RH any-quote launch tool: one-tx pool by quote

pardotfamily / Bonded / Hookdaq-style narratives: the quote leg is editable—stock tokens, stables, or any whitelisted asset can price the pool. This post subscribes RH public WSS to V4 Initialize / Factory PairCreated, then emits one-tx open cards through an editable quote whitelist.

1. Hook: any-quote one-tx pool

Tape feel	On-chain signal	Watch
Any quote leg	currency0 / currency1 / token0 / token1 ∈ quote whitelist	quoteSide + memeSide
One-tx open	V4 Initialize or Factory PairCreated	poolId / pair + fee
Multi-pad same shape	pardotfamily / Bonded / Hookdaq style	editable pad tag
Sniper hear-first	quote hit → outbound	Dedupe = txHash / poolOrPair

Coverage expands to an editable quote table: stack with PONS one-pad, stock-pair meme, and V4 direct-open—this post turns the quote gate into a shared whitelist.

2. Event: Initialize / PairCreated + quote whitelist

Keep POOL_MANAGER / V2_FACTORY / QUOTE_WHITELIST (local JSON, lowercased, deduped) in env. One RH public WSS; both subs can run in parallel.

Step A · Subscribe V4 Initialize

{
  "jsonrpc": "2.0", "id": 1, "method": "eth_subscribe",
  "params": ["logs", {
    "address": "${POOL_MANAGER}",
    "topics": ["0xdd466e674ea557f56295e2d0218a125ea4b4f0f6f3307b95f85e6110838d6438"]
  }]
}

Step B · Subscribe Factory PairCreated (parallel OK)

{
  "jsonrpc": "2.0", "id": 2, "method": "eth_subscribe",
  "params": ["logs", {
    "address": "${V2_FACTORY}",
    "topics": ["0x0d3648bd0f6ba80134a33ba9275ac585d9d315f0ad8355cddefde31afa28d0e9"]
  }]
}

• POOL_MANAGER / V2_FACTORY: fill from the RH deploy table when ready.
• topics[0]: V4 Initialize / V2 PairCreated (confirm against ABI).
• Decode both sides → QUOTE_WHITELIST table-check: either side hits → tag any-quote, mark the other as the launch leg.

Step C · Open-card fields

{ path: "any-quote", quoteSide, launchSide, poolOrPair, fee?, hooks?, factoryTx, blockNumber, ts }

Dedupe on txHash / poolOrPair; demo whitelist is editable (USDG / stock tokens / custom quotes).

3. Browser demo

Connect RH public WSS, paste quote whitelist + PoolManager / Factory, hit Start, stream any-quote open cards.

4. Alert rhythm

1. Initialize / PairCreated arrives → decode both sides + fee / hooks.
2. Quote whitelist hit → label quoteSide / launchSide.
3. Outbound → RH any-quote open · quote=… · launch=… · pool=… · blk=….
4. Dedupe → one push per txHash / poolOrPair.

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