Tips

Chat

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>.
    • Generate unit testing code for this file.
    • 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 generate unit testing code for this file.
    • @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:
    • @coderabbitai generate interesting stats about this repository and render them as a table.
    • @coderabbitai show all the console.log statements in this repository.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

I'd recommend using something like strings.Join(append(AllCapabilities(),"dydx"), ","). That way you don't need to manually update the capabilities when you upgrade x/wasm.

You need this if you want contracts to get access to env.transaction. Otherwise they get None there.

It's probably less important for permissioned chains, but still good to have in case someone finds a way to cause an infinite loop in a contract call.

It would be great to use wasmvm v1.5.5 because it includes some security fixes.

Do you actually mean to skip this ante handler if there are multiple wasm exec in the same tx?
To my understanding you probably want to discard the tx, in that case you should just return an error

you should also add wasmd ante handlers :

  • CountTXDecorator is useful because it provides position data to the contract via Env . The motivation is to add a unique ID to the contract environment to distinguish between multiple executions within the same block but in different tx versus a reentrant call within the same msg or tx.
  • LimitSimulationGasDecorator limits the maximum gas available in simulations, preventing the "infinite gas" issues.
    So to avoid well known issues and keep the full compatibility both ante handlers should be provided.

I reviewed the Rust bits and they look fine save for nitpicks.

Is this contract meant as an example for contract devs to use as a reference? I worry accepting the DydxQuery type from the bindings lib would be confusing to them. It's more typical for a contract to define its own QueryMsg.
