Simple Summary
This proposal allows the Aave governance to activate the Aave V3 Scroll pool (3.0.2) by completing all the initial setup and listing WETH, USDC, wstETH as suggested by the risk service providers engaged with the DAO (Gauntlet and Chaos Labs) on the governance forum.
All the Aave Scroll V3 addresses can be found in the aave-address-book.
Motivation
All the governance procedures for the expansion of Aave v3 to Scroll have been finished, said:
- Positive signaling and approval regarding the expansion on the governance forum, temp check snapshot, and final snapshot.
- Positive technical evaluation done by BGD Labs of the Scroll chain network, as described in the forum in detail.
- Positive risk analysis and assets/parameters recommendation by the service providers Gauntlet and Chaos Labs.
Specification
The proposal will do the following:
- Set risk steward and freezing steward as the risk admin by executing
ACL_MANAGER.addRiskAdmin(). - Set the guardian address as the pool admin by executing
ACL_MANAGER.addPoolAdmin(). This is following the standard procedure of keeping pool admin on the Aave Guardian during the bootstrap period, for security. - List the following assets on Aave V3 Scroll: WETH, USDC, wstETH.
The table below illustrates the initial suggested risk parameters for each asset:
