# Prepare SOL

Prepare SOL for Solana network fees and account rent, obtain it through a supported service, confirm the correct network and check the wallet balance.

### What is SOL?

SOL is the native cryptocurrency of the Solana blockchain, required for paying transaction fees and other use cases (such as staking to secure the network).

### **Transaction Fees on Solana:**

* Transaction fees on the Solana blockchain are paid using SOL. This means that as a user, whenever you want to initiate any type of on-chain operation, your wallet must have SOL.
* When you initiate a transaction on SlerfTools, you need SOL to pay for the transaction fees.

**Note:** 0.000000001 SOL = 1 lamport (one billionth of a SOL).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.slerf.tools/en/solana-guide/prepare-sol.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
