📝 WalkthroughWalkthroughThis set of changes focuses on restructuring and clarifying the message-passing tutorial and related code. The tutorial content was reorganized for better usability, consolidating introductory sections into a collapsible "About this tutorial" block and introducing tabbed views to differentiate between Supersim and Devnet environments. Environment variable names were standardized for consistency across all files, affecting contract addresses and private keys. Setup instructions were enhanced, and commands were updated to reflect local execution and the new variable naming scheme. The Solidity contract's import paths were updated to use scoped package imports. In the TypeScript application files, environment variable references were changed to match the new naming convention, and some wallet client extension methods were commented out for clarity. Additionally, the word "Devs" was removed from the word list. No changes were made to the logic or exported interfaces of the code snippets. Sequence Diagram(s)sequenceDiagram

1-23: Frontmatter completeness and metadata validation
All required frontmatter fields for a tutorial are present and non-empty (title, lang, description, topic, personas, categories, content_type).
25-25: Import statement addition is correct
ImportingTabsfromnextra/componentsaligns with the new tabbed interface usage later in the tutorial.
88-92: Installation list consistency
The installation list under the first<Steps>block uses parallel structure and sentence case correctly. No changes needed.
95-98: Local Supersim binary invocation
Correctly uses./supersim --versionto reflect the local execution instructions.
112-118: Clarity of devnets skip instruction
The line “If you are using the devnets, just skip this step.” is clear and concise.
119-139: Tabbed network configuration
The<Tabs>component cleanly segregates Supersim and Devnet instructions. Tab titles (“Supersim”, “Devnets”) are in Title Case and match the import.
156-164: Devnet environment variable section
The Devnet tab correctly updates variable names (PRIVATE_KEY,USER_ADDRESS, etc.) and instructs users to derive their address.

Consider rephrasing to the imperative form and removing pronouns for consistency. For example:Skip this section when using devnets, as autoforwarding cannot be disabled on those networks.

25-25: Import Tabs for multi-environment instructions
Good catch adding theTabscomponent import to support switching between Supersim and Devnets.
38-69: Add collapsible 'About this tutorial' section
The new<details>block cleanly consolidates prerequisites, learning goals, environment setup, and tools. Headings and list items follow sentence case and use proper nouns correctly. This improves scannability and aligns with other tutorials’ structure.
90-92: Installation bullets are clear and accurate
The bullet points for Foundry and Supersim requirements are concise and follow sentence case. Nice work clarifying the optional Supersim dependency.
97-97: Prefix Supersim command with local invocation
Updating to./supersim --versionensures users run the local binary explicitly. This resolves common path issues.
111-118: Clarify Supersim vs Devnet startup
The instructions now correctly differentiate starting Supersim with autorelay and skipping that step on devnets. The prose is clear and actionable.
119-139: Implement tabbed views for network configurations
Using<Tabs>to separate Supersim and Devnets tables improves readability. Tab names are in title case, tables are well formatted, and links point to the correct endpoints.
143-153: Standardize environment variable snippets
The Supersim and Devnet export examples now use consistent variable names (PRIVATE_KEY,USER_ADDRESS,URL_CHAIN_A/B,INTEROP_BRIDGE). This matches the tutorial’s updated naming convention and avoids confusion.Also applies to: 156-165

Updatingsleepfrom 2 to 4 seconds accounts for cross-chain inclusion delays on both chains. The explanation below correctly describes the reason.
461-461: Export updated offchain environment variables
IncludingGREETER_A_ADDRESS,GREETER_B_ADDRESS, andPRIVATE_KEYensures the Node process has access to all required values.
483-488: Add symlink instructions for onchain ABIs
Linking the compiled JSON artifacts into the offchain repo is clear and accurate. Theln -scommands reflect the expected project structure.
Description
Various minor updates to conform to the standard in other tutorials, such as having a collapsible "about this tutorial" and running on the devnets as well as Supersim.
