BlockBeats news, on November 3rd, LazAI jointly developed with ZKM, in collaboration with Metis and GOAT Network, officially launched the first multi-currency payment hub driven by x402 - GMPayer. The platform aims to achieve instant, trustless multi-chain multi-currency settlement, promoting on-chain value interoperability of AI, data, and services. GMPayer will evolve through a four-phase path, gradually developing from a basic payment hub to a universal value exchange layer. Its core technologies include LazAI's Data Anchoring Token (DAT) standard, ZKM's zk-SNARKs verification mechanism, Metis's low-cost settlement layer, and GOAT Network's native Bitcoin cross-chain liquidity support. The platform simultaneously launched the proof-of-concept token $BANG, issued on both Metis Andromeda and GOAT Network with a total supply of 1 billion, currently only for proof of concept with no practical function. Users can participate in a limited-time 72-hour token minting event through the GMPayer official website, contributing 1 dollar to receive 5000 BANG. The launch of GMPayer marks the first implementation of the x402 protocol in the AI economy, promoting AI Agents towards autonomous trading and decentralized machine economy.
