Reserve Factor Updates Mid July
01Summary
This proposal adjusts interest rate parameters across Aave v2 and v3 to incentivize migration to v3 and native USDC. Specifically: increasing Slope1 by 75bps on Polygon v2, increasing Reserve Factor by 5% on Ethereum v2 and Avalanche v2, and increasing Reserve Factor by 5% for bridged USDC.e and USDbC on Arbitrum, Optimism, Polygon, and Base.

- parameter change
Key changes
- Increase Slope1 parameter by 75bps on Polygon v2 for DAI, USDT, USDC (11.25% to 12.00%), wBTC, wETH (6.25% to 7.00%), and wMATIC (8.25% to 9.00%)(high)
- Increase Reserve Factor by 5% on Ethereum v2 for DAI, USDC, USDT (60% to 65%), wETH (60% to 65%), LINK (65% to 70%), and wBTC (65% to 70%)(high)
- Increase Reserve Factor by 5% on Avalanche v2 for DAI.e, USDC.e, USDT.e, wAVAX, wETH.e (55% to 60%) and wBTC.e (60% to 65%)(high)
- Increase Reserve Factor by 5% on USDC.e across Arbitrum, Optimism, and Polygon (25% to 30%), and USDbC on Base (25% to 30%)(medium)
Notable concerns
- Deposit yields will decrease for affected assets on Ethereum v2 and Avalanche v2, which may impact user returns
- Borrowing costs increase on Polygon v2 due to Slope1 increase, reducing capital accessibility for borrowers
- Changes are designed to encourage migration away from v2 instances; users on v2 should monitor for alternative opportunities on v3

02Description
Simple Summary
This AIP shall implement the following parameter adjustments:
- Increase Slope1 across Polygon v2 by 75bps;
- Increase Reserve Factor (RF) on Ethereum v2 and Avalanche v2 by 5.00%; and,
- Increase USDC.e and USDbC RF by 5.00% on Arbitrum, Optimism, Polygon, and Base.
Motivation
This AIP will reduce deposit yield for assets on Ethereum v2 and Avalanche v2 instances of Aave Protocol by increasing the RF by 5.00%. By increasing the RF a greater portion of the interest paid by borrowers is directed to the Aave DAO's treasury.
This results in a lower deposit rate for users and encourages migration from v2 instances of the Aave Protocol to v3. User's funds are not at risk of liquidation and the borrowing rate remains unchanged.
The RF across all USDC.e and USDbC reserves will be increased by 5.00% to encourage migration from bridged USDC to native USDC on each respective network.
By increasing the Slope1 parameter by 75bps on Polygon v2, the cost of capital to users increases and further encourages migration to Polygon v3.

03Mismatch analysis
The decoded on-chain data consists of a single generic execute() call to a payload contract on Ethereum mainnet, with no further decoded sub-calls or parameters. This is the standard pattern used by Aave governance proposals, where a dedicated payload contract (referenced in the proposal's 'Implementation' links) contains the actual logic for updating Slope1 and Reserve Factor parameters across multiple markets and chains (Polygon v2, Ethereum v2, Avalanche v2, and v3 deployments on Arbitrum, Optimism, Polygon, and Base) via cross-chain governance bridges. Because the calldata here does not expose the individual parameter-setting calls (asset addresses, old/new RF or Slope1 values), it is not possible to directly verify each specific numeric claim in the description against on-chain values. However, there is nothing in the decoded action that contradicts the description, and the pattern (single execute() call routing to a payload contract) is consistent with how this type of multi-chain parameter-adjustment proposal is typically implemented. Given the lack of granular calldata detail, confidence in a full line-by-line verification is low, but no evidence of a discrepancy, extra action, or omitted action was found at the level of detail available. Therefore we assess the proposal as consistent, with low confidence due to insufficient decoded detail to confirm every individual parameter value matches the tables in the specification section.
