Bug: The Hardhat Network runtime defaults to the "Osaka" hardfork due to a dependency update, while contracts are compiled for "Cancun", creating a testing environment mismatch.
_{Severity: HIGH | Confidence: High}

🔍 Detailed Analysis

The update to EDR 0.12.0-next.17 changes the default Hardhat Network hardfork to "Osaka". However, the project's hardhat.config.ts specifies evmVersion: "cancun" for compilation without explicitly setting the network's hardfork. This mismatch between the compilation target (Cancun) and the test execution environment (Osaka) can cause tests to fail. Potential issues include gas cost discrepancies, unexpected EVM behavior due to new EIPs in Osaka, transaction failures from different default gas limits, and broken error message assertions. The test suite is tightly coupled to the Hardhat Network's behavior, making it sensitive to such environmental changes.

💡 Suggested Fix

Explicitly set the hardfork in hardhat.config.ts to match the compiler target. Add hardfork: "cancun" to the hardhat network configuration object to ensure the test execution environment is consistent with the compilation settings.
