🐛 Smart Contract Exploits: What Can Go Wrong
Smart contracts are powerful because they're automatic and unstoppable. But that same power means bugs are permanent. A single vulnerability can drain millions in seconds — and there's no "undo" button on the blockchain.
Glitch is the wildcard Guardian who thinks like a hacker to find the bugs before the bad guys do. Understanding common exploits helps you evaluate which projects are safe.
💥 Common Smart Contract Exploits
1. Reentrancy attacks
A contract calls an external contract, which then calls back into the original before it finishes. This lets attackers withdraw funds multiple times. The famous DAO hack used this exploit.
2. Rug pulls
The team removes all liquidity or uses a hidden function to drain the contract. Signs: unverified contract, owner can withdraw, no liquidity lock, anonymous team with no track record.
3. Flash loan attacks
Attackers borrow millions in a single transaction, manipulate a price oracle, exploit the mispricing, and repay the loan — all in one block. Projects with weak oracle setups are vulnerable.
4. Hidden mint functions
Some contracts have hidden or obfuscated functions that let the owner mint unlimited tokens. This dilutes your holdings to zero. Always check if the contract has a mint function.
🔍 What Audits Actually Check
- ▸ Reentrancy vulnerabilities and state manipulation
- ▸ Owner privilege abuse (hidden functions, excessive control)
- ▸ Oracle manipulation and price feed reliability
- ▸ Token supply integrity (can new tokens be minted?)
- ▸ Fee mechanisms and fund flow transparency
💡 Key Takeaway
Audits reduce risk — they don't eliminate it. But an unaudited contract is like a car with no brakes. You might be fine, but do you really want to find out?
