Obtain the administration address for a proxy deployment of transparent upgrade with Oz
As developers, we are still looking for ways to improve our decentralized applications (DAPP) and make them more secure and transparent. Such a way consists in implementing a transparent modular proxy architecture using Ethereum blockchain. In this article, we will explain how to obtain the administration of the proxy contract deployed from the manufacturer of version 5 of the OZ.
Background
Before diving into the solution, it is essential to understand the context of Oz and its version. OZ (optimized areas) is a protocol designed for decentralized applications which allows developers to create a complex logic in addition to Ethereum without worrying about the problems of scalability and performance. One of the main characteristics of OZ is its ability to deploy intelligent contracts transparently, which means that no additional gas is spent or that network waste occurs.
Deployment of the administration contract with Oz version 5
In version 5 of the OZ, the administration contract is deployed from the manufacturer of the proxy contract using a specific event mechanism. To obtain the administration address, you must understand how it works. Here is a step by step guide:
- Create a new OZ project: Start by creating a new OZ project or cloning an existing project.
- Create the proxy contract : Create a new contract that will serve as a proxy for your application. This contract must be responsible for the management of incoming requests and delegation to other contracts.
- implement the manufacturer
: In the manufacturer of the proxy contract, deploy the administration contract using the
Deployctract 'method. This method takes two arguments: the name of the deployment contract (admin ') and a table of accounts that will have access to the contract methods ([]’).
- Get the administration address in the deployment transaction : During the deployment transaction of the proxy contract, obtain the administration address by listening to the event `
Deployedadmin 'issued when the contract 'Administration is deployed.
- Configuration of management events : In the main contract of your application (the one that will execute the proxy), configure an event manager to listen to the eventDeployedadmin ‘.
Here is an example of code in Solide to demonstrate it:
`Solidity
Pragma Solidity ^ 0.8,0;
Import "
Import "
Proxycontact contract {
Use of meters for meters. COURTER;
approach private administration;
Builder () {
Make Deployedadmin (0);
Administration = 0;
}
Getadminaddress function () Returns of public view (address) {
Return Administration;
}
}
'
How it works
When the proxy contract is deployed, it issues a "deployedadmin" event with the address of the newly deployed administration contract. In the main contract of your application, you can listen to this event and configure an event manager to update theAdministndress' variable.
Solidity
Contract contract {
Getadminaddress function () Returns of public view (address) {
require (block.timestamp> Now, "the proxy contract is not yet deployed");
Return Administration;
}
}
` ‘
Conclusion
By following these steps and including how to deploy an administration contract with Oz version 5, you can take advantage of the transparent upgrade proxy architecture. This approach provides a secure and evolutionary means of creating a complex logic above Ethereum without sacrificing performance or scalability.
Note: This is only a basic example and may need to be adapted to your specific use case.
