Frequently asked
USDT on OP Mainnet — common questions
Is earning yield on USDT on OP Mainnet safe? +
Every pool carries smart-contract risk. LP and lending pools layer on impermanent loss, liquidation, or oracle risk depending on the type. Stick with audited protocols, large TVL, and rates close to the median — outliers usually carry hidden risk.
How do I get USDT onto OP Mainnet? +
Most users bridge from a major exchange or use a chain-native bridge. Always test with a small amount first. Bridge fees + gas can be significant for small deposits — check the math before moving anything under $200.
What's the highest USDT yield on OP Mainnet? +
Right now Zerobase Cedefi pays roughly 5.3% APY — the top of our ranking. Higher published rates exist on smaller pools, but those usually fail the size + sanity filter we apply.
How are these yields calculated? +
Each yield combines base rewards plus any incentive token rewards, annualised. Rates fluctuate daily. We refresh hourly and only show pools above $1M TVL with rates between 0.01% and 30% to filter out scams and stale data.
