Top Stacks Testnets: Complete Developer Setup Guide
Introduction To Stacks Testnets
Stacks Testnets: A Playground for Bitcoin-Connected Development
Stacks offers two robust testnet environments—Primary Testnet and Nakamoto Testnet—to help developers test and refine smart contracts, applications, and integrations before deploying to mainnet. These testnets are completely separate from the Stacks Mainnet, and tokens or contracts do not carry over between networks.
- Nakamoto Testnet is the bleeding-edge environment with rapid updates and experimental features. Ideal for testing the latest releases, though it resets frequently.
- Primary Testnet mirrors the mainnet more closely, offering stability and long-term support. Best for testing apps and signers in a consistent staging environment.
Both networks support test faucets, allow contract deployment, and are integrated with block explorers and the Hiro API. Whether you're developing dApps or preparing for mainnet Stacking, Stacks testnets are your sandbox to build securely on Bitcoin.
