How this rate has behaved
USDD shows up in 3 pools here, with rates from 0.02% to 4.04% APY across 3 chains — the rate depends on which protocol and chain you pick, not just the token.
3 of these 3 pools have a trustworthy 30-day average on file, with a median of 0.77% — a useful check against today's number for whether the rate is steady or just having a good day.
1 of 3 pools blends in incentive or reward APY on top of the base rate. Incentive yield decays over time as reward programs run down — the base rate is the more durable number.
| Protocol | APY | 30d Mean APY | Yield mix |
|---|---|---|---|
| justlend-v1 | 4.04% | 4.00% | 99.98% incentives |
| raydium-amm | 0.02% | 0.77% | Base rate |
| uniswap-v3 | 0.02% | 0.00% | 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.
