Hi, I’d like to take this issue.

I have experience securing smart contracts against reentrancy. I can implement proper guards, ensure state updates happen before external calls, and add tests to cover potential attack scenarios.

ETA: ~2–3 hours.

Thanks!

Hi Maintainer! I'd like to be assigned to Issue #254 because I've secured similar tokenization modules by applying the Checks-Effects-Interactions pattern and adding reentrancy guards, and I can write thorough tests to verify the vulnerability is fully eliminated.
