Aave

Simple Summary

This proposal updates the bridge Hyperlane bridge adapters used on a.DI to connect Ethereum with Polygon, Avalanche, Binance and Gnosis to the new Hyperlane V3 version. Additionally, removes old native bridges on Optimism, Base, Arbitrum, Scroll and Metis, after verifying that the new active versions work properly.

Motivation

The main motivation of this proposal is to bring the Hyperlane bridge adapters to the up to date version (V3).

Specification

Updates the Hyperlane bridge adapters used to connect between networks to Hyperlane V3 and it also adds Adapter Name to the contracts to make it easy to track off chain

Network	Hyperlane
Ethereum	0x01dcb90Cf13b82Cde4A0BAcC655585a83Af3cCC1
Polygon	0x3e72665008dC237bdd91C04C10782Ed1987a4019
Avalanche	0x617332a777780F546261247F621051d0b98975Eb
Binance	0x3F006299eC88985c18E6e885EeA29A49eC579882
Gnosis	0xA806DA549FcB2B4912a7dFFE4c1aA7A1ed0Bd5C9

To add the new forwarder adapters the method function enableBridgeAdapters(ForwarderBridgeAdapterConfigInput[] memory bridgeAdapters) external will be used, and to remove the old forwarder adapters, the method function disableBridgeAdapters(BridgeAdapterToDisable[] memory bridgeAdapters) external will be called on each CrossChainController.

To add the new receiver adapters the method function allowReceiverBridgeAdapters(ReceiverBridgeAdapterConfigInput[] memory bridgeAdaptersInput) external will be used, and to remove the old receiver adapters, the method function disallowReceiverBridgeAdapters(ReceiverBridgeAdapterConfigInput[] memory bridgeAdaptersInput) external will be called on each CrossChainController.

The old native receiver bridge adapters to remove are:

Network	Native adapters
Arbitrum	0x3829943c53F2d00e20B58475aF19716724bF90Ba
Base	0x7b62461a3570c6AC8a9f8330421576e417B71EE7
Metis	0x746c675dAB49Bcd5BB9Dc85161f2d7Eb435009bf
Optimism	0x81d32B36380e6266e1BDd490eAC56cdB300afBe0
Scroll	0x118DFD5418890c0332042ab05173Db4A2C1d283c

Code diffs for the different networks can be checked on a.DI diff repository for revision 2. Adapter diffs: HLAdapter, BaseAdapter, IBaseAdapter
