Overview
Section titled “Overview”CHAN is the player channel manager that coordinates YUE (player banks) and handles opt-in mechanics for game contracts. It provides controlled access to player funds through the whitelist system.

Immediate Parents
Section titled “Immediate Parents”What This Means For Players
Section titled “What This Means For Players”Plain English Summary: CHAN is the player manager - it controls access to your bank (YUE). Before any game contract can touch your funds, you must explicitly opt-in through CHAN. This gives you granular control over which game features can access your tokens.
Real-World Analogy: Think of CHAN like the security settings on your bank account. You can authorize specific apps to access your account (opt-in) and revoke that access anytime (opt-out). No one can move your money without your explicit permission.
How It Affects Your Gameplay:
- Opt-in control - You decide which contracts can access your YUE
- YUE management - CHAN links your wallet address to your YUE bank
- Transfer safety - Withdrawals and transfers only work with opted-in contracts
- Account portability - You can transfer your YUE to a new wallet through CHAN
