What is Alchemy Smart WebSockets?

Alchemy Smart WebSockets provides persistent blockchain subscriptions for applications that need live onchain updates. Developers can subscribe to real-time events such as new blocks, pending transactions, logs, and other supported chain activity without repeatedly polling RPC endpoints. Smart WebSockets is used by wallets, trading apps, NFT products, analytics systems, and backend services that need low-latency data from Alchemy's node infrastructure.
