SmartAlert
Contract alerts with thresholds tested on last month
Paste a smart contract address. SmartAlert collects its history, builds an hourly baseline and suggests alert rules — each showing how often it would have fired last month. Ethereum, BNB Chain, Base, Arbitrum. Alerts in Telegram, Slack, Discord, PagerDuty.
Hi Product Hunt 👋
Most contract monitors ask you for a threshold up front. You guess a number, and you learn it was wrong at 3 a.m. — either it stayed silent during an incident or it woke you up for nothing.
SmartAlert starts from the other end. You paste an address, and it reads the contract's past month on-chain. Events become metrics, each with a baseline for every hour of the day, because a contract at night is not the same contract at noon. Then it suggests rules, and next to every threshold you see how many times it would have fired on that history. You pick the trade-off; nothing runs until you turn it on.
What you can watch today:
• event spikes against the hourly baseline
• ownership changes and proxy upgrades
• transfers above an amount in USD
• a treasury or hot wallet balance below a floor
• contract state: call a view function every minute and alert on the answer
Networks: Ethereum, BNB Chain, Base, Arbitrum. Polygon and Optimism are next.
We test this against real incidents and write it up: in the Ronin bridge exploit, the vote threshold sat at 0 for 48 minutes before the first withdrawal, and no event said so. A contract-state rule would have fired 45 minutes early. The breakdown is on our blog.
Free plan: 2 contracts, 3 rules, Telegram. Your first project gets Pro limits for 14 days.
I'd love to hear what you monitor today and what it misses.
