USDC pays no interest by itself, so any USDC interest rate comes from lending it, depositing it in a vault, or holding it at a custodian that shares reserve income. On October 6, 2026 the main routes paid between 3.2% and 5.2% APY, with Maple syrupUSDC at 5.18%, Fluid at 4.83%, and Aave v3 at 4.60% on Ethereum, per DeFiLlama.
​

Custodial Coinbase pays 3.75% on USDC to Coinbase One members, paid weekly with no lockup. The table below lists each route with its rate, size, and main risk, all pulled from DeFiLlama yield data the same day, so you can compare like for like.
​

USDC is a payment stablecoin, and Circle keeps the interest its reserves earn. Yield on USDC therefore always comes from somebody else: a borrower paying interest, a vault strategy, a yield-bearing wrapper you swap into, or a custodian rebating part of its own income. Each source carries a different risk.
​

The four risk buckets are custodial credit risk (Coinbase, Maple), smart contract risk (Aave, Compound, Fluid, Morpho, Kamino), funding-rate risk (sUSDe), and Treasury-duration risk (tokenized funds such as BUIDL). Live APYs across hundreds of USDC pools are tracked by DeFiLlama.
​

Rates below are base supply APYs, excluding temporary token incentives, pulled from DeFiLlama on October 6, 2026. TVL is rounded. Morpho vault rates are set per vault and are not listed as one figure, so check the vault page before depositing. Rates move daily.

What changed since mid-September per DeFiLlama: Aave v3 on Ethereum rose to 4.60% while Compound v3 fell to 3.23%, Maple's pool grew to $2.9B, and Coinbase raised its posted rate to 3.75% per Coinbase. sUSDe now sits close to plain lending rates, which weakens the case for its extra risk.
​

No. USDC is not a proof-of-stake asset, so there is nothing to stake in the validator sense. Platforms that advertise USDC staking are lending it, depositing it into a vault, or paying a custodial reward. Ask which of those is happening before you deposit, because the risk is different for each.
​

For example, Coinbase labels its program USDC rewards and pays it weekly on balances held in the account, while lending markets listed on DeFiLlama pay a variable rate set by borrower demand. Neither is staking, and neither is insured like a bank deposit.
​

Pick by size, jurisdiction, and how hands-on you want to be. Small passive balances in the US suit a custodial reward. Self-custodial users get higher rates in lending markets. Larger books split between a low-risk base and a smaller higher-yield slice. Non-US users have access to more routes than US users.
​

Retail, passive, US: Coinbase Rewards at 3.75% for Coinbase One members, per Coinbase. Retail, self-custodial: Fluid at 4.83% or Aave v3 at 4.60% on Ethereum, or Aave on Base at 3.79%, per DeFiLlama.
​

DAO treasury: a base in sUSDS at 3.60% with $4.8B in TVL per DeFiLlama, plus curated Morpho vaults. Fund or trading desk: Maple syrupUSDC at 5.18% per DeFiLlama, accepting credit risk instead of funding-rate risk.
​

Aave v3 and Compound v3 are the two oldest USDC money markets. You supply USDC, receive a receipt token, and earn a variable rate set by how much borrowers draw. Rates rise when borrowing demand rises. The main risks are contract bugs, oracle failures, and bad debt from liquidations that fail.
​

On October 6, 2026, DeFiLlama showed Aave v3 USDC paying 4.60% on Ethereum with $128M supplied and 3.79% on Base, and Compound v3 paying 3.23% on Ethereum. See our yield farming guide for how these rates are set.
​

Fluid, from the Instadapp team, pools lending and DEX liquidity in one layer so the same capital earns from both. That lets it pay a higher supply rate than older markets at similar collateral risk. It is younger than Aave, so the contract track record is shorter, which is a risk worth pricing in.
​

Per DeFiLlama on October 6, 2026, Fluid USDC lending paid 4.83% on Ethereum with $130M of TVL and 4.38% on Arbitrum with $61M. Treat it as one slice of a self-custodial USDC book rather than the whole book.
​

Morpho runs isolated lending markets where each USDC market accepts one collateral type with fixed risk settings. Curators such as Steakhouse and Gauntlet build vaults that allocate across those markets. You choose the exact risk you take instead of pooling with every borrower, and the vault's collateral list decides the rate.
​

Morpho vault rates are published per vault on the Morpho app, not as one protocol rate on DeFiLlama, so check the live vault APY and its collateral list before depositing. Higher-paying vaults usually accept riskier collateral.
​

Kamino is the main USDC lending venue on Solana. Rates vary by market because each market accepts different collateral, from SOL and BTC to credit products. Some Kamino vaults use leverage internally, so confirm the strategy, since a USDC vault can mean very different risk depending on the platform.
​

On October 6, 2026, DeFiLlama listed Kamino USDC markets paying 2.67% to 5.82% with about $31M of USDC across them. Walkthroughs: our Kamino guide and stablecoin vaults explained.
​

Maple lends USDC to vetted crypto firms such as market makers and trading desks, screened by its own credit team. That is credit risk rather than overcollateralized lending: if a borrower defaults, depositors can take losses. In exchange, syrupUSDC has paid the highest rate among the large USDC pools.
​

Per DeFiLlama on October 6, 2026, Maple's syrupUSDC paid 5.18% on Ethereum with $2.9B of TVL, the largest single USDC lending pool in the table. Check the Maple app for current withdrawal terms before depositing.
​

Sky, formerly MakerDAO, pays the Sky Savings Rate on sUSDS. USDC holders convert to USDS one for one through Sky's swap module, then deposit to sUSDS. There is no KYC and no lockup. The trade-off is that you hold USDS, not USDC, and its backing is set by Sky governance votes.
​

Per DeFiLlama on October 6, 2026, sUSDS paid 3.60% with $4.8B of TVL on Ethereum, the largest venue in this table. Our sUSDS guide covers the conversion flow and risks.
​

sUSDe is staked USDe, Ethena's synthetic dollar, which earns from hedged perpetual futures positions. When funding rates fall, the yield falls with them. Unstaking has a cooldown, so you cannot exit instantly, and Ethena does not offer sUSDe to US persons. It is USDC-adjacent, not USDC.
​

Per DeFiLlama on October 6, 2026, sUSDe paid 4.96% with $1.2B of TVL, below Maple and close to plain lending rates. At that spread the funding-rate and cooldown risks are harder to justify. See our yield aggregators guide for alternatives.
​

Tokenized Treasury funds pay short-term US government debt yield onchain, and USDC is the usual on-ramp. This is the closest thing to USDC that pays interest without DeFi or funding-rate risk. Most require KYC: BUIDL and OUSG serve institutions, while USDY targets eligible non-US users.
​

Per RWA XYZ, BlackRock's BUIDL held $2.2B with a 30-day APY of 3.60% and a $5M minimum. See our BUIDL explainer and tokenized Treasuries guide for access rules.
​

Coinbase pays USDC rewards on balances held in a Coinbase account. It is the simplest route: no wallet, no gas, no bridge. The rate is set by Coinbase and can change, and the program is custodial, so you rely on Coinbase rather than a smart contract. Eligibility depends on location.
​

Per Coinbase, the posted rate is 3.75%, rewards are paid weekly, there is no lockup, and the program is exclusive to Coinbase One members, with plans starting at $4.99 a month. Factor the membership cost into small balances.
​

US users lose some routes. sUSDe is not offered to US persons, tokenized Treasury funds mostly require accreditation or institutional onboarding, and Coinbase Rewards needs a Coinbase One plan. Non-US users get a wider menu but should check local rules such as MiCA in the EU. None of these routes is FDIC-insured.
​

A clean US retail stack on October 6, 2026: Coinbase Rewards at 3.75% per Coinbase for custodial cash, plus Aave or Fluid for a self-custodial slice at 4.60% to 4.83% per DeFiLlama.
​

The best USDC rate is often on a different chain from where your USDC sits. Eco Routes lets a treasury or app request USDC on a target chain, such as Solana for Kamino, and sources it from Base, Arbitrum, or Ethereum in one call, removing the manual bridge step when rebalancing between venues.
​

Sources and methodology. APY and TVL figures come from DeFiLlama yield data pulled October 6, 2026. The Coinbase rate is from Coinbase. BUIDL figures are from RWA XYZ. Rates refresh continuously, so check live before depositing.
