OneTimeLaunchHookTemplate

EthereumRegistered

Enforces one-time pool initialization and initial liquidity per token (currency1). When the buy gate is activated via the unprotected `bigInt()` function (callable by anyone), non-zeroForOne (buy) swaps revert unless `tx.origin` is in a deployer-managed allowlist.
