Installation

FlipTrainer is a Chrome Extension (Manifest V3). It takes under a minute to install and requires a Google account to sign in.

Requirements

• Google Chrome (version 88 or later) or any Chromium-based browser
• A Google account for sign-in
• An active internet connection

Installation Steps

First Steps

After signing in for the first time, your account is automatically set up with a starting balance and a Solana wallet.

What happens on first login

When you sign in with Google for the first time, FlipTrainer automatically:

• Creates your account with a starting balance of 10 vSOL (virtual SOL)
• Generates a real Solana wallet (Ed25519 keypair) directly in your browser
• Encrypts the wallet key and stores it only on your device — the server only ever receives your public address
• Activates the free Basic plan (Gives you feature for snipe token creation)

Navigating the extension

FlipTrainer opens as a side panel in Chrome. Use the tabs at the top to navigate between pages:

How Trading Works

FlipTrainer mirrors real trading mechanics. Prices come from Solana on-chain data — you're trading against reality, just without real money.

Price Data

Token prices are streamed in real time straight from a Solana validator over gRPC (Yellowstone / Geyser). FlipTrainer decodes Pump.fun and Pump AMM activity on the backend and prices every token from its on-chain bonding-curve / pool reserves — accurate, up-to-the-second, with no polling.

When you open a position, the entry price is locked in at that exact moment. When you close it, the exit price is fetched fresh from the chain.

P&L Calculation

Your profit and loss is calculated as:

P&L = (exitPrice − entryPrice) × positionSize − commission

All financial math uses high-precision decimal arithmetic internally — no floating-point rounding errors affecting your results.

Real-time Updates

While you have an open position, the extension receives live price updates via Server-Sent Events (SSE). Your unrealized P&L updates automatically as the market moves — no manual refresh needed.

Price Impact (Slippage)

Real fills aren't free of slippage, so neither are ours. Simulated trades don't execute at the spot price — they fill at a slippage-adjusted average based on the token pool's liquidity. A buy pushes the price up as it fills, a sell pushes it down, and the thinner the pool, the bigger the move. That means a huge order on a low-liquidity token can't print impossible profit — exactly like the real curve. On deep liquidity the impact is negligible and you fill close to spot.

Opening Positions

Find a token, set your size, and open a position in seconds. The entry price is captured from the blockchain at the moment you confirm.

Steps

Closing Positions

Close a position at any time to realize your profit or cut a loss. The final P&L is calculated using the live on-chain price at the moment you close.

How to close

Your open positions are listed on the Trade tab. FlipTrainer fetches the current price and calculates your net P&L the moment you close. You have a few ways to do it:

• Close one position — click "Close" on any individual position to close just that one.
• Close everything — use the "Close all" button to exit every open position at once.
• Partial close — sell a percentage (10% / 50% / 90% / 100%) to take profit or trim risk while keeping the rest of the position open.

After closing

• Your simulated balance is updated with the proceeds
• The trade moves to your History tab with full entry/exit details

Commission

An effective 2.15% commission is charged on both sides of every trade to mirror real costs: Pump.fun's 1.25% trading fee plus the ~0.9% average terminal fee (Axiom, Padre, GMGN).

How it works

The 2.15% commission is deducted from your position when you open and again when you close. This mirrors how real memcoin trading works — you pay the launchpad fee and your terminal's fee on both entry and exit.

Example

Open position:   10.000 SOL
Open commission: -0.215 SOL  (2.15%)
Effective entry: 9.785 SOL

Token price +20%
Close value:     11.742 SOL
Close commission:-0.252 SOL  (2.15%)
Net received:    11.490 SOL

Net P&L:         +1.490 SOL  (+14.90%)

What is Sniper?

Sniper monitors Solana wallets in real time. Add any wallet address and get instant alerts when it creates, buys, or sells tokens.

How it works

Sniper consumes the same real-time gRPC stream the rest of FlipTrainer runs on. When a wallet you're watching submits a transaction, FlipTrainer decodes it on the backend and instantly opens a browser tab to the token page on your chosen terminal.

This lets you react before the broader market has time to respond.

Use cases

Adding Wallets

A snipe wallet is any Solana address you want to monitor. Each wallet has its own independent event and action configuration.

Steps

Event Types

Event types define which on-chain actions trigger your alerts. You can enable multiple event types per watched wallet.

Detection method

FlipTrainer uses two decoding strategies for incoming Solana transactions:

• IDL log decoding — primary method, parses structured program logs from the Pump.fun and Pump AMM IDLs
• Account-key decoding — fallback, infers event type from the transaction's account layout when logs are absent

Actions

An action is what FlipTrainer does when an event fires on a watched wallet.

Open Browser Tab

Automatically opens a new browser tab to the token's page on your chosen terminal the moment the event fires. One terminal is active at a time — pick the one you trade on.

Tier Limits

The number of wallets you can actively monitor depends on your subscription tier.

Copy Trading & Filters

Copy trading turns a watched wallet into an auto-pilot for your simulated portfolio — when it trades, FlipTrainer trades the same token for you. Available on the Epic plan.

How it works

Pick the events you want to mirror on a watched wallet. When one fires, FlipTrainer opens or closes a position for you automatically through your selected terminal — a Buy is copied as a buy, a Sell as a sell. It's the same flow as a manual trade, just executed the instant the wallet moves.

Position sizing

You choose how big each copied buy is:

• Manual — every copy uses a fixed size you set (in SOL), no matter what the wallet spent.
• Mirror — match the wallet 1:1, copying the same SOL size it traded.

Proportional exits

Sells are copied by proportion, not by amount. If the watched wallet dumps 50% of its bag, FlipTrainer sells 50% of your position; a full exit closes your position completely. So you ride the same way in and the same way out.

Filters

Filters keep the noise out — set them per event type, and they apply independently to alerts and to copy trades. A trade only fires if it passes every filter you've set.

Plans

FlipTrainer has three subscription tiers. Basic is free forever. Rare and Epic unlock the Sniper's full capabilities.

Paying with SOL

Plan prices are set in US dollars, but you pay on-chain in real SOL — the equivalent amount at the current exchange rate — from your built-in FlipTrainer wallet. No credit cards, no third-party processors, just a Solana transaction.

Payment flow

What gets verified

• Sender address matches your account's wallet
• Recipient is the FlipTrainer treasury wallet
• Transferred amount matches the price quoted at purchase confirmation
• Transaction is finalized on-chain

Renewal

Every subscription is a one-time purchase that simply expires on its own. There is no auto-renewal — your wallet is self-custodial, so the server can never charge it without you.

Why there's no auto-charge

Your private key lives only on your device — FlipTrainer's servers can't sign transactions on your behalf. That means we can't silently bill your wallet, and you stay in full control of every payment. The trade-off is that renewal is a deliberate action you take, not an automatic one.

Extending your plan

As your subscription nears its end, FlipTrainer sends you a reminder — a browser push notification and an in-extension alert. In the Shop tab, your active plan shows an EXTEND button: it's just a purchase of the same tier that stacks more time on top of your current expiry. Buy it whenever you like; if you let the plan lapse, you simply re-buy it to start a fresh term.

Upgrading mid-term

Upgrading to a higher tier while still active gives you credit for the unused portion of your current plan (prorated), charges only the difference, and resets your expiry to a full new term of the higher tier.

Tips & Support

The Tip tile in the Shop lets you support development with a SOL donation — and doubles as a contact form. Every tip or message reaches the author by email, always with your address attached so they can reply.

Two ways to send

Writing a message

Add an optional short message (up to 32 characters) — a thank-you, a feature request, or a bug report. It's attached to the email together with your account email, so the author can follow up with you directly.

Your Wallet

Every FlipTrainer account comes with a real Solana wallet, generated entirely in your browser. It's used to pay for subscriptions — never for simulated trades.

Key generation

When you sign in for the first time, FlipTrainer generates an Ed25519 keypair in your browser using the Web Cryptography API. The private key is encrypted before it ever leaves your device.

Finding your wallet address

Your public wallet address is displayed in the extension popup (click the FlipTrainer icon in the Chrome toolbar). Copy it from there to send SOL from another wallet or a centralized exchange.

Cross-device recovery

Your key lives only on the device that created it — it's never stored on our servers, so a new device can't recover it automatically. To use the same wallet elsewhere, export your private key from the Wallet page and import it on the new device (the imported key's public address must match the one bound to your account). Alternatively, you can create a brand-new wallet, which re-binds your account to the new address.

Funding Your Wallet

To purchase or extend a subscription, you need real SOL in your FlipTrainer wallet. This is the only place in FlipTrainer where real funds are involved.

How to add SOL

Security

Your wallet's private key is generated and encrypted in your browser. FlipTrainer servers never see your plaintext private key.

Key encryption

Your private key is encrypted with AES-GCM before it leaves your browser. The encryption key is derived using HKDF:

keyMaterial  = HMAC-SHA256(serverPepper, userID)
encryptionKey = HKDF(SHA-256, keyMaterial, randomSalt, "fliptrainer-wallet-v1")
               → 32-byte AES-GCM key

The serverPepper is a secret stored only as an environment variable on the server — never in the database. Even a complete database breach would not expose your private key without the pepper.

What the server stores

The server never signs for you

Because your key never leaves your device, FlipTrainer's servers cannot sign transactions on your behalf — there is no auto-renewal and no server-side custody. Every payment is signed locally in your browser. The accepted trade-off: if you lose your device without an exported key, the funds cannot be recovered by anyone, including us.
