Garden Finance Shuts Down App After $450K Exploit — Here's What Happened and Why It Matters

WHY IT MATTERS

Think of Garden Finance like a currency exchange booth that lets you swap one type of crypto for another across different blockchains. To make these swaps trustless — meaning neither party has to trust the other — they use a mechanism called a hash time-locked contract (HTLC), which is essentially a digital lockbox that only opens when both sides fulfill their part of the deal within a time limit. An attacker found a flaw in this lockbox mechanism and was able to steal $450,000. This matters because similar lockbox technology is used across many crypto platforms, and exploits like this remind us that even clever security designs can have vulnerabilities. If you're new to crypto, this is a good example of why it's important to be cautious with newer DeFi protocols and never invest more than you can afford to lose.
