Transaction Stalling

Transaction stalling happens when a transaction remains in the mempool indefinitely because its fee is too low to be competitive. This effectively locks the user's funds, preventing them from being moved or used in other transactions.

Stalling is a major usability issue and a source of risk for traders who need to execute time-sensitive orders. It requires manual intervention, such as using Replace By Fee or cancelling the transaction, which adds complexity and cost.

Understanding the causes of stalling is vital for developers building financial applications that rely on consistent settlement. It represents a friction point in the market microstructure that can lead to missed opportunities and financial loss.
