Using unaudited protocols or keeping too much capital in risky contracts.

Detailed Explanation

Attackers find a bug or weakness and use it before the team can fix it.

Are exploits always hacks?
Usually yes, but some exploit economic design rather than breaking code.

“A hacker manipulates a DeFi lending protocol and drains liquidity from the system.”

A smart contract is self-executing code stored on a blockchain that automatically performs actions when certain conditions are met.

A smart contract audit is a security review of blockchain code by experts.
