‼️ IMPORTANT
Auto-reply has been disabled for this repository in the CodeRabbit settings. The CodeRabbit bot will not respond to your replies unless it is explicitly tagged.

• 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 gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @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.

17-17: LGTM! The correction to 256-bits is accurate.

The change improves technical accuracy as Secp256k1 public keys use a 256-bit field. When compressed, they are stored in 33 bytes total: 1 byte prefix for the y-coordinate parity and 32 bytes (256 bits) for the x-coordinate.

Consider adding a brief note about the compression format:

-Secp256k1 public keys can be compressed to 256-bits (or 33 bytes) per the format described [here](https://github.com/cosmos/cosmos-sdk/blob/v0.46.15/docs/basics/accounts.md#public-keys).
+Secp256k1 public keys can be compressed to 256-bits (or 33 bytes, consisting of a 1-byte prefix and 32-byte x-coordinate) per the format described [here](https://github.com/cosmos/cosmos-sdk/blob/v0.46.15/docs/basics/accounts.md#public-keys).

A compressed Secp256k1 public key is 256 bits for the x coordinate and 1 bit to determine if the y coordinate is even or odd. 256 + 1 = 257 which is 33 bytes.
