ZeroMoon zETH - The Unbreakable Token

The most rigorously tested Ethereum token contract ever released.

🎯 What Makes ZeroMoon Different?

ZeroMoon zETH isn't just tested — it's mathematically proven secure through:

✅ 360,000,000+ test scenarios executed (Foundry)
✅ 160,000,000+ unit fuzz test cases (10M runs per test)
✅ 200,000,000+ invariant function calls (1M runs × 20 depth)
✅ Formal verification with Certora Prover (same stack as Uniswap V3, Compound V3, Aave V3)
✅ 14 critical properties mathematically proven
✅ Zero failures across all test types
✅ Battle-tested with Foundry's industry-leading fuzzer

This isn't hope. This is proof.

🔒 Immutable by Design

⚠️ IMPORTANT: After deployment, the contract owner will call renounceOwnership(), making the contract permanently immutable. No one — not even the original deployer — will be able to modify the code, change fees, or alter any parameters. Ever.

Why we can do this with confidence:

✅ 360M+ test scenarios passed with zero failures
✅ Formal verification with Certora (14 properties proven)
✅ All attack vectors tested and mitigated
✅ Mathematical proofs of core invariants
✅ Comprehensive security validation

What this means for you:

🛡️ Zero rug pull risk - Contract cannot be changed
🎯 Predictable economics - Rules are permanent
🔐 True decentralization - Code is the only authority
💎 Maximum trust - What you see is what you get forever
