Optics is shaping the way we communicate across blockchains by facilitating seamless, cost-effective message transfers. In this guide, we’ll walk you through the practical steps to successfully integrate with Optics, with a few troubleshooting tips along the way. Let’s get started!

Understanding the Basics of Optics

Consider Optics as a delivery service connecting two different cities (blockchains). Despite being separate locations, this service efficiently transfers packages (messages) without needing to check the details of each package every time—making it cheaper and quicker. It establishes channels between these cities, enabling any application within to easily send and receive messages.

Key Components for Integration

To integrate with Optics, you’ll need several essential components:

• Home and Replica Contracts: These contracts manage communication channels and will be used by your xApp (cross-chain application).
• XAppConnectionManager: This contract connects your xApp to Optics, allowing enrollment and management of Home and Replica contracts.
• Message Library: Defining a message specification is crucial, as Optics sends raw byte arrays between chains.
• Router Contract: Acts as a translator between the Optics message format and the local chain’s call contract.

Getting Started with Your Integration

Here’s how you can seamlessly start using Optics:

1. Set Up Your Environment:
   • Install required dependencies for Solidity and set up your .env files.
   • Run the respective commands to install any packages, as shown below:

   cd solidity/optics-core
   npm i
   cd ../optics-xapps
   npm i

2. Configure Pre-commit Hooks:
   • Ensure commit signature verification and configure pre-commit hooks for added security as follows:

   echo .pre-commit.sh > .githooks/pre-commit
   chmod +x .githooks/pre-commit

3. Run a Watching Daemon:
   • A watcher daemon is essential for maintaining proper connections and protecting against fraud in the xApp’s operations. Always run one!

Building Agent Images

Utilize Docker to build agent binaries for production:

cd rust
./build.sh
./image_tag.release.sh

Commit Signature Verification

Ensure your commits are signed locally for contributing to Optics. Check out commit signature verification documentation for instructions.

Troubleshooting Tips

If you encounter issues during the integration process, consider these tips:

• Double-check the configurations in your .env files for any discrepancies.
• Ensure all dependencies are properly installed without errors.
• Run your watcher daemon if you’ve skipped it; failure to do so may cause communication failures.
