How do you invoke a smart contract on Ethereum?

You just need to learn how to code in a smart contract language, and have enough ETH to deploy your contract. Deploying a smart contract is technically a transaction, so you need to pay gas in the same way you need to pay gas for a simple ETH transfer. However, gas costs for contract deployment are far higher.
