How CLOBs, AMMs, and RFQs Fit On-Chain Trading
Summary
The article compares central limit order books (CLOBs), automated market makers (AMMs), and request-for-quote systems (RFQs) as mechanisms for decentralized trading. It explains that public transactions can expose limit orders to frontrunning, while AMMs avoid publishing individual liquidity orders by pooling capital and quoting across prices. That design requires traders to execute against the pool and can impose slippage and costs to liquidity providers.
The article proposes matching mechanisms to trade characteristics: CLOBs for trades of varied size in less correlated markets, AMMs where assets are highly correlated, and RFQs for large trades with moderate correlation. It argues that chain-specific limits, including fees and transaction visibility, will shape which mechanisms work best, and anticipates hybrid systems combining their strengths. These are qualitative recommendations rather than a measured comparison; the article supplies no detailed performance data or formal model, and its mechanism rankings are simplified.
Key ideas
- Public order visibility on decentralized networks can expose limit orders to frontrunning.
- AMMs pool capital and stream prices, reducing the need to publish individual liquidity orders.
- AMM traders execute against the pool and may incur slippage as a cost of the mechanism.
- The article associates CLOBs with less correlated markets, AMMs with highly correlated assets, and RFQs with large trades in moderately correlated markets.
- Trading mechanisms may need to be tailored to each chain and combined in hybrid designs.
