If your contract is going to be deployed with upgradeability, such as using the OpenZeppelin Upgrades Plugins, you will need to use the Upgrade Safe variant of OpenZeppelin Contracts. This means that if the caller is not an admin, the proxy contract will not even consider executing any sort of upgrade function. Using the link from propose-upgrade.js each member of our team can review the proposal in Defender. Transfer control of upgrades (ownership of the ProxyAdmin) to a multisig. This package adds functions to your Hardhat scripts so you can deploy and upgrade proxies for your contracts. Execute these two commands in your terminal: The first command, npm init -y, initializes an empty package.json file in your directory, while the second command installs Hardhat as a development dependency which allows you to set up an Ethereum development environment easily. Run these commands in your terminal to create the folder and navigate into it: Great! When Hardhat is run, it searches for the nearest hardhat.config file. You can change the proxy admin owner by calling the admin.transferProxyAdminOwnership function in the plugin. However, keep in mind that since its a regular function, you will need to manually call the initializers of all base contracts (if any). Prerequisite: knowledge of how to set up dev environment and how to write smart contracts. After a period of time, we decide that we want to add functionality to our contract. In this guide we dont have an initialize function so we will initialize state using the store function. Writing Upgradeable Contracts When working with upgradeable contracts using OpenZeppelin Upgrades, there are a few minor caveats to keep in mind when writing your Solidity code. Depends on ethers.js. Once the installation is complete, you should now have everything you need to develop, test and deploy smart contracts on the blockchain. Give yourselves a pat on the back. By default, only the address that originally deployed the contract has the rights to upgrade it. It follows all of the rules for Writing Upgradeable Contracts: constructors are replaced by initializer functions, state variables are initialized in initializer functions, and we additionally check for storage incompatibilities across minor versions. Finally, open your hardhat.config file, and replace the entire code with this: The first few lines we've used to import several libraries we'll need. Now refresh the webpage of your implementation contract (V1), and you should see a green checkmark there too. Take a look at what ERC20Upgradeable looks like in @openzeppelin/contracts-upgradeable: Whether using OpenZeppelin Contracts or another smart contract library, always make sure that the package is set up to handle upgradeable contracts. Initializers Therefore, we will also need a Smart Contract Admin proxy, so we are going to use the Transparent Upgradable Proxy OpenZeppelin implementation. The Hardhat Upgrades plugin provides a deployProxy function to deploy our upgradeable contract. Only code is stored in the implementation contract itself, while the state is maintained by the TransparentUpgradeableProxy contract. Upgrade our Box using the Upgrades Plugins. After verifying that you have the .env file name listed in your .gitignore, you can then push your code to GitHub without worries since you have no private data in your hardhat.config file. You may notice that every contract includes a state variable named __gap. Only the owner of the ProxyAdmin can upgrade our proxy. Well, thats because we need to tell the block explorer that the contract indeed is a proxy, even though the explorer usually already suspects it. We will name ours UpgradeableContracts, but you can call it anything you like. At this point, you can open and view your folder in your code editor of choice. Lastly, go into your MetaMask and copy the private key of one of your accounts. This is equivalent to setting these values in the constructor, and as such, will not work for upgradeable contracts. Note: the format of the files within the .openzeppelin folder is not compatible with those of the OpenZeppelin CLI. It has one state variable of type unsigned integer and two functions. We will save this file as migrations/4_upgrade_box.js. Contract 2 (logic contract): This contract contains the logic. OpenZeppelin Upgrades plugins for Hardhat/Truffle can help us getting these jobs done. Check out the flow chart below: Please note that the address of the user who calls a particular function (msg.sender) is critical here. We would normally test and then deploy to a local test network and manually interact with it. Transparent proxies include the upgrade and admin logic in the proxy itself. And it also allows us to change the code by just having the proxy delegate to a different implementation contract. This philosophy is beneficial to those interacting with smart contracts but not always to those writing them. Run this command in the terminal: Note, you'll need to input the V2 contract address in the command above. If you need assistance with configuration, see Connecting to public test networks and Hardhat: Deploying to a live network. deployProxy will create the following transactions: Deploy the implementation contract (our Box contract). Open the Mumbai Testnet explorer, and search for your account address. How to create an upgradeable smart contract using OpenZeppelin SDK | by Paulina Baszkiewicz | Coinmonks | Medium Write Sign up Sign In 500 Apologies, but something went wrong on our end. They have a library of modular, reusable, secure smart contracts for the Ethereum network, written in Solidity. Instead, we call the upgradeProxy function. Deploy the ProxyAdmin contract (the admin for our proxy). You just set up a smart contract development environment using Hardhat and installed additional dependencies that will allow us to deploy and verify upgradeable smart contracts. For the sake of the example, lets say we want to add a new feature: a function that increments the value stored in a new version of Box. Plugins for Hardhat and Truffle to deploy and manage upgradeable contracts on Ethereum. Fortunately, this limitation only affects state variables. ETH to pay for transactions gas. The function initialValue() simply sets the initial value of the variable, while the function increase() increments its value by 1. Are there any clean-up or uninstall operations I should do first to avoid conflicts? Truffle users will be able to write migrations that use the plugin to deploy or upgrade a contract, or manage proxy admin rights. Thanks to OpenZeppelin though, you can now deploy upgradeable contract systems with ease using the familiar Truffle tool suite! Note that this trick does not involve increased gas usage. Relating it to regular daily lives, two parties who have signed a contract can decide to change agreements, perhaps they have to remove some terms or add some more or fix mistakes. for meeting room upgrades of audio/visual equipment, and ongoing IT requirements. The required number of owners of the multisig need to approve and finally execute the upgrade. When deploying this contract, we will need to specify the initializer function name (only when the name is not the default of initialize) and provide the admin address that we want to use. The size of the __gap array is calculated so that the amount of storage used by a contract always adds up to the same number (in this case 50 storage slots). Keep in mind that the admin of a proxy can only upgrade it, but not interact with the implementation contract. A survey of upgrade patterns, and good practices and recommendations for upgrades management and governance. For this guide we will use Rinkeby ETH. BAE Systems will also deliver updates for the ship's Aegis combat . ERC-20 Token Txns. Thus, we don't need to build the proxy patterns ourselves. Find all of our resources related to upgradeability below. Since these are internal, you must always define your own public initializer function and call the parent initializer of the contract you extend. You can have multiple proxies using the same implementation contract, so you can save gas using this pattern if you plan to deploy multiple copies of the same contract. There you have it, check for your addresses on Goerli Explorer and verify it. In order to upgrade a contract like Box we need to first deploy it as an upgradeable contract, which is a different deployment procedure than weve seen so far. Due to technical limitations, when you upgrade a contract to a new version you cannot change the storage layout of that contract. Events. Create another file in the contracts folder, and name it contractV2.sol. If a storage gap is not being reduced properly, you will see an error message indicating the expected size of the storage gap. When you are doing openzeppelin --version you are getting the version of the OpenZeppelin CLI and not the version of OpenZeppelin Contracts that you have installed. Lets deploy our newly added contract with additional feature, we use the run command and deploy the AtmV2 contract to dev network. Kindly leave a comment. What version of OpenZeppelin Contracts (upgradeable) were you using previously? Confirm that you are in the project directory (e.g, UpgradeableContracts) and then run this command in your terminal: If you did everything correctly, the terminal should tell you that it has compiled two solidity files successfully. This means you should not be using these contracts in your OpenZeppelin Upgrades project. This release of OpenZeppelin Contracts includes a new UUPSUpgradeable contract that is used to implement the UUPS proxy pattern. Ignore the address the terminal returned to us for now, we will get back to it in a minute. JavaScript library for the OpenZeppelin smart contract platform Once you create them there is no way to alter them, effectively acting as an unbreakable contract among participants. Best of all, you don't need to do anything to activate the Solidity integrated SafeMath. Lines 13-16: We can now simply call our function main() which will run the logic in our function. It's worth mentioning that these restrictions have their roots in how the Ethereum VM works, and apply to all projects that work with upgradeable contracts, not just OpenZeppelin Upgrades. This means that, when using a contract with the OpenZeppelin Upgrades, you need to change its constructor into a regular function, typically named initialize, where you run all the setup logic: However, while Solidity ensures that a constructor is called only once in the lifetime of a contract, a regular function can be called many times. Once you create them there is no way to alter them, effectively acting as an unbreakable contract among participants. Let's begin to write and deploy an upgradeable smart contract. Hence, after deployment, the initial value of our variable will be 10. You may have noticed that we included a constructor as well as an initializer. Create propose-upgrade.js in the scripts directory with the following code. We will initialize our Box contract by calling store with the value 42. In this article, I would be simulating an atm/bank. Why Upgrades? Happy building! If you want to use the Upgrades Plugins for an existing OpenZeppelin CLI project, you can migrate using the guide. Save the files that you have been working with and navigate back to the terminal. Create a contracts directory in our project root and then create Box.sol in the contracts directory with the following Solidity code. Transactions require gas for execution, so make sure to have some ETH available. In this guide we will use a Gnosis Safe but you could also use any supported multisig such as a legacy Gnosis MultiSigWallet. You can get some at this faucet. To quickly verify the contract, run this command in the terminal: If you have named your files or contracts differently from us, edit that command accordingly. And how to upgrade your contracts to Solidity 0.8. Voila! Lines 3-5: We then create a function to deploy our V1 smart contract and then print a status message. To create an upgradeable contract, we need a proxy contract and an implementation contract (with an optional ProxyAdmin contract). Whilst this may be good enough for a local or testnet deployment, in production you need to better secure your contracts. How cool is that! If you dont know where to start we suggest to start with. First the variable that holds the contract we want to deploy then the value we want to set. Defender Admin supports Gnosis Safe and the legacy Gnosis MultiSigWallet. This means that the implementation contract does not maintain its own state and actually relies on the proxy contract for storage. We then need to configure Hardhat to use our @openzeppelin/hardhat-upgrades plugin. There is also an OpenZeppelin Upgrades: Step by Step Tutorial for Truffle and OpenZeppelin Upgrades: Step by Step Tutorial for Hardhat. Transparent vs UUPS Proxies Explaining the differences between the Transparent Proxy Pattern and the newly available UUPS Proxies. When I came across upgradeable contracts, I was taken aback a bit. We will need a new folder locally where our project for this tutorial will live. Do not leave an implementation contract uninitialized. Deploy a proxy admin for your project (if needed). You just deployed an upgradeable smart contract and then upgraded it to include a new function. It allows us to freely add new state variables in the future without compromising the storage compatibility with existing deployments. This allows you to roll out an upgrade or fix a bug without requesting your users to change anything on their end - they just keep interacting with the same address as always. UUPS and transparent proxies are upgraded individually, whereas any number of beacon proxies can be upgraded atomically at the same time by upgrading the beacon that they point to. When you create a new upgradeable contract instance, the OpenZeppelin Upgrades Plugins actually deploys three contracts: The contract you have written, which is known as the implementation contract containing the logic. Inside, paste the following code: There is just one change in this script as compared to our first one. Your script should look similar to this, Create a scripts/AtmProxyV2-test.js. Can anyone tell me the quick-start steps to migrate from the old way of using OpenZeppelin (zos-cli) to the new method of using plugins? Additionally, Hardhat will create a .env file and install the sample projects dependency (e.g., @nomiclabs/hardhat-waffle ethereum-waffle chai @nomiclabs/hardhat-ethers ethers). Upgrades Plugins are only a part of a comprehensive set of OpenZeppelin tools for deploying and securing upgradeable smart contracts. . Create and Deploy an Upgradeable Smart Contract, npx hardhat verify --contract "contracts/contractV1.sol:V1" --network mumbai, "Insert your proxy contract address here", npx hardhat run --network mumbai scripts/upgradeV1.js, npx hardhat verify --contract "contracts/contractV2.sol:V2" --network mumbai, Different Ways to Verify Your Smart Contract Code, Call Another Smart Contract From Your Solidity Code, Create a Smart Contract Factory in Solidity using Hardhat, Create and Deploy a Smart Contract With Hardhat, Setup Local Development Environment for Solidity, Create a Secure Smart Contract using Vyper, Write an Ethereum Smart Contract Using Solidity, Write an Ethereum Smart Contract Using Vyper, Integrate Your Svelte App with a Smart Contract, "An Introduction to Upgradeable Smart Contracts", Create an upgradeable smart contract using OpenZeppelins Plug-ins for Hardhat, Compile and deploy the contract on the Mumbai Testnet using Hardhat, Verify the contract using Polygonscan API, Upgrade the contract and verify the results, NPM (Node Package Manager) and Node.js (Version 16.15 recommended), MetaMask with the Polygon Mumbai Testnet selected (you can learn how to add the network to your wallet, MATIC tokens on Mumbai Testnet (you can get some at this, Knowledge of upgradeable smart contracts. You can change the contracts functions and events as you wish. Though depending on what version of OpenZeppelin Contracts you had previously used, you may not be able to upgrade versions due to changes with state variables. We will use the Hardhat console to interact with our upgraded Box contract. We can create a .env file to store our mnemonic and provider API key. To create a storage gap, declare a fixed-size array in the base contract with an initial number of slots. One last caveat, remember how we used a .env file to store our sensitive data? That is because, as of now, any user who wants to interact with our implementation contract will actually have to send their calls through the proxy contract. Boot your QuickNode in seconds and get access to 16+ different chains. Learn: Upgrading Smart Contracts A chapter about upgrades in our Learn series, a guided journey through smart contract development. For instance, in the following example, even if MyContract is deployed as upgradeable, the token contract created is not: If you would like the ERC20 instance to be upgradeable, the easiest way to achieve that is to simply accept an instance of that contract as a parameter, and inject it after creating it: When working with upgradeable smart contracts, you will always interact with the contract instance, and never with the underlying logic contract. To test upgradeable contracts we should create unit tests for the implementation contract, along with creating higher level tests for testing interaction via the proxy. Copy the HTTP URL and paste it into the RPC_URL variable in your .env file. Plugins for Hardhat and Truffle to deploy and manage upgradeable contracts on Ethereum. For more details on the different proxy patterns available, see the documentation for Proxies. Using the migrate command, we can deploy the Box contract to the development network. upgradeProxy will create the following transactions: Deploy the implementation contract (our BoxV2 contract). Now is the time to use our proxy/access point address. const proxyAddress = "YOUR_PROXY_ADDRESS_FROM_DEPLOYMENT"; atmV2 = await upgrades.upgradeProxy(atm.address, AtmV2); it("should get balance and addition correctly", async function () {, npx hardhat run --network localhost scripts/upgrade-atmV2.js, openzepplin proxy upgrade pattern docs page, https://docs.openzeppelin.com/upgrades-plugins/1.x/writing-upgradeable, Contract 1 (proxy/point of access): This contract is a proxy or a wrapper that will be interacted with directly. Development should include appropriate testing and auditing. The Contract Address 0x712209b20df5dbb99147c40b5428c1b933e3314c page allows users to view the source code, transactions, balances, and analytics for the contract . Migrations consist of JavaScript files and a special Migrations contract to track migrations on-chain. However note, if you changed any code in the implementation contract (e.g, V1), you'll need to verify it before you can continue. Well be using VScode and will continue running our commands in the embedded terminal. Through this command, we point to the exact code of the contract we want to verify and use the hardhat-etherscan package to send a verification request. In total, we received 16 My main question is what doc should I now follow to use the new toolkit to compile and deploy Solidity contracts using Truffle with the new ZOS plugins? Now, let us run this script in the terminal: What basically happened here is that we called the upgrade function inside the proxy admin contract. Now that we have a solid understanding of what's happening on the backend, let us return to our code and upgrade our contract! Smart contracts are often called "immutable" which ensures that the code that developers are interacting with is tamper-proof and transparent. It definitely calls for an upgrade. We hope to be able to implement safety checks for this in future versions of the Upgrades Plugins. Next, go to your profile on PolygonScan and navigate to the API KEYS tab. Once a contract is created on the blockchain, there is no way to change it. In this section, we will create two basic smart contracts. Development should include appropriate testing and auditing. Basically, there are two contracts: Contract 1 (proxy/point of access): This contract is a proxy or a wrapper that will be interacted with . As an example, lets write a new version of the Box contract with an initializer, storing the address of an admin who will be the only one allowed to change its contents. If you are starting from scratch, then you can choose to use either Truffle or Hardhat and create a new project. Read Transparent Proxies and Function Clashes for more info on this restriction. Feel free to use the original terminal window youve initialized your project in. Deploy the proxy contract and run any initializer function. Upgrading via Multisig A Defender guide on upgrading a smart contract in production secured by a multisig wallet, using Defender Admin and the Hardhat Upgrades plugin. Whenever you deploy a smart contract using the deployProxy function, OpenZeppelin deploys two additional contracts for you, namely TransparentUpgradeableProxy and ProxyAdmin. Powered by Discourse, best viewed with JavaScript enabled. Hardhat users will be able to write scripts that use the plugin to deploy or upgrade a contract, and manage proxy admin rights. The next section will teach you the best practices when it comes to deploying your contracts. Instead we would need to create a new Team API Key. We will create a migration JavaScript to upgrade our Box contract to use BoxV2 using upgradeProxy. When working with upgradeable contracts using OpenZeppelin Upgrades, there are a few minor caveats to keep in mind when writing your Solidity code. OpenZeppelin Contracts helps you minimize risk by using battle-tested libraries of smart contracts for Ethereum and other blockchains. Here, the proxy is a simple contract that just delegates all calls to an implementation contract. In this guide we will deploy to Rinkeby as Gnosis Safe supports Rinkeby testnet. Note that changing the proxy admin owner effectively transfers the power to upgrade any proxy in your whole project to the new owner, so use with care. In this tutorial, we will demonstrate exactly how this is done by creating and deploying an upgradeable smart contract from scratch using OpenZeppelin and Hardhat. We want to add a new feature to our contract, a simple feature which is to include an add function that adds 500 to our balance. The required number of owners of the multisig can approve the proposal and then finally execute to upgrade our contract. What document will help me best determine if my contracts are using state variables in a way that is incompatible with the newest versions? A free, fast, and reliable CDN for @openzeppelin/upgrades. Once you have transferred the rights to upgrade a proxy or beacon to another address, you can still use your local setup to validate and deploy the implementation contract. We are initializing that the start balance be 0. The fact that Sale seemed so outwardly pleased on Wednesday at least leaves option A in play. UUPS proxies rely on an _authorizeUpgrade function to be overridden to include access restriction to the upgrade mechanism, whereas beacon proxies are upgradable only by the owner of their corresponding beacon.
