Payload reports


Technical analysis

We have verified that the payload activates v3.1 on all markets with the following:

  • The PoolConfigurator implementation is upgraded.

  • The Pool implementation is upgraded.

  • The Data Provider is upgraded.

  • All assets are updated with their most recent value which includes indexes and data rates

  • All assets except Ethereum GHO are being enabled to use virtualAccounting and initialized with their current virtualAccounting

  • All assets are receiving new intersetRateStrategy address which will be permanent instead of the current method where a new strategy is created each time there is an update to an immutable parameter in it.

  • All frozen assets with LTV != 0 will be updated such that the pendingLtv of each one will be updated to the current LTV and the LTV it self to 0.

  • On Avalanche the risk admin will be removed temporarily.


The proposal is consistent with the description on the governance forum.
