PresetSingleAction.sol

PresetAction.sol is an executive law that enables the execution of a predefined set of function calls. It provides a mechanism to execute multiple actions in a specific order with fixed parameters.

Overview

This law provides a mechanism to:

• Execute multiple function calls in sequence

• Use predefined target contracts and functions

• Pass fixed parameters to the functions

• Track execution history

• Enforce execution rules

Configuration

When adopting a PresetAction instance, three parameters must be provided:

1. targets (address[]): Array of target contract addresses

2. values (uint256[]): Array of ETH values to send with each call

3. calldatas (bytes[]): Array of encoded function call data

Usage

Proposing an Action

When calling the law, no parameters are required. The law executes the predefined set of actions in the order they were configured.

Execution Flow

1. Configuration Validation

   • Verifies target addresses

   • Validates calldata formats

   • Checks execution conditions

2. Function Execution

   • Executes each function call in sequence

   • Sends ETH if values > 0

   • Maintains execution order

3. State Management

   • Records execution history

   • Updates execution state

   • Tracks function calls

State Variables

struct Data {
    address[] targets;    // Array of target contracts
    uint256[] values;     // Array of ETH values
    bytes[] calldatas;    // Array of function call data
}

mapping(bytes32 lawHash => Data) public data;

Functions

initializeLaw

function initializeLaw(
    uint16 index,
    string memory nameDescription,
    bytes memory inputParams,
    Conditions memory conditions,
    bytes memory config
) public override

• Initializes law with configuration parameters

• Sets up target contracts and functions

• Stores execution parameters

handleRequest

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

• Processes the execution request

• Validates configuration

• Prepares function calls

• Returns execution data

Error Conditions

1. Function Call Errors

   • "Invalid target"

   • "Invalid calldata"

   • "Function call failed"

2. Parameter Errors

   • "Invalid value"

   • "Invalid calldata format"

   • "Array length mismatch"

3. Validation Errors

   • Zero address target

   • Invalid calldata

   • Invalid value amount
