Bucket RHC launchpad listen: catch Launched + routing flags

Bucket Shop’s launchpad wires new opens into a live Robinhood Chain payout engine—pad fires → factory Launched → token / creator / curve / founding land as open cards; after the curve climb, follow Graduated for pool lock/splitter. PONS one-pad converge watches dominance-era open listen; HARMONIC agent launch watches the Pons / Hookr agent launch path; CompanyPad company markets watches the company-metric registry. This post watches Bucket launchpad + holders/backing/buyback routing. Product: launch.bucketmarkets.com (config.js / abi.js live).

On-chain snapshot (indexer launchpad/launches + founding): founding 5 slots filled; live launches include BHC 0x2d2e5cb9319c3b893db80eb6f9e2cea386720cf9, INFINITY 0xbd305151d3d7eb612d3969e9fa05315cd47374e4, mostly phase climbing.

2. Event: Launched → optional Graduated

Keep local JSON LAUNCH_FACTORY + LAUNCHED_TOPIC0; optional GRADUATED_TOPIC0. One RH public WSS: primary factory Launched; after picking a card, parallel-subscribe the same factory’s Graduated (filter by token).

Step A · Subscribe factory Launched

{
  "jsonrpc": "2.0", "id": 1, "method": "eth_subscribe",
  "params": ["logs", {
    "address": "0x7Eb30f769403c6689944479b135620d674DEDCe3",
    "topics": ["0xe7c0e9df574006f71903192ae6dcdbbd6da1521746999feaae0225953f609ff8"]
  }]
}

• topics[0]: Launched(address indexed token, address indexed creator, address curve, uint256 tierId, uint256 id, bool founding)
• topics[1] = token · topics[2] = creator
• data: curve · tierId · id · founding
• Write launchState[token], tag bucket

Step B · Optional: same-factory Graduated

{
  "jsonrpc": "2.0", "id": 2, "method": "eth_subscribe",
  "params": ["logs", {
    "address": "0x7Eb30f769403c6689944479b135620d674DEDCe3",
    "topics": ["0xb1081ec269a8f1d91c258991f53f9733d4e48c29d67136040ff4bae163e23c19"]
  }]
}

• Event: Graduated(address indexed token, bytes32 poolId, address lock, address splitter, uint256 quoteSeeded, uint256 tokensSeeded, uint256 tokensRetired)
• topics[1] = token; stack poolId / lock / splitter on the same open card

Field	Rule
pad	bucket
token / creator	Launched topics
curve / tierId / id / founding	decoded data
poolId / lock / splitter	Graduated layer (optional)
ready	Launched seen

Step C · Open-card fields

Outbound card first: token · creator · curve · founding · id · launchTx · blockNumber. RPC / endpoint stays in a collapsed secondary rail.

3. Run in the browser

Main stage is the Launched radar card; RPC table stays collapsed. Register for 3M free requests monthly → blockreq.com.

4. Wrap

Bucket welds “launch” to a live payout engine on RHC: Launched gives frame one, Graduated gives the pool-lock frame. One public WSS subscribe and the open cards start printing.
