Sui has a growing list of yield options, and if you're new to the chain, the first thing you'll notice is how different those numbers look from one pool to the next. Before you pick the one with the biggest APY, it helps to understand what you're actually comparing.
What APY and TVL Are Telling You
APY (Annual Percentage Yield) is the annualised return a pool is advertising — but it's a snapshot, not a promise. It can change daily, and it often does. TVL (Total Value Locked) is the total amount of money sitting in a protocol. Think of it as a rough size indicator: a larger TVL means more people have put money in, which usually means the protocol has faced more scrutiny. That's not a safety guarantee, but it's a useful starting point.
A practical anchor: on Sui right now, one of the largest pools by TVL is USDY on the Ondo protocol — roughly $23 million locked, with an APY around 3.6%. That's a modest, stablecoin-style return. It looks boring next to triple-digit yields you might spot elsewhere on the same chain. But that "boring" number is worth understanding: it's closer to what a sustainable, asset-backed yield looks like. Anything dramatically higher is almost always driven by reward-token emissions — the protocol paying you in its own token to attract deposits. Those emissions don't last forever.
Why Chasing the Top APY Tends to Backfire
When you sort any chain's pools by APY and jump to the top, you're usually looking at the newest, smallest, or most experimental options. Small pools carry higher liquidity risk — it can be harder to exit when you want to. Newer protocols haven't been tested by time or adversarial conditions. And if the yield is coming from token rewards rather than real protocol revenue, the APY can collapse the moment incentives are cut.
This doesn't mean high-APY pools are always wrong to consider — it means they deserve more questions, not fewer.
A Better Starting Point
Rather than filtering for the highest number, try filtering for pools where the TVL is substantial and the APY feels proportionate to the asset type. Stablecoins offering triple-digit yields should raise an eyebrow; single-digit yields on a large, established pool tell a different story.
The comparison table lets you sort Sui pools by both APY and TVL side by side — which makes it easier to spot when a high return is an outlier worth investigating, rather than a deal worth rushing into.
