ExecutionContext

Git Source

Author: Euler Labs (https://www.eulerlabs.com/)

This library provides functions for managing the execution context in the Ethereum Vault Connector.

The execution context is a bit field that stores the following information:

- on behalf of account - an account on behalf of which the currently executed operation is being performed

- checks deferred flag - used to indicate whether checks are deferred

- checks in progress flag - used to indicate that the account/vault status checks are in progress. This flag is used to prevent re-entrancy.

- control collateral in progress flag - used to indicate that the control collateral is in progress. This flag is used to prevent re-entrancy.

- operator authenticated flag - used to indicate that the currently executed operation is being performed by the account operator

- simulation flag - used to indicate that the currently executed batch call is a simulation

- stamp - dummy value for optimization purposes
