Aave has activated borrower incentives for USDC in its V4 Core Hub on Ethereum, giving borrowers 2% back in USDC rewards on the total amount borrowed against eligible collateral. The program ranks among the first large-scale incentive initiatives within Aave V4, which launched a few months ago with a "hub-and-spoke architecture." It also continues a broader industry pattern in DeFi lending, where protocols have used borrower rebates and liquidity mining to attract stablecoin demand — a competitive dynamic that has intensified as major lending platforms vie for market share.

Under this design, liquidity is centralized in the Core Hub, while the spoke components handle different types of collateral and their associated risk parameters. Incentives are once again available on Ethereum Mainnet. To participate, borrowers must supply any of the supported collateral assets before borrowing USDC, making them among the first users to benefit from these rebates.

How the Program Works

According to Aave's documentation, incentives are distributed through the incentive controller, a system module that dispenses either AAVE tokens or USDC. These rewards may be funded directly from the Aave DAO treasury or sourced from an external partner such as Circle, the issuer of USDC. Such partnerships, where a stablecoin issuer subsidizes usage of its asset within DeFi protocols, are an established mechanism for expanding a stablecoin's on-chain circulation.

The initiative closely mirrors — or possibly scales up — the earlier Merit programs on Base and V3 that offered borrowing discounts, and it now targets the deployment of V4 on the primary Ethereum chain.

Relevance to DeFi Lending

According to DeFiLlama, Aave remains the leading DeFi lending platform with more than $30 billion in total value locked (TVL), competing against Compound, Morpho, and Spark. With stablecoin borrow APRs fluctuating, a 2% rebate effectively reduces the net borrowing cost and could lift USDC utilization. In general, higher utilization drives higher supply APY, which benefits lenders and serves as a test of whether protocol revenue is sufficient to cover the incentive expenditure.

Migration and Monitoring

Interest rates in V4 will vary by collateral risk, with WETH borrowing rates priced lower than those for more volatile assets. The incentive is expected to encourage V4 adoption and prompt liquidity to migrate from V3.

The DAO will also monitor the USDC interest rate, utilization levels, and the costs incurred by the DAO treasury as the program proceeds. Observers can track these metrics, along with V4 TVL growth relative to V3, through public dashboards and governance forums as the program unfolds.
