Create Modular Deployment System

Introduction

In the world of blockchain development, deploying smart contracts can be a complex and time-consuming process. To streamline this process, we can create a modular deployment system that allows users to easily deploy and configure their contracts. In this article, we will explore how to create a base script with a run function that can deploy an LST (Liquid Staking Token) and provide virtual methods for users to set the configuration.

Description

To create a modular deployment system, we need to start with a base script that has a run function. This function will be responsible for deploying the LST. We can take inspiration from existing code, such as the BaseRariDeploy.sol script from the Rari Capital GitHub repository.

Base Script with Run Function

// BaseScript.sol
pragma solidity ^0.8.0;

import "https://github.com/OpenZeppelin/openzeppelin-solidity/contracts/token/ERC20/SafeERC20.sol";

contract BaseScript {
    // Virtual method to set the LST token address
    function setLSTTokenAddress(address _lstTokenAddress) public virtual;

    // Virtual method to set the staking token address
    function setStakingTokenAddress(address _stakingTokenAddress) public virtual;

    // Virtual method to set the minimum stake required
    function setMinStakeRequired(uint256 _minStakeRequired) public virtual;

    // Run function to deploy the LST
    function run() public {
        // Check if the deployer has enough stake to burn
        if (msg.sender.balance < getMinStakeRequired()) {
            revert("Deployer does not have enough stake to burn");
        }

        // Deploy the LST
        // ...
    }

    // Get the minimum stake required
    function getMinStakeRequired() public view virtual returns (uint256);
}

In this base script, we have defined three virtual methods: setLSTTokenAddress, setStakingTokenAddress, and setMinStakeRequired. These methods allow users to set the configuration for the LST. We have also defined a run function that checks if the deployer has enough stake to burn and then deploys the LST.

Virtual Methods for Configuration

The virtual methods in the base script provide a way for users to set the configuration for the LST. These methods can be overridden by the user's contract to provide custom configuration.

// UserContract.sol
pragma solidity ^0.8.0;

import "BaseScript.sol";

contract UserContract is BaseScript {
    // Override the setLSTTokenAddress method
    function setLSTTokenAddress(address _lstTokenAddress) public override {
        // Set the LST token address
        lstTokenAddress = _lstTokenAddress;
    }

    // Override the setStakingTokenAddress method
    function setStakingTokenAddress(address _stakingTokenAddress) public override {
        // Set the staking token address
        stakingTokenAddress = _stakingTokenAddress;
    }

    // Override the setMinStakeRequired method
    function setMinStakeRequired(uint256 _minStakeRequired) public override {
        // Set the minimum stake required
        minStakeRequired = _minStakeRequired;
    }
}

In this example, the UserContract overrides the virtual methods in the BaseScript to provide custom configuration for the LST.

Testing the Base Contract

To ensure that the base contract is compatible with the staker modular deployment utilities, we need to test it thoroughly. We can write unit tests to verify that the base contract behaves as expected.

// BaseContractTest.sol
pragma solidity ^0.8.0;

import "BaseScript.sol";

contract BaseContractTest {
    // Test the run function
    function testRun() public {
        // Create a new instance of the base contract
        BaseScript baseContract = new BaseScript();

        // Set the LST token address
        baseContract.setLSTTokenAddress(address(0x1234567890abcdef));

        // Set the staking token address
        baseContract.setStakingTokenAddress(address(0x9876543210fedcba));

        // Set the minimum stake required
        baseContract.setMinStakeRequired(100);

        // Call the run function
        baseContract.run();
    }
}

In this example, we have written a test contract that creates a new instance of the base contract and calls the run function. We can then verify that the base contract behaves as expected.

Conclusion

In this article, we have explored how to create a modular deployment system for LSTs. We have defined a base script with a run function that can deploy an LST and provided virtual methods for users to set the configuration. We have also written unit tests to verify that the base contract behaves as expected. By following this approach, developers can create a modular deployment system that is easy to use and customize.

Future Work

In the future, we can improve the modular deployment system by adding more features and functionality. Some potential areas for improvement include:

  • Adding support for multiple LSTs
  • Providing a user interface for users to configure the LST
  • Integrating with other blockchain development tools and services

By continuing to improve and expand the modular deployment system, we can make it easier for developers to deploy and manage their LSTs.
