Just wrapped up a fun yet tricky part of my escrow project: fee implementation.
What I added:
Fee payout logic
Dynamic fee recipient address
Full test coverage with Foundry
A special Rejection contract to simulate fee transfer failures
This small feature really made me appreciate how complex simple things can be in Solidity when you care about:
⛽️ Gas efficiency
🔒 Security
✅ Test coverage
One cool challenge:
Making sure the contract reverts properly if the fee transfer fails without deleting the original amount. Sounds easy... wasn’t 😂
Now that everything passes (23/23 tests 💪), I'm moving toward multisig support next.
If you're also diving into Solidity, trust me — testing teaches more than coding.
Let me know what you think, or if you want to walk through your own fee logic!
