# Execute transactions | Plasma

> Plasma transaction execution JSON-RPC methods — simulate eth_call executions and estimate gas costs without broadcasting transactions to the Plasma blockchain.

Executing and simulating transactions on the Plasma blockchain can be done using the following methods:

</CardGroup>

This information can be used for:

* **Gas estimation** — calculate required gas before sending transactions
* **Transaction simulation** — test transaction execution without state changes
* **Smart contract testing** — verify contract behavior before deployment
* **DApp optimization** — optimize transaction parameters for cost efficiency
