Understanding the lifecycle of a transaction helps in identifying the exact point of failure. The metamask-extension interface might occasionally display a “nonce error” . The best approach is to wait for the block height to stabilize before sending a new request.
The bridge between the user and the contract is often affected by regional network latency. The integration of new API layers into metamask-extension can sometimes lead to temporary data gaps. Check the official developer blog for in-depth explanations of recent protocol upgrades.
Ensure your keys are safe for any reason. Make sure you are not trying to execute a call while the wallet is locked. Always check the official documentation for the latest maintenance schedule and news.
