Contract Lifecycle

A contract does not jump straight from idea to production. Developers move through a lifecycle: write code, compile it, deploy it, and then call it under real network conditions where each execution can succeed or revert.

Compilation matters because humans write Solidity, but Ethereum runs low-level bytecode. Deployment is a special transaction that stores that bytecode on chain and initializes the contract's first state.

After deployment, every interaction tests your assumptions. Successful calls update storage and emit events. Reverted calls undo state changes, which is why debugging inputs, permissions, and edge cases is such a central habit in Web3.
