LazAI, in collaboration with ZKM, Metis, and GOAT Network, officially launched GMPayer, a multi-currency payment hub powered by x402. This platform aims to build a decentralized, trustless, multi-chain, multi-currency payment system supporting instant, multi-transaction payments between AI Agents. GMPayer will evolve through a four-stage development path, starting with establishing a basic payment hub and gradually becoming a universal value exchange layer supporting seamless interaction across the entire AI, data, and service chain. GMPayer's technological ecosystem is built upon four core strengths: LazAI directly binds data sources, rights, and benefits to datasets and models through the Data Anchored Token (DAT) standard; ZKM uses zero-knowledge proofs to ensure the verifiability and trustlessness of x402 transactions; Metis provides low fees and rapid finality as the execution and settlement core; and GOAT, as a native Bitcoin settlement layer, achieves ultra-low-cost cross-chain flow through EIP-3009 and zkRollup. The platform will simultaneously launch its proof-of-concept token, BANG. Token minting will begin at 00:00 China time on November 4, 2025, and will be issued simultaneously on Metis Andromeda and GOAT Network, with a total supply of 1 billion (half on each chain). Of these, 250 million will be allocated to token minting on each chain, and 250 million to liquidity. The BANG token is currently only for proof-of-concept use and has no utilities yet. Participants can join through the following methods: 1. Visit the GMPayer website (https://gmpayer.ai), connect your wallet, and select a network; 2. Convert $METIS or $GOATED to $xMETIS or $xGOATED at a 1:1 ratio; 3. Contribute $1 worth of tokens through the x402 payment interface to receive 5000 $BANG. This proof-of-concept token minting event will last for 72 hours and supports repeated participation (maximum of $1 per participation).
