Aave v3.3 upgrade

This repository contains contracts to upgrade existing instances of Aave protocol from v3.2.0 to v3.3.0.

Dependencies

• Foundry, how-to install (we recommend also update to the last version with foundryup).
• ZkSync Foundry, how-to install (we recommend also update to the last version with foundryup-zksync).

Setup

cp .env.example .env # you need to setup functional rpcs
forge install

# optional, to install prettier
yarn install

Tests

Command run test for all networks expect zkSync: forge test

Command to run test for zkSync: FOUNDRY_PROFILE=zksync forge test --zksync

There are two test templates available:

• PureTestTemplate.t.sol which creates a instance of the v3.3 protocol on a pure anvil
• UpgradeTestTemplate.t.sol which upgrades a existing protocol instance from 3.2 to 3.3

Upgrade payload

The payload for the upgrade does the following:

• Upgrades the PoolConfigurator implementation.
• Upgrades the Pool implementation.
• Connects the new PoolDataProvider to the PoolAddressesProvider.

Misc

Additionally, there are new versions of some periphery-contracts that might be deployed alongside the proposal, namely:

• WrappedTokenGatewayV3
• ParaswapAdapters
• StataTokenFactory

It's important to note that these contracts are:

• not part of the upgrade payload.
• they don't need to be upgraded, the old versions are perfectly operational.

Using the newer versions will result in slightly lower gas usage on certain operations.
