New video by our Conflux Devs Community Functions are the core engine of any smart contract -they are used to define behaviors, enforce logic rules, and expose actions to users and other protocols. This new tutorial walks through how Solidity functions work from the ground up, including declarations, return values, visibility, view vs. pure modifiers, memory vs. calldata, and practical rules for writing cleaner, safer code. https://www.youtube.com/watch?v=2PO2Y-4dDv8
