Today, let's talk about a newly launched project—GMPayer. An experimental project that might reshape the way value is exchanged between AI agents. While going through the materials, I felt that it cleverly integrates multiple cutting-edge modules, and I'd like to share my observations with you. The HTTP status code 402 has been a placeholder for "payment required" for the past 30 years. However, it wasn't until AI agents gradually became independent economic participants that this issue truly emerged: machines now have funds, servers require payment, but the protocol itself lacks a native way to complete the exchange. In September 2025, Coinbase and Cloudflare initiated the x402 Foundation, with major companies like Google, Visa, AWS, and Anthropic joining in. The goal was to solve this bottleneck in a decentralized manner. However, having a standard is not enough. To make AI-to-AI payments both secure and reliable, value, proof, rights, and throughput must be bound together at once—this requires a fast lane, a truth layer, an ownership layer, and a mechanism that supports multi-currency flow, and must be cross-chain scalable without relying on centralized intermediaries. This is when GMPayer enters the scene. It officially launched on November 3rd, with the full name GOAT-Metis-Payer, and is the first multi-currency payment hub driven by x402. It was developed by LazAI and ZKM, and is jointly supported by Metis and GOAT Network @GOATRollup. Simply put, it allows AI agents to make instant, trustless pay-per-request payments across multiple blockchains and currencies, completely eliminating intermediaries, accounts, or human intervention. This means that the x402 protocol can now truly operate in a multi-chain environment. Technically, GMPayer integrates four key components: LazAI binds data sources, rights, and revenue directly to datasets and models through its data anchoring token standard, ensuring that each x402 transaction automatically distributes revenue according to the calls made; ZKM ensures the reliability and verifiability of the entire process using zero-knowledge proof technology, keeping the payment load neutral and transparent; Metis serves as the execution and settlement core, anchoring transactions on Andromeda and expanding inference workloads through Hyperion, with low fees and fast finality making microtransactions feasible; GOAT acts as the native Bitcoin settlement layer, introducing EIP-3009 support and zkRollup infrastructure to achieve ultra-low cost cross-chain operations. This combination is not just a random assembly, but a carefully designed solution tailored to the needs of the AI economy. GMPayer has outlined four clear stages: Stage one is to build a payment hub, allowing AI agents to independently pay for data and computational resource costs, creating real economic interactions between agents; Stage two focuses on making payments more trustworthy and controllable, allowing users to securely grant small payment permissions to agents while maintaining budget limits; Stage three will build an AI business network using DAT as the asset unit, making AI services themselves tradable assets; Stage four aims at a general AI value exchange layer, enabling any Web3 chain to seamlessly integrate AI into the application layer. This path starts from specific payment scenarios and gradually expands into a decentralized AI economic ecosystem, which is logically solid. Currently, the project team has also launched a concept verification token, $BANG, allowing people to experience the system firsthand. $BANG is issued simultaneously on Metis Andromeda and GOAT Network, with a total supply of 1 billion tokens, 500 million on each chain. Of these, 250 million are allocated for token minting and 250 million for liquidity. The participation process is simple: by contributing $1 USD via the x402 standard on either $xMETIS or $xGOATED, you can receive 5,000 $BANG tokens. The minting starts at 00:00 Beijing Time on November 4th and lasts for 72 hours, with a maximum contribution of $1 per transaction, but you can participate multiple times. The process is also user-friendly: first, you select the network—Metis Andromeda or GOAT Network—and connect your wallet. If your balance is insufficient, you can use the built-in conversion function to swap $METIS to $xMETIS or $GOATED to $xGOATED without slippage, at a 1:1 ratio. Then, click "Mint now" on the minting interface, and the system will automatically deduct $1 worth of tokens and immediately return 5,000 $BANG tokens to your wallet. The entire process is based on the EIP-3009 standard, ensuring compatibility with the x402 protocol. Here is the detailed user guide: https://t.co/PEEvUjBd2S From an investment perspective, GMPayer's potential lies in its entry into a rapidly growing sector. The AI agent economy requires a reliable payment infrastructure, and x402 is becoming an industry standard. Combined with the ecosystem support from Metis and #GOAT, the technical integration and timing are well-considered. Although $BANG is currently only a concept verification token with no practical use, its design demonstrates how multi-chain payments can be combined with AI needs. If the subsequent stages proceed smoothly, it may drive the value flow of the entire ecosystem. Personally, I think this project is not just a technical demonstration, but is actually building a framework that allows machines to autonomously exchange value. In the long term, it may become a key infrastructure for the integration of #Web3 and #AI. Clearly, the launch of #GMPayer is a noteworthy milestone. It's not just another payment tool, but a concrete step toward a decentralized AI economy. If you're interested in AI agents or cross-chain payments, you might want to check out the detailed guide on the official website and experience the minting process yourself—after all, firsthand participation allows for a more intuitive understanding of how it works. In the future, as more AI services are integrated, this hub may become a core node for value exchange. We can keep an eye on its evolution. #GOATNetwork #GOAT2026 #LFGOAT #GOATRoll @StoryProtocol @StoryChina_
