Blockchain platforms and smart contracts are vulnerable to security breaches. Security breaches of smart contracts have led to huge financial losses in terms of cryptocurrencies and tokens. In this paper, we present a systematic survey of vulnerability analysis of smart contracts. We begin by providing a brief about the major types of attacks and vulnerabilities that are present in smart contracts. Then we discuss existing frameworks, methods and technologies used for vulnerability detection. We summarise our findings in a table which lists each framework and the attacks it protects against.
