Summary
This Pull Request fixes Issue #10.
The Problem
Currently, running
forge testfails with anmcopy instruction error.Root Cause
This error occurs because the project's Solidity compiler (
v0.8.24) is modern enough to generate themcopyopcode, which was introduced in the Ethereum Cancun upgrade. However, the Foundry test environment's EVM version was not explicitly set, defaulting to an older version that does not recognize this new opcode.The Solution
This PR resolves the issue by explicitly setting
evm_version = "cancun"in thefoundry.tomlconfiguration file.Impact
This change unblocks all contributors who wish to run the smart contract test suite locally, improving the overall developer experience and enabling further testing.
