Poem

In the swamps of code, a new path is laid,
Kadena’s details, in YAML displayed.
With tokens and blocks, all neat as you please,
Six confirmations, block time a breeze.
So let the explorers roam,
For KDA’s found a home!

There are 3 ways to chat with CodeRabbit:

Review comments: Directly reply to a review comment made by CodeRabbit. Example:
- I pushed a fix in commit <commit_id>, please review it.
- Explain this complex logic.
- Open a follow-up GitHub issue for this discussion.
Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
- @coderabbitai explain this code block.
- @coderabbitai modularize this function.
PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:

22-22: Mind the incomplete RPC root, laddie

https://api.chainweb.com is the public host, but Chainweb expects a full path that includes the network (mainnet01) and chain number (0..19) for Pact calls. If the tooling blindly appends its own path you’re grand, but if it expects a ready-to-hit endpoint this will return a 404 quicker than a donkey on hot coals.

Double-check how Hyperlane composes Kadena requests and, if needed, change the entry to something like:
rpcUrls:
  - http: https://api.chainweb.com/chainweb/0.0/mainnet01/chain/0/pact
22-22: Nice fix on the scheme, smells less broken now

You’ve added the https:// that was missing in the last round. Tools won’t choke anymore. Good stuff.

will not be able to merge this PR until there is support for the kadena protocol type in the Hyperlane SDK

@paulbalaji

What we need to do to make Hypelane SDK to support kadena protocol?

is your intention to add metadata for kadena itself or the kadena evm?

For Kadena itself.
