FAQPage Schema
How do I test smart contracts using Hardhat and Foundry?▼

You test smart contracts using Hardhat and Foundry by writing unit tests, integration tests, gas optimization tests, and fuzzing scripts to validate Solidity contracts and verify DeFi protocol transaction flows.

What is mainnet forking in blockchain testing and when do I need it?▼

Mainnet forking is a testing mechanism that utilizes Hardhat to simulate live blockchain states. You need it when testing smart contracts against real blockchain conditions to ensure accurate environment simulation and transaction validation.

Can I use this framework to test DeFi protocols for potential vulnerabilities?▼

Yes, you can test DeFi protocols for vulnerabilities. The framework facilitates writing robust tests covering expected transaction flows, edge cases, and fuzzing to identify potential vulnerabilities before deployment.

What's the best way to write fuzzing tests for Solidity contracts?▼

The best way to write fuzzing tests for Solidity contracts is using a framework supporting fuzzing alongside unit and integration tests. This approach helps cover edge cases and potential vulnerabilities in smart contract logic.

Does this testing framework support gas optimization checks for smart contracts?▼

Yes, the framework supports gas optimization checks for smart contracts. It provides comprehensive testing capabilities that include gas optimization tests alongside unit tests, integration tests, and fuzzing for Solidity contracts.
