# eth\_sendRawTransaction

Base RPC 是 BlockRazor 為 Base 提供的交易發送接口，用於將已簽名的原始交易發送到鏈上。目前僅支持 `eth_sendRawTransaction` 方法，並同時提供 gRPC 與 HTTPS 兩種接入方式。

### 為什麼選擇BlockRazor Base RPC

對於 Wallets 和 DEX 來說，交易發送能力不只是“能夠發出交易”，還關係到不同地區用戶的訪問質量、發送鏈路的穩定性，以及高峰時段下的整體體驗。直接連接 Base 官方 Sequencer 雖然能夠滿足基礎發送需求，但對於服務全球用戶、關注跨區域表現和生產環境穩定性的業務來說，發送路徑本身仍然存在進一步優化空間。BlockRazor Base RPC和官網原生交易發送服務的對比詳見 [Benchmark](https://blockrazor.io/zh/blog/20250922basebenchmark/)

**全球多點部署**

相比直接連接 Base 官方 Sequencer，BlockRazor Base RPC 在多個核心區域提供發送入口，適合 Wallet 和 DEX 根據自身服務部署位置選擇更接近的 endpoint。對於服務全球用戶的業務來說，更接近業務服務器和核心用戶區域的發送入口，通常有助於縮短請求路徑，提升交易發送效率。

**跨洲專線**

BlockRazor Base RPC 的優化重點不僅在入口節點部署，也在區域 relay 之間的數據傳輸鏈路。相比完全依賴普通公網路由的區域間轉發方式，跨洲專線能夠大幅降低 relay 間傳輸的路由波動、擁塞和鏈路抖動影響，提升交易請求在整體發送鏈路中的穩定性和一致性。

## 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/rpc/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.
