Governor_ExecuteProposal

Governor_ExecuteProposal is an executive mandate that enables the execution of governance proposals on a configured Governor contract. It provides a mechanism to execute proposals that have succeeded in the governance process.

Overview

This mandate provides a mechanism to:

• Execute governance proposals that have succeeded
• Validate proposal state before execution
• Execute proposal actions directly
• Integrate with standard governance frameworks
• Track proposal execution

Configuration

When adopting a Governor_ExecuteProposal instance, one parameter must be provided:

1. governorContract (address): The address of the Governor contract to execute proposals on

Usage

Proposing an Action

When calling the mandate, four parameters must be provided:

1. targets (address[]): Array of target contract addresses for the proposal
2. values (uint256[]): Array of ETH values to send with each call
3. calldatas (bytes[]): Array of encoded function call data
4. description (string): Human-readable description of the proposal

Execution Flow

1. Parameter Validation

   • Verifies governor contract is configured
   • Validates proposal parameters
   • Checks array length consistency
   • Ensures description is not empty

2. Proposal Validation

   • Gets proposal ID from governor contract
   • Validates proposal exists
   • Checks proposal state is “Succeeded”
   • Ensures proposal is ready for execution

3. Proposal Execution

   • Returns proposal actions for direct execution
   • Bypasses governor contract execution
   • Executes actions directly

4. State Management

   • Records proposal execution
   • Updates governance state
   • Tracks execution history

Functions

initializeMandate

function initializeMandate(
    uint16 index,
    string memory nameDescription,
    bytes memory inputParams,
    bytes memory config
) public override

• Initializes mandate with configuration parameters
• Sets up Governor contract address
• Configures proposal execution parameters

handleRequest

function handleRequest(
    address caller,
    address powers,
    uint16 mandateId,
    bytes memory mandateCalldata,
    uint256 nonce
) public view virtual override returns (
    uint256 actionId,
    address[] memory targets,
    uint256[] memory values,
    bytes[] memory calldatas
)

• Processes the proposal execution request
• Validates proposal parameters and state
• Prepares proposal actions for execution
• Returns execution data

Error Conditions

1. Configuration Errors

   • “Governor_ExecuteProposal: Governor contract not configured”
   • Invalid governor contract address

2. Parameter Errors

   • “Governor_ExecuteProposal: No targets provided”
   • “Governor_ExecuteProposal: Targets and values length mismatch”
   • “Governor_ExecuteProposal: Targets and calldatas length mismatch”
   • “Governor_ExecuteProposal: Description cannot be empty”

3. Proposal Errors

   • “Governor_ExecuteProposal: Proposal not found”
   • “Governor_ExecuteProposal: Proposal not succeeded”
   • Invalid proposal state

4. Validation Errors

   • Zero address governor contract
