Yield Strategies & Real Yield vs. Emissions

When a DeFi dashboard shows "32% APY," the relevant question is almost never "is that number correct?" It is almost always "what is the source of that yield?" Yield in DeFi comes from a small number of structural sources, and the difference between them determines whether a strategy is a durable income stream or a slow ladder into a token you will be unable to sell. The clean categories are roughly: **Real yield (protocol revenue).** Fees paid by users of a protocol that are then distributed back to token holders or LPs. Examples: Uniswap V3 LP fees, Aave borrow-rate-minus-supply-rate spread, GMX trader fees paid to GLP/GMX stakers, Lido staking fees that flow to LDO holders via the DAO. This yield exists whether or not the protocol prints tokens. **Staking yield.** Block rewards paid by a Layer 1 to validators (or stakers of a liquid staking derivative). This is real in the sense that it is paid in the protocol's native asset by the protocol itself, but it is also new-issuance: it dilutes non-stakers and partially offsets the nominal yield. For Ethereum, the post-merge issuance plus MEV gives stakers roughly 3-5% APR depending on conditions, of which only the MEV share is "real" external income. **Token emissions (incentives / liquidity mining).** The protocol prints its own governance token and pays it out to users who deposit or LP. The dollar-value yield depends entirely on the price of the emitted token. Emissions can bootstrap a protocol and can be partly justified as a cost of customer acquisition, but they are not in any economic sense "yield" — they are a transfer from future token holders to current depositors. When emissions stop or the token price falls, the yield evaporates. **Points / airdrop farming.** A 2023-2025 phenomenon where protocols promise future token allocations to users who deposit, transact, or refer. Points are unprice-able until tokenization happens, and the realized yield is often a small fraction of what the marketing suggests. Some points programs (notably Eigenlayer-era restaking points and several L2 user campaigns) have produced real, large returns; many have not. Most yield in DeFi is a blend. The skill is decomposing a headline APY into its constituent pieces — what fraction is real revenue, what fraction is emissions, and what fraction is points/speculation — and pricing each piece honestly.
