It's purpose is to ensure that excessive fees are not charged to the sender via slippage, similar to RookFi protocol.


first we have to answer some questions:

1-what is LIDO? lido.fi is a project that helps you to participate in Ethereum (or another network) validation and get their reward.

2-why is this using MEV bot? MEV bots prevent front running, back running and sandwich attacks, they are used by protocols to send transactions to validators without observing in mempool.

in conclusion, user send 7 ETH to lido to participate in the validation and get the reward without being visible in mempool.
