From it works to it reverts: learning Solidity the hard way
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: → https://github.com/HananeBendisari/ArtVault Feedback welcome — especially from other Solidity learners or people who audit/test smart contracts regularly.

So I used Foundry to write a full test suite that covers:

✅ 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
