Definition ∞ A sending addresses spike indicates a sudden and notable increase in the number of unique blockchain addresses initiating transactions on a given network. This metric suggests a heightened level of activity from market participants who are moving assets, potentially for trading, staking, or transferring to self-custody. While not always indicative of bullish sentiment, a sustained spike can signal increased network utility or a significant event driving user engagement. It reflects a surge in transactional origination.
Context ∞ The discussion surrounding a sending addresses spike often involves analyzing the underlying reasons for the sudden increase, such as a major market event, a protocol upgrade, or a significant airdrop. A key debate centers on whether the activity represents organic growth or coordinated movements by large holders. A critical future development to watch for is how these spikes correlate with subsequent price action and network congestion, providing insights into market behavior and infrastructure demands.
