Pieverse Partners with Questflow: Embedding x402b for Autonomous AI Payments on BNB Chain

Pieverse and Questflow have partnered to integrate x402b, Pieverse’s gasless payment protocol, into the BNB Chain ecosystem, enabling seamless autonomous AI payments for agents and services.

Partnership Overview: AI Agents and x402b Integration

Pieverse, a Web3 payment infrastructure startup, and Questflow, an AI agent coordination platform, have collaborated to embed x402b—their extended x402 protocol—into BNB Chain. This integration allows AI agents to perform gasless, auditable transactions for APIs, data, and computations, solving BNB Chain’s EIP-3009 limitations with pieUSD, a 1:1 USDT wrapper. The partnership accelerates agentic commerce, where AI autonomously pays for resources without human intervention.

x402b Protocol: Gasless and Compliant Payments

x402b upgrades the original x402 HTTP payment standard with:

• Gas-Free USDT0 Transfers: EIP-3009 support via pieUSD for zero-fee sends.
• Audit-Ready Receipts: Jurisdiction-specific, immutable storage on BNB Greenfield for compliance.
• Facilitator Layer: Abstracts multi-chain complexity for consistent verification and settlement.

This makes BNB Chain enterprise-ready for AI payments, reducing costs by 90% and enabling verifiable, privacy-preserving flows.

• Key Benefits: Sub-second finality; no OAuth/API keys.
• Ecosystem Impact: Supports 15+ chains; $800M+ x402 token value.
• Funding: $10M total, including CMS Holdings pre-TGE.

Questflow Integration: AI Agent Commerce

Questflow’s AI coordination platform leverages x402b for agent-to-agent transactions, automating payments for workflows like data queries or computations. This creates a “trust layer” for AI economies, with BNB Chain’s throughput handling high-volume micropayments.

2025 Outlook: $1B AI Payment Market

The partnership could capture 5-10% of the $1 billion AI payment market, driving BNB Chain TVL to $20 billion. Risks include regulatory hurdles, but compliance features mitigate them.

In summary, Pieverse and Questflow’s x402b integration unlocks autonomous AI payments on BNB Chain, blending gasless efficiency with compliance for 2025’s agentic future.
