Walkthrough

The changes update the application's upgrade process by modifying key upgrade handler invocations. In app/app.go, the New function now passes two additional keepers—MultiCoinRewardsKeeper and DistributionKeeper—to the upgrade handler. In app/upgrades/v2_0/upgrade.go, new imports for multi-coin rewards and distribution are added, the CreateUpgradeHandler function signature is updated to include these keepers, and a new function SetWithdrawAddressAndMultiCoinRewards is introduced. A conditional block triggers this new function when the chain ID is "kyve-1".

Poem

Hoppity-hop, I nibble in code's glade,
Upgrades emerging like a sunlit parade.
New keepers join the burrow dance,
Multi-rewards and distribution in a lively trance.
With each line I hop and cheer,
A rabbit’s delight as progress draws near!

  • @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.
