Dev Mode - BNB

Binance Dev Mode lets you manually drive trades on the BNB chain using your Leap task system. It runs a local Dev Mode socket server so you can trade using PancakeSwap or Four.meme — all while keeping your existing analytics and tracking logic active.

⚙️ Getting Started

Step 1 — Navigate to Dev Mode

From the Leap dashboard: Tasks → Create Task → Dev Mode

Then select your BNB wallet.

💡 If you only have Solana wallets, go to Accounts → Add Wallet and add a BNB wallet first. The form will then unlock BNB-specific settings.

🧾 Task Setup Fields

Here’s what each field in the Dev Mode setup means:

Field	Description
Task Name	A simple label to identify your dev session. Appears in the Tasks list and on the web dashboard.
Wallet	The BNB account funding trades. Selecting a BNB wallet automatically enables Pancake, Flap, and Four.meme markets.
Optional BNB Wallet	Lets you direct buys from a secondary BNB account while keeping a Solana wallet active elsewhere. Leave blank unless you need that split.
Buy Amount (BNB)	Default size for manual buys. You can edit this before starting or override per trade in the extension.
Buy Wallet %	Caps how much of your balance each buy can use — useful for running multiple positions simultaneously.
Slippage (%)	Protects against volatile prices. Small-cap launches often require 10–20%. Adjust higher per token if trades fail.
Exchange Toggles	Keep Pancake, Flap, and Four.meme on for BNB markets. Turn off Raydium, Pump.fun, and Meteora (they’re Solana-only).
Gas Settings	Default: Auto, which fetches live gas prices. Use Manual if you want to define exact gasPriceGwei values.
Processors	Optional routing layers: use BlockRazor (requires API key in Settings) or Puissant for relay + tip flow.
BNB Gas Limit	Leave blank for automatic estimation. Set manually if you’ve tested your strategy and want strict control.

🧩 How Dev Mode Works

Once you click Create Task, the app:

1. Spins up a local socket server on your machine.

2. Listens for REST or extension commands at:

   http://localhost:8080/api/extension/trade

3. Executes any "buy", "sell", or "add" actions you send.

4. Streams responses directly to your task activity feed.

🔁 Response Flow

You’ll see live trade feedback in your task feed:

Status	Description
queued	Command received and pending execution
confirmed	Trade completed successfully; includes transaction hash
failed	Validation or network issue (check logs)

---

🚀 Testing a Trade

After starting the task:

1. Use the browser extension or a REST client like Postman.

2. Send the JSON payload above to http://localhost:8080/api/extension/trade.

3. Watch the activity feed for "queued" → "confirmed" → "tx hash".

✅ Once confirmed, your connection is working and ready for live BSC testing.

🧨 Shutting Down Dev Mode

You can stop Dev Mode anytime from the Tasks list. Closing the task automatically shuts down the local server.

⚠️ Keep the task running while testing trades — Dev Mode stops accepting requests once closed.
