[AAVE] Onboard PT sUSDe July and PT eUSDe May on Core Instance

Simple Summary

This proposal seeks to onboard pendle PT-sUSDe-31July2025 and PT-eUSDe-29May2025 on the Aave V3 core instance and activate Edge AGRS system to automate updating eMode category params for these assets.

Motivation

Pendle allows users to split yield bearing tokens into principal (PT) and yield (YT) components. This opens the door to trading yield for the growing number of yield bearing tokens, and gives users additional options for yield farming strategies. A notable feature of the PT tokens is that at the maturity date, the value of the PT equals the value of the underlying asset and can be redeemed for the underlying. This means PT tokens, which can be bought at a discount within Pendle pools, represent the fixed rate part of a Pendle asset pair.

Pendle has seen extremely high growth this year, with current TVL of circa $4.5 billion. Along with this growth has come the desire for yield traders to borrow against their Pendle PT tokens. This represents a multi-billion dollar growth opportunity for Aave, without a large increase in risk if PT tokens are onboarded for already listed assets such as sUSDe. With this, it makes sense to onboard PT-sUSDe-31July2025 and PT-eUSDe-29May2025 assets.

The RiskSteward has been quite successful to update risk params in a controlled way in the past for rates, caps and other params. The new iteration of the RiskSteward allows to update eMode category collateral params such as LT, LTV and LB in a constrained manner, while also allowing to change the discountRate of pendle pt feeds. With this we activate the new RiskSteward on the core instance only for now, gradually migrating to newer RiskSteward on other instances as well.

Specification

The table below illustrates the configured risk parameters for PT_sUSDE_31JUL2025 and *PT_eUSDe_29MAR2025 assets:

| Parameter | PT_sUSDE_31JUL2025 | PT_eUSDe_29MAR2025 | |

The following EMode categories will be created for the assets listed:

PT-sUSDe Stablecoins E-Mode (id: 8):

| Asset | PT-sUSDe | USDC | USDT | USDS | | -- | -- |

• |
• |
• | | Collateral | Yes | No | No | No | | Borrowable | No | Yes | Yes | Yes | | LTV | 87.4% | - | - | - | | LT | 89.4% | - | - | - | | Liquidation Bonus | 4.6% | - | - | - |

PT-eUSDe Stablecoins E-Mode (id: 9):

| Asset | PT-eUSDe | USDC | USDT | USDS | | -- | -- |

The Pendle PT Capo with linear discount have been deployed with the following configurations:

| Parameter | PT_eUSDe_29MAR2025 | PT_sUSDE_31JUL2025 | |

• |
• |
• | | discountRatePerYear | 7.87% | 7.5124% | | maxDiscountRatePerYear | 39.22% | 21.22% |

We activate the next iteration of RiskSteward on core instance (audited by Certora), which allows updating the eMode category and the discount rate of pendle pt feeds. In addition we also activate the Edge AGRS system using a new instance of RiskSteward to a
