I’ve been learning Solidity by building an escrow smart contract for milestone-based payments between clients and artists.

But instead of stopping at the happy path — I wanted to understand failure cases too.

So I used Foundry to write a full test suite that covers:
✅ role-based access control
✅ milestone validation
✅ reverts for unauthorized actions
✅ edge cases like double validation or overpayments
✅ gas profiling for critical functions

All contracts are modular for clarity:

  • BaseContract.sol for storage
  • ValidationContract.sol for validator flow
  • EscrowContract.sol for deposits, refunds, and release
  • ArtVault.sol ties it all together

Full repo with README, tests and gas report here:

Feedback welcome — especially from other Solidity learners or people who audit/test smart contracts regularly.
