Capabilities to support your Web3 real-time interactions

Leverage Real-Time Data

Real-Time Notifications

Many Web3 products need to alert the user(s) in real-time when someone sends them a Web3 transaction, when a Web3 transaction is finished, and when the user’s wallet is updated. Since Web3 is, by design, an asynchronous set of technologies, it doesn’t have any built-in mechanism for alerting users when something has occurred. PubNub covers these real-time requirements.


Many Web3 products want a collaboration/chat layer for user-to-user communication related to Web3 use cases.

Game Player Sync

Many Web3 products are simply games that leverage Web3 concepts, and like any other game, PubNub can be useful for synchronizing game player turn-by-turn movements, leaderboards, and other game dynamics in a scalable, compliant way.
