🚀 Quick Start

import { PieverseReceipt } from '@pieverse/receipt';

function App() {
  return (
    <PieverseReceipt
      tx="0xe74240d638ae8d8407cc7a3d2a9b492dfb2c9ea9545c86fb048157146563b909"
      chain="bsc"
      brandConfig={{
        partnerName: "My DApp",
        primaryColor: "#667eea"
      }}
      onDownload={(success) => {
        console.log('Receipt downloaded:', success);
      }}
    />
  );
}

That's it! Your users can now download professional receipts for their blockchain transactions.

Note: The component works with simple wallet-to-wallet token transfers. Complex contract interactions may not be supported.

Basic Usage

<PieverseReceipt tx="0xabcdef..." chain="bsc" />

With Custom Branding

<PieverseReceipt
  tx="0xe74240d638ae8d8407cc7a3d2a9b492dfb2c9ea9545c86fb048157146563b909"

With Callbacks

<PieverseReceipt
  tx="0xabcdef..."
  chain="bsc"
  onGenerate={(invoice) => {
    console.log('Invoice generated:', invoice);
    // Track analytics, update UI, etc.
  }}
  onDownload={(success, error) => {
    if (success) {
      showSuccessToast('Receipt downloaded!');
    } else {
      showErrorToast(`Failed: ${error}`);
    }
  }}
/>

With Custom Tokens

<PieverseReceipt
  tx="0xabcdef..."
  chain="bsc"
  customTokens={[
    {
      address: "0x0E09FaBB73Bd3Ade0a17ECC321fD13a19e81cE82",
      symbol: "CAKE",
      decimals: 18,
      name: "PancakeSwap Token"
    },
    {
      address: "0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d",
      symbol: "USDC",
      decimals: 6,
      name: "USD Coin"
    }
  ]}
/>

With Custom RPC

<PieverseReceipt
  tx="0xabcdef..."
  chain="bsc"
  rpcUrl="https://your-custom-rpc-endpoint.com"
  customTokens={myTokens}
/>

With Custom Loading State

<PieverseReceipt
  tx="0xabcdef..."
  loadingText="Fetching receipt..."
  // OR use a custom component
  loadingComponent={
    <div className="flex items-center gap-2">
      <Spinner /> Generating...
    </div>
  }
/>

🎨 Customization

Brand Configuration

Customize the receipt appearance with your brand:

interface BrandConfig {
  partnerName?: string;        // Your DApp name
  logoUrl?: string;            // URL to your logo
  primaryColor?: string;       // Primary brand color (hex)
  secondaryColor?: string;     // Secondary color (hex)
  backgroundColor?: string;    // Background color
  textColor?: string;          // Text color
}

Custom Tokens

Support custom ERC20 tokens beyond the built-in USDT, BUSD, and USDC:

interface TokenConfig {
  address: string;    // Token contract address
  symbol: string;     // Token symbol (e.g., "CAKE")
  decimals: number;   // Token decimals (usually 18)
  name?: string;      // Optional token name
}

// Example usage
const myTokens: TokenConfig[] = [
  {
    address: "0x0E09FaBB73Bd3Ade0a17ECC321fD13a19e81cE82",
    symbol: "CAKE",
    decimals: 18,
    name: "PancakeSwap Token"
  }
];

<PieverseReceipt tx="0x..." customTokens={myTokens} />

How it works:

• The component automatically detects if the transaction involves your custom tokens
• Token address matching is case-insensitive
• Falls back to default tokens (USDT, BUSD, USDC) if not in custom list
• Shows "UNKNOWN" for unrecognized tokens
• Supports custom decimals for accurate amount formatting

Button Variants

Choose from three built-in variants or use custom styling:

• button - Standard button (default)
• icon - Compact icon button
• link - Text link style

🌍 Supported Chains

Note: Chain parsers are implemented for all networks. Component integration for non-BSC chains is in progress.

📚 API Reference

<PieverseReceipt>

Main component for receipt generation.

Props

Utility Functions

import {
  parseBscTransaction,     // Parse a BSC transaction
  downloadReceiptPDF,      // Generate and download PDF
  formatAddress,           // Format wallet addresses
  formatCurrencyAmount,    // Format amounts with proper decimals
  getExplorerLink,         // Get block explorer link
} from '@pieverse/receipt';

🏗️ Advanced Usage

Headless API

For custom implementations without the UI component:

import { parseBscTransaction, downloadReceiptPDF } from '@pieverse/receipt';

async function customDownload(txHash: string) {
  // Parse transaction
  const invoice = await parseBscTransaction(txHash);
  
  // Generate and download PDF
  const result = await downloadReceiptPDF(
    invoice,
    { partnerName: 'My DApp' },
    true  // Include branding
  );
  
  if (result.success) {
    console.log('Downloaded via:', result.method);
  }
}

Transaction Parser

Parse transactions without generating receipts:

import { parseBscTransaction } from '@pieverse/receipt';

const invoice = await parseBscTransaction('0xabcdef...');
console.log(invoice);
// {
//   id: '0xabcdef...',
//   amount: '100.00',
//   currency: 'USDT',
//   creatorAddress: '0x...',
//   recipientAddress: '0x...',
//   // ... more fields
// }

🎯 Use Cases

• DeFi Protocols - Receipts for swaps, stakes, and yields
• NFT Marketplaces - Purchase receipts for tax reporting
• DAOs - Contributor payment receipts
• Payroll Apps - Employee payment documentation
• Payment Gateways - Merchant transaction receipts

⚠️ Important Notes

Transaction Types

The component is designed for simple payment transactions:

• ✅ Wallet-to-wallet token transfers (USDT, USDC, BNB, etc.)
• ✅ Direct payment transactions
• ❌ Complex contract interactions (DEX swaps, DeFi protocols)
• ❌ Contract deployment transactions

If you see errors about "contract interaction, not a simple payment", ensure you're using a direct transfer transaction.

Currently Supported

• BSC: Fully functional with component integration
• Other Chains: Parsers implemented, component integration pending

Check the example website (example/) for working demonstrations.

🗺️ Roadmap
