Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout. Please see our FAQ for further information. WalkthroughThe changes in this pull request include the addition of a new key-value pair in the JSON metadata file for SuperchainERC20 and the creation of a new documentation file detailing the deployment process for assets using the SuperchainERC20 standard. Additionally, the existing SuperchainERC20 documentation has been updated to include links to the new guide and a warning about interoperability requirements with the SuperchainERC20Bridge. Changes

1-5: Enhance the description metadata.The current description is somewhat redundant with the title. Consider making it more specific about what readers will learn.
-description: Learn about the basic details of deploying assets on SuperchainERC20 +description: Learn how to deploy and bridge tokens using the SuperchainERC20 standard across multiple chains
90-93: Enhance link descriptions in the next steps section.Make the links more descriptive to better indicate what readers will learn.
## Next steps -* Explore the [SuperchainERC20 specifications](https://specs.optimism.io/interop/token-bridging.html) for in-depth implementation details. -* Watch the [Superchain interop design video walkthrough](https://www.youtube.com/watch?v=FKc5RgjtGes) for a visual explanation of the concepts. -* Review the [Superchain Interop Explainer](explainer) for answers to common questions about interoperability. +* Learn about token bridging protocols in the [SuperchainERC20 technical specifications](https://specs.optimism.io/interop/token-bridging.html). +* Understand the architecture through our [30-minute video walkthrough of Superchain interop design](https://www.youtube.com/watch?v=FKc5RgjtGes). +* Get answers to frequently asked questions in the [Superchain Interop Explainer](explainer).pages/stack/interop/superchain-erc20.mdx (2)

1-24: Documentation style improvements neededPlease make the following adjustments to align with the documentation guidelines:
Header case:
- Change "How it works" to "How it works"
- Change "Major components" to "Major components"
- Change "Implementation details" to "Implementation details"
- Change "Next steps" to "Next steps"
Replace personal pronouns:
- "their tokens" could be replaced with "the tokens"
Technical term capitalization:
- Ensure consistent capitalization of "Superchain", "SuperchainERC20", and "Interop" throughout the document
Also applies to: 82-83
82-83: Improve sentence structure in the new link sectionThe current sentence could be more direct and clearer. Consider revising to:
-For step-by-step information on implementing SuperchainERC20, see [Deploy assets using SuperchainERC20](/stack/interop/deploy-superchain-erc20) +For step-by-step implementation instructions, see [Deploy assets using SuperchainERC20](/stack/interop/deploy-superchain-erc20).The revision:
- Makes the sentence more concise
- Adds missing period
- Removes redundant mention of "SuperchainERC20" since it's clear from context

5-6: LGTM! The metadata entry is well-structured.
The new entry follows the existing naming conventions and is logically placed after the related SuperchainERC20 documentation entry.
Let's verify the existence of the referenced documentation file:
✅ Verification successful
Documentation file exists and matches the metadata entry ✅
The deploy-superchain-erc20.mdx file is present in the expected location at pages/stack/interop/, confirming that the metadata entry correctly references an existing documentation file.

The title follows sentence case guidelines, and the callout effectively communicates the development status.
48-51: LGTM!
The next steps section provides clear guidance with appropriate resources.

This doc explains how to deploy assests using the
SuperchainERC20standard.The issue had minimal collateral, so there may be pieces missing; especially regarding code examples and how we want to message this as a company. I've left various comments where I think specific review is needed.
