【Notice】NFT Transfer Error on MetaMask Mobile

Thank you for playing GensoKishi Online.

We have confirmed an issue where NFT transfers from “My Inventory” on the GENSO Marketplace may fail when using the MetaMask mobile app (in-app browser).

■ Error Message

View: Root TypeError: Cannot read property 'toLowerCase' of undefined

■ Affected Environment

  • MetaMask Mobile App (smartphones only)
  • NFT transfers work normally on PC browsers using MetaMask

■ Cause

This issue is caused by a bug in MetaMask’s mobile NFT transfer functionality.
The same issue has already been reported on MetaMask’s official GitHub.

■ Temporary Workaround

Please use MetaMask on a PC browser to transfer NFTs until this issue is resolved.

■ Future Actions

As this issue originates from MetaMask’s mobile app,
a permanent fix will require an update from MetaMask.
We will provide further updates once the issue is resolved.

We sincerely apologize for the inconvenience and appreciate your understanding.
