Let’s talk about flash loans.
In many attacks, attackers use flash loans to borrow huge sums and manipulate price oracles that look only at the spot price of a single pool.
To be honest, I only learned this later: using a flash loan requires writing a smart contract or using specialized tools, so be especially wary of bots claiming to offer one-click flash loan arbitrage.
The lending protocol Aave, associated with $AAVE , supports flash loans.
Only invest what you can afford, and leave yourself plenty of room.
