# State of Symbolic Execution for Ethereum Smart ContractsThe blog post introduces the concept ofsymbolic execution as a formal verification technique for smart contracts, which assigns symbolic values to input variables to explore multiple execution paths at the same time and check whether certain .. read more  

Smart contract developers can optimize their gas usage by limiting storage use, using events instead of storage, packing variables, using constants and immutable variables, and minimizing direct access to storage variables. Single-line swaps, loops, and unnecessary computation should be eliminated,.. read more  

A comprehensive survey of smart contract security highlightsreentrancy attack as one of the most common and famous types of attacks. While OpenZeppelin's ReentrancyGuard can mitigate this attack, it has fundamental limitations that make it difficult to prevent all reentrant calls. Spherex suggests.. read more
