# Priority Fee & Tip

### **Priority** Fee <a href="#priority-fee-and-tip" id="priority-fee-and-tip"></a>

Priority Fee is an additional transaction fee charged by Solana on top of Base Fee (the minimum cost of sending a transaction, 5,000 lamports for each signature included in the transaction). Due to limited computing resources, Leader nodes order transactions mainly by transaction value when producing blocks. Transactions with higher Priority Fee have a higher probability of being included in the next block. The CU Price of Priority Fee is provided by [`getTransactionfee`](/streams/network-fee-stream/solana/get-transactionfee.md) and is recommended to be set at least 1,000,000 when conscructing transactions.

### Tip <a href="#priority-fee-and-tip" id="priority-fee-and-tip"></a>

When constructing a transaction, you need to add a instruction of Tip transfer into the transaction(preferably added at the front position) to further speed up the inclusion. BlockRazor does not charge service fees from Tips. The Tip transfer amount is at least 100,000 Lamports (0.0001 Sol) . It is recommended to set it to the value returned by [`getTransactionfee`](/streams/network-fee-stream/solana/get-transactionfee.md). The account to receive Tip is:

To avoid the degradation of performance due to address occupation, causing transaction delay, please rotate the Tip account when sending transactions.

## 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://docs.blockrazor.io/transaction-submission/fast/solana/priority-fee-and-tip.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.
