Floating pragma allows compilation with unintended compiler versions
Description
Both NFTDealers.sol and MockUSDC.sol use a floating pragma ^0.8.34 which allows compilation with any Solidity version >=0.8.34 <0.9.0. Future compiler versions may introduce bugs or breaking changes that affect contract behaviour.
Risk
Likelihood: Low
Impact Contract may behave differently across compiler versions.
Deployed bytecode may not match what was audited or tested.
Recommended Mitigation Lock the pragma to a specific version:
- pragma solidity ^0.8.34;
+ pragma solidity 0.8.34;
