The Checkout component automatically detects which networks are supported based on your API’s X402 payment requirements. Users can switch networks directly in their wallet if needed.

Different networks have varying gas fee structures:

  • Ethereum: Higher fees, most secure
  • Layer 2s (Arbitrum, Base, Optimism): Lower fees, fast transactions
  • Avalanche: Very low fees, fast finality
  • BNB Smart Chain: Low fees, high throughput

Choose networks based on your use case and user preferences for transaction costs.
