Overview
Caster is your agent that watches your coins and speaks up only when something actually happens.
You favourite a coin on Dexscreener, then twenty more, and it gets buried. Caster keeps an eye on the ones you point it at. It watches every trade, reads the chart the way a trader would, and tells you out loud when it matters: a breakout, a curl off the bottom, volume coming in, a whale, the dev selling.
It never tells you what to do. It tells you what happened — so you look at the chart when it matters, not every second of the day.
START
Quickstart
- Open the app and turn your sound on.
- Paste a coin address — any Solana coin: pump.fun, PumpSwap, Raydium, Meteora.
- Pick a mode. Balanced is the default. Quiet if you're watching several coins.
- Get on with your day. Caster tells you what it sees in one sentence, then stays quiet until something happens.

Modes
You decide how much Caster talks. Switch any time — it applies to every coin you're watching.
| QUIET | BALANCED | ACTIVE |
|---|
| Breakouts and breakdowns | ✓ | ✓ | ✓ |
| Setups and curls | ✓ | ✓ | ✓ |
| Volume coming in | ✓ | ✓ | ✓ |
| Whales and the dev | ✓ | ✓ | ✓ |
| Fast moves in one minute | 10% · 6% over $1M | 8% · 5% over $1M | 5% · 4% over $1M |
| Tests of the last high | — | ✓ | ✓ |
| Check-ins | — | Every 5 min, if it moved 5%+ | Every 2 min |
| Buyers or sellers taking over | — | — | ✓ |
No mode reads out every trade. A $600 buy on a $700K coin isn't news, so Caster doesn't say it.

What it tells you
| ALERT | WHEN | EXAMPLE |
|---|
| Setup | Dumped 25%+ and holding a tight range on low volume. | "Building a base after a 33% dump. If volume comes in it could curl — I'll tell you the moment it does." |
| Volume | The last two minutes trade 2.5× the usual and the price is up. | "Volume's coming in — up 7% in two minutes." |
| Curling | 25%+ off the top, now 10%+ off the low, four higher lows in a row. | "Curling off the bottom — down 30% from the top, now up 14% off the low." |
| Breakout | Clears the high of its last hour. | "Breaking out — a new one-hour high at 712K." |
| Breakdown | Falls under the low of its last hour. | "Breaking down — under its one-hour low." |
| Resistance | Back within 3% of the hour's high after being 8%+ below it. | "Back at its one-hour high — that's where it turned last time." |
| Fast move | A big move inside one minute (see Modes). | "Moving fast — up 9% in the last minute." |
| Whale | A wallet buys, holds or sells 1%+ of the supply. | "A whale steps in — one wallet now holds 1.6% of the supply." |
| The dev | The wallet that made the coin sells 0.1%+ of the supply. | "The dev is selling — 0.8% of the supply." |
| Milestone | The market cap crosses a round number on the way up. | "It just crossed 1 million." |
USING CASTER
Watching several coins
Caster watches several coins at once. There is one voice and it never talks over itself: alerts wait their turn, each one starts with the coin's name, and if too much happens at once Caster keeps the newest and drops what's stale.
Quiet mode was made for this: several coins, only the moments that matter.
HOW IT WORKS
How it reads the chart
When you add a coin, Caster gives you one sentence — not a list of numbers. The numbers are already on your screen; Caster tells you what they mean:
"Tiktok Coin dumped 33% and it's holding here. If volume comes in it could curl — I'll tell you the moment it does."
It looks at the last hour: the high, the low, how far it dropped from the top, how tight the last ten minutes are, and how the last two minutes of volume compare with the fifteen before. No indicators, no predictions. Under $100M everything is a memecoin, so Caster keeps it simple and says it in plain words.
What counts as a whale
A wallet that holds 1% of the supply or more. Never a dollar size — $600 is a whale on a $20K coin and a shrimp on a $700K one.
HOW IT WORKS
The numbers
- Trades — every buy and sell on pump.fun and PumpSwap, about a second after it lands. Other DEXs use Dexscreener's live price.
- Market cap — the live price × the coin's real supply. Burned tokens are left out, so the market cap is never inflated.
- The last hour — one-minute candles from GeckoTerminal, refreshed every 20 seconds.
- The dev — the wallet that created the coin on pump.fun.
- The voice — Fish Audio. Exciting moments sound excited, bad news sounds serious. Mute it and keep reading the alerts.
Caster runs in your browser. Nothing you watch is stored on a server.
