Yesterday, GMPayer, a multi-chain payment hub built on the x402 protocol, completed the minting of its proof-of-concept token, BANG. Data shows that the 250,000,000 BANG tokens issued on GOAT Network were minted within just two hours of opening, generating over 50.5k transactions and accumulating 982 holders. Simultaneously, an equal amount of tokens issued on Metis Andromeda were minted within 7.5 hours, generating over 51.5k transactions and attracting 870 holders. Following this minting, BANG is now available on both GOAT Network's GoatSwap and Metis Andromeda's NetSwap trading pairs, providing initial liquidity for the token. The successful completion of this proof-of-concept activity marks substantial progress for the x402 protocol in building an autonomous machine economy. As a cross-chain, multi-currency payment hub powered by x402, GMPayer lays a solid foundation for realizing its envisioned universal AI value exchange layer. This achievement demonstrates the technological strength and synergistic efficiency of its core ecosystem comprised of LazAI, ZKM, Metis, and GOAT Network. Following the successful completion of its proof-of-concept phase, GMPayer is poised to move on to the next phase of development, continuing to explore the large-scale application of the x402 protocol in the AI Agent economy.
