Pump Custom Pair open tool: quote whitelist

Pumpfun Custom Pairs widen the quote leg to tokenized stocks / majors / metals: creators pick an xStocks, Sunrise, or similar quote mint at create time, with bonding-curve and PumpSwap fees matching standard opens. This post pre-wires the Create / CustomPair + quote-mint whitelist recipe—browser keeps SOLANA_HTTPS / SOLANA_WSS placeholders; once the node is ready, fill the endpoint into env and run.

Run on the public endpoint · blockreq.com register for 3M free requests monthly.

Use	Endpoint (placeholder)
HTTPS	process.env.SOLANA_HTTPS (fill when the node is ready)
WSS	process.env.SOLANA_WSS (fill when the node is ready)
Private	Trailing public → {API_KEY} (keys stay local)

Chain: Solana. Recipe: logsSubscribe (mentions Pump program) → decode Create/CustomPair → quote mint ∈ whitelist → open card. Browser demo ships UI + sample rows first; swap the real endpoint when ready and keep listening. Public endpoints · Plans · Register.

Stack separately from RH stock-pair launches: this line is Solana Pump Create/CustomPair + quote-mint whitelist; the RH line is EVM Factory PairCreated (see stock-pair meme · RH any-quote).

1. Hook: hear Custom Pair opens by quote

Tape feel	On-chain signal	Watch
Quote-whitelist open	Create / CustomPair with quote mint ∈ table	baseMint / quoteMint
xStocks / majors leg	quote = NVDA* / TSLA* / BTC* …	whitelist tag + mint
Sniper hear-first	quote hit → outbound	Dedupe = signature / mint
Endpoint swap	env swap → keep listening	fill SOLANA_WSS and run

Feel: standard Pump open = Create; Custom Pair adds a quote-mint gate—only whitelist quote legs become cards.

2. Event: logsSubscribe + quote whitelist

Keep SOLANA_HTTPS / SOLANA_WSS / PUMP_PROGRAM / QUOTE_WHITELIST in env. When the node is ready, change the endpoint only—the subscribe body and filter stay the same.

Step A · Subscribe Pump program logs

{
  "jsonrpc": "2.0", "id": 1, "method": "logsSubscribe",
  "params": [
    { "mentions": ["PUMP_PROGRAM"] },
    { "commitment": "confirmed" }
  ]
}

• mentions[0] = process.env.PUMP_PROGRAM (official program-id table).
• Client-scan logs for Create / CustomPair / equivalent create instruction names.
• HTTPS getTransaction (encoding: "jsonParsed") pulls baseMint / quoteMint / bonding curve.

Step B · Quote-mint whitelist filter

QUOTE_WHITELIST = editable mint set (xStocks / Sunrise / majors …)
hit = quoteMint ∈ QUOTE_WHITELIST  →  write launchState

Open-card fields:

{ pad: "pump-custom-pair", baseMint, quoteMint, quoteTag, signature, slot, ts }

Dedupe on signature / baseMint; merge repeat pushes for the same mint inside a short window.

Step C · Optional stack: PumpSwap graduation

After Create, scan the same program / PumpSwap path for migrate / graduate logs; graduation signature → stack graduated / pumpSwapPool chip.

3. Browser demo

Connect the SOLANA_WSS placeholder, fill Pump program + QUOTE_WHITELIST, hit Start: UI streams sample open rows first; once the node is ready, swap the real endpoint and the same filter keeps listening.

4. Alert rhythm

1. Create / CustomPair arrives → parse baseMint / quoteMint.
2. Whitelist hit → outbound Pump Custom Pair · base=… · quote=… · tag=… · slot=….
3. Optional → PumpSwap graduation as a second chip.
4. Dedupe → one push per signature / baseMint.

On disconnect: reconnect and re-logsSubscribe; gap-fill with HTTPS getSignaturesForAddress + getTransaction on the same program. POST → process.env.SOLANA_HTTPS.

5. Summary + CTA

1. Grain: Custom Pair open = Create/CustomPair + quote mint ∈ whitelist.
2. Recipe: SOLANA_WSS + PUMP_PROGRAM + QUOTE_WHITELIST + optional PumpSwap graduation → open card.
3. Runnable: browser pre-wired with placeholders + sample rows; once the node is ready, fill the endpoint into env and run.
4. Start: Public endpoints + blockreq.com register for 3M free requests monthly.
