The post Quack AI Unveils Production-Ready Q402 on Avalanche C-Chain to Scale Agent Workflows appeared on BitcoinEthereumNews.com.

Quack AI announced today that its signature-based execution layer, Q402, is now live on the Avalanche C-Chain, a move the startup says will make agent-driven applications feel native on one of the fastest L1 ecosystems. In a post on X, the team framed the deployment as a milestone for “verifiable, policy-aware execution” that leverages Avalanche’s sub-second finality and builder-first tooling to scale real-world agent usage. Quack AI says the release brings three headline features to the Avalanche developer community: a “Zero Gas Barrier” that allows ERC-20 settlements without requiring users to hold AVAX for gas, a “Sign-to-Pay” flow that decouples user intent from transaction execution, and a production-ready, auditable execution fabric for what the company calls the emerging agent economy. From Sign to Settlement At its core, Q402 uses signature-based authorization: a single cryptographic signature represents a user’s intent and can be carried through to execution by relayers and facilitators. That model collapses the traditional three-step UX, sign, fund gas, submit, into a unified “sign-then-settle” experience that Quack AI argues is far better suited to automated agents and large-scale, real-world flows. The Quack AI documentation expands on Q402 as an implementation of an open x402 standard that pairs delegated execution with governance intelligence and policy enforcement, signaling the project aims to be more than a UX band-aid and instead a foundational layer for autonomous on-chain systems. For Avalanche builders, the most immediate benefit will likely be reduced onboarding friction. Removing the need for end users to hold native gas tokens simplifies payments, micro-transactions, and other UX-sensitive flows common in consumer apps, games, and tokenized financial services. Sign-to-Pay additionally allows service providers to separate the approval step from the mechanics of settlement, opening possibilities for safer delegated workflows where institutions or multisig setups can sign intent and trusted infrastructure handles the…
