Metamask Extension Bug Importing A Custom Token Does Not Work

Metamask Extension Bug Importing A Custom Token Does Not Work Symptom Users are unable to import custom tokens into their Metamask wallet extension, resulting in the token not being visible or accessible within the wallet. Technical Root Cause The error occurs due to a potential mismatch between the token's contract address and the network ID, or an issue with the token's metadata, such as its symbol or decimal places. Manual Overrides Verify the token's contract address and network ID to ensure they match the expected values. Check the token's metadata, such as its symbol and decimal places, to ensure they are correctly formatted. Use the following JSON configuration to manually add the token: json { "address": "0x...token contract address...", "symbol": "...token symbol...", "decimals": ...token decimal places..., "image": "...token image URL..." } Consider utilizing an external interface, such as MyEtherWallet, for troubleshooting token import issues. Prerequisites Metamask wallet extension installed and configured. Token contract address and metadata available. Basic understanding of Ethereum blockchain and token standards.
