Attacks on Ethereum Smart Contracts

blog

I just made a video covering common attacks on Ethereum’s smart contracts. I used live0verflow’s techniques to record and edit this one so it’s going to feel different from the others :) It’s a tl;dr of A survey of attacks on Ethereum smart contracts by Nicola Atzei and Massimo Bartoletti and Tiziana Cimoli.

ps: many thanks to Matthew Di Ferrante for the help!
