Q402, Quack AI’s blockchain payment and settlement entity, has partnered with Stable, a blockchain for stablecoin payments. The partnership aims to unveil a gasless payment platform, removing one of the largest bottlenecks when it comes to scaling AI agents on-chain. As Quack AI disclosed in its official social media announcement, while AI agents are witnessing wider traction, the issue of gas balance management across diverse wallets has turned into a crucial operational issue. Hence, Q402 addresses it with the consolidation of gas management into an inclusive pool, streamlining agent execution.
Introducing Q402 × @Stable — A Partnership Built for the Age of AI Agents.
As onchain AI agents scale from dozens to thousands, gas management becomes a core bottleneck. More agents means more wallets, more gas balances, and more operational overhead.
Q402 solves this.

Q402 and Stable Integration Enables Predictable and Dollar-Denominated Gas Costs
The partnership takes into account the integration of Quack AI’s Q402 with Stable, making it the backbone for dollar-denominated and predictable costs. Additionally, the development also enables lightning-fast settlement, establishing an exclusive benchmark for AI-driven infrastructure. The innovation of Q402 lies in the project’s capability to efficiently sponsor transfers in $USDT0 from a single pool, alongside the maintenance of cost tracking per agent.
The development removes the requirement to disseminate funds across diverse wallets, enabling seamless operations for institutions and developers deploying wide-ranging AI systems. Leveraging Stable’s infrastructure permits Q402 to guarantee sub-second finality, a critical feature to boost AI-speed execution. Additionally, the native EIP-7702 support allows sign-to-pay transfers without any gas volatility exposure to agents, further minimizing complexity.
At the same time, the collaboration underscores the unique positioning of Stables as a renowned settlement layer dealing with $USDT. With dollar-denominated, predictable gas costs, it provides operators with efficiency and clarity when managing expenses. The respective merger of predictability, speed, and scalability turns Q402 into a crucial advancement, facilitating multi-agent deployments at a time when autonomous AI is seeing wider adoption.
Unlocking Gasless AI Agent Scaling and Transparent $USDT0 Costs
According to Quack AI, Stable’s integration offers 3 notable advantages to make it fundamental for the rollout of Q402. 1st of them is making $USDT0 the primary gas token to guarantee transparent costs. 2nd is sub-second finality to ensure AI agents’ operation at machine pace without any delays. Then, the 3rd is the EIP-7702 support for gasless and secure transfers to remove exposure substantially volatile markets. Overall, this partnership is set to establish a smooth environment for AI agent scaling across industries.
