CHARTPL-0000Solana mainnet
Check any coin's health, live, like a heart monitor.
For anyone holding or eyeing a Solana coin: type its name, and every real trade shows up as a heartbeat. You also get a plain reading of buyers versus sellers, how easy it is to sell, and how wild the price is.
Beats are real transactions read from the Solana network; readings come from DexScreener. The health labels are our simple model, not advice.

Reading the first beats…
AdmissionHow it works in 3 steps
- 1 · You give
A coin's name or address, or connect your wallet.
- 2 · Pulseline does
Watches every real trade and reads live market data.
- 3 · You get
A live heartbeat and a plain-English health check.
Read-only. Nothing is moved or charged: Pulseline has no button that sends a transaction, and connecting only shares your public address.
Section 2 · Vitals
The full health check
What this does: it grades the coin on the monitor: are people buying or selling, could you sell easily, and how wild is the price.
Buying and selling over four time windows, how much money sits in its liquidity pool compared with its market cap, and how much the price jumps. Each is graded stable, watch or critical. The grades are our model; the numbers are live.
Runs the health check on JUP, the coin of the Jupiter exchange.

Section 3 · Your ward
Check every coin in a wallet
What this does: it gives each coin in a wallet a quick health grade, so you see which ones need attention.
Connect your wallet, or paste any public wallet address. Pulseline reads the list of coins it holds (each sits in a token account), looks each up on DexScreener and sorts them by condition. Press Monitor to watch one live.
Checks a large public wallet. No wallet of yours needed.
No address yet. Read-only: only your public key is used.

Section 4 · Perp funding
Are traders betting up or down?
What this does: it shows, for the biggest crypto markets, whether bettors lean toward prices rising or falling.
On Hyperliquid, people make perp bets. Every hour the popular side pays the other a small fee called funding: green means up-bettors pay, so the crowd leans up. Sorted by open interest. Tap a market for seven days of history.
Opens seven days of funding for SOL.
| Market | Mark | Funding / h | Annualised | Open interest | 24h volume |

Section 5 · Treatment plan
What-if replay: trade profits that buy back a coin
What this does: it replays the last few weeks to show what a bet would have earned, and how much of the coin on the monitor that money could buy back.
Some coin teams hold a price bet and use any profit to buy their own coin (a buyback). Pick the bet, its size and its leverage; Pulseline replays real Hyperliquid prices. It is the past, not a forecast.
A $10,000 bet that SOL rises, 3× leverage, last 14 days.

Section 6 · Alarms
Get an alarm when something changes
What this does: it warns you, while this page is open, when the coin on the monitor crosses a limit you set.
For example: too many sellers, a sudden price jump, or money leaving the pool. Limits are saved in this browser. Sound and desktop notifications are optional.
Sets very tight limits so you see an alarm fire. Change them back after.
How a beat is drawn
From a block to a heartbeat
- ListenEvery 15 seconds Pulseline asks mainnet for the newest signatures on the token's pool.
- PlaceEach signature has a block time. That time becomes a point on the paper.
- ShapeA confirmed transaction draws a full PQRST complex; a failed one draws a small inverted ectopic beat.
- RateBeats in the last minute give the heart rate; long gaps flatten the line.

How we grade a coin's health
What this does: it shows the exact cut-offs behind "stable", "watch" and "critical", so nothing is hidden.
The grades are our model, kept simple and published here so you can disagree with them.
| Vital | Input | Stable | Watch | Critical |
|---|---|---|---|---|
| Heart rate | signatures in last 60 s | 2 – 120 | under 2, or 120 – 400 | 0 for 5 min (flatline) |
| Pressure | sells ÷ (buys + sells), 1h | under 55% | 55 – 70% | over 70% |
| SpO₂ | liquidity ÷ market cap | over 8% | 3 – 8% | under 3% |
| Temperature | σ/h from 5m, 1h, 6h, 24h moves | under 4% | 4 – 10% | over 10% |
| Respiration | 24h volume ÷ liquidity | 0.2 – 5× | under 0.2 or 5 – 15× | over 15× |
Glossary
Words explained
What this does: it explains, in plain words, the trading terms used on this page.
- Coin address (mint, CA)
- A coin's unique ID on Solana, a long string of letters and numbers. "CA" means contract address.
- Pool
- The pot where a coin is traded against SOL or dollars. Each trade happens in a pool.
- Transaction, signature
- One action recorded on Solana, like a trade. Each has a unique ID called its signature. One beat = one transaction.
- Failed transaction
- A trade that was tried but did not go through (often bots racing). Drawn as a small upside-down beat.
- Liquidity
- The money waiting in a coin's pool. More liquidity means big trades move the price less.
- Market cap, FDV
- Price × number of coins: what the whole supply is worth today. FDV counts coins not released yet too.
- Volatility (σ)
- How much the price typically jumps in an hour. Shown as the coin's "temperature".
- Wallet address
- Like a public account number. Anyone can look it up; only the owner can move anything.
- Token account
- The little box inside a wallet that holds one kind of coin.
- Perp, long, short
- A bet on price without owning the coin. Long = betting up, short = betting down.
- Funding
- An hourly fee between perp bettors. Positive means up-bettors pay down-bettors.
- Open interest
- The total size of all open perp bets on a market.
- Leverage, liquidation
- Leverage multiplies a bet with borrowed money. If losses eat the deposit, the bet is closed: liquidated.
- Buyback
- A project using money to buy its own coin from the market.
- Price impact (x·y=k)
- How much a purchase would push the price up, using the standard pool formula. An estimate.
- Mainnet
- The real, live Solana network (not a test copy).
Section 8 · Questions
Asked at the nurses' station
What is this, in one sentence?
Pulseline is a free, read-only page that shows any Solana coin's trading as a live heartbeat and tells you in plain words whether it looks stable, worth watching or risky.
Is it safe? Does it touch my money?
It never touches your money. Pulseline only reads public data and has no button that sends a transaction. Connecting a wallet just shares your public address so it can list your coins. It never asks for your secret recovery phrase. The health grades are a simple model and not financial advice.
Is the trace real or decorative?
Real. Each complex sits at the block time of an actual signature on the token's main pool, read through this site's read-only Solana RPC proxy. When the pool is quiet the line goes flat, because nothing happened.
Why do some beats look different?
Transactions that failed on chain (slippage, expired quotes, bots racing) are drawn as small inverted beats. They are part of the pool's activity, but they moved nothing.
Where do buys and sells come from?
From DexScreener's public pair data, which counts buys and sells in 5-minute, 1-hour, 6-hour and 24-hour windows. Pulseline does not decode each swap; the trace shows timing, the vitals show direction.
Is the buyback simulation a strategy?
No. It replays past Hyperliquid prices and funding to show how a perp-backed buyback would have behaved. It ignores fees and margin rules, and the past is not a forecast. Nothing here is financial advice.
Does Pulseline ever trade or send anything?
No. It only reads public data. Connecting a wallet shares your public key so the ward can list your holdings; there is no transaction anywhere on this site.
How often does it check for new data?
Signatures every 15 seconds and DexScreener every 30 seconds, only while the monitor is on screen and the tab is visible. Hyperliquid funding every 30 seconds while the feed is visible.
