ZEKTO Registers On-Chain Payment Patent Linking QR Codes and External Wallets

ZEKTO announced on the 16th that it has registered a patent for a 'Wallet-Based On-Chain Payment Method and System Using Visual Codes'. The patent number is No. 10-3015545.
This patent covers technology that processes payments using not only QR codes but also one-dimensional and two-dimensional visual codes recognizable by camera, such as barcodes and data matrices. It is designed to connect with external blockchain wallets without being limited to a specific QR standard or a separate dedicated payment interface.
The payment process works by generating a visual code containing the recipient's wallet address, payment amount, and order information on a merchant's POS, kiosk, or online payment screen. Users then scan the code with a supported external wallet such as MetaMask or Trust Wallet to proceed with payment.
The smart contract then verifies that the payment request matches the actual blockchain transaction before transferring assets. Electronic signatures are applied to payment requests to check for forgery and tampering, while random values and expiration periods prevent the same payment request from being reused. The system also verifies that the wallet receiving the payment is a pre-registered merchant.
Post-payment processing is also manageable. Each payment is assigned a unique identifier, and statuses such as payment completion, cancellation, refund, and dispute are recorded via smart contract. An NFT or digital on-chain receipt linked to the payment history is issued to connect payment records with post-processing details.
ZEKTO plans to apply this patent to its own stablecoin payment infrastructure, 'SSDA'. SSDA is a system designed to enable stablecoins such as USDT and USDC to be used for online and offline payments using visual codes such as QR codes and external wallets.
ZEKTO previously secured a patent for operation management technology that automates the issuance, collateral management, and liquidity adjustment of collateral-backed stablecoins. Through this new patent, the company has expanded its patent portfolio from stablecoin operation technology to the technology required for actual commercial payment processes.
Technical verification in a real payment environment is also underway. ZEKTO has signed a memorandum of understanding with BDACS, a digital asset infrastructure company, and LK Ventures, the operator of 'Life4Cuts', for the pilot introduction of a stablecoin payment system.
A payment proof-of-concept is scheduled to be conducted at Life4Cuts offline stores at Korea Blockchain Week (KBW) on October 1st. The KRW1 Korean won stablecoin issued by BDACS will be integrated as a payment method, and ZEKTO's SSDA will be used to verify payment requests, approvals, processing result confirmation, cancellations and refunds, and merchant settlement status.
Life4Cuts currently operates more than 1,000 stores in 30 countries worldwide, with over 3.8 million monthly users. Starting with this proof-of-concept, ZEKTO plans to expand the scope of application to offline commerce sectors such as tourism, content, and retail.
In addition to stablecoin payments, ZEKTO has previously proposed the KYA (Know Your Agent) framework in preparation for an environment where AI agents select products and make payments. KYA is a system for verifying the identity and payment authorization of AI agents. Overseas, the company is operating as a full member of the Vietnam Blockchain and Digital Assets Association (VBA), advancing related business cooperation.
