Yield Reality Check

Every yield page in crypto leads with a headline APY. That number is usually two different things added together: what the pool genuinely earns from fees, and tokens being printed to attract deposits. This splits them, so you can see what you would still be earning if the incentives stopped tomorrow.

Why a 40% APY is often a 3% APY wearing a costume

A yield figure is usually two different things added together. There is what the pool genuinely earns, which is fees paid by people trading through it or interest paid by people borrowing from it. And there is what is being printed, which is a reward token issued to attract deposits. Both appear in the headline. Only one of them survives the incentive programme ending.

This splits them. The green part of each bar is yield the pool earns. The amber part is emissions. If the amber part disappeared tomorrow, the green part is what you would still be getting, and that is the number worth comparing against anything else you could do with the money.

The three questions worth asking about any yield

  1. Where does the money actually come from? Fees paid by real users are durable. Tokens printed to attract capital are a marketing budget, and marketing budgets end.
  2. What am I holding while I earn it? A two asset pool exposes you to impermanent loss: if the assets move apart you end up with more of the loser. The yield has to beat that before you are ahead of simply holding.
  3. Can I get out? A small pool is easy to enter and hard to leave, and a large deposit dilutes the very yield that attracted it. Pool size is shown on every row for that reason.

What this does not tell you

Nothing here is a view on whether a protocol is safe. A pool can pay a genuine, well earned yield right up until the contract holding the money is exploited, and yield data cannot see that coming. The rate is only one of the risks and usually not the one that costs people everything.

Questions people ask

Why is the APY I actually receive lower than the one advertised?

Usually because a large share of the advertised figure was paid in a reward token rather than earned, and that token fell in value between being issued and being sold. The headline assumes you receive the token at the price on the day and sell it instantly. In practice the emissions themselves push the price down, because everyone earning them is also selling them.

What is the difference between base APY and reward APY?

Base APY is money the pool actually generates: trading fees from people swapping through it, or interest from people borrowing. It exists because someone is paying for a service. Reward APY is a token the protocol prints to attract deposits. It is a marketing cost, it is finite, and when it ends the yield falls to the base rate. This tool shows both, and states what the base rate is on its own.

Is a high APY always a warning sign?

Not always, but a very high one nearly always means either heavy emissions or a small pool where a modest amount of fee income divides across very little capital. Neither survives money arriving. The useful question is not how high the rate is but what is paying it and for how long.

What is impermanent loss and does it apply here?

It applies to any pool holding more than one asset. The pool automatically sells whichever asset is rising and buys whichever is falling, so if the two move apart you end up with more of the loser than you started with. Compared to simply holding both, you are behind, and the yield has to cover that gap before you are ahead. Every row here says whether it applies.

Does a good yield mean the protocol is safe?

No, and this is the most important limitation of the page. Yield data says nothing about whether the contract holding your money can be exploited, whether the team can withdraw it, or whether the protocol is solvent. A pool can pay an entirely genuine yield right up until the moment it is drained. The rate is one risk and usually not the one that costs people everything.

Where does this data come from and does it cost anything?

Live pool data from a public source, read fresh when you load the page, free, with no sign up and no wallet connection. Pools reporting outlier or impossible rates are excluded from the ranking and the number excluded is shown, because a four figure APY is a data artefact rather than an opportunity.
