Network configuration snippet

export const teqoin = {
  id: 420377,
  name: 'TeQoin L2',
  network: 'teqoin',
  nativeCurrency: {
    name: 'Ether',
    symbol: 'ETH',
    decimals: 18,
  },
  rpcUrls: {
    default: {
      http: ['https://rpc.teqoin.io'],
    },
  },
};

​

Good defaults for new teams

1. Use Foundry for contracts.
2. Use React + Vite for the frontend.
3. Use ethers for the first integration.
4. Add Wagmi only when you need richer wallet UX.
