While the transfer lock is on, CHANCE can’t be bought from another wallet — it enters circulation through protocol paths only.

​
1. Claim a winning bet as CHANCE

The primary player path. When claiming a win, pass claimAsChance = true: the full USDG payout is spent buying CHANCE on the Uniswap V4 pool in the claim transaction, and the CHANCE is delivered to your wallet.
  • Set minChanceOut as your slippage floor — the claim reverts InsufficientChanceOut below it.
  • The entire payout converts; there’s no partial buy or USDG remainder.
  • Full mechanics: Claiming.

​
2. Staker CHANCE rewards

Stakers in CHANCE reward mode accrue their share of house wins as claimableChance inventory on ChancePool, withdrawable any time with claimStakerChance(amount). See Staking rewards.

​
What about direct buys?

USDG→CHANCE swaps on the V4 pool are gated by the hook: external buys are disabled by default (externalBuysEnabled = false), and the pool’s own internal buy path handles claims and rewards. Unless a deployment explicitly enables external buys, don’t build UX that assumes users can market-buy CHANCE.
Sells are the asymmetry: CHANCE→USDG through the router is always open, even under the lock. See Selling.
