Integrate zkpay's permissionless blockchain payment infrastructure into your applications
Initialization & Setup
Create a payment channel to accept cryptocurrency payments with zkpay. No account or API keys are needed—just provide your merchant address and payment details.
Note: The API expects amounts in the smallest unit (e.g., wei or token decimals), while the SDK uses human-readable values (e.g., "100.00" USDC).
