PERP DEXs ARE NOT ALL BUILT THE SAME 👀

Everyone talks about volume, TVL and points.

But almost nobody asks the more important question:

How does your trade actually get executed?

There are several major models:

🥇CLOB / Order Book

Think Binance-style trading.

You place a buy order → it sits in the book → another trader/MM sells to you.

Example:

BTC

Bid: $118,000

Ask: $118,005

Your order gets matched against available liquidity.

Examples:

→ Hyperliquid

→ Lighter

Best for: active traders, limit orders, tight spreads and transparent price discovery.

🥈Fully On-Chain Order Book

Same basic idea as a CLOB, but the key difference is where the order book/execution infrastructure lives.

Example:

You place a BTC limit order.

Instead of relying heavily on an off-chain matching system, the protocol is designed around on-chain order-book infrastructure.

Example:

→ TxFlow

The interesting part here is the trade-off:

Transparency + verifiability vs performance + infrastructure complexity.

🥉RFQ

RFQ = Request For Quote.

Instead of looking at a public order book, you ask market makers:

“I want to buy $1M BTC. What's your best price?”

MM A: $118,020

MM B: $118,012

MM C: $118,005

You take the best quote.

Examples:

→ variational

→ Other institutional/RFQ-style venues

This can be very attractive for large trades where you don't want to push through an order book.

4. AMM / Liquidity Pool

No traditional order book.

You trade against protocol liquidity.

Example:

You want to long BTC.

Instead of matching with another BTC seller, your position interacts with the protocol's liquidity/risk system.

Examples:

→ GMX

→ Gains Network

The liquidity model is completely different from Hyperliquid.

5. Hybrid Models

Why use only one mechanism?

Some protocols combine multiple liquidity sources.

For example:

Order Book + AMM + JIT Liquidity

A trader submits an order → existing order-book liquidity can fill part of it → JIT makers can compete for the flow → other liquidity mechanisms can help complete the trade.

Example:

→ Drift
