The market segments and what they are paid for

DEX, lending, stablecoin, staking — four mechanics, four yield sources, four different risks.

This lesson has had no expert review. It was written for this platform and against the evidence it cites; nobody has gone through it independently.

Learning objectives

  • You can say, for a given market, who pays the yield and for what.
  • You can explain why the same percentage means different things in two segments.

Core concept

Fact

Four mechanics, four payers

At a DEX, traders pay a fee to liquidity providers. In a lending market, borrowers pay interest to depositors. With a stablecoin, the issuer earns on the reserve and may pass some of it on. In staking, the network pays for securing it — from emissions or from transaction fees. Naming the payer means understanding the yield source.

Interpretation

Same number, different meaning

Five percent at a DEX means trading volume — and comes with impermanent loss when prices diverge. Five percent in a lending market means borrowing demand — and comes with liquidation and utilization risk. Five percent from emissions means dilution. The percentages compare; the risks behind them do not.

Risk

The segments stack

A yield product deposits capital into a lending market that accepts a stablecoin as collateral whose price comes from an oracle. Seeing only the top segment shows a return; seeing the chain shows four places where something can fail. That is exactly why composability is at once DeFi's most important property and its most important source of risk.

Definitions

AMM in the glossary
A trading mechanism that forms prices from a pool's balances by formula rather than through an order book.
Impermanent loss in the glossary
The difference in value between holding assets in a pool and simply holding them.
Liquid staking in the glossary
Staking in which the locked position is represented by a tradable token.

Model

  1. DEX → traders pay fees to liquidity providers

  2. Lending → borrowers pay interest to depositors

  3. Stablecoin → reserve earnings, at the issuer

  4. Staking → the network pays from emissions or fees

  5. Incentive program → the protocol pays from its own emissions

Who pays the yield? — Only the first four have a payer outside the protocol.

Worked example

Two pools with identical APY

Pool A
lending market, stablecoin, APY 5.0 % (base 4.6 %)
Pool B
DEX pool, two volatile tokens, APY 5.0 % (base 0.4 %)

Same total APY, different composition: A comes mostly from borrowing interest, B almost entirely from emissions — and B additionally carries impermanent loss.

The 5 % is not the same quantity.

Reading: Comparing on APY alone presents two different risks as equal. The base component is the figure that makes the difference visible.

Two pools show 5 % APY. Which figure distinguishes them fastest?

Exercise on real data

Find one lending market and one DEX pool with a similar APY and compare the base component. Note which of the two would persist without incentive payments.

Application

A yield product quotes 9 % and deploys capital across three protocols. What do you ask first?
