Pool shares, price curves, fees, divergence loss, concentration, and withdrawal risk.

By the end, you should be able to

  • Explain what a liquidity provider owns.
  • Describe price impact and divergence loss.
  • Compare fee income with changing pool composition and risk.
Worked example · illustrative values

The pool rebalances as prices move

A provider owns a share of pool assets

Depositing assets into a pool generally creates a claim on a proportion of its current balances. Traders change those balances, and fees may accrue to providers according to protocol rules.

Relative prices change the pool composition

Arbitrage trades move pool prices toward external markets. Compared with simply holding the original assets, the provider can end with a different mix and lower value. This is often called impermanent or divergence loss.

Evaluate the full return and full risk

Fees and incentives may offset some loss, but returns depend on volume, range selection, token prices, contract behavior, and incentive-token value. Withdrawal may also incur network costs.

Keep the signal in context

What this does not tell you

  • “Impermanent” does not mean the loss must reverse.
  • Incentive yields can fall or be paid in volatile tokens.
  • Concentrated liquidity can become inactive outside its selected range.
Practical exercise

Review a pool without depositing

Use public pool information to identify the variables that drive provider outcomes.

  1. Identify the pool pair, network, fee tier, liquidity, and recent volume.
  2. Record whether liquidity is concentrated or full range.
  3. List contract, token, price, and incentive risks before considering headline yield.

1. What does a liquidity provider usually hold?

2. What should fee income be compared with?

3. Does “impermanent” guarantee recovery?
