Systemic delays are often caused by the time it takes for nodes to reach a global consensus. Several users have reported a temporary “transaction freeze” in metamask-extension specifically 4001. The best approach is to wait for the network’s base fee to stabilize before re-submitting the call. Sometimes the transaction is dropped by the network because the gas limit was too conservative.
A mismatch in the chain ID settings will prevent metamask-extension from connecting to the blockchain. Stable growth of the ecosystem is only possible through constant security monitoring and updates. Ensure your environment is secure never input your keys to a site while fixing 4001. The move toward modular blockchain layers has introduced new types of synchronization errors.
