Choosing a network
Toolblox can deploy the same workflow to many different blockchains. You pick the network in the Blockchain dropdown during deployment. Here's how to choose.
Start on a testnet
Whatever you're building, deploy to a testnet first. Testnets are free, so you can try the whole flow end to end without spending anything. Every supported network has a matching test network (for example Ethereum → Sepolia, Polygon → Amoy, Base → Base Sepolia).
Then pick a mainnet that fits
When you're ready for real users, choose a live network based on what matters to you:
- Low fees — networks like Polygon or Base keep transaction costs tiny.
- Maximum reach and trust — Ethereum is the most established.
- Stablecoin payments — if you want to charge in USDC, pick a network that supports it (see the supported blockchains table).
- No subscription needed — you can deploy to Redbelly without a paid plan.

The complete set of networks — with their test networks and stablecoin support — is in Supported blockchains. The Blockchain dropdown in the Deploy step always reflects what's currently available.
