What are Testnets?
Testnets are blockchain networks that replicate the functionality of mainnets but use valueless tokens. Tools and services in this category include testnet deployments, faucet services for acquiring test tokens, testnet explorers, and simulation environments. These tools allow developers to deploy, test, and debug smart contracts and decentralized applications in a risk-free setting before launching on mainnet. Primary users are developers and product teams who need to validate code, experiment with new features, and ensure security without incurring real costs or risks. Key characteristics of testnet tools include network stability, compatibility with mainnet protocols, and easy access to test tokens. Related categories include infrastructure providers and monitoring tools, which often support testnet environments. Developers should seek testnet tools early in the development lifecycle to validate functionality and performance before mainnet deployment.
