HARMONIC / Pons RHC agent launch radar (TokenLaunched)

HARMONIC / ChillTRD frames the tape as a Robinhood Chain agent-asset path—X + site launch → Pons / Hookr venue → wallet / LP / strategy vault. This post watches the launch heartbeat: Factory TokenLaunched (or Hookr launchpad / V4 Initialize) arrives → decode token / curve / deployer → open card. PONS one-pad converge watches a single pad; here we fold the agent launch path into an editable multi-venue screen. Live board: demos1 HARMONIC. Pair with Crossrate FX opens on the same RHC tape.

1. Hook: agent launch path × open card

Tape feel	On-chain signal	Watch
Pons curve open	Factory TokenLaunched	token · curve · deployer · pairToken
Hookr pool-first	Launchpad open / V4 Initialize	poolId · currency0/1 · hooks
Agent asset lands	First cluster in launch tx window	pad label + launchTx
Sniper tape	hit → outbound	Dedupe = token + launchTx

Venue	Contract (editable prefills)	Role
Pons V2 factory	0x7eD598BcEf8bd9Edd8C97A195C6d13f40801EC7e	primary TokenLaunched path

HARMONIC token / agent vault / LP manager addresses stay off the fixed table until verified on-chain—demo paste fields accept them when known.

2. Event: TokenLaunched → optional Hookr / Initialize

Keep local JSON LAUNCH_FACTORY (multi-address OK) + LAUNCH_TOPIC0 + optional POOL_MANAGER. One RH public WSS: primary Pons V2 TokenLaunched; optional Hookr launchpad + PoolManager Initialize.

Step A · Subscribe Pons V2 TokenLaunched

{
  "jsonrpc": "2.0", "id": 1, "method": "eth_subscribe",
  "params": ["logs", {
    "address": "0x7eD598BcEf8bd9Edd8C97A195C6d13f40801EC7e",
    "topics": ["0x8d4aad4953d0ca700d468f3753aa14432d1b35b43ec6409f051fb6aa43a89607"]
  }]
}

• topics[0]: TokenLaunched(address,address,address,address,uint256,uint256)
• topics[1] = token · topics[2] = curve · topics[3] = deployer
• data: pairToken · launchConfigId · graduationThreshold
• Write launchState[token], tag pons-v2

Step B · Optional: Hookr launchpad logs

{
  "jsonrpc": "2.0", "id": 2, "method": "eth_subscribe",
  "params": ["logs", {
    "address": "0xa043caBE645636899dDe91Cce4693C00a015e660",
    "topics": ["HOOKR_LAUNCH_TOPIC0"]
  }]
}

• HOOKR_LAUNCH_TOPIC0: confirm against Hookr launchpad ABI (editable in demo); generation addresses can rotate—paste the live launchpad.
• Decode token / pool / quote → tag hookr.

Step C · Optional: V4 Initialize (pool-ready layer)

{
  "jsonrpc": "2.0", "id": 3, "method": "eth_subscribe",
  "params": ["logs", {
    "address": "0x8366a39CC670B4001A1121B8F6A443A643e40951",
    "topics": ["0xdd466e674ea557f56295e2d0218a125ea4b4f0f6f3307b95f85e6110838d6438"]
  }]
}

Same-window currency0 / currency1 hitting open launchState → stack pool-ready.

Field	Rule
pad	pons-v2 / pons-v1 / hookr / v4-init
token / curve / deployer	TokenLaunched topics
pairToken / threshold	decoded data
poolId / hooks	Initialize layer (optional)
ready	primary launch event seen

Step D · Open-card fields

{ chain: "robinhood", pad, token, curve, deployer, pairToken, threshold, poolId?, launchTx, blockNumber, ts }

Dedupe on token + launchTx; demo knobs: factory list + topic0.

3. Browser demo (StackBlitz)

Default RH public WSS; Pons V2 factory / TokenLaunched topic prefilled and editable — optional Hookr + PoolManager — hit Start, stream agent-launch cards. Code lives in StackBlitz — the post only embeds the preview:

4. Alert rhythm

1. TokenLaunched arrives → decode token / curve / deployer / pairToken · open the window.
2. Hookr / Initialize (optional) → stack pad / poolId on same token.
3. Outbound → HARMONIC RHC · pad=pons-v2 · token=… · curve=… · deployer=… · launchTx=… · blk=….
4. Dedupe → one push per token + launchTx.

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

5. Summary + CTA

1. Grain: HARMONIC RHC agent open = Pons / Hookr launch-path listen.
2. Recipe: TokenLaunched topic0 + editable venue list → open card; optional Hookr / V4 Initialize.
3. Runnable: browser on BlockReq RH public WSS; demos1 paths above.
4. Start: Public endpoints + blockreq.com register for 3M free requests monthly.

Next: widen the venue table → webhook → stack on-screen with PONS one-pad / any-quote launch. Docs · Pricing · Register.

FAQ

What is 0x7eD598BcEf8bd9Edd8C97A195C6d13f40801EC7e?

It is the Pons V2 factory on Robinhood Chain (chainId = 0x1237, 4663) and the primary path this radar listens to: every new Pons launch emits TokenLaunched from this address. The older Pons V1 factory 0xA5aAb3F0c6EeadF30Ef1D3Eb997108E976351feB can be added as an optional legacy parallel.

What is the Pons TokenLaunched topic0 and what does it decode to?

topic0 = 0x8d4aad4953d0ca700d468f3753aa14432d1b35b43ec6409f051fb6aa43a89607, i.e. TokenLaunched(address,address,address,address,uint256,uint256). topics[1] = token, topics[2] = curve, topics[3] = deployer; data carries pairToken · launchConfigId · graduationThreshold.

How do I watch new Pons launches live?

Send eth_subscribe logs with address = the V2 factory and topics = [TokenLaunched topic0] over the public WSS wss://robinhood-mainnet-rpc.blockreq.com/v1/rpc/public, or open demos1 HARMONIC — factory and topic0 are prefilled and editable, with optional Hookr launchpad and V4 PoolManager Initialize layers.

What happens if the WebSocket drops?

Reconnect and re-subscribe, then gap-fill with HTTPS eth_getLogs on the same factory. Dedupe on token + launchTx so each launch is pushed once.
