Chapter · Master Base
The real risks
Base is useful, but no network is risk free, and it helps to know where the weak points are. Three stand out. First, bridge risk: bridges hold large amounts of funds and have been targets for hacks across the industry. Second, sequencer trust: one operator orders transactions today, so you rely on it behaving well. Third, smart contract risk: the apps you use are code, and buggy or malicious code can lose funds. Knowing these does not mean avoiding Base. It means using it with clear eyes.

What this lesson covers
Not financial advice
This chapter teaches how Base works, not what to buy or how to invest. Crypto can be volatile and mistakes are often permanent, since there is usually no undo button and no support line to reverse a bad transfer. The best protection is understanding: know what a bridge is before you use one, know that a single sequencer is a trust point, and slow down before approving anything. Curiosity plus caution is a strong combination. 🐜
What you get asked
Match each risk to what it is about.
The three main risks are bridges holding funds, trusting the single sequencer, and bugs in the app code you interact with.
Why are bridges a common target for hackers?
Bridges lock big pools of assets to back the coins on the other side. That concentration of value makes them a tempting target.
Because the apps on Base are made of code, ___ risk means a bug or bad contract could lose your funds.
Smart contract risk is the danger that app code has bugs or is malicious. Using audited, well known apps helps lower it.
What is a sensible way to manage these risks?
Stick to well known apps, test with small amounts, and only risk funds you can afford to lose. Never share your recovery phrase.
