Protect RPC

Protect RPC routes transactions through bloXroute’s private relay network, keeping them hidden from the public mempool until they are confirmed on-chain. This prevents frontrunning and sandwich attacks by MEV bots, improving execution quality for users.

Key Features

• Frontrunning protection – Transactions are not visible in the public mempool.

• No setup required – Works by simply replacing your RPC endpoint in supported wallets like MetaMask.

• Direct to block proposers – Transactions are sent privately to validators for inclusion.

How It Works

When you use Protect RPC, your transaction bypasses the public P2P network and is delivered directly to block proposers via bloXroute’s global Relay network. This ensures:

• No visibility to MEV bots before inclusion

• No sandwiching or frontrunning

• Higher likelihood of receiving the intended execution price

MetaMask Setup

You can use Protect RPC by adding it as a custom network in MetaMask. Here's how:

1. Open MetaMask in your browser.

2. Click the network dropdown at the top.

3. Select “Add network” or “Add network manually”.

4. In the form, fill in the fields using the details from the table below.

5. Click “Save”.

6. Switch to the new network — transactions will now route through bloXroute’s Protect RPC.

Solana – SOL Protect RPC

Endpoint: https://sol-protect.rpc.blxrbdn.com

SOL Protect RPC provides frontrunning protection for transactions on Solana Mainnet Beta. Transactions sent to this endpoint are routed to dynamically selected low-risk validators, reducing the likelihood of MEV-based attacks. This approach is similar to submitting transactions with the fastBestEffort parameter in the Solana Trader API.

⚠️ Currently, this endpoint supports only the sendTransaction method. It cannot be used as a full wallet RPC endpoint.
