# Bundle Simulation

> Simulates multiple transactions sequentially.

> For the complete documentation index, see [llms.txt](/docs/llms.txt).

<Info>
  Try it out - [alchemy_simulateAssetChangesBundle](https://www.alchemy.com/docs/data/simulation-apis/transaction-simulation-endpoints/alchemy-simulate-asset-changes-bundle) and [alchemy_simulateExecutionBundle](https://www.alchemy.com/docs/data/simulation-apis/transaction-simulation-endpoints/alchemy-simulate-execution-bundle).
</Info>

With [Asset Changes](/docs/reference/alchemy-simulateassetchanges) and [Execution Simulation](/docs/reference/alchemy-simulateexecution), you are able to simulate 1 transaction and get asset changes, decoded logs, decoded traces and more.

What about simulating multiple transactions **sequentially**?

For 3 transactions (t1, t2, t3), think of being able to:

* use output of simulating t1 as input to simulating t2
* use output of simulating t2 as input to simulating t3
* etc.

The current bundle limit is 3 transactions. 4500 CU cost.
