The authenticity of x402 BNB is that it builds on BNB Chain, which makes good sense for trust and understanding. The only purpose of this launch is to improve the way of payments for AI Agents and users. Quack AI has released this news through its official X account.
x402 BNB Simplifies Crypto Transfers with Delegated Execution and Witness Signatures
X402 BNB uses two major standards of Ethereum, such as EIP-7702 Delegated Execution, in which users delegate actions like sending tokens or interacting with contracts to another system with authenticity and in a secure way. The second one is EIP-712 Witness Signatures, which checks the reality, structured, and human-readable signed data to safeguard users from signing malicious transactions.
X402 BNB is also taking an important step by replacing every manual approval transfer with one verifiable signature, which will reduce the extra efforts of users for the time of payment transfer. BNB Chain lacks a unified way to move it; therefore, most of the tokens still depend on outdated flows that provide hindrance and limit scalability.
One-Click, Gasless Payments for the Global Agent Economy
Quack AI is going to launch a system that definitely saves time and extra efforts for users and AI Agents in terms of payment transfer across the border. Simultaneously, x402 BNB fixes the problem of limited scalability by offering one-click, gasless transactions that are verifiable, auditable, and policy-aware. Basically, x402 BNB is setting the foundation for secured Governed AgentFi and accountable rails for the Agent Economy.
Moreover, in this process, users and AI Agents will be facilitated by One Signature experience, Modular Developer Stack, Secure by Design, Multi-Asset Ready, and Seamless Compatibility. All these features will contribute to the development and boost the level of users in Payment methods.

Upload private, explicit videos as a “nude-lending” cryptocurrency loan? “Hero Loan” targets people cornered with no way out—if they default, they upload OnlyFans.
A product that combines cryptocurrency, adult content, and a high-risk lending mechanism has recently sparked heated discussion in crypto circles and on social platforms. The project, named “Hero Loan,” promotes the slogan “unsecured loans,” but requires users to upload private videos as a condition, and ties default risk to an adult-platform monetization mechanism—prompting many netizens to describe it as “an encrypted version of loan-sharking/porn lending.”
The project even uses “If you think this won’t get used, it just means you haven’t reached rock bottom yet” as its promotional tagline, clearly targeting users with high risk and extreme capital pressure. However, shortly after it was exposed, one netizen said they had sent a video but didn’t receive any money; a KOL also responded that the project appears to have rug-pulled.
But honestly, a private video is only worth 60 bucks—that’s just too brutal.

According to information on the official website, the product runs on BNB Chain and is positioned for “people who have nowhere left to go—
