Frequently Asked Questions

Q1: What is a smart contract reentrancy exploit?

An exploit where an external contract calls back into the calling contract before the state is updated, leading to unauthorized withdrawals.

Q2: How do I reduce contract deployment gas?

Use optimization compilers, minimize storage updates, pack variables, and use internal functions where possible.

Q3: What is the purpose of ABI in Web3?

The Application Binary Interface (ABI) defines how external clients interact with the compiled smart contract bytecode on the blockchain.
