Paper money only · live Solana prices
Test a trading idea with pretend money, on real prices.
Paperhelm lets you build small rule-following traders called agents. Each one gets $10,000 of paper cash, watches live prices, and writes down every decision with the reason. You see whether it beat simply holding.

How it works in 3 steps
-
1
Pick a rule and some tokens
Choose one of four rule sets, like "buy what is climbing", and a basket of tokens for it to watch.
-
2
It trades with paper cash
About every 20 seconds the page reads live prices. The agent checks its rule and writes a line: buy, sell or wait, and why.
-
3
See if it beat holding
The leaderboard puts each agent next to what you would have made by just buying the same tokens and holding them.
The desk
Your agents, ranked against doing nothing.
Three sample agents are already running. They started seven days ago and were replayed hour by hour from real price candles, so the board is honest from the first second. Everything here is paper money.
"Just holding" = $10,000 split equally across the same basket at the agent's start, never touched. Edge is the gap in percentage points. A 0.3% paper cost is charged on every trade as a model of swap fees and slippage.
Build an agent
Write the rule. Hand it $10,000 that does not exist.
An agent is only its rules. It cannot guess, feel or improvise, which is exactly why it is a fair test of an idea.
- Up to five tokens per basket
- Start from now, or replay the last 7 days first
- Saved in this browser, catches up when you return
Signal bench
What would each rule do with this token right now?
Pick a token. The bench reads its live price and its last hourly candles, then shows the exact number every rule looks at and how close it is to acting. A model, not advice.

Inside one decision
Twenty seconds in the life of an agent.
- 01
The rules are fixed
You set them once: a lookback, a trigger and a stop. The agent never changes them on its own.
- 02
Live prices arrive
The page asks the Jupiter price feed for every token in the basket. No order is sent anywhere.
- 03
The rule is checked and logged
Each token gets a verdict. Buy, sell or wait is written to the log together with the number that caused it.
- 04
It is scored against holding
The paper book is re-valued and placed next to the do-nothing basket. That gap is the only score that matters.
Two maps
Where things go, and where they never go.
What the coin is for
A key to a bigger desk. Not a promise of anything else.
The desk is free for everyone. Holding the coin widens it. There is no yield, no payout and no claim on anything.
More agent slots
Everyone can run 3 of their own agents next to the samples. A connected wallet that holds the coin gets 8. The check is one read of your token accounts.
Holder mark on scorecards
Scorecards you copy or sign carry a small "holder" line, checked on chain at the moment you make them.
Longer replays
Start agents from 30 days of history instead of 7, and keep a deeper decision log per agent.
Votes on the next rule set
Holders sign a message to vote on which rule type gets built next. One wallet, one signed vote, counted in the open.
Holder check
The coin address is not set yet. Once it is, this button reads your wallet's token accounts and unlocks the extra slots on the spot.

FAQ
Plain answers.
What is this, in one sentence?
A practice desk where rule-following agents trade pretend money on real, live Solana prices so you can see how an idea would have done before risking anything.
Is it safe?
The page cannot move funds. It never builds a transaction. Connecting a wallet is optional and only shares your public address; the one thing you can approve is signing a plain text scorecard, and the text is shown first. Everything else is arithmetic in your browser.
Are the trades real?
No. Nothing is bought or sold anywhere. Each "trade" is a line in a notebook stored in your browser, priced at the live feed with a 0.3% paper cost added. Real trading has worse fills, failed swaps and thin liquidity that a notebook does not feel.
Is an agent "AI"?
No. An agent is a short list of fixed rules with numbers you set. The same prices always give the same decision. The page shows the rule and the number behind every line.
How do the sample agents already have a week of history?
When you first open the page it downloads the last days of real hourly price candles and replays the three sample rules through them, hour by hour. Those lines are marked "replay". From then on they decide on live prices, marked "live".
What happens when I close the tab?
Polling stops. When you come back, the page fetches the hourly candles you missed and lets every agent catch up on them, then carries on live. Moves inside an hour that you missed are not seen, and the log says which lines came from candles.
Where is my desk stored?
In this browser's local storage, on this device only. There is no account and no server copy. Use Export to move it or keep a backup; clearing site data deletes it.
If an agent wins here, will it win with real money?
Nobody can know that. A week of paper results is a small sample, and past prices do not repeat on request. Treat the board as a way to understand a rule, not as a forecast.
