# Execution Logic

Pear Protocol is a **trading interface**, not a custody layer or risk engine. It allows traders to seamlessly open and manage **pair trades using perpetual futures** by routing long and short orders to your preferred venues — all from a single, unified front end.

#### 🧠 How it works

* **Venue Routing:**

  When a user places a trade, Pear splits the position into a **long leg** and a **short leg**, and routes each side to the selected venue (e.g. GMX, Hyperliquid, Vertex, or SYMMIO).
* **Synchronized Execution:**

  Both legs are executed at the **same timestamp**, enabling operational efficiency and minimizing execution mismatch — critical for effective pair trading.
* **Perpetual Instruments:**

  All instruments traded via Pear are **perpetual futures**, with configurable leverage, margin allocation, and side-specific sizing.

#### 🔐 Fund Flow & Custody

* **GMX:**

  You trade directly from your connected wallet. Pear signs and submits transactions that interact with GMX contracts on your behalf.
* **Hyperliquid / Vertex / SYMMIO:**

  You deposit funds into the protocol-specific trading engine. Pear then acts as a **management and execution layer**, allowing you to view, open, and close positions without ever holding custody of assets.

> Pear does **not** hold or custody user funds.
