The Managing adapter handles the proposal creation, sponsorship and processing of a new adapter/extension including its initial configuration, and permissions.

An adapter/extension can be added, removed or replaced in the DAO registry. In order to remove an adapter/extension one must pass the address 0x0 with the adapter/extension id that needs to be removed. To add a new adapter/extension one most provide the adapter/extension id, address and access flags. The address of the new adapter/extension can not be a reserved address, and the id must be a known id as defined in the DaoConstants.sol. The replace adapter/extension operation removes the adapter/extension from the registry based on the id parameter, and also adds a new adapter/extension using the same id but with a new address.

The Managing adapter also allows one set custom ACL flags to adapters that need to communicate with different extensions.


It is important to indicate which operation type will be performed. Set 1 to updateType when you are adding/removing an Adapter, and set 2 when you are adding/removing an Extension.


Submit a proposal and check:

  • if caller is an active member
  • if keys and values have equal length
  • if adapter/extension address is valid
  • if the access flags don't overflow
  • if adapter/extension address is not reserved

If all the requirements pass, then the proposal is subitted to registry and the adapter stores the proposal data.

Once the voting period ends, anyone can process the proposal. The proposal is processed only if:

  • it has not been processed already
  • the proposal has been sponsored
  • the voting has passed
  • the updateType is 1 (adapter) or 2 (extension)
  • the extension AclFlags, and address are valid

Access Flags#








  • adapterOrExtensionId: The id of the adapter/extension to add, remove or replace.
  • adapterOrExtensionAddr: The contract address of the adapter/extension.
  • flags: The DAO ACL for the new adapter.
  • keys: The configuration keys for the adapter.
  • values: The values to set for the adapter configuration.
  • extensionAddresses: The list of extension addresses that the adapter interacts with.
  • extensionAclFlags: The list of ACL flags that the adapter needs to interact with each extension.



All the proposals handled by the adapter per DAO.
