The generated smart contracts provide support for multi-step transactions th...
CVE-2024-26149
Vyper is a pythonic Smart Contract Language for the ethereum virtual machine. If an excessively large value is specified as the starting index for an array in abidecode, it can cause the read position to overflow. This results in the decoding of values outside the intended array bounds, potential...
CVE-2022-36061
Elrond go is the go implementation for the Elrond Network protocol. In versions prior to 1.3.35, read only calls between contracts can generate smart contracts results. For example, if contract A calls in read only mode contract B and the called function will make changes upon the contract's B...
Adaptive Plan-Execute Framework for Smart Contract Security Auditing
