Metamask Extension Bug Importing A Custom Token Does Not Work Symptom Users are unable to import custom tokens into their Metamask wallet, despite entering the correct token address and other required details. The import process seems to fail without providing any specific error messages, leaving users confused about the issue. Technical Root Cause The error occurs due to a bug in the Metamask extension, which prevents it from correctly processing the import request for custom tokens. This could be due to outdated extension versions, incorrect token details, or issues with the Ethereum network connectivity. Manual Overrides Try updating Metamask to the latest version to ensure you have the bug fixes. Manually add the token using the token's JSON ABI: json { "address": "0x...token address...", "abi": [...token abi...], "name": "...token name...", "decimals": ...token decimals... } Clear browser cache and cookies to ensure a fresh start. Prerequisites: Metamask extension installed Ethereum mainnet or testnet selected Correct token address and details available For advanced troubleshooting, consider using an external Ethereum console to verify token details and test connectivity.
