Diamond Proxy Pattern

Overview

The Diamond Proxy Pattern is a comprehensive implementation of the diamond proxy architecture. This pattern allows developers to deploy upgradeable contracts efficiently and manage multiple facets of a contract seamlessly. The project includes a factory for deploying beacon proxies and upgrading them across multiple deployments. For example it can be used by a pool factory in an AMM to upgrade multiple pools at once.

Features

• Upgradeable Contracts: Implements OpenZeppelin's UpgradeableBeacon for managing logic upgrades.
• Scalable Deployment: Deploy and manage thousands of proxies efficiently with a single beacon.
• Customizable: Provides flexibility for adapting to specific use cases.

Prerequisites

This project depends on OpenZeppelin's BeaconProxy and UpgradeableBeacon contracts. Ensure you have the following dependency installed:

$bash npm install @openzeppelin/contracts $

Installation

To install this repository as a package:

$bash npm install diamond-proxy-pattern $

Example Usage

Deploying the Factory

1. Deploy the Factory contract by providing the address of your logic contract: $solidity constructor(address _logic) $

2. Use the deployPool() function to create a new proxy. Each proxy will share the same logic contract.

Upgrading the Logic Contract

To upgrade all deployed proxies, call the updateBeaconLogic(address newLogic) function with the new logic contract's address. This updates the beacon to point to the new implementation.

Contract Structure

Factory.sol

The factory contract provides functionality to:

• Deploy beacon proxies
• Manage multiple proxies
• Upgrade the logic contract across all proxies

BeaconProxyManager.sol

Handles the creation and management of the beacon used for proxies. This contract abstracts away the complexities of beacon management.

Examples

Deploy a New Proxy

$solidity address newProxy = factory.deployPool(); $

Upgrade All Proxies

$solidity factory.updateBeaconLogic(newLogicAddress); $

Retrieve All Proxies

$solidity address[] memory allProxies = factory.getPoolsCount(); $
