AdoptLaw.sol

AdoptLaw.sol is an executive law that enables the adoption of new laws into the Powers protocol. It provides a mechanism to add new governance rules and functionality to the system.

Overview

This law provides a mechanism to:

• Adopt new laws into the protocol

• Configure law parameters

• Set up law conditions

• Track law adoption history

• Enforce adoption rules

Configuration

When adopting an AdoptLaw instance, no parameters are required. The law is designed to facilitate the adoption of other laws.

Usage

Proposing an Action

When calling the law, four parameters must be provided:

1. law (address): The address of the law contract to adopt

2. nameDescription (string): Name and description of the law

3. inputParams (bytes): Encoded input parameters for the law

4. conditions (bytes): Encoded conditions for the law

Execution Flow

1. Law Validation

   • Verifies the law contract address

   • Validates law parameters

   • Checks adoption conditions

2. Law Adoption

   • Adopts the new law

   • Configures law parameters

   • Sets up law conditions

3. State Management

   • Updates adoption history

   • Maintains law registry

   • Tracks law status

State Variables

struct Data {
    address[] adoptedLaws;     // List of adopted laws
    mapping(address => bool) isAdopted; // Adoption status
    mapping(address => uint256) adoptionTime; // When law was adopted
}

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 adoption tracking

• Initializes empty law registry

handleRequest

function handleRequest(
    address caller,
    address powers,
    uint16 lawId,
    bytes memory lawCalldata,

) public view virtual override returns (
    uint256 actionId,
    address[] memory targets,
    uint256[] memory values,
    bytes[] memory calldatas,
    bytes memory stateChange
)

• Processes the adoption request

• Validates law and parameters

• Prepares adoption data
