Live rankingAugust 9, 2026
The ten highest-paying USDC strategies in this index ran from 6.01% to 10.48%, across Base, Arbitrum and Ethereum.
Sorted on the 24-hour rate with no floor applied: a rate at the top of this table can sit on a few hundred dollars of liquidity. The headline figure above uses a $50K floor for that reason, and 7 of the 54 strategies cleared it. Open any row for its tracked value and history.

Pick an amount and any of the 54 tracked USDC strategies, and the calculator below works out a year of earnings from the rate on record.
Enter an amount, pick a strategy, then calculate.
Educational only. The figures extrapolate one day’s rate across a full year and assume it holds, which no onchain rate does. Rates move with borrower demand, with reward programs that start and stop, and with how much liquidity sits in a strategy at the time. A large enough amount can move the rate it earns. Nothing here is advice, an offer, or a forecast.

Mechanism
USDC lending yield is the interest borrowers pay when USDC is supplied to a money market such as Aave or Compound.
Someone is on the other side of every rate here, and on a money market that someone is a borrower posting collateral worth more than the loan. Most of them are taking leverage: borrowing dollars against ETH or BTC to hold a larger position than they could pay for outright. That demand rises and falls with the market, which is why a supply rate is cyclical rather than fixed, and why a double-digit rate on a lending market usually means leverage is expensive at that moment rather than that the venue is generous.
Because the loan is over-collateralised, the lender is protected by liquidation rather than by the borrower’s promise. If the collateral falls far enough, a liquidator repays the loan and takes the collateral at a discount. The rate compensates for the possibility that this fails to happen fast enough, which is where bad debt comes from and why what backs a market matters as much as who runs it.
Autocompounding strategies sit one layer above that. A contract harvests the reward emissions, sells them, and puts the proceeds back into the position on a schedule, which is why their published rate moves more than a plain supply rate and why part of it depends on the price of a token rather than on interest. A smaller group runs delta-neutral, holding USDC against a short leg so the yield comes from funding rather than from borrower demand. A few rows are real-world-asset credit, where the yield traces back to short-dated government paper rather than to anyone onchain, and those rates move with policy rather than with crypto leverage.
Every one of those patterns buys either a higher or a steadier rate by adding smart-contract surface, and the vault page for any row spells out which contracts a position touches.
CompositionAugust 9, 2026
Of the 54 USDC strategies tracked here, 18 earn lending interest alone and 36 earn lending interest plus a reward token the strategy harvests and sells.
A strategy earning lending interest alone pays in dollars, and the rate is what it says. A strategy that also earns an emission is holding a token it has to sell, so part of that rate is worth whatever the token fetches on the day the strategy harvests it. The reward tokens across this index were MORPHO on 30, ARB on 6, COMP on 3 and EXTRA on 2 strategies. Median rates sit close together: 5.00% for the interest-only group against 4.44% for the group carrying an emission, so an emission is rarely what makes one strategy pay more than another.
Where the reading stops is worth stating, because the obvious next question has no answer in our data. The upstream feed publishes one rate per strategy and the list of tokens that rate involves, and nothing that divides the rate between interest and emission. So this page reports which tokens a strategy earns and declines to publish a base-versus-reward split, which would be a number invented here rather than measured anywhere.
One label needs a caveat. Aave has stopped issuing AAVE emissions on its USDC markets, and the feed has not caught up: three Aave rows still carry an AAVE token label while two identical Aave positions on Ethereum carry none, and all five pay within a point of each other. Those three are counted here as interest-only, which is what they are.
StabilityAugust 9, 2026
Across the 53 USDC strategies with a month of readings behind them, 28 moved by less than a percentage point over the 30 days to August 9, 2026, and the rest moved more.
Among the strategies holding at least $50K, the steadiest over the trailing 30 days was USDC Alpha Core V2 on Ethereum, which held a standard deviation of 1.07 points around a mean of 7.25%. The widest was USDC MORPHO on Base, which ranged from 10.94% to 30.23% over the same window, a standard deviation of 4.23 points.
Deviation is the figure that tells you whether a headline rate is a rate or a spike. A strategy paying more than its own monthly mean on the day you read it has usually just received an emission or seen a jump in borrowing, and neither lasts. A strategy whose deviation is a fraction of a point has been paying roughly the same thing all month, which is the more useful property if the position is meant to sit. Standard deviation describes what a rate did over the window measured. It is not a forecast, and it says nothing about the contract, oracle or peg exposures set out below.
By venueAugust 9, 2026
Among the venues in Harvest's USDC index, Morpho paid a median of 4.44% across 27 markets, Autopilot paid a median of 6.09% across 4 markets and Morpho Market paid a median of 4.44% across 4 markets.
What separates these families is the shape of the market underneath, not the brand on the row. Aave and Compound run pooled markets: every supplier of USDC lends into one shared pool, every borrower draws from it, and a single utilisation curve sets one rate for everybody. That design is why their rates cluster within a point or two of each other and move slowly, and it is also why a pooled market can absorb size without the rate collapsing.
Isolated markets work the other way. Morpho runs one market per collateral asset, each with its own loan-to-value ratio, its own oracle and its own interest curve, so a lender picks the exact exposure instead of inheriting the average of a pool. Isolation contains a bad collateral asset to the one market that accepted it, and it fragments liquidity, which is why isolated-market rates spread so much wider than pooled ones across the list above.
A curated vault sits on top of those isolated markets and spreads one balance across several of them. The curator chooses which markets, at what weights, under what caps, and rebalances as rates move. That is where the spread between the bottom and the top of this list mostly comes from: two vaults on the same protocol, holding the same asset, can pay very differently because two different firms picked different markets. It also means the name on the row is the curator, not the venue, and the parameter set can change while a position is open.
RatesAugust 9, 2026
The best USDC rate on a strategy holding at least $50K was 10.48% on USDC 40 Acres on Base, against a median of 4.45% across all 54 strategies tracked here.
What gets searched for as a USDC staking rate is one of the two things ranked on this page: an interest rate paid by borrowers in a lending market, or the yield a vault strategy collects and compounds on a USDC position. Neither one is staking in the protocol sense. The table above sorts on the 24-hour figure, and the 30-day column beside it shows whether that figure is where the strategy has been sitting or a spike on the day.
Definitions
Staking rewards are newly issued network tokens paid to validators for securing a chain, and USDC yield is interest paid by a borrower or a strategy for the use of dollars.
The distinction matters for what the number is exposed to. A staking reward is denominated in the network token, so its dollar value moves with that token's price. A USDC rate is denominated in dollars already, so the headline figure is what the position earns in dollar terms. Some strategies on this page do pay part of their yield in a reward token, and where the upstream protocol publishes that split the vault page shows it separately from the base rate.
DistributionAugust 9, 2026
USDC yield in this index sat on 5 networks, led by Base with 23 strategies and Ethereum with 16.
Full breakdown by network: Base (23 strategies, top APY 10.48%), Ethereum (16 strategies, top APY 6.03%), Arbitrum (11 strategies, top APY 6.56%), HyperEVM (3 strategies, top APY 5.89%) and Polygon (1 strategy, top APY 1.72%).
USDC liquidity concentrates on Ethereum and on the rollups with the deepest stablecoin markets, which is where the larger strategies sit. Rollups matter here for a specific reason: settling on a chain where a transaction costs cents rather than dollars makes frequent harvesting economic, so the same autocompounding design pays more on Base than it can on mainnet at the same underlying rate. Networks come and go from this list as products ship and retire, and any network pill at the foot of the page cuts the same ranking down to one chain.
VenuesAugust 9, 2026
The largest venue families in this index were Morpho (27), Autopilot (4), Morpho Market (4), Aave (4) and Fluid (3).
Most rows are either a single-asset money market such as Aave or Morpho, or an autocompounder wrapping one of those markets. A smaller slice is real-world-asset credit and structured strategies. Curated Morpho vaults are named for their curator rather than for the protocol, so a row reading Gauntlet or Steakhouse is a Morpho market whose parameters that curator sets.
RiskAugust 9, 2026
Every rate on this page is compensation for a specific set of exposures, and eight of them apply across the index: contract, layered contract, collateral, curator, oracle, liquidity, peg and governance risk.
Bridge, operator and economic risk get their own treatment, alongside the tiers and the exclusions, on the risk framework page. Which of these surfaces a given row carries depends on how many layers it has, and the vault page for any row names the contracts a position touches.
QuestionsAugust 9, 2026
10.48% APY, on USDC 40 Acres on Base, as of August 9, 2026. That is the highest 24-hour rate among the 54 USDC strategies Harvest tracks once a $50K liquidity floor is applied. The floor is there because smaller vaults print higher figures on a few hundred dollars, so the unfiltered top of the ranking is usually not a rate anyone is earning at size.
The median USDC interest rate across the 54 strategies in this index was 4.45% as of August 9, 2026, within a range of 0.08% to 10.48%. A money-market interest rate such as Aave or Compound tracks what borrowers pay for USDC liquidity, which is why it usually sits nearer the middle of that range than the top.
USDC cannot be staked in the proof-of-stake sense, because USDC is not a network token and has no validator set. What is commonly called USDC staking is either lending, where borrowers pay interest, or a vault position, where a strategy earns yield and compounds it. Both of those are what this page ranks.
USDC has no native yield. Circle holds the reserves backing USDC and pays nothing to holders, so a USDC balance sitting in a wallet earns zero. Every rate on this page comes from lending USDC to a borrower or supplying it to a strategy that does.
Safety here is a question of what a given rate depends on. A rate from a large lending market with a long onchain history sits on different ground from a rate on a young vault whose yield leans on reward emissions that can stop. The tiers and the exclusions are set out on the risk framework page.
At the median rate of 4.45% as of August 9, 2026, a 10,000 USDC position would earn about $445 over a year, before any rate change. At the top rate of 10.48%, among strategies holding at least $50K, the same position would earn about $1,048. Rates move daily, so neither figure is a forecast.
The useful reference point is the median of whatever cohort you are comparing against. Across the 54 USDC strategies on this page the median was 4.45% as of August 9, 2026, and half the index sat below it. A rate above the median is usually paying for something, most often reward emissions that can stop, a contract with a shorter track record, or a pool small enough that its rate has not been tested by size.
USDC lending yield is the interest borrowers pay when USDC is supplied to a money market such as Aave or Compound. Autocompounding strategies add a contract that harvests reward emissions and puts them back into the position, which is why their published rate blends two sources. A smaller group runs delta-neutral, pairing a USDC position against a short leg to capture funding rather than borrower demand.
Most of these rates are a blend of both. 18 of the 54 tracked strategies earned lending interest alone as of August 9, 2026, and 36 earned lending interest plus a reward token such as MORPHO that the strategy harvests and sells. Our feed publishes one rate per strategy and the tokens beside it, not a split between the interest and the emission, so this page reports which tokens a strategy earns rather than inventing a decomposition it cannot measure.
No USDC yield is risk-free. Every strategy ranked here carries smart-contract exposure on the vault and on the protocol underneath it, oracle exposure on the price feeds those contracts trust, and depeg exposure on USDC itself in tail scenarios. USDC has held its dollar peg in normal conditions, though it traded as low as $0.87 in March 2023 when part of the reserve sat at Silicon Valley Bank. Size is a further signal: 47 of the 54 strategies tracked held under $50K as of August 9, 2026, so their published rates have not been tested by much liquidity.
Lending APY follows borrower demand and utilisation. Reward APY follows incentive programs that switch on and off. Both move daily, which is why this page carries a 24-hour rate and a 30-day mean side by side.

How to read thisAugust 9, 2026
Both tables carry the same seven columns, and the useful judgements come from reading them against one another rather than from the rate alone.
Tracked value is deliberately not a column here, and it is the reading that decides whether a rate is real. The 54 strategies on this page held $5.3M between them and only 7 cleared $50K, so a rate at the top of an unfiltered sort can be sitting on a few hundred dollars, where the arithmetic still works and nobody is earning it at size. Open any row to see what it holds before reading its rate as an opportunity.
The network and protocol filters above each table narrow rows that are already rendered on the page rather than fetching new ones, so nothing enters or leaves the underlying index when a filter is applied.
ScopeAugust 9, 2026
This page is a curated index of USDC yield strategies, not a census of the USDC yield market.
Strategies are added as they are vetted and integrated, and dropped when the upstream product retires or fails the risk framework. Every comparison here is a comparison within that set, and the rules behind the set are on the methodology page. Plenty of USDC yield exists outside it.
Data reflected on this page is an aggregation of historical data and sorted by best (e.g. highest historical performance), and is not a promise of continued performance or guaranteed results.
