## What Is a ‘Decentralized Exchange’ (DEX) in Cryptocurrency?

A DEX is a peer-to-peer marketplace that allows users to trade cryptocurrencies directly without an intermediary, unlike a centralized exchange. It operates via smart contracts on a blockchain, giving users custody of their funds and significantly reducing counterparty risk and censorship.

## Glossar

### [Single Point of Failure](https://learn.greeks.live/area/single-point-of-failure/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Concentration ⎊ In crypto derivatives, this risk materializes when excessive collateral or governance control resides with a small number of entities, such as a few large liquidity providers or key developers.

### [Counterparty Risk](https://learn.greeks.live/area/counterparty-risk/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Exposure ⎊ Counterparty risk represents the potential loss incurred when a trading partner defaults on their contractual obligations.

### [DEX](https://learn.greeks.live/area/dex/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Architecture ⎊ Decentralized exchanges, or DEXs, represent a fundamental shift in financial market structure, enabling peer-to-peer trading of crypto assets without intermediaries.

### [Smart Contracts](https://learn.greeks.live/area/smart-contracts/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Function ⎊ Smart contracts are self-executing agreements with the terms of the agreement directly written into lines of code, residing on a decentralized ledger.

        "caption": "The abstract composition displays two translucent, mechanical spheres flanking a central, concentric structure bathed in teal illumination against a deep black background, bisected by sharp diagonal planes suggesting rapid data throughput or signal transmission pathways. This visual metaphor captures the high-stakes environment of digital asset derivative trading, where speed and structural integrity are paramount for maintaining collateralization ratios. The central convergence point implies the execution point for complex derivatives like perpetual swaps or tailored collateralized debt positions. Expert application of automated execution protocols demands infrastructure mirroring this geometric precision to manage slippage during order flow injection. The luminous arc symbolizes the defined range within which delta hedging strategies must remain calibrated, minimizing adverse selection risk inherent in opaque peer to peer exchange environments. It conveys the technological scaffolding supporting on chain options pricing models and dynamic collateral posting requirements essential for robust decentralized financial engineering beyond simple spot exchange dynamics."
