Module types
Veive is based on a modular structure that extends the functionalities of smart accounts on Koinos. The modules are divided into four main categories, each with a specific role in the ecosystem:
Validation Modules (mod-validation-as)
Description: These modules verify the authenticity and authorization of operations. They are crucial for ensuring that operations are performed according to the rules set by the user or system.
Functioning: Validation modules check operations against specific criteria, such as the validity of the signature or compliance with certain security policies. For example, a module might verify that a transaction is correctly signed and that the transferred amount does not exceed a certain limit.
Execution Modules (mod-execution-as)
Description: These modules are responsible for executing the requested operations. They can carry out a wide range of actions, from token transfers to calling specific smart contracts.
Functioning: Once an operation is validated, the execution modules complete the requested action. This can include sending tokens, interacting with other smart contracts, or executing application-specific logic.
Signature Modules (mod-sign-as)
Description: These provide alternative signing methods, separate from the validation logic. This allows for the use of different signing methods, such as ECDSA, WebAuthn, or other authentication mechanisms.
Functioning: Signature modules are invoked to validate the signatures of operations. Unlike validation modules, which focus on authorizing operations, signature modules handle the authentication method used to sign transactions.
Hooks Modules (mod-hooks-as)
Description: These modules perform actions before and after operations, offering greater flexibility in implementing additional controls and logic.
Functioning: Hooks modules can be used for preliminary checks, like additional security verifications, or post-operation actions, such as logging events or updating internal states.
