# What is DeCA

**DeCA** is the first decentralized application (dApp) that enables users to perform **Dollar-Cost Averaging (DCA)** together in **perpetual futures trading** entirely on-chain.

Through DeCA, users can **create a Pool**, invite others to contribute capital, and receive **shares** that represent their proportional ownership within that Pool. Users hold shares as **proof of ownership** in each DCA CoTrade Pool. To take profit or stop loss, participants must vote to close the Pool. If **at least 51%** of share holders vote to close, the Pool will be terminated and profits or losses are **distributed on-chain** according to each holder’s share ratio.

DeCA transforms the traditional concept of futures trading by integrating the power of DCA into a transparent, collaborative, and community-driven ecosystem.

### **The Problem**

Futures trading has always been a high-risk, high-leverage market. While it offers amplified rewards, it also exposes traders - especially retail participants - to severe liquidation risks during periods of market volatility.

Individual traders often face the following challenges:

* **High leverage exposure:** Small price fluctuations can trigger forced liquidations.
* **Lack of collective trading models:** Most traders act alone, without mechanisms to share risk or pool resources.
* **Poor capital management tools:** Existing platforms fail to integrate DCA strategies effectively within leveraged trading environments.
* **Opaque systems:** Many centralized platforms operate without transparency, creating trust and execution concerns.

As a result, the majority of retail futures traders suffer losses due to over-leverage, isolated risk, and inefficient position management.

#### **DeCA Solution**

DeCA introduces the **CoTrade DCA Pool**, a decentralized trading framework where users can trade perpetual futures **together**, share profits **collectively**, and reduce the risk of liquidation through **automated DCA strategies**.

Each CoTrade Pool functions as a transparent on-chain trading fund managed by smart contracts.\
Every order, margin adjustment, and settlement event is executed trustlessly on the blockchain, ensuring **verifiability, security, and fairness** for all participants.

To enhance user understanding and promote responsible trading, DeCA provides the **CoTrade Pool Simulator**- a powerful analytical tool that allows traders to simulate DCA strategies, visualize risk levels, and estimate profit outcomes before deploying real capital.

By combining **collective participation**, **on-chain transparency**, and **risk-managed automation**, DeCA redefines the future of perpetual trading.

Trading is no longer a solitary battle against volatility.\
It becomes a shared journey of cooperation, data-driven execution, and sustainable growth.
