Just recently noticed Quack AI's new moves in the blockchain execution layer. Their launched Q402 execution layer indeed addresses a pain point that many people have been complaining about.

Currently, on-chain transactions still follow the old process: authorize first, then transfer, and finally pay Gas fees separately. This fragmented process not only hampers user experience but also becomes a nightmare for enterprises and RWA platforms because it requires complete audit trails and compliance verification. Quack AI's idea is straightforward: unify these scattered steps into a single process, where users only need to sign once, and the system automatically handles Gas, with each transaction following preset strategic rules. This is what they call the "sign-to-pay" model.

Q402 has already integrated with over 40 mainstream blockchains, including BNB Chain, Linea, Polygon, and Base. Through the "Governance Passport" system, more than 7.5 million on-chain identities have been issued. Based on the funding round in July 2025, the $3.6 million invested by Animoca Brands and other investors is mainly aimed at expanding Q402's multi-chain capabilities and developer tools, with a clear strategic focus.

Technically, Q402 relies on two Ethereum standards: EIP-7702 and EIP-712, to achieve secure execution. Simply put, EIP-7702 allows users to authorize an "execution coordinator" to proxy Gas payments and execute complex transactions, while EIP-712 ensures that users sign a clearly defined strategic intent rather than vague requests. This combination enables on-chain transactions to be trustless yet strategy-aware.

For developers, the benefits are quite tangible. Deployment on BNB Chain validated several key advantages: significantly reduced development costs (using their SDK for signing and Gas sponsorship), native support for standard ERC-20 tokens (no token upgrades needed), users don’t need to worry about Gas fees at all, transaction failure rates are extremely low, and governance settlement speeds have increased by over 70%. Especially for AI agents and high-frequency systems, this architecture is inherently designed for automation.

From a compliance perspective, each transaction can be linked to verified identities, with cryptographic techniques protecting privacy. It also supports optional KYC, regional restrictions, and strategic limitation modules. This means Quack AI’s on-chain solution can seamlessly integrate into open permissionless ecosystems while also adapting to regulated financial environments.

Their roadmap is quite ambitious. Recently, the focus is on strengthening Q402’s position on BNB Chain and expanding to more EVM networks; next, they will enhance AI agent reasoning and coordination capabilities; they also plan to introduce "pre-execution simulation" so projects can thoroughly test strategies before deploying real funds on-chain; finally, they aim to build a cross-protocol, cross-chain unified proxy economy.

In the long term, their goal is to make Q402 the default execution layer for on-chain systems. Imagine, regardless of the chain, asset, or application, all transactions, payments, and automation operations could be completed with a single smart signature, executed under strategic constraints. If this on-chain execution infrastructure truly becomes widespread, it would significantly boost the entire ecosystem’s efficiency. Currently, their focus on RWA and AI agents shows promising potential.
