📝 WalkthroughWalkthroughThe pull request introduces additional documentation for key management in chain operators, specifically expanding the "Hot wallets" section of the key-management page. The new content focuses on the use of an open-source tool called "signer-proxy" that enables integration with AWS Key Management Service (KMS) and YubiHSM2 hardware security modules. The documentation provides technical details about how the signer-proxy tool connects to these key management systems and offers an endpoint compatible with the Sequence DiagramsequenceDiagram

29-32: Enhance the signer-proxy documentation section.While technically accurate, this section could be more helpful with the following improvements:
- Specify the primary purpose upfront (e.g., "To secure your privileged role keys...")
- Combine the two paragraphs to avoid repetition
- Add basic setup instructions or configuration guidance

Pattern **/*.mdx: "ALWAYS review Markdown content THOROUGHLY with the following criteria:
- Use proper nouns in place of personal pronouns like 'We' and 'Our' to maintain consistency in communal documentation.
- Avoid gender-specific language and use the imperative form.
- Monitor capitalization for emphasis. Avoid using all caps, italics, or bold for emphasis.
- Ensure proper nouns are capitalized in sentences.
- Apply the Oxford comma.
- Use proper title case for buttons, tab names, page names, and links. Sentence case should be used for body content and short phrases, even in links.
- Use correct spelling and grammar at all times (IMPORTANT).
- For H1, H2, and H3 headers:
- Use sentence case, capitalizing only the first word.
- Preserve the capitalization of proper nouns, technical terms, and acronyms as defined in the 'nouns.txt' file located in the root directory of the project.
- Do not automatically lowercase words that appear in the 'nouns.txt' file, regardless of their position in the header.
- Flag any headers that seem to inconsistently apply these rules for manual review.
- When reviewing capitalization, always refer to the 'nouns.txt' file for the correct capitalization of proper nouns and technical terms specific to the project.

Hi @bradleycamacho @sbvegan we would like to discuss on getting this pull request merged. Do you have any recommendation or should we move our Readme.md to this key management page? |
Description
We have developed signer-proxy, an open-source tool that connects AWS KMS or YubiHSM2 backend and exposes an endpoint compatible with the
eth_signTransactionRPC method.This enables OP Stack chain operators to easily use AWS KMS or YubiHSM2 to secure their key for privileged roles by just launching the signer-proxy server and configure OP Stack services according to use signer-proxy RPC server instead.
This pull request add recommendation to use signer-proxy in the Key Management page.
