I just noticed a pretty interesting phenomenon. The blockchain transaction process still sticks to the old way: authorization, transfer, and then paying Gas fees separately. This step-by-step approach not only hampers user experience but is also a nightmare for RWA platforms and institutions that require compliance and transparency. Quack AI's recently launched Q402 execution layer is aimed directly at this pain point.

Simply put, what Q402 wants to do is unify these fragmented steps into a single process. Users only need to sign once, the system automatically handles Gas fees, and transaction rules are executed automatically. This "sign-to-pay" logic sounds simple, but behind it are Ethereum standards EIP-7702 and EIP-712 to ensure security—one handles authorization for executing the coordinator to pay Gas, and the other ensures users sign clear intent and policy rules, not vague requests.

I think this is a pretty big change for developers. No need to build your own signature, Gas sponsorship, and execution infrastructure; just use the SDK. It’s compatible with standard ERC-20 tokens, users have zero Gas perception, and transaction failure rates are extremely low. Quack AI's on-chain implementation has already been tested on BNB Chain, with governance settlement speeds increased by over 70%, which is quite convincing data.

From an ecosystem perspective, Quack AI has already issued over 7.5 million governance identities, connected to more than 40 networks, and on-chain revenue has verified over $3.5 million. The funding round last July (led by Animoca Brands and Kenetic Capital with $3.6 million) mainly focused on multi-chain expansion, SDK development, AI strategy explanation, and RWA governance pilot projects.

Interestingly, they also built-in a "governance passport" system, where each transaction can verify identity and protect privacy through cryptography. For scenarios requiring KYC, regional restrictions, or policy constraints, Q402 also offers optional compliance modules. So this system can adapt to both permissionless open ecosystems and regulated financial environments.

In the long term, Quack AI on-chain aims to make Q402 the default execution layer. No matter which chain it’s on, what assets are used, or what applications run, all transactions, payments, and automation can be completed with a single smart signature, with policy constraints built in. Future features will include pre-execution simulation, smart fund management, multi-agent coordination, and cross-chain unified execution records. This approach is definitely worth paying attention to.
