# eth\_sendRawTransaction

### 介紹

Fast模式基於BlockRazor的全球高性能網絡實現交易最低延遲上鏈，適合對交易上鏈速度存在極致要求的用戶。相比[Send RawTx](/tc/transaction-submission/fast/bsc/fast-tx.md) ，Fast模式的交易不會通過mempool廣播，在確保速度的同時具備隱私性。Fast模式的交易發送方法和`eth_sendRawTransaction`兼容。

{% hint style="info" %}
Fast模式不和訂閱計劃綁定，但每筆交易中需要包含轉賬至0x9D70AC39166ca154307a93fa6b595CF7962fe8e5的tip，金額至少為0.000025 BNB 或 Transaction Fee 的5%
{% endhint %}
