The GMPayer payment hub based on the x402 protocol is launched, promoting AI Agents' autonomous cross-chain payments

LazAI, in collaboration with ZKM, officially launches the first multi-currency payment hub driven by x402 ------ GMPayer, in partnership with Metis and GOAT Network. This platform aims to build a decentralized multi-chain multi-currency payment system that supports instant, trustless interactions between AI Agents. GMPayer will evolve through a four-phase development path, starting from establishing a foundational payment hub and gradually advancing to a universal value exchange layer that supports seamless interaction across AI, data, and services.

GMPayer builds its technological ecosystem on four core strengths: LazAI directly binds data sources, rights, and benefits to datasets and models through the Data Anchoring Token (DAT) standard; ZKM employs zero-knowledge proofs to ensure the verifiability and trustlessness of x402 transactions; Metis provides low fees and fast finality as the execution and settlement core; and GOAT serves as the native Bitcoin settlement layer, achieving ultra-low-cost cross-chain liquidity through EIP-3009 and zkRollup.

The platform also launches the proof-of-concept token $BANG, issued simultaneously on Metis Andromeda and GOAT Network, with a total supply of 1 billion (split evenly between the two chains). Each chain will have 250 million for token minting and 250 million for liquidity, with token minting starting at 12:00 AM Singapore time on November 4, 2025. The $BANG token is currently only for proof-of-concept and has no utilities.

Participants can join in the following ways:

1. Visit the GMPayer official website to connect your wallet and select the 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 lasts for 72 hours and allows for repeated participation (with a single transaction limit of $1).
