# eth\_sendRawTransaction

### Introduction

`eth_sendRawTransaction` is a Fast mode transaction sending interface provided by BlockRazor for Base, used to send signed transactions with lower latency. It currently supports standard JSON-RPC style requests, allowing users to quickly integrate it with their existing sending logic.

The capabilities of `eth_sendRawTransaction` differ between RPC and Fast modes:

* In RPC mode, `eth_sendRawTransaction` is more suitable as a standard sending entry point, emphasizing global multi-point deployment and intercontinental leased lines.
* Fast is better suited for scenarios where the priority is to send single transactions quickly and enter execution path faster.

{% hint style="info" %}
Fast Mode is not tied to the subscription plan, but each transaction sent in Fast Mode must include a tip sent to the address `0x9D70AC39166ca154307a93fa6b595CF7962fe8e5`. The minimum tip amount is the greater of 0.000003 ETH or MaxPriorityFee \* 5%.
{% endhint %}

## 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/base/eth_sendrawtransaction.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.
