# ThirdWeb Contracts SDK Implementation Guide (v5) ## Introduction This guide explains how to integrate the ThirdWeb Contracts SDK (v5) into a Next.js + TypeScript application for creating, deploying, and managing smart contracts. ## Overview The ThirdWeb Contracts SDK provides tools to streamline Web3 development, including: - **Contract Deployment and Interaction**: Deploy and interact with smart contracts easily. - **Wallet Integration**: Connect and manage crypto wallets securely. - **Utilities**: Use hooks and functions for transaction management and contract handling. - **Contract Library**: Access pre-built, audited smart contracts. ## Critical Implementation Notes -**CRITICAL**: You are to make sure to always install the required packages first! -**CRITICAL**:You are to always implement components in this order: 1. Set up the providers and root layout first 2. Then implement other components that depend on it -**CRITICAL**: You are to create and environment variable (.env.local) to store sensitive credentials (e.g., NEXT_PUBLIC_THIRDWEB_CLIENT_ID and NEXT_PUBLIC_THIRDWEB_SECRET_KEY) in environment variables. -**CRITICAL**: Define wallet configurations directly in the ConnectButton component (see WalletConnect component). -**CRITICAL**: You are to use the provided TypeScript interfaces and error-handling patterns for consistency and type safety. -**CRITICAL**: You are to follow the UI implementation as closely as possible for consistency in rebuilding the app. -**CRITICAL**: You are to make sure to build the Home component (page.tsx) and ModularContractDeployer component (ModularContractDeployer.tsx) and all other components/modules with the provided interfaces/UI setup, making sure to include the coreType and subCategory options selections always within the ModularContractDeployer component and also alwaysshowing the ModularContratDepoloyer and PrebuiltContractDeployer components on the Home component. ## Environment Variables Make sure to create a '.env.local' file and store the following environment variables there. Add them to your `.env.local` file: ``` THIRDWEB_CLIENT_ID=2f654d0179741f6776fa108a9683038e ``` ## Provider Configuration ```tsx ``` ## Type Definitions ```typescript // app/types.ts import { Chain, Module, ContractEvent } from 'thirdweb'; // Type for the chains array in Home component export interface ChainOption { name: string; chain: Chain; } // Type for the activeComponent state in Home component export type ActiveComponent = 'modular' | 'prebuilt' | 'view' | null; export type CoreType = 'ERC20' | 'ERC721' | 'ERC1155'; export type Subcategory = | 'Token' | 'Token Drop' | 'NFT Collection' | 'NFT Drop' | 'Open Edition' | 'Edition' | 'Edition Drop'; export interface CoreSubcategories { ERC20: Subcategory[]; ERC721: Subcategory[]; ERC1155: Subcategory[]; } export interface ModularContractDeployerProps { prefilledCoreType?: CoreType; prefilledSubcategory?: Subcategory; prefilledModules?: Module[]; onBack?: () => void; isPrefilled?: boolean; // New prop to indicate prefilled mode } export interface PopularContract { name: string; description: string; coreType: CoreType; subcategory: Subcategory; modules: Module[]; } export interface PrebuiltContractDeployerProps { onBack?: () => void; } ``` ## Core Components/Modules ### Component/Module 1: Wallet Connection #### Overview Renders a button to connect a wallet using ThirdWeb’s `ConnectButton`. #### Basic Usage ```tsx // components/WalletConnect.tsx 'use client'; import { ConnectButton } from 'thirdweb/react'; import { inAppWallet, createWallet } from 'thirdweb/wallets'; import { createThirdwebClient } from 'thirdweb'; import { sepolia, baseSepolia, ethereum, polygon } from 'thirdweb/chains'; const client = createThirdwebClient({ clientId:process.env.THIRDWEB_CLIENT_ID || '2f654d0179741f6776fa108a9683038e' }); const wallets = [ createWallet('io.metamask'), createWallet('com.coinbase.wallet'), createWallet('me.rainbow'), createWallet('io.rabby'), createWallet('io.zerion.wallet'), ]; interface WalletConnectProps { onConnect?: () => void; // Optional callback for when wallet connects } export default function WalletConnect({ onConnect }: WalletConnectProps) { return ( ); } ``` #### Props/Configuration 1. **Required Props** - none required 2. **Optional Props** - none #### Implementation Notes - You are to ensure the NEXT_PUBLIC_THIRDWEB_CLIENT_ID environment variable is set correctly. - You are to ensure the NEXT_PUBLIC_THIRDWEB_SECRET_KEY environment variable is set correctly. ### Component/Module 2: Home (Welcome Page) #### Overview Displays the main page with options to deploy a modular contract, deploy a prebuilt contract, or view an existing contract. #### Basic Usage ```tsx // app/page.tsx 'use client'; import { useState } from 'react'; import { useActiveAccount } from 'thirdweb/react'; import { sepolia, baseSepolia, ethereum, polygon } from 'thirdweb/chains'; import WalletConnect from './components/WalletConnect'; import ModularContractDeployer from './components/ModularContractDeployer'; import PrebuiltContractDeployer from './components/PrebuiltContractDeployer'; import { ChainOption, ActiveComponent, } from '../app/types'; export default function Home() { const activeAccount = useActiveAccount(); const address = activeAccount?.address; const [activeComponent, setActiveComponent] = useState(null); const [viewContractAddress, setViewContractAddress] = useState(''); const [viewContractChain, setViewContractChain] = useState(sepolia); const [viewContractError, setViewContractError] = useState(''); const [showConnectModal, setShowConnectModal] = useState(false); const [modalContractType, setModalContractType] = useState(null); const chains = [ { name: 'Sepolia (Testnet)', chain: sepolia }, { name: 'Base Sepolia (Testnet)', chain: baseSepolia }, { name: 'Ethereum Mainnet', chain: ethereum }, { name: 'Polygon Mainnet', chain: polygon }, ]; // Function to reset back to card view const resetView = () => { setActiveComponent(null); setViewContractAddress(''); setViewContractChain(sepolia); setViewContractError(''); }; / Function to handle contract deployment const handleDeploy = (contractType:'string') => { if (!address) { setShowConnectModal(true); setModalContractType(contractType); } else { setActiveComponent(contractType as as ActiveComponent) } }; // Callback for when wallet connects const handleWalletConnect = (contractType?:'string') => { setShowConnectModal(false); // Close the modal if (contractType) { handleDeploy(contractType); // Trigger deployment only if contractType is provided } }; // Use useEffect to close the modal when address becomes available useEffect(() => { if (address && showConnectModal) { setShowConnectModal(false); // Close the modal if the user is connected if (modalContractType) { setActiveComponent(modalContractType as ActiveComponent); // Set the active component } } }, [address, showConnectModal, modalContractType]); // Use useEffect to reset to home page when wallet disconnects useEffect(() => { if (!address && activeComponent) { setActiveComponent(null); // Reset to home page if disconnected } }, [address, activeComponent]); return (

#### Props/Configuration

1. **Required Props**
   - none
2. **Optional Props**

- `preflledCoreType` (CoreType): Preselects the contract type (ERC20, ERC721, ERC1155). Defaults to 'ERC20'
- `prefilledSubcategory` (Subcategory): Preselects the contract subcategory. Defaults to 'Token'
- `prefilledModules` (Module[]): Preselects the modules to include. Defaults to undefined.
- `onBack` (() => void): Callback to navigate back to the previous view. Defaults to undefined

#### Implementation Notes

- **CRITICAL**: You are to make sure to build the ModularContractDeployer component (ModularContractDeployer.tsx) with the provided interfaces/UI setup, making sure to include the coreType and subCategory options selections and all other input options as indicated in the UI part of the code always 
- Test deployment on different chains, especially testnets like Sepolia, to avoid high gas costs.
- Validate addresses (e.g., ownerAddress, royaltyRecipient) to ensure they are valid Ethereum addresses.

    useState<PopularContract | null>(null);

if (selectedContract) {
    return (
      <ModularContractDeployer
        prefilledCoreType={selectedContract.coreType}
        prefilledSubcategory={selectedContract.subcategory}
        prefilledModules={selectedContract.modules}
        onBack={() => setSelectedContract(null)}
        isPrefilled={true} // Pass isPrefilled to disable select boxes
      />
    );
  }

}
```

#### Props/Configuration

1. **Required Props**
   - none
2. **Optional Props**
   - `onBack` (() => void): Callback to navigate back to the previous view. Defaults to undefined

#### Implementation Notes

- - **CRITICAL**: You are to make sure to build the PrebuiltContractDeployer component (PrebuiltContractDeployer.tsx) with the provided interfaces/UI setup, making sure to include the coreType and subCategory options selections and all other input options as indicated in the UI part of the code always 
- Aligns styling with other components (light theme: bg-gray-100, text-black).
- The modules in popularContracts have placeholder values (e.g., primarySaleRecipient: ''). These are set dynamically in ModularContractDeployer.

### Component/Module 5: View Contract

#### Overview

Displays deployed contract details

#### Basic Usage

```tsx
import { Chain } from 'thirdweb/chains';

interface ViewContractProps {
  contractAddress: string;

  contractAddress,
  chain,
  name,
  imageUrl,
  creator,
  onBack,
}: ViewContractProps) {
  // Function to copy address to clipboard
  const copyToClipboard = (text: string) => {
    navigator.clipboard.writeText(text).then(() => {
      alert('Address copied to clipboard!');
    });
  };
  // Function to get Etherscan link based on chain
  const getEtherscanLink = () => {
    const chainId = chain.id;
    let baseUrl = '';
    if (chainId === 11155111) {
      // Sepolia
      baseUrl = 'https://sepolia.etherscan.io';
    } else if (chainId === 1) {
      // Ethereum Mainnet
      baseUrl = 'https://etherscan.io';
    } else {
      // Default to Etherscan mainnet if chain is unknown
      baseUrl = 'https://etherscan.io';
    }
    return `${baseUrl}/address/${contractAddress}`;
  };

return (
    <div className="max-w-4xl mx-auto px-4 py-8">

          </div>
        </div>
      </div>
    </div>
  );
}
```
### Props/Configuration

1. **Required Props**
 - `contractAddress` (string): The address of the deployed contract.
 - `chain` (Chain): The chain on which the contract is deployed (from thirdweb/chains).
 - `name` (string): The name of the contract.
 - `imageUrl` (string): URL of the contract's image.
 - `creator` (string): The address of the contract creator.
 - `onBack` (function): Callback to navigate back to the previous view.
2. **Optional Props**
   - none
#### Implementation Notes

- The contract address is clickable to copy to the clipboard, with a confirmation alert.
- The Etherscan link is dynamically generated based on the chain (e.g., Sepolia uses sepolia.etherscan.io).
- If no image is provided, a placeholder is shown.
- Ensure the chain prop matches the chain used for deployment to generate the correct Etherscan link.
- Best practice: Test the Etherscan link generation for all supported chains.
- Common pitfall: Ensure the imageUrl is a valid URL to avoid broken images.

## Hooks

This section documents the ThirdWeb React hooks used in the application to manage wallet connections and contract interactions.

### Hook 1: useActiveAccount

This hook provides the currently connected wallet account and its details.

#### Usage

```typescript
import { useActiveAccount } from 'thirdweb/react';

export default function WalletStatus() {
  const activeAccount = useActiveAccount();
  const address = activeAccount?.address;
  if (!address) {
    return <div>No wallet connected.</div>;
  }
  return <div>Connected wallet: {address}</div>;
}
```

#### Parameters

- none

#### Returns

- `activeAccount` (object | undefined ): The connected wallet account object, or undefined if no wallet is connected.
  - `address` (string): The wallet address.
  - Other properties may be available depending on the wallet provider.

## Root Layout Integration

Show how to integrate the SDK at the root level:

```tsx
// app/layout.tsx
import './globals.css';
import { ThirdwebProvider } from 'thirdweb/react';
import { createThirdwebClient } from 'thirdweb';
import { sepolia, baseSepolia, ethereum, polygon } from 'thirdweb/chains';

const client = createThirdwebClient({
  clientId:'process.env.THIRDWEB_CLIENT_ID || '2f654d0179741f6776fa108a9683038e',
});

export default function RootLayout({
  children,
}: Readonly<{
  children: React.ReactNode;
}>) {
  return (
    <html lang='en'>
      <body>
        <ThirdwebProvider
          client={client}
          activeChain={sepolia}
          supportedChains={[sepolia, baseSepolia, ethereum, polygon]}
        >
          {children}
        </ThirdwebProvider>
      </body>
    </html>
  );
}
```

## Type Safety and Error Handling

### Type Guards

Use type guards to safely handle responses from ThirdWeb SDK functions, which may return error objects.

```typescript
export function isErrorResponse(
  response: unknown
): response is { error: string } {
  return (
    response !== null && typeof response === 'object' && 'error' in response
  );
}
```

### Error Handling Pattern

```typescript
try {
  const result = await sdkFunction(params);
  if (isErrorResponse(result)) {
    throw new Error(result.error);
  }
  // Process successful result
} catch (error) {
  // Handle error appropriately
  console.error('SDK Error:', error);
}
```

## Best Practices

- You are to always validate contract addresses and parameters before making calls.
- You are to maintain a clear separation between UI components and contract logic.
- You are to use environment variables for all sensitive configurations.
- You are to implement robust error handling to manage blockchain transaction failures and network issues.

## Advanced Usage

### Custom Configurations

```typescript
const customConfig = {
  gasLimit: 'auto',
  pollingInterval: 15000,
 };
```

### Integration Patterns

- Decoupled Architecture: Separate contract logic from UI components.
- Hook-based Interactions: Use custom hooks to manage state and side effects.
- Dynamic Wallet Integration: Configure wallet options directly within UI components

## Utilities and Helpers

The SDK provides several utility functions to ease common tasks:

```typescript
import { parseUnits, formatUnits } from '@thirdweb-dev/contracts/utils';

// Example: Convert tokens to the correct units
const formatted = parseUnits('1.0', 18);
```

## Common Workflows

Provide examples of common implementation workflows:

1. Connect Wallet and Deploy a Prebuilt Contract
   - Click "Deploy" on the "Popular Contract" card.
   - Connect your wallet via the modal.
   - Select a contract (e.g., "Token").
   - The ModularContractDeployer form opens with coreType and subcategory disabled.
   - Fill in the form and deploy the contract.
2. Deploy a Modular Contract
   - Click "Deploy" on the "Modular Contract" card.
   - Connect your wallet if not already connected.
   - Configure the contract type, subcategory, and other settings.
   - Deploy the contract and view the deployed address.
3. Error Handling
   - If deployment fails (e.g., invalid input, network error), an error message is displayed.
   - Example: "Valid owner address is required" if the owner address is invalid.

## Testing Considerations

- You are to write unit tests for each component and hook.
- You are to use mocking libraries to simulate SDK responses.
- You are to include itesting on a testnet (e.g., Sepolia)
