You've initiated a standard withdrawal of 5 ETH from Arbitrum to Ethereum mainnet. Now begins the 7-day challenge period. Let's experience what this waiting period feels like and understand what happens each day.

📅 What Happens Each Day?
- Day 0:Withdrawal tx submitted to L1, batch posted
- Days 1-6:Validators monitor for fraud, can challenge if needed
- Day 7:Challenge period expires, withdrawal finalizable
- After 7d:Call finalize() on L1 to receive your funds
⚠️ Common Misconceptions
- ✗Myth: "My funds are frozen or at risk"
- ✓Truth: Funds are safe, just time-locked
- ✗Myth: "The network is slow"
- ✓Truth: Security mechanism, not performance issue
🧠 Why Exactly 7 Days?
Economic Security: Long enough that attacking becomes economically irrational. Validators can detect fraud, submit proofs, and execute slashing before the window closes.
Validator Response Time: Distributed validators worldwide need time to download batches, re-execute transactions, and verify correctness. 7 days provides comfortable margin.
L1 Congestion Buffer: If Ethereum is congested, validators still have time to get their fraud proofs included on-chain before the deadline.
💡 Some rollups are exploring shorter periods (1-3 days) with improved monitoring tools and faster proof generation.
💡 Key Insight
The 7-day delay isn't arbitrary—it's carefully calculated to give validators enough time to detect fraud while balancing user convenience. Think of it like a "cooling-off period" where the community can verify everything is legitimate before releasing funds. This trade-off (time vs trust) is fundamental to optimistic rollup design.
