Tenderly Alerts alternative for contract monitoring
Tenderly is a full developer platform: debugger, simulations, virtual testnets, node RPC and alerts. Alerts are available only on the paid plan, and that plan, Tenderly Console, is priced through sales. If you only need alerts from your contracts on Ethereum, BNB Chain, Base or Arbitrum, SmartAlert does that part on its own. It is free in Telegram, and Pro costs $30/mo with the price on the site.

When to choose Tenderly
You already use Tenderly
for debugging and simulations. Its alerts sit next to your traces.
You need chains other than Ethereum, BNB Chain, Base and Arbitrum
You need alerts in Sentry,
or want an alert to trigger a Web3 Action.
When SmartAlert fits
- You need alerts, not a full platform, and want to start today without a sales call.
- Your contract's activity changes through the day. A fixed threshold is either noisy at peak hours or silent at night. SmartAlert compares each hour with the same hour on previous days.
- You want to see how often a rule would have fired before you turn it on.
FAQ
Can I use SmartAlert and Tenderly together?
Yes. Many teams keep Tenderly for debugging and use a separate tool for alerts. SmartAlert only reads public chain data.
Is there a free trial of Pro?
A new project gets Pro limits for 14 days, no card needed. After that, Free keeps Telegram alerts.
Does SmartAlert simulate transactions?
No. It watches what already happened on chain and sends alerts.

Try it on your own contract
An address is enough. The first 14 days get Pro limits, and rules are checked on history before they go live.
