Seven real costs, not one
Network fee, priority fee, Jito tip, token-account rent, platform fee, LP fee and BNB transfer tax — all charged from your balance. Most simulators charge none of them.

Paper trade memecoins.
Real prices. Fake money.
Ghostbag sits on top of the terminal you already use and lets you buy and sell the coin on screen at its live price — with money that isn’t yours. Real fees, real price impact, fake money, on Solana, BNB Chain and Robinhood Chain. It never connects a wallet, never asks for a key, and never signs anything.
The most advanced memecoin paper trading software in the world — free, with no account and no wallet. Here is what backs that.
Ghostbag is a paper-trading browser extension. It is not a cryptocurrency, token, exchange, wallet or launchpad, and it is not affiliated with Bags.fm or any token named GHOST.
Watch Ghostbag in action.
Live on the terminal
One click is the order.
Ghostbag stays beside the chart instead of replacing it. Choose a SOL size to buy immediately, sell a percentage with one click, and keep the position tape visible in SOL or USD.
Quick Buy
Set your paper-trade size once, then place the trade from the coin row. Ghostbag adds a compact Quick Buy control to supported trench views, so you can practise entries across New Pairs, Final Stretch and Migrated without opening every chart first.
Each click submits the selected virtual SOL, BNB or ETH amount against verified live market data. The control stays attached to its coin while you scroll, and Ghostbag skips a row when it cannot identify the correct contract safely.
Live P&L overlay
Watch your P&L live, on every page.
A compact tracker follows your paper wallet across every supported terminal, keeping balance, live P&L and the equity curve in view while you trade. The immediate feedback makes each entry and exit feel more immersive without taking over the market.
- Updates as the active coin price changes
- Drag it anywhere and resize the card in settings
- Show or hide the live equity curve at any time
On-chart markers
See your trades on the chart.
Every paper fill is pinned to the chart you are already reading. Buy entries and sell exits sit where they happened, and a dashed average buy and average sell line run the width of the chart — so you can see the whole position at a glance instead of reconstructing it from a list.
- Buy entries
- Sell exits
- Avg Buy
- Avg Sell
Markers are anchored at the market cap recorded when the paper order settled, so panning or zooming the terminal never drags a fill somewhere it did not happen.
Inside Ghostbag
The whole account stays one click away.
Open the compact account view without leaving the terminal. Move between positions, trades and the calendar, then jump into the full dashboard when you need the wider record.
History and calendar
Find the sessions that shaped the month.
Switch between the fill history and calendar inside the extension. Daily realized results, win rate, trade count and monthly return stay tied to the active paper wallet.
Account popup
Read the whole paper wallet from the terminal.
Balance, today’s result, cash, open positions and recent fills stay together. Open the dashboard, change the display currency or export without breaking your terminal flow.

Settings panel
Set the panel up around your flow.
Order rules, Quick Buy, the live tracker, type, sound and wallet controls live in one scrollable panel. Swipe through the current screens below.
Order rules
Tune both sides of the paper trade.
Set buy and sell priority fees, tips and slippage separately, then keep up to eight buy amounts and sell percentages in the order you use them.
Quick Buy and execution
Choose what appears beside every token.
Control Quick Buy, order size and the live P&L card, then keep immediate paper fills or deliberately add delay and simulated failures for practice.
Appearance and wallet
Make the surface readable at trading speed.
Scale the panel, choose a bundled typeface and fill sound, adjust volume, select the active paper wallet and start a fresh run from one screen.

Share cards
Share a recorded result, not a vague claim.
Turn the active paper wallet’s monthly ledger into a clean result card, keep the paper-trading label visible, and use a background that feels like yours. Choose a card below or swipe through the stack.

Ghostbag dashboard
Your paper desk, at a glance.
The extension handles the moment-to-moment trade. The dashboard gives you the wider view: equity, open positions, completed trades, calendar performance and the controls that shape your next run.
Overview
See the run, not just the last click.
Account equity, total PnL, active positions, the equity curve and the latest executions share one calm workspace.
Positions
Know what is still open.
Review cost, live market cap and unrealized performance for the active paper wallet.
Trades
Filter the ledger quickly.
Search by symbol, narrow by chain or run, and keep the full execution record close.
Insights
Measure the habits behind the result.
Compare fill rate, impact, fees and holding time with the sample sizes and recorded results visible beside every figure.
Calendar
Spot the pattern in your month.
Daily realized PnL turns a pile of fills into a performance rhythm you can actually review.
Terminal controls
Place the controls where the terminal needs them.
Adjust Quick Buy size and position, paper order size, live P&L visibility and overlay scale from the dashboard.
Appearance
Keep the information readable in your setup.
Choose the typeface and text colour, set the button surface, and scale the trading panel and P&L tracker independently.
Background framing
Frame one image for two different surfaces.
Set strength and blur once, then crop the tall trading panel and wide P&L tracker independently so both stay legible.

Why we say it
The most advanced memecoin paper trading software in the world — and it is free.
That is a large claim, so here is what it rests on. Every item below is something Ghostbag does today, on your machine, at no cost and with no account.
Constant product on real reserves
Price impact computed against the pool's actual depth, not a flat percentage and not ignored. A big order into a thin pool fills badly, exactly as it would on-chain.
Latency, reverts and slippage
Orders take time to land, can revert when you underpay priority, and can be rejected on slippage — and the fees are gone either way. Almost nothing else models failure at all.
17 terminals, 3 chains
Solana, BNB Chain and Robinhood Chain, each with its own gas model and venue fees, on top of the terminals you already use rather than inside a website you have to visit.
Live from the first block
A direct WebSocket feed carrying real bonding-curve reserves, so a brand-new pump.fun coin is priced and tradeable before REST aggregators have indexed it.
No account, no wallet, no tracking
No sign-up, no paid tier, no telemetry and no wallet connection. There is no upsell because there is no business model attached to your data.
Judge it yourself. The comparison table lists what decides whether a trade made money, and what a typical simulator does about each one. If you find a simulator that models more of it, tell us — we would genuinely like to know.
Looking real is not enough.
A trading simulator has to react. Ghostbag follows the coin on screen, records the market cap at the click, applies your execution settings and moves the paper position with the live market.
The price moves. The click lands. The fees count. The fill stays in your history.
Practise before real money is involved. Ignore liquidity, fees or the exit and you can become someone else’s exit liquidity.
How it works
Four steps.
Install it
Add the extension to Chrome. No account, no email, no wallet connection.
Open any coin
Go to a supported terminal and open a token. The panel names it and starts pricing it.
Click a size
Presets execute on one click. Set your own, up to eight a side, in SOL or as a percentage.
Read the tape
Invested, sold, remaining and PnL update live, with entry and current market cap below.
Why choose Ghostbag
Better numbers, or it isn't practice.
A simulator that hands your money back on a flat round trip has taught you that trading is free. Everything you then "learn" from it is inflated. These are the differences that change what you take away.
Real fees, every one of them
Network fee, priority fee, Jito tip, token-account rent, your terminal's platform fee, the pool's LP fee and BNB transfer tax — all charged to the paper balance, per site and per venue.
Real price impact
Constant product against the pool's actual reserves. One SOL into a $3,000 pool hurts exactly as much as it would on chain, and you see it before you commit.
Three chains, priced properly
Solana with a direct pump.fun feed that prices a launch from its first on-chain trade. BNB Chain with live gas. Robinhood Chain through WETH-quoted pools where depth is exact, not estimated.
Evidence, not vibes
Every fill keeps its contract, market cap, impact and result. Win rate, average hold time, a daily PnL calendar and CSV export — all computed from your own ledger.
Privacy
We track nothing. Zero. It's all on your machine.
No account. No email. No analytics, no telemetry, no remote config, no external scripts, no cookies. Your paper wallets, positions and entire trade history are written to your own browser and never leave it — there is no server to send them to.
What stays with you
Wallets, positions, every trade you have ever made, your settings and your panel layout. Delete the extension and all of it goes with it.
What we can see
Nothing. The only requests made are read-only public price lookups for the token on your screen, carrying no identifier of any kind.
Common questions
Asked and answered.
Is Ghostbag free?
Yes. It is free, there is no account, nothing to subscribe to and no paid tier. There is no upsell because there is no business model attached to your data.
Do I need to connect a wallet?
No. Ghostbag never requests wallet permissions and never touches window.solana or window.ethereum. There are no keys, no seed phrases and nothing is ever signed. The money is paper.
Which chains does it support?
Solana, BNB Chain and Robinhood Chain — with the correct native coin, gas model, venue fees and pool depth on each.
Which sites does it work on?
pump.fun, Axiom, Padre, Photon, BullX, GMGN, DexScreener, four.meme, Trojan, Fomo, Telemetry, Jupiter, Azura, Definitive, Shotgun, Solpump and Cielo. Multi-chain terminals trade only on the networks Ghostbag can price correctly: Solana, BNB Chain and Robinhood Chain.
Is Ghostbag a crypto token or part of Bags.fm?
No. Ghostbag is an independent browser extension for simulated memecoin trading. It does not issue a token, launch coins, custody funds or connect to a real wallet, and it is not affiliated with Bags.fm.
How accurate is the simulation?
It models network fees, priority fees, Jito tips, token-account rent, platform and LP fees, BNB transfer taxes, constant-product price impact, latency, slippage rejection and reverts, using integer base units throughout. It is a simulation, not a promise — but it will never tell you a flat round trip was free.
Do I need an account, an email or a wallet?
None of the three. Install it, open a coin on a terminal you already use, and click a size. Nothing to sign up for, nothing to verify, nothing to connect.
Why does a round trip lose money if the price did not move?
Because that is what it costs on-chain. You pay a platform fee and an LP fee going in and again coming out, plus network fee, priority fee, tip and — on a first buy — token-account rent. On a 1% platform and 1% LP pool the break-even is about 1.042x, so a coin that rises 3% is still a losing trade.
Can I turn the random failures off?
They are already off. Valid paper orders fill deterministically unless you switch on the execution simulator in advanced settings, which is there for rehearsing a bad fill rather than surprising a first-time user.
Which browsers does it work in?
Chrome and Chromium browsers on desktop — Chrome, Edge, Brave, Arc and Opera — from Chrome 116. The terminals it attaches to are desktop web apps, so there is no mobile build.
Does my trading data leave my machine?
No. There is no analytics and no telemetry, and no server holds your history. The privacy policy spells out exactly what is stored and what is requested.
