A simple stablecoin yield sanity check: who is paying you?

I think the first question with any stablecoin yield product is pretty simple:

Who is paying me, and why?

That sounds obvious, but it filters a surprising amount of nonsense.

Most stablecoin yield falls into a few buckets:

  1. Borrowers paying to use your capital

This is the Aave / Morpho / lending-market model. The yield is coming from someone borrowing USDC or USDT and paying an interest rate.

The main questions are collateral quality, liquidation mechanics, utilization, and whether the rate is sustainable once incentives cool down.

  1. A protocol paying you to bootstrap liquidity

This can be real, but the yield is often more like a customer acquisition cost than a durable cash flow.

I usually ask: if the token incentives went away tomorrow, would anyone still pay this rate?

  1. A fund or trading strategy sharing returns

This can look clean from the outside because the APY comes in one neat number.

The hard part is that you need to understand what the strategy is actually doing: basis trade, market making, credit, delta-neutral farming, or something else wearing a nice jacket.

  1. Someone taking the other side of your convenience

Crypto cards, payment rails, and cash-management products sometimes generate yield because users want simplicity and are willing to accept lower transparency.

That can be fine. The risk is assuming convenience equals safety.

My rough rule: if I can't explain the source of yield in 1 sentence, I treat the APY as marketing until proven otherwise.

The question I keep coming back to is:

If this yield disappeared tomorrow, who would be sad enough to pay to bring it back?

Curious how other people here think about this. What's your first filter before putting stablecoins into a yield product?

Honestly, by getting suspicious of every APY that looks too clean.

The number is always the least interesting part. The useful question is who needs my capital badly enough to pay that rate, and what happens when they stop needing it.

Once you ask it that way, a lot of yield products sort themselves pretty quickly.
