Once your crypto application is built inside Famous.ai, the next step is deploying it to the blockchain. Deployment is the moment when your smart contract becomes a permanent part of the blockchain network. From that point forward, users can interact with your token and application.
This guide explains how to launch your project safely and test it before sharing it publicly.
Step 1: Choose Your Blockchain Network
When deploying your smart contract, Famous.ai asks you to select a blockchain network. Your choice determines transaction fees, network speed, ecosystem compatibility, and where your token will permanently live.
There are two categories of networks:
Test Networks (TestNet)
TestNet environments simulate real blockchain activity using fake tokens.
No financial risk
Safe environment for debugging
Ability to test the user experience
Note: Developers commonly test their projects several times on TestNet before deploying to the live network.
Main Networks (MainNet)
MainNet networks represent the real blockchain. Transactions require real cryptocurrency, and your token becomes permanently accessible. Common options include:
Ethereum MainNet: The original network. Extremely secure and trusted, but can have high gas fees during busy periods.
Base MainNet: A Layer 2 network built on Ethereum. Offers low fees, faster transactions, and a growing developer ecosystem.
Polygon MainNet: A widely adopted Ethereum scaling network with inexpensive transactions and strong ecosystem support.
If you are unsure which network to choose, start with TestNet for experimentation.
Step 2: Deploy Your Smart Contract
Once you select the network, Famous.ai will prompt you to deploy the contract.
When you click Deploy Contracts:
MetaMask opens a transaction confirmation window.
The wallet shows the gas fee required for deployment.
Review the transaction details.
Click Confirm.
Your wallet signs the transaction and sends it to the blockchain. After the transaction processes, your smart contract becomes permanently active. Congratulations—your cryptocurrency now exists on the blockchain!
Step 3: Find Your Token Contract Address
Every smart contract receives a unique blockchain identifier called a contract address. This address allows users to locate your token, wallets to display token balances, and block explorers to track transactions.
Inside Famous.ai:
Go to the Contracts section to locate your deployed contract.
Copy the contract address.
Alternatively, if your app UI is configured to show it, you can copy it directly from your new dashboard. If you cannot see it immediately, you can ask the AI assistant in the project: "Show me my token contract address."
Keep this address safe because it identifies your token across the blockchain ecosystem.
Step 4: Verify Your Token on a Block Explorer
Block explorers allow anyone to view blockchain activity. Examples include Etherscan (Ethereum), BaseScan (Base network), and PolygonScan (Polygon).
To verify your token:
Open the block explorer for your network.
Paste your contract address into the search bar.
View the contract page.
You will see the total token supply, the contract creation transaction, token transfers, and wallet interactions. This confirms that your token exists on the blockchain.
Step 5: Test the Buying Experience
Before announcing your project publicly, test the user experience from the perspective of a real user. The easiest method uses a second wallet.
Create a test environment by:
Opening a new browser profile.
Installing MetaMask again.
Creating a second wallet and connecting it to the same network.
Next:
Visit your Famous.ai app.
Connect the second wallet.
Attempt to buy tokens.
This simulates a real user interacting with your application. Testing helps confirm that the wallet connection works, token purchases execute correctly, and balances update properly.
Step 6: Approve the Transaction
When purchasing tokens, MetaMask prompts the user to approve the transaction.
The wallet will display:
The amount of cryptocurrency required
Gas fees
The receiving smart contract
After reviewing the details, click Confirm. The blockchain processes the transaction and records it permanently. If everything works correctly, the purchase should succeed within seconds or minutes depending on network speed.
Step 7: Verify the Transaction
After completing a purchase, confirm that the transaction was recorded correctly.
Inside MetaMask, open the Activity tab, select the recent transaction, and copy the Transaction ID. Paste the Transaction ID into your block explorer.
This displays the full on-chain record, including the sender wallet, receiving contract, token transfer amount, and confirmation status. This verification step ensures your contract behaves correctly.
Step 8: Add Your Token to MetaMask
New tokens often do not appear automatically in MetaMask. You can add them manually.
Inside MetaMask:
Click the three dots menu.
Select Import Tokens.
Switch to the Custom token tab.
Paste your contract address.
MetaMask will automatically detect the token symbol and decimal. Click Next.
Click Import. Now you and your users can see and manage the token balance directly from the wallet.
Your Crypto Project Is Live
Launching a crypto project used to require an experienced blockchain development team and months of work. Today, platforms like Famous.ai automate much of the process by generating smart contracts, building the user interface, and managing blockchain deployment.
By following this guide, you have:
Created a crypto application
Deployed a smart contract
Launched a live token
Tested real transactions
Verified blockchain activity
Your project is now ready for the next phase: growing your community and attracting users. From here, the focus shifts from development to adoption.
