UpgradeableProxyADFS

Overview

  1. Author

    Aneta Tsvetkova

  2. Notice

    Implements an upgradeable proxy for the Blocksense

    Aggregated Data Feed Store (ADFS) contract.

  3. Developer notes

    Non-management calls are delegated to the contract address stored in

    IMPLEMENTATION_SLOT, which is upgradeable by the admin stored in the

    ADMIN_SLOT.

    Storage layout:

    * Management space: [0 to 2**128-2**116)

    * ADFS data space: [2**128-2**116 to 2**160)

    This contract intentionally deviates from the EIP-1967 slot scheme.

    It was co-designed with ADFS to accommodate its custom low-level

    storage management requirements.

    Note that this deviation has implications on storage isolation and

    upgrade safety.
