Inherits: Ownable, EIP712

Author: Mure

Factory contract for deploying applications as instances of the BeaconProxy contract within the Mure protocol.

Facilitates the secure and efficient deployment of upgradeable app contracts using the beacon proxy pattern. Implements the EIP-712 standard for signature validation and Ownable for access control. The factory contract relies on the MureConfig contract to verify EIP-712 signatures and manage the deployment process. Signatures are added with an expiry to enhance the security of the deployment process by ensuring that the provided signature is only valid within a certain time frame.

State Variables

beaconAddress

address public beaconAddress;

config

MureConfig public config;

DEPLOY_APP_HASH

Struct hash for validating app deployments keccak256("Deployment(string appName,string version,AppMember[] appMembers,uint256 nonce,uint256 deadline,address caller,string data)AppMember(address member,uint8 role)")

bytes32 private constant DEPLOY_APP_HASH = 0xe78e92e91ab6665af572917421100be08c66583917c23ae7a02b72bed7edc218;

nonces

Nonce mapping for signatures to prevent replay

mapping(address => uint256) public nonces;

Functions

constructor

constructor(address beaconAddress_, address config_, string memory name_, string memory version_)
    Ownable(msg.sender)
    EIP712(name_, version_);

deployAppProxy

Deploys an instance of the beacon proxy.

Requires signature for authorization.

function deployAppProxy(
    string calldata appName,
    string calldata version,
    AppMember[] calldata appMembers,
    uint256 deadline,
    string calldata data,
    bytes calldata sig
) external returns (address proxy);

Parameters

setBeaconAddress

Sets the beacon address for future proxy creation.

Can only be called by the contract owner.

function setBeaconAddress(address beaconAddress_) external onlyOwner;

Parameters

_hash

Generates a hashed representation of the app name, version, members, deadline, along with the sender's nonce.

function _hash(
    string calldata appName,
    string calldata version,
    AppMember[] calldata appMembers,
    uint256 deadline,
    string calldata data
) private view returns (bytes32);

Parameters

_hashAppMembers

Computes the keccak256 hash of an array of AppMember structs.

function _hashAppMembers(AppMember[] calldata appMembers) private pure returns (bytes32);

Parameters

_extractAppRoles

Extracts and categorizes members into admins and operators based on their roles.

function _extractAppRoles(AppMember[] calldata appMembers) private pure returns (address[] memory, address[] memory);

Parameters

_validateAdminRoleExists

Validates that there is at least one member with the DEFAULT_ADMIN role in the provided appMembers array.

function _validateAdminRoleExists(AppMember[] calldata appMembers) private pure returns (bool);

Parameters

Events

Deployment

event Deployment(
    string indexed appName, address[] appAdmins, address[] appOperators, address indexed appAddress, string data
);

BeaconUpdate

event BeaconUpdate(address indexed beaconAddress);
