A Comprehensive Guide on Public Testnets
Understand the role of public testnets, their advantages, limitations, and how BuildBear can enhance your DApp testing experience.
What are Testnets?
Testnets mimic Mainnets but operate with tokens having no real-world value, providing a safe environment for testing smart contracts and DApps.
Testnet vs Mainnet
- Mainnet: Real-world value transactions, operational risks, critical performance.
- Testnet: Risk-free, tokens without real-world value, ideal for development and debugging.
