Frequently Asked Questions.

If you have questions feel free to contact us

Q What is this service for?

ChainWatch monitors the Ethereum network in real time for abnormal transactions and evidence of fraud. Users subscribe to alerts on one or more smart contracts or crypto wallet so they know about unusual activity.

Q Why do I need it?

Whenever anomalous activity is detected in a smart contract that you’re subscribed to, you will receive a notification from ChainWatch so you can decide on the appropriate measures to take.

Q What exactly do you mean by "anomalous" activity?

We monitor key contract metrics to identify transactions that deviate from normal activity. This could be a high TX rate or large volume of outgoing Ether in a smart contract or unusually large transactions in a crypto wallet.

Q How can I receive notifications?

Simply specify the address of the contract or wallet you are interested in. We’ll send a link to confirm your details and then you’ll receive alerts via email or Telegram. You can subscribe to additional contracts/wallets in the same way.

Q Can I unsubscribe?

Yes, at any time. Each alert we send contains a link you can use to unsubscribe.
