Prediction-market sandbox
Five CPI outcomes. One official resolution.
Pseudonymous wallet-style paper market for Japan CPI. Pick 1.5%, 2.0%, 2.5%, 3.0%, or 3.5%. After official CPI data, the winning bucket receives the book minus a 1% CPI service fee.
Wallet game identity
Zweichain EVM wallet
Connect a MetaMask-style provider to use a pseudonymous wallet identity. CPI orders remain game signals only until token, contract, and legal gates are cleared.
Game mode only: wallet connection never asks for private keys, does not sign orders, does not transfer ZWC/CPI, and does not create redeemable payout rights.
