LazAI Launches GMPayer: x402-Based Multi-Currency Payment Hub for AI Agents
Toronto, Canada, November 4th, 2025, Chainwire
LazAI, the leading AI application layer within the Metis ecosystem, today announced the launch of GMPayer, the world’s first multi-currency, multi-chain payment hub built on the x402 protocol designed specifically for AI agents. GMPayer enables seamless, instant settlements for data, compute, and services on a pay-per-request basis, ushering in a new era of autonomous agent-to-agent commerce.
GMPayer marks the first documented real-world deployment of the x402 protocol, enabling scalable and automated cross-chain transactions. Developed in collaboration with ZKM, Metis, and GOAT Network, GMPayer facilitates interactions between AI agents and blockchain infrastructure, enabling trust-minimized transactions without reliance on centralized intermediaries or conventional account systems.
“This launch marks a pivotal moment for AI in Web3,” said Ming Guo, Co-founder of LazAI. “For decades, the web has relied on external payment rails because HTTP had a roadblock due to a lack of a native payment protocol, so instead built workarounds to hide this pain point. x402 changes that by embedding payments at the protocol layer. GMPayer operationalizes it for AI agents, turning every API call into a verifiable, settled transaction. We’re not just building payments – we’re rebuilding the web for an agentic future.”
Addressing the AI Payment Challenge
Metis is unifying its ecosystem through a landmark governance vote that created the Ecosystem Alignment and Growth Reserve (EAGR) to fuel cross-project synergy, designating METIS as the native gas token for LazAI Network and empowering initiatives like GMPayer—a collaborative breakthrough with LazAI, GOAT Network, and ZKM. This x402-powered payment hub dismantles legacy bottlenecks: ad-funded, human-centric models fail at AI agents’ machine-speed consumption, while external rails impose latency, custody risks, and silos stifling autonomy. GMPayer delivers instant, trustless, multi-chain settlements, with phased rollout over four weeks (full details: https://forum.ceg.vote/t/governance-proposal-metis-ecosystem-unification-and-economic-model-evolution/11006/2).
What is GMPayer
GMPayer (GOAT–Metis–Payer) is an x402-powered hub that facilitates instant, trustless payments across multiple blockchains and currencies. Its core purpose: enable agent-to-agent and agent-to-service payments across EVM chains and the Bitcoin ecosystem.
Key features in Phase 1 include:
- x402 Gateway: Manages 402 challenges, payment intents, and response streaming.
- Multi-Chain Router: Optimizes venue selection based on latency, fees, and liquidity; EVM-first, with extensibility.
- Currency Adapters: Supports multi-stablecoins (beyond USDC), with real-time quotes and slippage controls.
- Agent Wallet Abstraction: Enables non-custodial approvals, rate limits, budgets, and revocations.
- Policy & Risk Engine: Includes guardrails, anomaly detection, and circuit breakers.
- Observability Tools: On-chain receipts and SLA telemetry for refunds and audits.
- SDKs: Lightweight libraries for agent frameworks and provider integrations.
A Collaborative Foundation for Agentic Commerce
GMPayer’s open architecture invites builders and providers to participate:
- LazAI: Through its Data Anchoring Token (DAT) standard, LazAI binds provenance, rights, and revenue directly to datasets and models. Each x402 transaction is mapped to its contributors, enabling automatic per-call revenue routing across multiple chains.
- ZKM: With zero-knowledge proofs, ZKM ensures x402 facilitators remain verifiable and trustless. It validates quotes, authorizations, and payment payloads – providing portable truth for agents and auditors while preserving neutrality.
- Metis: Serving as the execution and settlement backbone, Metis anchors transactions on Andromeda and scales inference workloads via Hyperion. Its low fees and fast finality make x402 microtransactions economically viable.
- GOAT: As a native Bitcoin settlement layer, GOAT introduces EIP-3009 support and zkRollup infrastructure, bridging stablecoins and Bitcoin with ultra-low-fee cross-chain operations between GOAT and Metis.
Why GMPayer Matters: From Promise to Protocol Reality
In a web environment increasingly shaped by autonomous agents, traditional advertising models may become less effective, prompting a shift toward “per request” settlement mechanisms designed to align stakeholder incentives and facilitate transparent value exchange. This shift is envisioned as part of a broader transformation, outlined in a four-phase framework:
- Hub Buildout: Multi-currency x402 for independent agent payments.
- Trust & Control: User-defined policies and budgets for micro-spends.
- AI Business Network: DAT as the core asset for the data layer, monetizing every call.
- Universal Exchange: Enabling any Web3 chain to integrate AI via x402.
How it works: https://gmpayer.ai/
Users can send $xMETIS or $xGOATED via an x402 payment request on Metis Andromeda or GOAT Network. Each transaction generates a verifiable proof and returns a corresponding amount of $BANG tokens as confirmation. GMPayer supports both the Metis Andromeda and GOATGoat Network, and allows you to convert tokens between $METIS/$xMETIS and $GOATED/$xGOATED at a 1:1 ratio. Note: $xMETIS and $xGOATED are EIP-3009 compatible tokens designed to support the x402 protocol standard.
