The Ethereum Alarm Clock from ChronoLogic is live!

Starting now, you can schedule Ethereum transactions on the mainnet.

Why would you want to schedule a transaction? Well, there are many reasons:

  • Maybe you want to get into that latest hot ICO but you’ll be away from your computer
  • Maybe you want an ENS domain name and don’t want to miss the reveal period
  • Maybe you need to pay at a certain time for a subscription
  • Maybe you want to send yourself a reminder in the future (though there are probably better options for this)
  • and much more!

Optionally: see how your transaction is executed for you without need to interact with it anymore.

How do I use it?

Go to, click “Send Ether & Tokens”, toggle the “Send Later” switch. Then you can provide all the details required for scheduling a transaction.

We have a dedicated help article which will tell you everything about this functionality. Continue reading: How To Schedule Transactions On

Can I cancel and get my funds back?

  1. Go to ChronoLogic Dapp and find your transaction. You can use the search box for that.
  2. Click your transaction and open the “details” view.
  3. Select transaction owner Ethereum account in MetaMask.

Now you should be able to click the “Cancel” button and get your funds back.

Click the button, you will see MetaMask send a transaction confirmation pop-up. It will send “cancel” transaction and you’ll retrieve your funds as soon as the transaction is processed by the network.

Earn ETH by executing transactions

As a part of decentralization, anyone with some Ether can act as a transaction executor agent — also known as a TimeNode. TimeNodes get rewarded an ETH bounty for executing transactions. It’s up for grabs. You just need to be first to claim and execute the transaction while running the TimeNode. It’s an automated process, which doesn’t require a lot of configuration.

To start acting as a TimeNode there are two basic steps:

Is it secure?

Scheduling and execution is secured by using smart-contracts. 🔒 The code of those smart-contracts is secured by automated test suites — they confirm the correctness of mathematical calculations as well as assure that the scheduled transaction life-cycle works properly. Additionally, the code for the Ethereum Alarm Clock has passed an audit.
