Quasar RAT Disguised as an npm Package for Detecting Vulnerabilities in Ethereum Smart Contracts
Socket researchers uncover a malicious npm package posing as a tool for detecting vulnerabilities in Etherium smart contracts.
eth-create2-calculator
Advanced tools
This library calculates the create2 address of any given deploy code and from address. It works similar to [ethers.utils.getCreate2Address], but allows to pass in the full byte code and constructor arguments seperately.
This library calculates the create2 address of any given deploy code and from address. It works similar to [ethers.utils.getCreate2Address], but allows to pass in the full byte code and constructor arguments seperately.
