Push notifications so you can move faster
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
Alchemy webhook notifications guarantee "at-least-once" delivery, so you can rest easy knowing you won't miss an event.
""Alchemy Webhooks is a best-in-class feature that allowed us to deliver the best push notifications for Ethereum while minimizing upkeep and engineer hours. We estimate we save $240,000 each year with Alchemy Webhooks.""
