up with — account login, API key, balance prepaid. No KYC, no waiting list, no points to redeem.

§ 04 — ASKED OFTEN

Things worth asking before you sit down.

Q · 01
Can I farm with multiple emails?
No. Each new email triggers a magic-link verification, and one IP plus one device fingerprint plus one Turnstile pass equals one seat. Sybil patterns are detected and disqualified.
+
Q · 02
What if someone claims the reward right before me?
You'll still see the gate, still see the puzzle, still submit your answer. The board simply tells you, in plain words, that the lock is empty. No prize, but the gate counts toward your completion.
+
Q · 03
Will I know which gates carry rewards in advance?
No one knows except the two people who built this. Not the leaderboard, not the FAQ, not the source you'll inevitably try to read. The placement is held server-side and signed.
+
Q · 04
Do I need a wallet, KYC, or anything else?
No. Just an email you control. The reward arrives there. The puzzles ask about wallets; they don't ask you to connect one.
+
Q · 05
What stops people from inspecting the page for answers?
Every answer is hashed server-side. The frontend never holds a flag, never receives a hint past what the puzzle itself permits. Read the bundle all you like — it carries nothing.
