A 36% annual return sounds like the kind of thing your bank would never offer — and that's exactly why it's worth slowing down before getting excited.

Take ASDCRV on the Concentrator protocol (Ethereum). It currently shows an APY (Annual Percentage Yield — the annualised rate of return, including compounding) of 36.1%, sitting in a pool with a TVL (Total Value Locked — the total amount of funds deposited in a pool) of $2.14 million. Both numbers carry important information, and neither one tells the full story on its own.

Where a Yield This High Usually Comes From

Most double-digit DeFi yields aren't generated from real economic activity — fees, lending interest, or protocol revenue. They're funded by reward-token emissions: the protocol mints its own token and hands it out to depositors as an incentive to attract liquidity. The APY looks great on paper, but if the reward token falls in price — which tokens under constant selling pressure often do — the real return shrinks fast. A 36% APY paid in a token worth half as much in three months is closer to 18%, before you account for anything else.

That doesn't mean 36% is automatically a red flag. But it is a prompt to ask: what is actually paying this yield, and is that source sustainable?

What the $2.14M TVL Signals

A $2.14 million pool is relatively small. TVL is a rough proxy for how much scrutiny a pool has received — larger, older pools with hundreds of millions locked have typically been tested by more users, more market conditions, and sometimes more security audits. A smaller pool isn't necessarily dangerous, but it hasn't had the same level of stress-testing. It can also mean thinner liquidity, which affects how easily you can exit without moving the price against yourself.

ASDCRV itself involves a wrapped or derivative asset — that layer of complexity adds depeg risk: the possibility that the asset drifts from its intended value, compressing or wiping your returns regardless of the APY shown.

One Thing to Do Before Anything Else

Look at what's actually paying the yield, how long that pool has existed, and whether the reward token has its own price history. The comparison table lets you line up pools side by side so you can see how this yield stacks up against simpler, more established options. That context — not the APY alone — is what helps you decide whether a number is interesting or just loud.
