Installation

There are 2 ways: with Node.js and one Git Submodules

with Node

This is the recommended approach.

We assume that you already setup your working environment with hardhat + foundry as specified in foundry 's guide or hardhat 's guide and cd into it

cd my-project;

1. Add the redprint-forge using your favorite package manager, e.g., with Yarn:

yarn add -D redprint-forge

2. Adding remappings.txt with following line:

@redprint-core/=node_modules/redprint-forge/src
@redprint-deploy/=node_modules/redprint-forge/script
@redprint-forge-std/=node_modules/redprint-forge/lib/forge-std/src
@redprint-openzeppelin/=node_modules/redprint-forge/lib/openzeppelin-4_9_4/contracts
@redprint-openzeppelin-upgradable/=node_modules/redprint-forge/lib/openzeppelin-upgradable-4_9_4/contracts
@redprint-safe-contracts/=node_modules/redprint-forge/lib/safe-smart-account/contracts

[!TIP] We use @redprint-/ as a convention to avoid any naming conflicts with your previously installed libararies ( i.e. @redprint-forge-std/ vs @forge-std/)

What Is It For

One of our Swiss army knife toolset: redprint-forge is a developer-friendly framework/library in solidity to modify & deploy OPStack ’s contracts in a modular style.

The features include:

• Type-safe smart contract deployment

• Re-usable smart contract deployment and testing pipeline

• Standardized framework, minimizing developer mistake and enhancing better security

• All-Solidity-based so no context switching, no new scripting syntax in other languages

• Tx Management via Safe Smart Contract Deploy Script

Together with Redprint Wizard UI, which is a code generator/ interactive playground oriented for OPStack development, it does not only help novice developers to deploy OPStack's smart contracts to deploy on OP mainnet, but also help them to use generated deployment script in their own projects.

Quickstart

Tx Management Via Safe-Multisig

You can write solidity script, then execute it from command-line in order to make any smart contract calls, or send transactions from your own safe multi-sig wallet.

You can access both _upgradeAndCallViaSafe and _callViaSafe easily by inheriting and using from in redprint-forge module ’s parent contract SafeScript.

Call and Upgrade Proxy Contract

Let’s see a practical example when initializing one of OPStack's proxy contract ( eg. ProtocolVersions ) by calling _upgradeAndCallViaSafe:

/** ... */

// `redprint-forge` 's core engine
import { SafeScript} from "@redprint-deploy/safe-management/SafeScript.sol";

/** ... */

contract DeployAndInitializeProtocolVersionsScript is DeployScript, SafeScript {

    /** ... */

    function initializeProtocolVersions() public {
      console.log("Upgrading and initializing ProtocolVersions proxy");

      /** ... */

      address proxyAdmin = deployer.mustGetAddress("ProxyAdmin");
      address safe = deployer.mustGetAddress("SystemOwnerSafe");

      /** ... */

      _upgradeAndCallViaSafe({
          _proxyAdmin: proxyAdmin,
          _safe: safe,
          _owner: owner,
          _proxy: payable(protocolVersionsProxy),
          _implementation: protocolVersions,
          _innerCallData: abi.encodeCall(
              ProtocolVersions.initialize,
              (
                  finalSystemOwner,
                  ProtocolVersion.wrap(requiredProtocolVersion),
                  ProtocolVersion.wrap(recommendedProtocolVersion)
              )
          )
      });
      /** ... */
    }

}

[!NOTE] You can the full example here: 03B_DeployAndInitializeProtocolVersions.s.sol

Call to Any Contract with arbitrary data

Let’s see another example at SafeScript itselfs. Our internal function just calls _callViaSafe:

/** ... */

abstract contract SafeScript {

  /** ... */

  function _upgradeAndCallViaSafe( address _owner, address _proxyAdmin, address _safe, address _proxy, address _implementation, bytes memory _innerCallData) internal {

      bytes memory data =
          abi.encodeCall(ProxyAdmin.upgradeAndCall, (payable(_proxy), _implementation, _innerCallData));

      Safe safe = Safe(payable(_safe));
      _callViaSafe({ _safe: safe, _owner: _owner, _target: _proxyAdmin, _data: data });
  }

  /** ... */

}
