Binance Wallet introduces DEX Pro Mode, featuring Secure Auto Sign for faster, gas-efficient limit orders and enhanced trading tools for advanced DeFi users.

Key Takeaways

DEX Pro Mode launched: Binance Wallet now offers an advanced trading interface for experienced DeFi users.

Secure Auto Sign feature: Automates transaction signing within a Trusted Execution Environment (TEE), keeping private keys secure.

Gas-efficient limit orders: Users can place, modify, or cancel orders with no upfront gas fees, while keeping funds unlocked.

A New Era for On-Chain Trading

Binance Wallet has unveiled DEX Pro Mode, a new upgrade designed for advanced traders seeking more control and efficiency in decentralized trading. The feature introduces Limit Orders powered by Secure Auto Sign, allowing users to set target prices without the friction of constant manual confirmations.

The Pro Mode tab — now live under the Trade section — integrates real-time token data (market cap, liquidity, trading volume, holder stats) directly into the trading flow, reducing the need to switch screens.

Secure Auto Sign: Faster, Safer Limit Orders

The standout feature, Secure Auto Sign (SAS), enables traders to automate transaction signing while maintaining full self-custody.

  • - Runs in a Trusted Execution Environment (TEE): Private keys stay isolated and untouchable — even Binance cannot access them.
    - No repeated approvals: Once authorized, users can place and manage limit orders for 7 days before reauthorization is needed.
    - Verifiable security: The system supports third-party verification of private key protection.

How Limit Orders Work in DEX Pro Mode

Traditional DEX limit orders often lock funds or charge gas upfront. Binance Wallet’s version fixes these pain points:

No upfront gas fees: Gas is only charged when the order executes, meaning cancellations are free.

Funds remain unlocked: Users can continue using their assets while a limit order is active.

Multiple pending orders: The same wallet balance can back several open orders, giving traders flexibility across tokens.

How to Enable and Use Secure Auto Sign
1. Go to [Trade] > [Pro Mode].
2. Select Limit Order and enter your price and amount.
3. Enable Secure Auto Sign (SAS) the first time you use the feature (valid for 7 days).
4. Submit the order.

Each new order resets the 7-day SAS period. If inactive for 7 days, reauthorization is required.
