The onCloseIbcChannel function has been commented out to reduce the contract size, which is a critical step towards ensuring the contract's deployability. However, this change impacts the contract's ability to handle channel closure events. It's important to consider the implications of this removal on the overall system functionality and whether alternative optimizations could achieve size reduction without sacrificing important features.
Consider optimizing contract size through other methods such as code refactoring, using libraries, or splitting the contract into smaller contracts to preserve important functionalities like channel closure handling.

The contract uses SPDX license identifier UNLICENSED, which is appropriate for private or unpublished code but might not be suitable if the code is intended to be open-sourced. Ensure that the licensing aligns with the project's distribution and usage intentions.
Consider specifying a more specific license if the code is intended for open-source distribution, to clearly communicate usage rights and restrictions.

The contract specifies Solidity version ^0.8.9. It's good practice to use a fixed Solidity version or a more constrained version range to avoid unexpected behavior due to compiler updates.
Consider using a fixed version or a narrower version range for Solidity to ensure consistent contract behavior.
