Jrigada/min-example-1081

This repository was created to reproduce foundry-zksync issue #1081.

Problem: Running forge test --zksync crashes with an "unwrap panic" in the zkSync cheatcode runner, specifically failing to find a contract.

Expected Behavior: The test should revert or fail with an assertion, not crash the entire process.

Actual Behavior: The application panics with the error message: "failed finding contract for 0x6080604052..."

Error Location: crates/strategy/zksync/src/cheatcode/runner/mod.rs:573

Environment from Original Report:

• Forge Version: 1.0.0-foundry-zksync-v0.0.20
• OS: Ubuntu 24.04.1 LTS (WSL2)
• zkSolc: 1.5.15

1. Enable zkSync support in foundry.toml:

[profile.default.zksync]
enabled = true
codegen = "evmla"

2. Run forge test --zksync

⚠️ ISSUE NOT REPRODUCED

This repository has the correct zkSync configuration but the tests pass successfully instead of crashing with the reported panic. This suggests either:

• The issue has been fixed in recent versions
• Specific conditions are needed to trigger the panic that aren't present in this minimal setup
• Additional configuration or contract patterns are required
