Introduction

Understand the role of Naven x402 facilitator

Naven x402 facilitator is a hosted service that enables on-chain payment verification and settlement for HTTP resources leveraging on the x402 standard. It verifies payment payloads submitted by clients (buyers) and settles the corresponding transactions on-chain on behalf of servers (sellers).

Facilitator Responsibilities

A facilitator is responsible for verifying payments, executing on-chain settlements, and maintaining the infrastructure for reliable and observable payment processing, without holding funds or acting as a custodian.

Payment verification: Validate client-submitted payment payloads against server-declared parameters to ensure integrity, authenticity, and replay protection.

Payment settlement: Perform on-chain execution of verified payments and monitor transaction confirmations until completion.

API interface: Expose secure /verify and /settle endpoints that align with x402 compatible request/response specifications.

Infrastructure maintenance: Manage reliable RPC, wallet, and network connectivity across supported chains.

System monitoring: Maintain operational visibility and reliability through logging, rate limiting, alerting, and related mechanisms.

Response handling: Return clear and structured verification or settlement outcomes for server-side fulfillment logic.

Operational Advantages

By providing a uniform API that abstracts blockchain complexity, Naven Facilitator eliminates the need for servers to manage direct blockchain connectivity or implement native payment verification logic, reducing infrastructure overhead and enabling accurate, real-time transaction validation across merchants, applications, and resource servers.

Operational efficiency: Servers are freed from managing blockchain nodes or implementing custom verification logic

Protocol standardization: Consistent verification and settlement across supported schemes and networks

Streamlined integration: Seamless payment support onboarding for applications with minimal blockchain development

Shared infrastructure: Unified /verify and /settle API that supports merchants and applications
