ChatGPT says: If your Keystore is for Ethereum or EVM-compatible chains (e.g. BSC, Polygon, Avalanche, etc.)
These are the best options:
MetaMask 🦊
✅ Most common and easiest to import — simply choose “Import using JSON file” and upload your Keystore.
✅ Works with all EVM-compatible networks.
✅ Browser + mobile app support.
⚠️ Be sure you know the password for your Keystore — MetaMask can’t recover it.
I am going to have to do this sometime this weekend!
