I’ve been following Quack AI and I must admit that what the team is doing with the Q402 layer is quite interesting for those tracking on-chain developments. Basically, they’ve solved a problem that no one was really addressing: the fact that making a simple transaction on the blockchain still requires multiple steps — authorize, transfer, then pay gas separately. It’s unnecessary friction, especially for companies and platforms dealing with real assets that need compliance and transparency.

Q402 is essentially an execution layer designed to turn all of this into a single seamless flow. The elegant idea is: the user signs once, the system handles the gas automatically, and the transaction follows predefined governance rules. They call it “signature as payment.” They’ve integrated with over 40 blockchains — BNB Chain, Polygon, Base, Linea — and have issued 7 million identities through the Governance Passport.

What makes this relevant is that Quack AI on-chain can do this in a verifiable and auditable way. Each transaction carries its own strategy, executes automatically, and is recorded on the blockchain. For RWA (tokenized assets), fund management, credit flows — any operation requiring traceability — it completely changes the game. They eliminate overlapping manual and complex processes.

Technically, they use Ethereum’s EIP-7702 and EIP-712. The first allows an execution coordinator to pay the gas and execute complex transactions with a single secure signature. The second ensures you’re signing well-defined intentions, not ambiguous requests. The combination enables trustless execution that’s policy-sensitive.

On the practical side: they’ve already validated this on BNB Chain. Developers benefit from lower development costs (using their SDK), compatibility with ERC-20, no default gas costs, and the “signature as payment” process reduces delays by over 70%. It’s especially useful for high-frequency agents and systems.

Regarding security: each transaction can be linked to a verified identity, and the system offers modules for KYC and jurisdiction filtering. It works in both open ecosystems and regulated environments.

In July 2025, they closed a $3.6 million funding round with Animoca Brands and Kenetic Capital. The funds are going toward multi-chain expansion of the execution coordinator, SDKs for wallets and dApps, and pilot RWA governance projects. The Q token acts as a participation and reward link — it’s not speculation, but activity-based on-chain engagement.

Their roadmap is ambitious: establish Q402 as the standard on BNB Chain and expand to more EVM networks, enhance agent capabilities with reasoning proofs, launch simulation environments to test strategies before real investment, and eventually create a unified economy of agents with protocol and chain coordination.

Their vision is clear: make Quack AI on-chain the invisible infrastructure for secure, automatic, cross-network execution. In a future where agents, applications, and institutions fully migrate to blockchain, they want Q402 to be that layer that turns intentions into actions seamlessly. Honestly, if they pull this off well, it could significantly change how complex operations function on-chain.
