What is a DEX?
A DEX is a Decentralized Exchange. It is a place where people trade crypto without a middleman.
On a regular exchange like Coinbase, the company matches buyers and sellers. On a DEX, a smart contract does the matching. No company involved.
How Does Trading Work on a DEX?
Instead of an order book (buyers and sellers posting prices), a DEX uses liquidity pools. A pool is a pot of two tokens. Anyone can trade one token for the other.
Example: A WETH/USDC pool holds ETH and USDC. If someone wants to buy ETH, they put USDC in and take ETH out. The pool charges a fee for this service.
That fee goes to the people who put money in the pool. Those people are called liquidity providers. When you deposit on Snuggle, you become a liquidity provider.
Why Use a DEX?
- Trade 24/7. No market hours.
- No signup or identity verification.
- You keep your tokens in your own wallet.
- Usually cheaper than centralized exchanges for large trades.
The Big DEXs
Uniswap: The largest DEX. Invented the modern liquidity pool model. Over $1 trillion in total volume.
Aerodrome: The biggest DEX on Base. Offers extra AERO token rewards to liquidity providers.
PancakeSwap: Originally built for BNB Chain. Now on Base too. Offers extra CAKE token rewards.
Snuggle works with all three.
