PaperTrench overlays a paper-trading terminal on the memecoin sites you already use — real charts, real live prices, fake money — then shows you exactly what you did and why. Learn in an afternoon what usually costs a wallet.
Every paper buy and sell renders as a bubble at the exact price level of the fill — the same visual treatment real trades get. On Padre, fills go one step further and render as native TradingView markers with average entry and exit lines.
Bubbles sit at the actual fill price and time. Hover any bubble to see price and SOL amount.
Buys and sells appear as real TradingView markers, with average fill and exit lines drawn on the series.
Click buy before a brand-new coin even has a quote — the order arms, then fills the instant the first trusted price lands.
Hit record and PaperTrench captures your screen while you trade. Afterwards, scrub through the whole session on one timeline — every fill, every chart frame, and the recording itself, perfectly in sync. Watch yourself chase. Then stop.
Screen recording built into the extension — no OBS, no setup. Recordings are stored locally in IndexedDB.
Every buy and sell is a marker on the scrubber. Jump straight to the moment you pulled the trigger.
Recordings live in your browser and save to your downloads folder. Nothing is uploaded, ever.
While the position is open, you write down why you took the trade, tag the setup, and set a target and stop. When the round closes, PaperTrench grades your process — not just your P&L — because anyone can get lucky once.
Your reasoning is on record before the outcome exists. No revisionist history.
Win rate and average P&L per setup tag — so revenge gets compared honestly against narrative.
Every round graded excellent / sold early / round-tripped — with the SOL you left on the table quantified, and positions over 25% of your book flagged.
Point it at any OpenAI-compatible endpoint and get a review of a round — judged against the plan you wrote.
Every fill is committed to a SHA-256 hash chain the moment it happens — before the outcome is known. No inserting trades, no deleting losers, no backdating winners. The dashboard re-derives your record from the chain and standings are recomputed server-side from the raw fills, never from a self-reported number.
Each fill commits to the hash of the previous one. Touch anything, and every link after it breaks.
Fills record mint, price, and timestamp — so a verifier can re-check them against real market history.
One ranked record per verified account, making sybil entries expensive.
The overlay, the positions bar, and your fills — living directly on the chart you're already watching.
Every fill is validated against a trusted anchor from Dexscreener and Jupiter, raced in parallel. No source, no number — the panel says so instead of guessing.
Jupiter is queried in parallel with Dexscreener, so a coin that just hit the curve is tradeable before indexers even see it.
Every open position pinned to the top of the page with live P&L. Click one to jump straight to its chart.
Turn any closed round into a 1200×675 image with your own picture or GIF behind it — permanently watermarked PAPER, so it can never pass as a real trade.
The decision logic is pure functions exercised directly by the suite — the same code that runs in the page — and each guard has to fail against the exact change it protects against.
No account, no signup, nothing phoned home. The only network calls are the public price APIs — and your own AI endpoint, only if you configure one.
Streamers grind the leaderboard on stream, with giveaways for the best verified records — and a built-in OBS overlay so you can stream your own runs.
Not on the Chrome Web Store yet — loading it unpacked is quick.
Go to chrome://extensions and flip on Developer mode.
Select the folder containing manifest.json.
Open any supported token page — the overlay appears within seconds.
Updating later? Unzip the new release over the same folder you already loaded (overwrite the files), then hit ↻ Reload on the extension card. Your wallet, history, and attest chain all live with the folder — a brand-new folder starts a blank wallet. You can also back up from the extension popup any time.
The usual way people learn this market is losing money finding out they chase, oversize, and round-trip their winners. PaperTrench tells you that in an afternoon instead.
