The Capability abstraction is used throughout the ConsenSys NFT platform. A capability is an array of JSON objects, containing the signatures of the related smart contract members (functions, events, etc.). A capability is associated with an Application Binary Interface (ABI).

Each time the platform interacts with a smart contract, it ensures that it has the required capabilities. This generic approach makes the platform compatible with a variety of smart contracts, even allowing users to bring their own custom contracts into the platform.

You can get the known capabilities ABIs from the public capabilities endpoint.
