TUSD and BUSD Aave V2 Rate Amendments
01Summary
Reduce aggressive interest rates on TUSD and BUSD Aave V2 deprecated markets by lowering base rates from 100% to 10% and slopes to 0% to address bad debt accumulation concerns while maintaining the deprecation objective.
- Type
- parameter change
Key changes
- BUSD Base Rate reduced from 100% to 10%(high)
- BUSD Slope 1 reduced from 70% to 0%(high)
- BUSD Slope 2 reduced from 300% to 0%(high)
- TUSD Base Rate reduced from 100% to 10%(high)
- TUSD Slope 1 reduced from 70% to 0%(high)
- TUSD Slope 2 reduced from 300% to 0%(high)
Notable concerns
- Significant bad debt exists in both TUSD and BUSD markets that may not be resolved through debt repayment incentives at reduced rates
- High interest rates previously intended for market deprecation may have resulted in effective virtual debt growth rather than debt reduction
- Risk of debt escalation to arbitrarily high market size if rates remain at current aggressive levels

02Description
Simple Summary
Amend Interest Rate parameters for TUSD and BUSD Aave V2 deprecated markets.
Motivation
Currently, the highly aggressive interest rate strategy implemented for TUSD and BUSD markets, with the primary objective of deprecating, poses a challenge due to the distribution of bad debt within these markets.
Due to a significant amount of bad debt in these markets, the anticipated outcome of incentivizing debt repayments may not be realized to the same extent, alternatively resulting in effective virtual debt growth. Although the elevated reserve factor allows the collector to cover a substantial portion of the remaining aToken underlying claims of the respective market as other positions are repaid (provided the collector does not withdraw), this debt growth must be addressed. Otherwise, it could potentially escalate to an arbitrarily high market size, given the magnitude of the current interest rate.

03Mismatch analysis
The proposal follows the standard Aave governance execution pattern: the on-chain action is a single generic execute() call to a payload contract, which is typical for BGD Labs-authored Aave proposals. The actual parameter changes (interest rate strategy updates for TUSD and BUSD) are implemented inside that payload contract's bytecode and are not individually decoded in the calldata provided here. Because only the outer execute() call is visible, I cannot directly verify the specific numeric values (Base Rate 10%, Slope1 0%, Slope2 0%) claimed in the description against the calldata - this is a limitation of the available decoding rather than evidence of a mismatch. The proposal text is specific, detailed, and consistent with a legitimate BGD Labs risk parameter amendment proposal, and the referenced GitHub implementation link supports the described changes. Given the lack of decoded internal calls, I mark confidence as low since a full comparison isn't possible, but there is no visible sign of discrepancy, extra actions, or target mismatch in what is decoded, so I do not flag any specific issues. Delegates should verify the linked implementation contract's on-chain bytecode/simulation for exact parameter matching before voting, as is standard practice for these payload-based proposals.
