Technical analysis

We have verified the proposal uses correctly the Aave cross-chain governance system in the parts communicating with Polygon and Arbitrum.

Regarding each payload, the changes applied are the following:

Polygon

• wstETH:

  • Supply cap: 1'800 wstETH -> 2'400 wstETH

• stMATIC:

  • Supply cap: 25'000'000 stMATIC -> 30'000'000 stMATIC

Arbitrum

• wstETH:
  • Supply cap: 4'650 wstETH -> 9'300 wstETH

The caps updates are aligned with those defined in the Aave governance forum.
