Deploy your smart contract

Deploying is the moment your workflow becomes a real smart contract, live on a blockchain. Toolblox assembles the contract from pre-audited building blocks and your wallet publishes it — one click, no code.

Testnet or mainnet?​

There are two flavors of deployment:

  • Testnet — a free practice network. Deploy here as often as you like while you build.
  • Mainnet — the real, public network. Your contract is live and permanent, and it costs real gas.
tip

Always deploy to a testnet first and try the whole flow end to end. When it behaves exactly as you want, deploy the same workflow to a mainnet.

Deploying, step by step​

  1. Finish building and pass the Test step.
  2. Open Deploy (testnet) or Publish (mainnet).
  3. Choose a Blockchain from the dropdown (for example Ethereum Sepolia for a testnet, or Base Mainnet for a mainnet).
  4. Connect your wallet. If something's missing, a red note tells you what to fix (for example "Wallet not set up").
  5. If your workflow handles money, pick a Currency — the network's own coin, a stablecoin such as USDC, or a token you created. See Token payments.
  6. Choose any Standards you need (such as making items tradable NFTs). When unsure, leave them unchanged.
  7. Hit Deploy. On a testnet it runs right away. On a mainnet you'll first confirm a short disclaimer.
Mainnet deployment

Deploying to a mainnet is permanent, costs real gas and needs a paid Toolblox plan. (The Redbelly network can be deployed to without a paid subscription.)

After deploying​

Once deployed you can:

  • Launch / Run — open the auto-generated Asset Dashboard and start using your workflow.
  • View deployment history — every deployment is listed with its network and date, and a link to view the contract on the blockchain explorer.
  • View code / spec — inspect the generated contract source (on a paid plan) or export the workflow as a Toolblox Spec.
  • Re-deploy — made a change? Deploy again; each deployment is recorded separately.

Choosing a network​

Toolblox supports many EVM networks (and Near). For a side-by-side of what each one supports, see the blockchain feature matrix. Want fee-free transactions for your users? See Gasless transactions.
