// 1. Set up community
const community = createCommunityClient({...});
await community.registerCommunity({ name: 'MyDeFi' });

// 2. Deploy community token
const tokenAddress = await community.deployXPNTs({
  name: 'MyDeFi Points',
  symbol: 'MDP',
  initialSupply: parseEther('1000000'),
});

// 3. Enable gasless transactions for users
const user = createEndUserClient({...});
const eligible = await user.checkEligibility(communityAddress);

// 4. Users can interact without gas fees
if (eligible) {
  await sendGaslessTransaction();
}
