Validate before you risk
Test an idea against live prices for days before deciding whether it deserves real capital. A failed thesis costs nothing.
Your thesis, traded in the shadows.
Write one sentence. An AI agent turns it into rules and trades it on live Solana prices, around the clock, with every move on the public record. Prove the idea before you risk a cent.

The Contact Sheet
Every bag below is trading pretend money on real prices right now. PnL comes from the engine record and cannot be edited.
The process
How it works
- 1
Write the thesis
One sentence, in your own words. Include what to buy, how much, and when to exit.
- 2
Read the rules
An AI turns it into plain rules. Edit any number, or ask for a change in words.
- 3
It trades in the shadows
Pretend money, real Solana prices and real Jupiter quotes, checked every minute.
- 4
Share the proof
Every trade is recorded. After one hour you can publish the bag and share its link.
Use cases
What people use shadow bags for
SHADOWBAG is a proving ground. It never touches funds, so you can be as experimental as you like.
Compare strategies side by side
Run several bags with different exits or filters at the same time and see which rule set actually behaves differently.
Learn how slippage bites
Every fill uses a real Jupiter quote with its price impact, so thin liquidity shows up in the result instead of hiding behind a chart.
Publish an honest track record
Creators and communities can share a bag whose record is engine-written and public, rather than a hand-picked screenshot.
Stress-test discipline
Rules do not get emotional. Watch how a plain stop and take profit perform through a full day and night.
Teach and explore
A safe way to show newcomers how screening, sizing and exits fit together, with zero wallet and zero deposit.
How to use
Writing a thesis that trades well
The engine is deterministic. It only does what the rules say, so the clearer the sentence, the more meaningful the result.
Buy trending tokens with 300+ holders when 1h buys are at least 2x sells. Take profit at +40%, stop at -20%, 5% of the bag each.
An example of the sentence format, not a recommendation.
- 01
Be specific about the universe
Say where candidates come from: trending in the last hour, trending over six hours, newly created, top organic score, or a search term.
- 02
State your entry conditions
Use measurable fields such as holders, liquidity, market cap, token age, organic score, price change, volume and the buy to sell ratio.
- 03
Decide your size
Give a percentage of the bag or a fixed amount of SOL, and how many positions may be open at once.
- 04
Define every exit
Take profit, stop loss, trailing stop and a maximum holding time. Anything you leave out is listed as a default before you start.
- 05
Let it run, then judge it
A bag needs time. Look at win rate, drawdown and average hold on the bag page, not a single trade.
- 06
Fork and improve
Found a bag you like? Fork it to copy the rules into a new bag with a fresh start time and balance.
Under the hood
Simulated, but not made up
Nothing on this site is a backtest or a mock-up. Here is exactly what is real and what is pretend.
- Real prices
- Token, price and quote data come from Jupiter public APIs.
- Real price impact
- Entries and exits use live swap quotes for the full position size.
- Modelled fees
- A network and priority fee is deducted from every simulated trade.
- Quote only
- No transaction is ever built, signed or sent. There is no wallet.
- Every minute
- A scheduled engine checks exits first, then new entries, around the clock.
- Engine-written record
- Trades, equity points and stats are recorded by code and cannot be edited.
Real trading can differ from these results because of slippage, MEV, latency and fees.
Why shadow first
Prove it before you risk it
You can test an idea on live prices without risking funds.
Quotes include real price impact, so thin liquidity shows up in the result.
A one hour minimum before publishing keeps public records free of cherry-picked moments.
Questions
FAQ
Does SHADOWBAG trade real money?
No, never. Every trade is simulated with pretend money.
Do I need a wallet or an account?
No. There is no wallet connection, signing or deposit. Your bags are remembered in this browser.
Where do the prices come from?
Public Jupiter token, price and quote data. Fills use real quotes, including price impact, minus an assumed per-trade fee.
How often does a bag trade?
Public bags are checked by a one-minute scheduled engine. Your own bag is also refreshed whenever its page is open.
Why can a bag be published only after an hour?
It stops cherry-picking. Results always come from the engine record and cannot be edited.
Is the AI making trading decisions?
No. The AI only translates your sentence into rules and, optionally, describes a finished record. All trading is deterministic code following your rules.
