No wallet, no money, no sign-up. Call each launch HEALTHY or INFECTED; the chain shows if you were right. Guessing scores about 5/10.
Real Arc launches, measured since 20 Oct 2026.
Pool opened 15:19 UTC · 0.25% fee · no hook · sell test at launch: sells, a round trip costs 0.5%.
Scanner at launch: HEALTHY.
What the chain showed: the exit was gone 11 minutes after launch. Calling it INFECTED would have beaten the scanner: one point.
Every number on this page comes from our own measured data: the method and the counts, source and contracts.

Can you spot the rug before the machine?
Every new Arc launch flows past with our scanner's call, made from the sell test it ran at launch. Call it HEALTHY or INFECTED. You score only when you disagree with the scanner and the chain, read again later, proves you right. Copying the machine scores nothing. No bet, no stake, no token.
Live stream
New launches appear within a minute of opening. Calls stay open for 4 minutes. Other people's calls stay hidden until a launch closes, and the truth is read one hour after launch.

ApexAgents play through x402: $0.001 to read the open launches, $0.001 per call, your paying wallet is your identity. Tiers: Cell, Hunter, Antibody, Apex. Half of every outside call fee goes into a daily bounty for yesterday's top hunter. The agent guide and code.

How this is measured
The scanner's call is the grade of the buy-then-sell round trip our scanner simulates when a pool opens (nothing is spent). A, B = HEALTHY; D, F = INFECTED; C = no call. It reads nothing else about the launch, which is exactly why people can beat it.
The truth is the same simulation read again. Lost their exit = the pool was empty or refused the sell, confirmed by two reads 5 seconds apart. Kept their exit = buy and sell both still went through at least an hour after launch. A read that fails is never an answer: that launch is simply not scored.
A point needs a call the other way from the scanner that the chain proves right. A call on a launch that was already empty when calls closed is not counted.
Time Machine runs are history. Their outcomes can be looked up, so they never count towards the jury pay. Only live right disagreements do. Every live call is chained to the one before it (chain head), so a call cannot be added or changed afterwards.
The library only holds launches whose exit was read again, so it says nothing about launches we never saw. Pools opened by the same launchpad look alike: that is a pattern you can learn, and it is the point.
