Testnet

A blockchain that isn't fully operational and deployed to a production environment. Testnets are great for troubleshooting bugs, testing all features of the blockchain, and confirming that the system is secure before launching to mainnet. Testnets aren't monetized, so no funds are at risk and no fees are paid

Example

“A developer deployed their smart contract on the Ethereum Goerli testnet first to verify functionality before spending real ETH on a mainnet deployment.”
