-Flashbots Protect is a user-friendly, secure, and powerful way to transact on Ethereum for both novices and sophisticated users.
+Flashbots Protect is a secure way to protect Ethereum transactions from harmful front-running and sandwich attacks and to receive refunds on MEV generated from any back-running.
 
 It has the following key benefits:
 
-- **Configurable:** you can choose which builders to send to and your mev-share settings.
-- **Frontrunning protection:** your transaction will not be seen by bots hungry to frontrun you in the public mempool.
-- **Get backrunning MEV back**: if your transaction creates MEV in backrunning, you get up to 90% of it back through [MEV-Share](/flashbots-mev-share/introduction).
-- **No failed transactions:** your transaction will only be included if it doesn't include any reverts, so you don't pay for failed transactions.
+- **Configurable:** You can choose which builders to send to and your mev-share settings.
+- **Frontrunning protection:** Transactions are sent to a private Flashbots mempool where they will be hidden from front-running and sandwich bots.
+- **Receive backrunning MEV refunds**: If your transaction creates MEV via backrunning, you will receive up to 90% of it back through [MEV-Share](/flashbots-mev-share/introduction).
+- **Revert protection:** Users do not pay for failed transactions since transactions that would revert are excluded.
