Smart Contract Publish

Deploy your smart contract to Solana devnet or mainnet directly from Noah.

Overview

Use Smart Contract Publish to deploy your smart contract (program) to Solana and get the key outputs you need to integrate it elsewhere:

• Contract address / Program ID
• Transaction hash

There are two common deployment scenarios in Noah:

• Case 1 — Standalone smart contract project: you’re working in a smart-contract-only project and deploy from the top-bar Deploy button.
• Case 2 — Smart contract inside a DApp: you’re building a DApp and deploy the smart contract either from chat actions or from the Publish modal’s Smart Contract tab.

After a successful deployment, copy and save your Program ID and Transaction Hash. You’ll often need them to configure your frontend and verify on-chain activity later.

Prerequisites

• Run tests first (recommended): make sure your contract compiles and tests pass before deploying.
• Start with Devnet: deploy to Solana Devnet first to validate behavior safely before deploying to Solana Mainnet.
• Be ready to back up addresses: after deployment, Noah shows the contract address and transaction hash. Save them somewhere safe for later use.

Case 1: Publish a standalone smart contract project

This flow applies when your project is focused only on the smart contract (no DApp UI publishing involved).

1. Open the Deploy flow

   From your project, click Deploy in the top bar.

   
2. Download the deployment keypair and IDL

   Before deployment, Noah will show you the contract keypair and the generated IDL file.

   1. Download and securely store the keypair.json file. Noah does not retain this data.

   2. Download the IDL file (*.idl.json) so you can use it later to integrate the program.

   3. Check the confirmation box to confirm you have stored the keypair, then click Next.

      
3. Provide initialization parameters (if prompted)

   Some contracts require initial configuration values before deployment can proceed. If Noah prompts you with an Initialize Configuration step:

   1. Fill in the required fields (these vary by contract).

   2. Click Next.

      
4. Choose a network and review the deployment wallet

   In the Deploy Contract modal:

   1. Select the network:

      • Solana Devnet for testing
      • Solana Mainnet for production

   2. Review the Deployment Wallet (Auto-Generated) details:

      • The wallet address Noah will use for the deployment
      • The wallet balance, which must be sufficient for deployment fees

   3. Click Deploy.

      
5. Wait for deployment to complete

   Noah deploys your contract via a remote server. Keep the modal open while the deployment runs.

   
6. Confirm the deployed addresses

   When deployment succeeds, Noah shows:

   • Contract Address (Program ID)
   • Transaction Hash

   Copy and save both values. Confirm the backup checkbox, then click Done.

   

Case 2: Publish the smart contract inside a DApp

If your smart contract is part of a DApp project, you have two ways to deploy it.

1. Option A — Deploy via chat

   From the chat panel, use the deployment action (for example Deploy to Devnet) and wait for the deployment to finish. This is a convenient path when you are iterating quickly and want to deploy without opening additional modals.

2. Option B — Deploy via the Publish modal

   1. Open Publish to launch the Publish Your DApp modal.

   2. Switch to the Smart Contract tab.

   3. Review the status for each network:

      • Solana Devnet will show as Deployed when available and display the program ID.
      • Solana Mainnet will show as Not Deployed until you publish there.

   4. Use Redeploy Smart Contract to deploy again after contract changes.

      

Troubleshooting

Deployment wallet has insufficient balance

If the Deployment Wallet (Auto-Generated) balance is too low, fund it for Devnet or ensure you have sufficient funds for Mainnet before deploying.

Devnet vs Mainnet mismatch

If your app is pointing at Devnet but you deployed to Mainnet (or vice versa), switch to the correct network and copy the correct Program ID.

Initialization required but missing

If your contract requires initialization parameters, provide them in the Initialize Configuration step before continuing.

Deployment appears stuck

Close the modal and try Deploy again, or use Redeploy Smart Contract from the DApp Publish modal if you are in a DApp project.

Next steps

• If this contract is part of a DApp, publish the DApp UI after the contract is deployed. See DApp Publish.
