If you're looking at yield options on OP Mainnet and wondering where to even start, you're not alone. The list of pools can feel overwhelming, and it's tempting to just sort by the highest number and pick that one. That instinct is worth resisting.

What the Numbers Are Actually Telling You

Two figures appear on almost every staking comparison: APY and TVL.

APY (Annual Percentage Yield) is the estimated return you'd earn over a year if conditions stayed the same. The catch: conditions rarely do. A high APY often reflects reward-token emissions — a protocol handing out its own tokens to attract deposits. Those rewards can shrink or disappear, and if the token's price drops, your real return can too. APY is a snapshot, not a promise.

TVL (Total Value Locked) is the total amount of money deposited in a pool or protocol. It's a rough size indicator. A larger TVL means more people have scrutinised and used the protocol — but it is not a safety guarantee. Bugs, exploits, and depegs can hit large protocols too.

Take the largest pool currently listed on OP Mainnet by TVL: BUIDL, from the BlackRock BUIDL protocol, sitting at around $26 million TVL with a 3.2% APY. That's a relatively modest yield — roughly in line with traditional fixed-income rates. The size of the pool tells you it has attracted significant capital. What it doesn't tell you is the full picture of risks, lock-up conditions, or how that yield is generated. Those details matter.

Why Comparing Beats Chasing

The most useful thing you can do on any chain — OP Mainnet included — is compare several options side by side rather than gravitating toward whichever APY looks biggest. A triple-digit APY on a pool with a tiny TVL and a brand-new protocol should prompt serious questions, not excitement.

Ask yourself: How is this yield actually generated? How long has this protocol been running? What happens if I want to exit?

The comparison table lets you filter OP Mainnet pools so you can see APY and TVL together, in context.

A modest, transparent yield from a well-established protocol is worth understanding fully before a flashy number from an unknown one. Use the data to ask better questions — not to find a shortcut.
