BaseStonk launchpad listen: AdvancedLaunched open cards

BaseStonk fee-leaderboard heat puts the Base stock-token pad on the tape—factory fires → AdvancedLaunched → token / creator / poolId / pairToken / tax·burn·liquidity bps land as open cards; optional RewardsEnabled stacks the holder-rewards chip. Base new-pool sniper watches PairCreated / Swap spikes; OpenLaunch one-tx watches v4 Initialize + full-supply-to-pool; LAPTOP liquidity detector watches first Mint/Swap; stock-token Swap watch watches whitelist big prints. This post watches the AdvancedLauncherV2 factory radar (full open-card fields).

2. Event: AdvancedLaunched

Keep local JSON LAUNCHER + ADVANCED_LAUNCHED_TOPIC0. One Base public WSS: primary factory AdvancedLaunched; stack tax / burn / liquidity bps on the card. Optional secondary chip: RewardsEnabled.

Step C · Open-card fields

Outbound card first: token · creator · poolId · pairToken · taxBps · burnBps · liquidityBps · payees · launchTx · blockNumber. RPC / endpoint stays in a collapsed secondary rail.
