This is a Solidity smart contract that enables authorized actors to call other contracts with specific parameters.

The main use case for the Restricted Executor contract is to allow more granularity on contracts with wide access controls, like an Ownable contract or an AccessControl contract with an admin role.

It supports four main roles:

• PROPOSER_ROLE: can create new operations
• CANCELLER_ROLE: can cancel existing operations
• AUTHORIZER_ROLE: can authorize operation execution
• UPGRADER_ROLE: can upgrade the contract

The contract can create new operations containing a single call or a batch of calls. Each call specifies a target contract, an ether amount to send along with the call, and an encoded payload for the target contract (an encoded function call). A salt is used to ensure unicity of the operation id.

The operation id is then used as a role administered by the AUTHORIZER_ROLE to authorize addresses execution permission.

This contract is licensed under the MIT license.
