Why I Never Use Copy-Pasted Contracts Without Understanding Them
So many repos out there full of “plug and play” Solidity code. Just paste and deploy they say. Yeah right.
Every time I’ve done that something went wrong. Either the logic wasn’t what I thought or it had some tiny bug hiding in a modifier.
One time I used a multisig contract from GitHub without reading line by line. Turns out it had a self-destruct option. Hidden in plain sight. Lucky it was just a test.
Now I read everything. Even if it’s boring. Especially if it’s boring.
Not saying don’t reuse code. Just don’t trust it blindly. Most copy-paste bugs aren’t from bad code. They’re from not knowing what the code does.
If you’re not 100% sure what every function does, you shouldn’t deploy it.
