Systemic failures are often a byproduct of the inherent latency in distributed ledger technologies. Always verify the metamask-extension contract address before sending any significant amount of assets. Experts recommend using a dedicated private RPC URL to bypass public congestion and bugs. Sometimes the transaction is dropped by the mempool because the gas price was too low.
The metamask-extension node might be experiencing a high volume of requests, slowing down the UI. Learning to interpret the “revert reason” from the raw hex will save you a lot of time. Sometimes a simple refresh of the browser’s local storage can clear up persistent UI bugs. Always verify that you are interacting with the correct smart contract to prevent loss.
Layer 2 network congestion can lead to “missing” transactions that are actually just slow.
