Specification

PoolInstance3_2

Extends PoolInstance contract, and includes custom initialization for the stable debt off-boarding.

The logic of the custom initialization is:

  currentReserve.__deprecatedStableDebtTokenAddress = address(0);

This makes sure that the __deprecatedStableDebtTokenAddress points to address(0) and also the __deprecatedStableBorrowRate is 0

For L2s instances, an additional L2PoolInstance3_2 is included, introducing the L2PoolInstance contract in the inheritance chain.

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.
• Deploys new InterestRateStrategy contract and updates interest rates from the previous strategy contract and sets them on the new one.
• Migrates all assets currently in eMode to be both borrowable & collateral in eMode
