[milapsheth]

Note

Upgrades Hedera InterchainTokenService to v2.1.1 on mainnet and testnet, rotating component addresses and updating InterchainTokenFactory implementations.

• Hedera (mainnet/testnet):
  • InterchainTokenService (ITS):
    • Bump salt to ITS v2.1.1 and rotate tokenManagerDeployer, interchainTokenDeployer, tokenManager, tokenHandler, and implementation addresses.
  • InterchainTokenFactory:
    • Update implementation address for interchain-token-factory on both networks.

Greptile Overview

Summary

This PR upgrades Hedera's Interchain Token Service (ITS) to v2.1.1 on both mainnet and testnet environments.

Key Changes:

• Updated salt from "ITS v2.1.0" to "ITS v2.1.1" for both mainnet and testnet
• Updated contract addresses for:
  • tokenManagerDeployer
  • interchainTokenDeployer
  • tokenManager
  • tokenHandler
  • implementation
  • InterchainTokenFactory implementation
• Maintained consistent proxySalt at "ITS v1.0.0" (as per custom instructions)
• address and predeployCodehash fields remain unchanged, as expected for a proxy upgrade

Issues Found:

• The version field in both files remains at "2.1.0" but should be updated to "2.1.1" to match the salt and deployment version. This was correctly done in the stagenet upgrade (commit 59c3e26).

Confidence Score: 3/5

• This PR is generally safe but requires a version field correction before merging
• The changes follow the established upgrade pattern and correctly update contract addresses. However, the version field was not updated from "2.1.0" to "2.1.1" in both config files, creating an inconsistency with the salt field and the actual deployment version. This is a metadata issue that should be corrected for accuracy, though it won't affect the deployed contracts themselves.
• Both axelar-chains-config/info/mainnet.json and axelar-chains-config/info/testnet.json need the version field updated to "2.1.1"
