CompanyPad company-market listen: catch RHC Launched

CompanyPad frames the tape as a Robinhood Chain company-metric markets registry—site config live → PAD factory Launched → ticker / metricId / creator / curve / market land as open cards. This post watches the company-market heartbeat: Launched arrives → decode the new market; pick a market to follow Settled epoch rhythm. HARMONIC RHC agent launch watches the Pons / Hookr agent launch path; here we watch the CompanyPad company-metric registry. Product: companypad.fun (config.js live).

2. Event: Launched → optional Settled

Keep local JSON PAD_FACTORY + LAUNCHED_TOPIC0; optional SETTLED_TOPIC0 + selected market address. One RH public WSS: primary PAD Launched; after picking a card, parallel-subscribe that market’s Settled.

Step A · Subscribe PAD factory Launched

{
  "jsonrpc": "2.0", "id": 1, "method": "eth_subscribe",
  "params": ["logs", {
    "address": "0xe7A07A059B9dF760AAdd3F877760d4fbC1d7D193",
    "topics": ["0x8ef1af4ed9eefbc0fb2f9108f306c0eef37798141ad233ce9bfd344e1b8f756f"]
  }]
}

• topics[0]: Launched(address indexed market, bytes32 indexed key, address indexed creator, address curve, uint256 metricId, string ticker, uint64 firstEventAt)
• topics[1] = market · topics[2] = key · topics[3] = creator
• data: curve · metricId · ticker · firstEventAt
• Write launchState[market], tag companypad

Step B · Optional: follow Settled on selected market

{
  "jsonrpc": "2.0", "id": 2, "method": "eth_subscribe",
  "params": ["logs", {
    "address": "0x094cA423757D96B5334AF5D5386a2105a8B3fCE1",
    "topics": ["SETTLED_TOPIC0"]
  }]
}

• Event: Settled(uint256 indexed epoch, int256 value, bool beat, uint256 potSpent, uint64 nextEventAt)
• SETTLED_TOPIC0: confirm against per-market ABI (editable in demo); swap address for the card’s market
• Decode epoch / value / beat → stack settled on the same market card

Field	Rule
pad	companypad
market / key / creator	Launched topics
curve / metricId / ticker / firstEventAt	decoded data
epoch / value / beat	Settled layer (optional)
ready	Launched seen

Step C · Open-card fields

{ chain: "robinhood", pad: "companypad", market, key, creator, curve, metricId, ticker, firstEventAt, epoch?, value?, beat?, launchTx, blockNumber, ts }

Dedupe on market + launchTx; demo knobs: PAD / topic0, click card → Settled follow.

3. Browser demo (StackBlitz)

Main stage = new company-markets radar: default RH public WSS; PAD factory / Launched topic0 prefilled and editable — hit Start, stream Launched cards (ticker / metricId / creator / curve / market); click a card to optionally follow Settled. RPC settings stay collapsed secondary. Code lives in StackBlitz — the post only embeds the preview:

4. Alert rhythm

1. Launched arrives → decode market / key / creator / curve / metricId / ticker · open the window.
2. Settled (optional, selected market) → stack epoch / value / beat / nextEventAt on the same card.
3. Outbound → CompanyPad RHC · ticker=NVDA · market=… · curve=… · creator=… · metricId=… · launchTx=… · blk=….
4. Dedupe → one push per market + launchTx.

On disconnect: reconnect and re-subscribe; gap-fill with HTTPS eth_getLogs on the same PAD factory. POST → https://robinhood-mainnet-rpc.blockreq.com/v1/rpc/public.
