# Gas Protect RPC

**Gas Protect RPC** offers advanced protection for Ethereum transactions by combining frontrunning prevention with gas efficiency. It converts each transaction into a **Flashbots single-transaction bundle**, ensuring that the transaction stays private and won’t consume gas if it would revert.

#### **Key Features**

* **Frontrunning protection** – Transactions are not broadcast to the public mempool.
* **Gas protection** – Reverting transactions are not included, avoiding wasted gas fees.
* **Flashbots integration** – Transactions are bundled and sent to block proposers privately.

#### **How It Works**

When a transaction is sent to the Gas Protect RPC:

1. It’s immediately wrapped into a one-transaction Flashbots bundle.
2. It’s **simulated** off-chain — if it’s likely to revert, it is not sent.
3. If valid, it is sent privately to Ethereum block proposers for inclusion.
4. It remains hidden from the public mempool until mined.

This protects against:

* **Wasting gas** on failed or reverted transactions.
* **Frontrunning and sandwich attacks** by MEV bots.
