Quack AI and Mantle have officially announced that their Q402 payment infrastructure will be integrated into the Mantle ecosystem. This initiative aims to build a gas-free stablecoin payment channel to enhance the speed and convenience of stablecoin payments, making it more suitable for institutional use. Through Q402, users can easily transfer USDC/USDT with just one signature to complete the transaction, without needing to hold MNT for gas fees. Quack AI announced this news via its official social media platform.
Mantle and Quack AI are jointly reshaping the stablecoin infrastructure to achieve gas-free settlements. This collaboration eliminates the impact of gas fees on MNT balances, allowing users to complete each transaction without needing to migrate wallets or top up gas. Additionally, the alliance provides instant signature payment functionality for existing wallets (such as MetaMask or OKX Wallet), while traditional wallet addresses remain usable, simplifying the payment execution experience.
The common goal of both parties is to improve the stablecoin payment infrastructure through gas-free settlements. To this end, Mantle offers sub-second block times, alignment with Ethereum's security, and higher throughput. Mantle was created to lay the foundation for stablecoin infrastructure, real-world assets (RWAs), institutional liquidity, and settlement systems compatible with traditional finance (TradFi).
With advanced blockchain technology support, they also ensure the security of payments to meet users' high regard for asset safety. Meanwhile, their collaborative initiative ensures compliance, addresses trust issues for stablecoin issuers, and relies on backend sponsors for the gas-free user experience, while promotion depends on merchant support.
