Intent & Widget
Your backend creates a purchase intent via our API. The widget uses the resulting client secret to securely fetch pricing and cryptographic vouchers for the transaction.
Customer Signature
The customer's wallet signs the transaction, calling the smart contract directly. Shake DeFi acts strictly as a decentralized facilitator.
Settlement & Webhooks
Upon successful on-chain purchase, the smart contract settles funds to your merchant wallet immediately. Our backend detects this and sends a webhook to your system.
