Supported Networks

CoinBuddy supports token deployment across multiple blockchain networks, offering both testnet (free testing) and mainnet (production) environments. Choose the network that best fits your project's needs and budget.

Start with Testnets

Always test your token creation on testnets first! It's completely free and allows you to experiment with features before deploying to mainnet.

Testnet Networks (Free Testing)

Perfect for learning, testing, and experimenting with token creation at no cost.
