# Ejercicio

Es hora de interactuar con un contrato que hayas desplegado en las clases del Módulo 2. Elige un contrato y una función a ejecutar dentro de ese contrato.

Necesitarás lo siguiente:

* Una URL de acceso a Sepolia.
* La clave privada de la wallet.
* La dirección del contrato.
* El ABI del contrato desplegado.
* El nombre de la función y los parámetros que requiere para su ejecución.

 💡 **TIP:** Necesitarás incluir los siguientes métodos en tu script

```jsx
const contract = new ethers.Contract(contractAddress, abi, provider);
const txResponse = await contract.someWriteFunction(params, { gasLimit, gasPrice });
```

Recuerda utilizar el archivo `.env` para guardar las variables de entorno y para proteger la privacidad de tu clave privada.

Incluye sentencias `console.log` para asegurar que el script se ejecutó correctamente y para mostrar el resultado de la función ejecutada.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://edp.ethkipu.org/modulo-4/toolkit-para-desarrollo-ethereum/toolkit/ethers.js/ejercicio.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
