The official governance page shows that the Aave community has initiated the "GHO Cross-Chain - Part 1" proposal, and on-chain voting is now open until June 22.
The proposal proposes a cross-chain implementation of the GHO stablecoin (the native asset of the Aave protocol), first using the Chainlink Cross-Chain Interoperability Protocol (CCIP) to initially expand to the Arbitrum network.
This smart contract has been perfected through multiple stages of design, development, testing, and implementation. In terms of security verification, a partnership was established with DAO service providers Certora and BGD Labs for code review.
The proposal was split into two separate proposals, and after approval by the DAO, the second proposal (Part 2) will be released for configuring GHO on the Arbitrum Aave Pool, using the risk parameters established by Chaos Labs.
