The discussion revolved around a proposal by Gandalfthebrown to implement a custom protocol that leverages Wormhole's generic messaging for cross-chain communication and Hashflow's cross-chain DEX to facilitate collateral transfers when backing aTokens¹. Wormhole, a cross-chain interoperability protocol, and Hashflow, a decentralized exchange platform, were explained in detail, with their respective roles in the proposed protocol outlined¹.

The proposal also included conservative Portals minting caps for USDC, USDT, and ETH on all networks that Aave V3 is deployed on and Wormhole supports. A nominal fee would be charged to users for bridging their aTokens, with half of this fee going to the Aave DAO¹. The benefits to AaveDAO were also highlighted, emphasizing the importance of fostering multi-chain deployments for AaveDao's long-term success¹.

The discussion saw support from WintermuteGovernance, MarcZeller, and PennBlockchain, with suggestions for increasing the USDC mint cap to $1M and starting with a pilot program between L1 and Arbitrum and/or Optimism before expanding to other networks^2,3,4. Gandalfthebrown agreed with these suggestions and confirmed that they would be implemented⁵.

The proposal was then escalated to the snapshot phase by MarcZeller, with a vote scheduled to start the following day⁸. Despite some concerns about Wormhole's centralization and potential security risks, Lbsblockchain expressed support for the proposal and suggested the inclusion of an Insurance Fund to better align incentives between Aave and Wormhole/Hashflow⁹.

In conclusion, the proposal to implement a custom protocol using Wormhole and Hashflow to facilitate collateral transfers when backing aTokens received broad support from the community. The proposal is now in the snapshot phase, with a vote scheduled to determine its future.
