Blockchain Payment Facilitator Workflow

This comprehensive n8n workflow acts as a facilitator for blockchain-based payments, enabling secure token transfers and validation via webhooks. It integrates with the x402 API and handles various steps including payment simulation, verification, and settlement. The workflow begins with webhook triggers for ‘/verify’ and ‘/settle’ endpoints, where it authenticates and validates payment payloads. It supports multiple blockchain networks and tokens, with configuration for supported assets and networks. The core process involves parsing payment signatures, verifying token and chain compatibility, and then simulating or executing blockchain transactions through the 1Shot API. Response nodes ensure proper communication back to clients, indicating success or specific errors. It is ideal for automating and securing cross-chain payments in decentralized applications or payment gateways.
