Last time, we covered decentralized wallets. Today, let’s dive into the core of DeFi—Decentralized Exchanges (DEX).
A DEX fundamentally differs from centralized exchanges by allowing anyone with a decentralized wallet (e.g., MetaMask) to instantly access services like token swaps, transfers, and yield farming—no intermediaries required.
Why DEX Matters
DEX emerged to bypass the bottlenecks of centralized exchanges, where token listings demand audits, fees, and long queues. With DEX, projects can self-provide liquidity, proving their value and accelerating blockchain adoption.
How DEX Works
DEX platforms revolve around two primary functions:
- Token Swapping: Trade tokens directly; costs include gas fees.
- Liquidity Provision: Users lock assets into Automated Market Maker (AMM) pools (e.g., ETH/USDC) to earn gas fees and rewards.
