Mempool & Simulating Pending Transactions

Exploring Mempool and Filtering Pending Transactions

When exploring the transaction list in the Transactions tab (on the left), you can filter the default view and see Pending Transactions from the mempool as well - either by clicking the checkbox at the top or by clicking on Filter Transactions button in the top right.
When you click on and open a pending transaction, the expected outcome will be automatically simulated using the most recent state.

Simulating Pending Transactions

When you search for a transaction which is not yet mined and cannot be found in the system, Tenderly will retrieve said transaction directly from the node pending pool and Simulate it using the most recent state.
Simulated Pending Transaction - Failed
Simulated Pending Transaction - Successful
This means that you can see the expected outcome of your or any other transaction even before it is approved on the Mainnet.
This feature is available to all users, even if they are not logged in. That means that you can simulate pending transactions in this way even from our Explorer page without having an account - but you really should make one (it's free) so you can use the full power of our Simulations and Forks 🚀
