Hacks, exploits and scams have sadly became commonplace in Web3 and they usually don't target the big fish like Binance.
The vast majority target regular users, especially those new to blockchain. To help, we put together a 3-part guide on how to protect yourself 👇

Today seems like a good time to cover just a few of the potential security applications for Reactive contracts, so let's take a look! 🧵
Liquidation Protection
A Reactive Contract can subscribe to Aave health factor changes (or CRON ticks) and automatically:
- Deposit more collateral
- Repay debt
- Both
The moment your health factor drops below your threshold.
