# Priority Fee & Tip

### **Priority** Fee

Priority Fee是Solana在Base Fee（發送交易的最低成本，交易中每包含一個簽名花費5000 Lamports）基礎上的額外交易費用。由於計算資源有限，Leader節點在出塊時主要按交易價值對交易進行排序，Priority Fee越高的交易被優先納入下個區塊的概率越高。建議在發送交易時將CU Price至少設置為1,000,000。

### Tip

在構建交易時，需在交易中添加Tip轉賬指令（建議將Tip指令放在靠前位置），用於進一步加速交易上鍊。BlockRazor不從Tip中收取服務費。Tip指令轉賬金額至少為100,000 Lamports（0.0001 Sol），建議將Tip置為[`getTransactionfee`](/tc/streams/network-fee-stream/solana/get-transactionfee.md)返回的推薦值，接收Tip的账户地址為：

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 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/tc/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.
