AMM (Automated Market Maker)

Definition

AMMs price assets with formulas (e.g. constant product) against liquidity pools. LPs earn fees but take impermanent loss risk, and token incentives can rent depth that disappears when emissions fade.

AMM liquidity is pool depth, not an order book wall. Large swaps move price along the curve; researchers estimate price impact for realistic sizes instead of assuming CEX-like fills. Dilution math belongs beside every emissions-funded yield claim.

Concentrated liquidity designs improve capital efficiency but increase active management needs for LPs. Idle ranges mean your “TVL” may not be the liquidity traders actually hit. UI yield labels lie often; read docs for compounding reality.

For token research, ask whether depth is organic fee business or emissions-rented. Mercenary AMM liquidity is a fragile foundation for a market-cap story. Liquid staking depeg risk is distinct from native validator yield.

Why researchers care

• Pool depth sets practical liquidity.
• IL vs fees is the LP research question.
• Token incentives can rent AMM liquidity.
• Concentrated liquidity can make headline TVL misleading.

How to use it in research

• Simulate a $50k swap on the primary pool — if price impact is severe, rethink size.
• Emissions-heavy pool that drains after rewards cut — mark liquidity as rented.
• Narrow-range LP around a peg — great until volatility blows through the range.

Common mistakes

• Treating AMM TVL as uniformly active depth.
• Ignoring IL when quoting LP returns.
• Assuming aggregator routes eliminate price impact.
