Android app · pump.fun custom pairs

Every custom pair. One feed.

A pump-launched token no longer has to trade against SOL. Custom pairs quote it against QQQx, USDC, PUMP or another memecoin instead — and aggregators that assume SOL quoting mostly index those pools away, so they are easy to miss. CrossPair watches for them and lists the newest mint first.

The basics

What are custom pairs?

On pump.fun, a new token normally trades against SOL. A custom pair is a pump-launched token whose PumpSwap pool quotes against something else — an xStock, a stablecoin, or another memecoin.

A choice of quote currency

A launch can pair against a Nasdaq-tracking xStock (QQQx), a stablecoin (USDC), or another memecoin (PUMP) instead of SOL. The quote stops being plumbing and becomes part of the token's identity — so it needs its own feed.

Hard to find by hand

Aggregators assume SOL quoting, so custom-pair pools are easy to miss unless you dig pool by pool. CrossPair's monitor continuously watches pump.fun's great-coins list, detects pump-minted tokens that acquired a non-SOL quote pair, and serves them to the phone — no manual pool hunting.

How the monitor filters

A token enters the feed only when both rules hold:

  1. its mint address ends with the pump.fun mint suffix pump, and
  2. at least one of its pairs uses a quote token that is not SOL.

Pairs on pump.fun venues (pumpfun, pumpswap) qualify directly. Pairs found on other DEXes are admitted only above a $500 liquidity floor and stay labeled with their venue.

Why newest first

The feed sorts by mint date, not volume. A four-minute-old custom pair with almost no liquidity yet is the entire point of the list — volume-sorted feeds are exactly where brand-new pairs get buried. Newest first, always.

The monitor re-checks every tracked pair on each sweep and refreshes liquidity, price and 24h volume, so freshness is visible rather than implied.

What's in the app

Four tabs and a trade card

Browse first: the feed, boards and search all work signed out. The wallet is only needed when you decide to trade.

Live custom-pair feed

The newest custom-pair tokens first. Each card shows the token, its quote chip ("PAIRED WITH QQQX"), mint age, liquidity, 24h move and volume. Tap any card for detail and trading.

Quote boards

Every custom quote the monitor has seen — QQQx, USDC, SPYx, AAPLx, memecoins — with token count and total liquidity. Open a board to browse its tokens newest-first.

Search with CUSTOM PAIR badges

Look up any Solana token by name, symbol or mint. Results for monitor-tracked mints come back with a custom pair badge and their quote chip, so tracked pairs stand out from ordinary rows.

Non-custodial trading

Token detail pages include quote review and trading: swaps are quoted by Jupiter and approved in your own Solana wallet through Solana Mobile Wallet Adapter, with submitted-signature confirmation. CrossPair never takes custody and never asks for private keys.

Device-local watchlist

Save the pairs you want to keep an eye on. The watchlist lives on your device only — no account, no sign-in, and it survives while the wallet is disconnected.

Monitor status and methodology

The Me tab shows the live monitor state — last sweep, tokens tracked, quote boards tracked, sweep cadence — and the app ships a plain-English methodology screen covering the filter rules, the data sources and the risks.

Real screens

Before you tap buy

What this app is, and what it is not

An unofficial tool

CrossPair is an independent app. It is not affiliated with, endorsed by, or sponsored by pump.fun, Solana Labs, Jupiter or any exchange or issuer named on this page.

Nothing here is financial advice

CrossPair lists and routes; it does not recommend, rate or vouch for any token. SOL and other digital assets are volatile, and you can lose what you put in. Always do your own research.

New pools are experiments

Custom pairs are new. Liquidity can vanish without notice, a custom quote token can be worth far less than SOL, and a young pool can behave in ways nobody has seen before. Trade only what you can afford to lose.
