How this rate has behaved
SYN shows up in 2 pools here, with rates from 0.03% to 6.61% APY across 1 chains — the rate depends on which protocol and chain you pick, not just the token.
2 of these 2 pools have a trustworthy 30-day average on file, with a median of 16.78% — a useful check against today's number for whether the rate is steady or just having a good day.
All 2 pools pay a plain base rate right now — no incentive or reward APY mixed in.
2 of 2 pools carry impermanent-loss risk, meaning a two-sided position can lose value against just holding, even while it earns yield.
| Protocol | APY | 30d Mean APY | Yield mix |
|---|---|---|---|
| frax | 0.03% | 0.05% | Base rate |
| sushiswap | 6.61% | 33.51% | Base rate |
The 30-day average comes straight from DefiLlama and only appears when it passes the same sanity rail as every other number on this page — a dash means it didn't clear that bar, not that it's being hidden. Every pool here already clears a $100K minimum TVL. Rates move daily, so treat this as a snapshot, not a promise.
