Abstract

Smart contracts are computer programs that execute on the blockchain, receive and send transactions, and maintain a balance of cryptocurrency. In the recent past, we have witnessed a variety of attacks against smart contracts with cryptocurrency loses up to 50 million US Dollars. These attacks were possible due to errors in the smart contract logic. In this talk we investigate dynamic analysis approaches to secure smart contracts and discuss patching and hardening strategies.
