Metamask Can't Import Private Key: Troubleshooting Guide

1. Ensure Compatibility

Verify that the private key you are trying to import is compatible with Metamask. Metamask supports private keys for the following cryptocurrencies:

• Ethereum
• Binance Smart Chain (BSC)
• Polygon
• Avalanche
• Celo
• Fantom Opera

2. Check Private Key Format

Metamask currently supports importing private keys in the following formats:

• Uncompressed WIF: Starts with "5"
• Compressed WIF: Starts with "K" or "L"
• Hex: A 64-character hexadecimal string

3. Verify Private Key Correctness

Double-check that the private key is entered correctly and does not contain any leading or trailing spaces.

4. Confirm Network Selection

Ensure that Metamask is set to the correct network (e.g., Ethereum, BSC) corresponding to the private key you are importing.

5. Clear Cache and Cookies

Clearing your browser's cache and cookies can resolve certain issues related to private key import.

6. Update Metamask

Install the latest version of Metamask to ensure compatibility with the latest security updates and features.

7. Reset Metamask

As a last resort, consider resetting Metamask to its default settings. This will delete all existing accounts and transactions, so backup any important data beforehand.

Extended Troubleshooting

If the above steps do not resolve the issue, consider the following additional troubleshooting measures:

• Use a Different Browser: Try importing the private key using a different browser (e.g., Chrome, Firefox).
• Disable Browser Extensions: Deactivate any browser extensions that may interfere with Metamask or web3 functionality.
• Use Recovery Phrase: If you have the recovery phrase associated with the private key, use it to create a new wallet in Metamask instead of importing the private key directly.
• Contact Metamask Support: Reach out to Metamask's customer support team for further assistance and guidance.
