This document provides examples of different types of smart contracts that can be created and run on the Ethereum blockchain. It shows sample code for contracts that manage a nation registry, issue crypto tokens, conduct crowdfunding, lock coins, run auctions, and create a multi-signature wallet. Each contract listing includes the contract address, brief description of its functionality, and link to the live contract on the Ethereum network.
