Security

Increased security with static IP addresses and one authentication token per webhook - so if one webhook is compromised, others will not be.

Savings

See how we saved more than $3M annually moving workloads from excessive RPC calls to Alchemy Notify's push based notifications.

Reliability

Access to the most reliable and performant nodes

"We use Alchemy’s Smart Websockets to be immediately notified when new blocks are added to Ethereum, Polygon, Arbitrum, and Optimism. This method has driven a 3x latency improvement in our ingestion process, and as Alchemy optimizes the API, we continue to see improvements to performance."
