Exciting news for the Bitcoin community! The Velar Artha PerpDex is gearing up for its highly anticipated mainnet launch, set to revolutionize the world of decentralized finance (DeFi) on Bitcoin. 

As the world's first perpetual decentralized exchange (PerpDex) built on the Bitcoin network, Velar Artha is poised to unleash a new era of leveraged trading opportunities for Bitcoin enthusiasts and DeFi traders alike.

As we prepare for the launch, let's dive into an exclusive explainer of how Velar Artha PerpDex works.

The Velar Artha PerpDex: A Game-Changer for Bitcoin DeFi

At its core, Velar Artha implements an elegantly simple yet powerful system for leveraged trading using pool-based liquidity. This innovative approach brings the sophisticated trading mechanisms typically associated with centralized exchanges to the decentralized world of Bitcoin, all while maintaining the security and transparency that DeFi users demand.

As we countdown to the mainnet launch, let's explore the key features that make Velar Artha PerpDex a true game-changer:

The Basics of Velar Artha PerpDex

At its core, Velar Artha implements a straightforward system for leveraged trading using liquidity pools. Each pool consists of two components:

1. A base coin (e.g., BTC)

2. A quote coin (e.g., USDT)

The price of the base coin is provided by an oracle and is expressed in terms of the quote coin. This setup allows for a simple yet effective trading environment.

How Trading Works

Users can open leveraged positions by providing collateral. When they close their positions, they receive their collateral back, plus or minus their profit or loss (PnL). It's important to note that open positions incur fees, which are deducted from the user's collateral over time.

Types of Fees

1. Funding Fees: Paid by users to other users when there's an imbalance between long and short positions.

2. Borrowing Fees: Paid by all users to the pool/Liquidity Providers (LPs).

3. Transaction Fees: Paid by all users per transaction.

All fees are calculated on a per-block basis and are dynamically adjusted based on pool utilization.

Liquidations

To maintain system stability, positions can be forcibly closed (liquidated) by anyone when a position's collateral reaches a certain low watermark threshold.

The Role of Liquidity Providers (LPs)

Liquidity Providers play a crucial role in the Velar Artha PerpDex system. Conceptually, LPs take the opposite position of users. They supply both base and quote coins to the pool, which are then used to facilitate trading and manage risk.

How LPs Make Money?

1. When a position closes with positive PnL, profits are paid out from the pool reserves.

2. When a position closes with negative PnL, the loss is added to the pool reserves from the user's collateral.

3. LPs can mint LP tokens by providing a mix of quote and base coins to the pool.

4. When Liquidity providers burn their LP tokens, they receive a mix of coins from the pool proportional to their share of the total LP tokens.

5. Liquidity providers profit if the pool value has increased between the time they minted and when they burn their LP tokens.

The Fully Backed System

One of the key features of Velar Artha PerpDex is its guarantee that every open position can always be closed, regardless of price movements. This is achieved through a clever system of reserve management:

1. Pool reserves are split into two parts: available reserves and locked reserves.

2. When a user opens a position, the system calculates the maximum possible payout should the position close in profit.

3. Enough coins to satisfy this potential payout are moved from the available reserves to the locked reserves while the position remains open.

4. When the position closes, the actual payout is calculated and paid from the locked reserves. Any excess is returned to the available reserves.

This system ensures that the pool is always "fully backed," providing security and stability for all participants.

Dynamic Fee Adjustment and Risk Management

The Velar Artha PerpDex system incorporates dynamic fee adjustments based on pool utilization. This helps to manage risk and maintain balance within the system. 

As pool utilization increases, fees may be adjusted to incentivize or disincentivize certain behaviors, ensuring the overall health of the ecosystem.

Conclusion

The Velar Artha PerpDex mechanism offers a simple yet powerful approach to leveraged trading in the DeFi space. By combining pool-based liquidity, dynamic fee structures, and a fully backed system, it provides users with a secure and efficient trading environment. 

As the DeFi landscape continues to evolve, innovations like Velar Artha PerpDex demonstrate the potential for creating more accessible and robust financial instruments.
