Deployment consists of implementation contract, ProxyAdmin and the proxy contract using OpenZeppelin Upgrades Plugins for Hardhat with a developer controlled private key. This means you should not be using these contracts in your OpenZeppelin Upgrades project. A multisig contract to control our upgradeable contract. An upgrade then involves the following steps: Send a transaction to the proxy that updates its implementation address to the new one. In this scenario, the proxy contract (TransparentUpgradeableProxy) is the wrapper for our implementation contract (V1), and if and when we need to upgrade our smart contract (via ProxyAdmin), we simply deploy another contract and have our proxy contract point to that contract, thus upgrading its state and future functionality. For UUPS and transparent proxies, use deployProxy and upgradeProxy as shown above. Here, the proxy is a simple contract that just delegates all calls to an implementation contract. A Defender guide on upgrading a smart contract in production secured by a multisig wallet, using Defender Admin and the Hardhat Upgrades plugin. Tomase: Kik Hernandez is a defensive upgrade from Bogaerts at short. Open all three contract addresses in three different tabs. I would refer to the admin as the owner of the contract that initiates the first upgrade. If a storage gap is not being reduced properly, you will see an error message indicating the expected size of the storage gap. If you dont know where to start we suggest to start with. Throughout this guide, we will learn: Why upgrades are important So whats happening here? To learn more about this limitation, head over to the Modifying Your Contracts guide. For beacons, deployBeacon and upgradeBeacon will both return an upgradable beacon instance that can be used with a beacon proxy. You just deployed an upgradeable smart contract and then upgraded it to include a new function. Execute the following lines in your terminal: @openzeppelin/hardhat-upgrades is the package that allows us to deploy our smart contracts in a way that allows them to be upgradeable. When Hardhat is run, it searches for the nearest hardhat.config file. Transactions require gas for execution, so make sure to have some ETH available. When working with upgradeable contracts using OpenZeppelin Upgrades, there are a few minor caveats to keep in mind when writing your Solidity code. To get started, youll need the following: A Defender account. Whilst this may be good enough for a local or testnet deployment, in production you need to better secure your contracts. Now that you know how to upgrade your smart contracts, and can iteratively develop your project, its time to take your project to testnet and to production! Smart contracts can be upgraded using a proxy. The required number of owners of the multisig need to approve and finally execute the upgrade. ), Update all contracts that interacted with the old contract to use the address of the new one, Reach out to all your users and convince them to start using the new deployment (and handle both contracts being used simultaneously, as users are slow to migrate). ETH to pay for transactions gas. Instead we need to first propose an upgrade that the owners of the multisig can review and once reviewed approve and execute the proposal to upgrade the contract. My old environment consisted of using Truffle for development along with the zos-cli environment and Basil. You will also need to have a few Mumbai Testnet MATIC in your account to deploy your contracts. Paste the following code into the file: After deploying the contract V1, we will be upgrading it to contract V2. Then, return to the original page. Migrations consist of JavaScript files and a special Migrations contract to track migrations on-chain. Our implementation contract, a ProxyAdmin and the proxy will be deployed. For a view of all contracts, you can check out my contracts at. At this point, you can open and view your folder in your code editor of choice. In this guide we will deploy to Rinkeby as Gnosis Safe supports Rinkeby testnet. When writing upgradeable contracts we need to use the Upgradeable version of OpenZeppelin Contracts, see: https://docs.openzeppelin.com/contracts/3.x/upgradeable, If you have an existing upgradeable project, then you can migrate from OpenZeppelin CLI to Upgrades Plugins using the following guide: https://docs.openzeppelin.com/upgrades-plugins/1.x/migrate-from-cli. The initializer function is provided to us by upgrades, and whatever function we pass to it will be executed only once at the time of the contract deployment. You can then execute the upgrade itself from the admin or owner address. You might have the same questions/thoughts as I had or even more. Create a scripts directory in our project root and then create the following deploy.js script in the scripts directory. Truffle Tests (in javascript, with Web3.js, Moralis.io and other test helper libraries). Transparent vs UUPS Proxies Explaining the differences between the Transparent Proxy Pattern and the newly available UUPS Proxies. For example, deployProxy does the following: Validate that the implementation is upgrade safe. Using the run command, we can deploy the Box contract to the development network. We also need to add our Defender Team API key to the exported configuration in hardhat.config.js: Our hardhat.config.js should then look as follows: Once we have setup our configuration we can propose the upgrade. Learn more about OpenZeppelin Contracts Upgradeable in Contracts: Using with Upgrades. However, for that, you need to verify the contract V2 beforehand. We can then copy and store our API Key and the Secret Key in our projects .env file. Upgrades Plugins Plugins for Hardhat and Truffle that abstract away the complexities of upgrades, while running automated security checks to ensure successful upgrades. The plugins include a prepareUpgrade function that will validate that the new implementation is upgrade-safe and compatible with the previous one, and deploy it using your local Ethereum account. This constructor serves the purpose of leaving the implementation contract in an initialized state, which is a mitigation against certain potential attacks. This is equivalent to setting these values in the constructor, and as such, will not work for upgradeable contracts. ERC721 NFT . 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. In this new file, paste the following code: Look back to contract V1 and see what the initialValue function does. This is because our proxy contract (e.g, TransparentUpgradeableProxy) has already been deployed, here we just deploy a new implementation contract (V2) and pass that to the proxy contract. by replacing This is often the case, but not always, and that is where the need for upgradeable smart contracts arises. As such, it is not allowed to use either selfdestruct or delegatecall in your contracts. Update: Resolved in pull request #201 and merged at commit 4004ebf. OpenZeppelin Hardhat Upgrades API Both deployProxy and upgradeProxy functions will return instances of ethers.js contracts, and require ethers.js contract factories as arguments. Now that we have a blank canvas to work on, let us get down to painting it. Along with using Defender Admin to better manage the upgrade process. Using the upgradeable smart contract approach, if there is an error, faulty logic or a missing feature in your contract, a developer has the option to upgrade this smart contract and deploy a new one to be used instead. 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. Hence, after deployment, the initial value of our variable will be 10. Keep in mind that the parameter passed to the. This means that if you have an initial contract that looks like this: Then you cannot change the type of a variable: Or change the order in which they are declared: Or introduce a new variable before existing ones: If you need to introduce a new variable, make sure you always do so at the end: Keep in mind that if you rename a variable, then it will keep the same value as before after upgrading. Calling upgradeProxy when using the plugin will run the storage gap validation checks as well, ensuring that developers using the OpenZeppelin Upgrades plugins can verify their contracts are upgrade-safe. Refer to how we tested Contract 1 and basically follow same logic. You can migrate to OpenZeppelin Upgrades Plugins to deploy and upgrade your upgradeable contracts. It usually takes a while to install them all. A subsequent update that adds a new variable will cause that variable to read the leftover value from the deleted one. Due to technical limitations, when you upgrade a contract to a new version you cannot change the storage layout of that contract. We can create a .env file to store our mnemonic and provider API key. 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. In summary, its best for the admin to be a dedicated account only used for its purpose which is obviously to be an admin. * * A security mechanism ensures that an upgrade does not turn off upgradeability accidentally, although this risk is * reinstated if the upgrade retains upgradeability but removes the security mechanism, e.g. You can decide to test this as well. Smart contracts deployed using OpenZeppelin Upgrades Plugins can be upgraded to modify their code, while preserving their address, state, and balance. 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. To see each individual contract, you can click the Contract Creation link under the To field on the Transactions tab. While learning how to upgrade contract you might find yourself in a situation of conflicting contracts on the local environment. Upgrade? We will be openzepplins hardhat-upgrades plugin. More info here, Lets write an upgradeable contract! Basically, there are two contracts: Contract 1 (proxy/point of access): This contract is a proxy or a wrapper that will be interacted with . On Ethereum, they may desire to alter a smart contract to fix a bug they found (which might even lead to a hacker stealing their funds! You can see that the value of the state variable of our contract has been stored as 10 over here, which shows that this is the smart contract responsible for maintaining our implementation contracts state. Thus, the proxy contract calls the appropriate function from the implementation contract on behalf of msg.sender, the end-user. We pass a couple of parameters to the deployProxy. 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). This means that if the caller is not an admin, the proxy contract will not even consider executing any sort of upgrade function. Report by Santiago Palladino, Lead Developer at OpenZeppelin A survey of the different Ethereum smart contract upgrade patterns and strategies from a technical viewpoint, plus a set of good practices and recommendations for upgrades management and governance. We can see the executed upgraded proposal in our list of proposals in Defender Admin and our contract has been upgraded. This comes to the end of this article. Upgradeable Contracts to build your contract using our Solidity components. If you need assistance with configuration, see Connecting to public test networks and Hardhat: Deploying to a live network. When installing OpenZeppelin Contracts (the latest version is 3.4, see: https://blog.openzeppelin.com/openzeppelin-contracts-3-4/) there is a Solidity 0.6 and a Solidity 0.7 version, as well as upgradeable versions of both. (See Advisor for guidance on multisig best practices). A delegate call is similar to a regular call, except that all code is executed in the context of the caller, not of the callee. We can simply get a free trial node from QuickNode, which is much better than investing time looking at different custom configs to launch your own node. Furthermore, we now have the decrease function too. Since these are internal, you must always define your own public initializer function and call the parent initializer of the contract you extend. In this guide we will use a Gnosis Safe but you could also use any supported multisig such as a legacy Gnosis MultiSigWallet. To install, simply run, In your hardhat.config file, you need to load it in, Your hardhat.config.js file should be similar to this, Contract 1 (contracts/Atm.sol) (proxy contract), In your contracts folder, create a new .sol file. If you accidentally mess up with your contracts storage layout, the Upgrades Plugins will warn you when you try to upgrade. The proxy admin contract also defines an owner address which has the rights to operate it. Copy the HTTP URL and paste it into the RPC_URL variable in your .env file. 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? 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. Call the ProxyAdmin to update the proxy contract to use the new implementation. Once you create them there is no way to alter them, effectively acting as an unbreakable contract among participants. Violating any of these storage layout restrictions will cause the upgraded version of the contract to have its storage values mixed up, and can lead to critical errors in your application. There is, however, an exception. Now create a new file in the contracts folder, named contractV1.sol, and paste the following code in the file: This contract is pretty simple. By separating the contract the user interacts with from the contract holding the contract's functionality, the code can effectively be "upgraded" by deploying a new implementation and pointing the proxy to that new address. We do NOT redeploy the proxy here. Block. upgradeProxy will create the following transactions: Deploy the implementation contract (our BoxV2 contract). upgrade() (queue)->->(execute)upgrade() Once you create them there is no way to alter them, effectively acting as an unbreakable contract among participants. Create another file in the contracts folder, and name it contractV2.sol. Make sure that all initial values are set in an initializer function as shown below; otherwise, any upgradeable instances will not have these fields set. Upgradeable contracts cannot have a constructor. Deploy upgradeable contracts. The hardhat-upgrades package is the plugin that allows us to call the function that deploys upgradeable contracts. The most popular development tools are Truffle and Hardhat (formerly Buidler). A ProxyAdmin to be the admin of the proxy. Before we upgrade our contract, remember to paste your proxy contract address (e.g, TransparentUpgradeableProxy address) in the variable UPGRADEABLE_PROXY above. You can get some at this faucet. The proxy is storing addresses of the logic . (see: https://docs.openzeppelin.com/learn/developing-smart-contracts#setting-up-a-solidity-project). We would normally test and then deploy to a local test network and manually interact with it. In this section, we will create two basic smart contracts. 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 section will be more theory-heavy than others: feel free to skip over it and return later if you are curious. You may want to uninstall the global version of OpenZeppelin CLI. Find all of our resources related to upgradeability below. To deploy our contract we will use a script. Go into the contracts folder, and delete the pre-existing Greeter.sol file. Powered by Discourse, best viewed with JavaScript enabled. If the direct call to the logic contract triggers a selfdestruct operation, then the logic contract will be destroyed, and all your contract instances will end up delegating all calls to an address without any code. We can then run the script on the Rinkeby network to propose the upgrade. Feel free to use the original terminal window youve initialized your project in. Go to your transparent proxy contract and try to read the value of number again. We then need to configure Hardhat to use our @openzeppelin/hardhat-upgrades plugin. Done! Happy building! Plugins for Hardhat and Truffle to deploy and manage upgradeable contracts on Ethereum. It has one state variable of type unsigned integer and two functions. OpenZeppelin Upgradeable Contracts A variant of the popular OpenZeppelin Contracts library, with all of the necessary changes specific to upgradeable contracts. Our globally distributed, auto-scaling, multi-cloud network will carry you from MVP all the way to enterprise. By default, only the address that originally deployed the contract has the rights to upgrade it. 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. 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. The State of Smart Contract Upgrades A survey of upgrade patterns, and good practices and recommendations for upgrades management and governance. Once a contract is created on the blockchain, there is no way to change it. How cool is that! Hardhatnpm install --save-dev hardhat2. Open the .env file and paste the following content: We'll fill in these empty variables in the following sections. 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. Manage proxy admin rights. A tutorial on using the UUPS proxy pattern: what the Solidity code should look like, and how to use the Upgrades Plugins with this new proxy pattern. To learn more about this and other caveats when writing upgradeable contracts, check out our Writing Upgradeable Contracts guide. expect((await atm.getBalance()).toString()).to.equal("0"); $ npx hardhat run --network localhost scripts/deploy-atm.js. I hope you are doing well! Only code is stored in the implementation contract itself, while the state is maintained by the TransparentUpgradeableProxy contract. With that in mind, here are the steps that we must complete to make a contract upgradable: First, we need to inherit an initializable contract. Do not leave an implementation contract uninitialized. Propose the upgrade. Deploy upgradeable contract. To learn how to access your private key, check out this short guide. It is also in charge of sending transactions to and fro the second contract that I would be talking about next. Multi Sig. 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. Click on Read as Proxy. See. We cannot make arbitrary changes to our contract, see, To test our upgrade we should create unit tests for the new implementation contract, along with creating higher level tests for testing interaction via the proxy, checking that state is maintained across upgrades. This flow chart will give you a better understanding: You may recall that the terminal returned us an address when we initially deployed our smart contract. Under the scripts folder, delete the sample-script.js file and create a new file named deployV1.js. Whenever you deploy a new contract using deployProxy in the OpenZeppelin Upgrades Plugins, that contract instance can be upgraded later. In the end, we did not actually alter the code in any of our smart contracts, yet from the users perspective, the main contract has been upgraded. You can change the proxy admin owner by calling the admin.transferProxyAdminOwnership function in the plugin. And this process is the same regardless of whether you are working on a local blockchain, a testnet, or the main network. How do I get the latest 3.4.0 version of OpenZeppelin running on my PC? This allows us to change the contract code, while preserving the state, balance, and address. The How. Thats it. It increases by 1, which means our function is being successfully called from the implementation contract. We can then deploy our upgradeable contract. npm install --save-dev @openzeppelin/hardhat-upgrades @nomiclabs/hardhat-ethers ethers, //Using alchemy because I intend to deploy on goerli testnet, an apikey is required. Are there any clean-up or uninstall operations I should do first to avoid conflicts? It is different from the deployment procedure we are used to. Overview Installation $ npm install @openzeppelin/contracts-upgradeable Usage Listed below are four patterns. We are now ready to configure our deployment tools. For the avoidance of doubt, this is separate from the version of OpenZeppelin Contracts that you use in your implementation contract. When we perform an upgrade, we deploy a new implementation contract and point the proxy contract to the new implementation. Transparent proxies include the upgrade and admin logic in the proxy itself. 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. We will use a multisig to control upgrades of our contract. Smart contracts are often called "immutable" which ensures that the code that developers are interacting with is tamper-proof and transparent. These come up when writing both the initial version of contract and the version well upgrade it to. If you are returned an address, that means the deployment was successful. PREFACE: Hello to Damien and the OpenZeppelin team. As a consequence, calling two of these init functions can potentially initialize the same contract twice. Refer to each plugin documentation for more details on the admin functions. Upgrades Plugins to deploy upgradeable contracts with automated security checks. Create and initialize the proxy contract. We will create a migration JavaScript to upgrade our Box contract to use BoxV2 using upgradeProxy. Why Upgrades?
