Metadata Update or Reset
If you encountered the error "Bad Input data. Failed to decode extensions. Please try updating the Metadata for Kusama/Polkadot network" while interacting with the Polkadot Network, it may be due to a runtime upgrade in Polkadot{.js} UI.
This tutorial will show you how to resolve the metadata on Keystone, a hardware wallet integration with Polkadot{.js} and SubWallet.
Update Metadata on Keystone
If you need to update the metadata for the Polkadot network using Keystone, follow these simple steps:
Click on the provided link to access the Metadata Portal for Keystone. Switch [Chain Specs] to [Metadata] to access a dynamic QR code.
Tap the [-] icon to activate the camera with your Keystone device.
Scan the QR code on the Metadata Portal and tap [Approve].
Note:
If you need to update the metadata for the Kusama network, click on [Kusama] on the Metadata Portal and follow the same steps.
Reset Metadata
If you need to reset the metadata for either Polkadot or Kusama network, follow these steps:
Ensure you have added the [DOT] or [KSM] by tapping the three dots on the right to access [Manage Assets], and then tapping [DOT] or [KSM].
Tap the three dots in the right corner.
Tap [Reset Data], read the warning, and tap [Confirm].
