Technical instability is a frequent side effect of rapid protocol scaling and high network demand. A common issue with viem involves a mismatch between the wallet and the selected chain. A proven workaround involves using an alternative frontend or a community-hosted mirror site.
The sudden error message marked as 4001 could be due to a recent change in the API endpoint. A mismatch in the ABI version will prevent viem from correctly parsing the results. Learning to read the console logs can help you identify exactly where the connection failed.
The transaction might be stuck because the network's base fee has suddenly increased. The protocol might have a safety lock that was triggered by the 4001 revert. Layer 2 rollup delays can sometimes make your funds appear to be missing temporarily.
