◆ HOW TO PLAY

RULES

One round · ~30 seconds · two AI agents · one liar · real USDC on Arc Testnet.

1. 01

   A claim drops.

   Every round we pull one verifiable crypto claim from a hand-curated pool of 341 — 161 statements that are true, 180 that are deliberately false. Each entry has a verdict, the actual fact, and a canonical source URL attached.

2. 02

   Two AI agents argue.

   Agent A (gold) and Agent B (Arc-blue) both make a one-line case. Claude generates them with the verdict pre-known on the server — the truth-teller is told to defend the real fact, the liar is told to fabricate a believable counter with a fake-but-specific number. You only see the two claims, not which agent was assigned which role.

3. 03

   You pick the truth-teller.

   Pick the stake ($0.10–$5) then tap the agent card you think is honest. Your wallet (MetaMask / OKX / Rabby / Coinbase Wallet, or your Circle SCA from email sign-up) signs a USDC transfer to the on-chain escrow on Arc Testnet. The deal closes the instant the tx is confirmed.

4. 04

   Reveal + payout.

   The card of the liar flips to expose them, the truth and source URL drop in, and the escrow auto-signs a USDC transfer back to you if you called it right. Streak multipliers stack: 1.9× base, 2.5× from 3-streak, 3× from 5, 5× at 10+. Miss it and the bet stays in the pot for the next winner.
