    The goal is to

Continuously monitor the impermanent loss incurred for a position in Uniswap V3
And if there is a loss, we need to exit the position
It has to be 100% automated (the end user should not be expected to be online signing the transaction when the liquidity is pulled out)

Monitoring a position

We can use the Uniswap V3's subgraph to know a position's details like tokens, price at the time of providing liquidity, etc. We will also know the current tick in the pool.

    Sending Ether Cheat Sheet

TLDR

🥇 Instead of sending Ether, use the withdrawal pattern
🥈 If you really need to send Ether, use a safe wrapper like OpenZeppelin's Address.sendValue(addr, amount)
🥉 If you really need to send Ether without dependencies, use (bool success, ) = addr.call{value: amount}("")
