Technical analysis

Like on every Aave cross-chain proposal, this one follows the procedure defined on https://github.com/bgd-labs/aave-v3-crosschain-listing-template. This means that after execution on Ethereum, the proposal payload will be queued on the Polygon side of the cross-chain infrastructure and, after the timelock there, will be open for execution.

Assuming that the cross-chain flow works properly, we have verified from a technical perspective that the payload will effectively freeze the following assets, by calling freezeReserve() on the Aave v2 Polygon Configurator:

• BAL
• CRV
• DPI
• GHST
• LINK
• SUSHI

BGD validations

✅ The code on the proposal payload corresponds to the proposal specification.

✅ Only one payload used via delegatecall

✅ BGD reviewed the payload before the proposal was submitted.

❓ The proposal includes a proper tests suite, checking all necessary post-conditions.

✅ BGD reviewed the procedure followed to submit the proposal.
