Biconomy MEE

Enable gasless transactions with Biconomy Meta-Transactions

Integrate OZZOBiT with Biconomy's Meta-Transaction Enablement Engine (MEE) to enable gasless crypto purchases. Users can buy crypto without needing to hold ETH or native tokens for gas fees.

What is Biconomy MEE?

Biconomy MEE is a relayer infrastructure that enables meta-transactions (gasless transactions) on EVM-compatible blockchains. When combined with OZZOBiT, users can complete on-ramp transactions without needing to pay for gas separately.

How It Works

User Initiates Purchase

User selects to buy cryptocurrency in your application. They don't need any existing crypto or gas tokens.

OZZOBiT Processes Payment

User pays with fiat (card/bank). OZZOBiT processes the payment and prepares the crypto transfer.

Biconomy Relays Transaction

Instead of the user paying gas, Biconomy's relayer network submits the transaction and covers the gas cost. The gas fee is bundled into the fiat price.

Crypto Delivered

Crypto arrives in the user's wallet without them ever needing to handle gas fees.

Integration Setup

Step	Action
1	Sign up at biconomy.io and create a project
2	Get your Biconomy API Key and Dashboard ID
3	Contact OZZOBiT support to enable Biconomy MEE integration
4	Configure your dApp smart contract for meta-transactions
5	Add Biconomy parameters to your widget URL or API calls
6	Test on testnet before deploying to mainnet

Widget Configuration

biconomy-widget.jsjavascript

// Widget URL with Biconomy MEE enabled
const params = new URLSearchParams({
  apiKey: 'YOUR_OZZOBiT_API_KEY',
  productsAvailed: 'BUY',
  network: 'ethereum',
  defaultCryptoCurrency: 'USDC',
  walletAddress: '0xUserWalletAddress...',
  
  // Biconomy configuration
  biconomyEnabled: 'true',
  biconomyApiKey: 'YOUR_BICONOMY_API_KEY',
  biconomyDashboardId: 'YOUR_DASHBOARD_ID',
})

const url = `https://OZZOBiT.com/global?${params.toString()}`

// The user experience:
// 1. User clicks "Buy USDC"
// 2. Pays $100 with credit card  
// 3. Receives USDC in wallet (no gas needed!)
