Quick Start

The fastest way to bootstrap a TAC project is using our CLI tool:

npx create-tac-app my-tac-project

This will create a new directory with a fully configured TAC project.

Make sure you have:

• Node.js v14.16.0 or higher
• An Ethereum wallet with some testnet TAC tokens for deployment
• TON wallet for testing (Tonkeeper or TON Space recommended)

You can get testnet TAC tokens from the TAC Testnet Faucet.

Navigate to the contracts directory and deploy them to the TAC testnet:

cd my-tac-project/contracts
npm install
npx hardhat run scripts/deploy.js --network tacTestnet

Take note of the deployed contract addresses displayed in the console: - SimpleMessage contract address - MessageProxy contract address

Open lib/contract_address.ts in your project and update it with your deployed contract addresses:

export const CONTRACT_ADDRESSES = {
  simpleMessage: "0xYourSimpleMessageAddress",
  messageProxy: "0xYourMessageProxyAddress"
};

Return to the project root and start the Next.js development server:

cd ..
npm run dev

Your TAC application is now running at http://localhost:3000.

Open your application in the browser and connect your TON wallet using the TON Connect button. The starter app includes a basic messaging example that demonstrates cross-chain communication from TON to EVM.

Now you can start building your hybrid dApp by:

• Modifying the smart contracts in the contracts directory
• Updating the frontend in the pages and components directories
• Leveraging the TAC SDK’s cross-chain messaging capabilities

The starter app includes reusable components for TON wallet connection and TAC SDK integration.
