3. Holder Yield and Live DeFi Yield Links
Issuer reserve income and holder yield are separate fields. Most fiat-backed stablecoin terms state that the token itself does not pay holder interest. USDe and USDS have separate savings or staked-token paths through sUSDe and sUSDS where eligible. Third-party DeFi lending yield depends on protocol liquidity, borrow demand, incentives, chain, pool parameters and smart contract risk.
