In a significant development for cryptocurrency adoption, South Korean fintech firm Danal has secured a pivotal patent for a novel payment and settlement system, announced on March 21, 2025. This technology, designed to bridge the gap between volatile digital assets and real-world commerce, could fundamentally reshape how businesses accept crypto payments. The patent specifically covers a method for linking various digital assets through a sophisticated corporate wallet infrastructure.
Crypto Payment Patent Solves a Core Merchant Problem
Danal’s newly patented technology directly addresses one of the most significant barriers to mainstream crypto adoption: price volatility. Merchants have historically been reluctant to accept digital currencies like Bitcoin or Ethereum for everyday transactions because the value of a payment could plummet before conversion to fiat currency. Consequently, Danal’s system introduces a crucial intermediary layer. It enables customers to pay with their chosen digital asset, while merchants receive a stable settlement in their local currency or a stablecoin through their existing payment terminals.
This process effectively insulates businesses from the wild price swings characteristic of the crypto market. The system reportedly operates in real-time, ensuring swift transaction finality. Furthermore, the technology leverages a corporate wallet architecture, which acts as a secure hub for managing the conversion and settlement process. This architecture is distinct from individual user wallets and is built for high-volume, compliant business operations.
The Mechanics Behind Danal’s Settlement Technology
At its core, the patented system functions as a real-time conversion and routing engine. When a customer initiates a payment, the system instantly calculates the equivalent fiat value based on a secure, aggregated price feed. It then executes the conversion, either internally or through a partnered liquidity provider, before settling the stable funds into the merchant’s account. The corporate wallet manages the entire lifecycle, including security, reconciliation, and reporting.
Key technical components likely include:
- Multi-Asset Support: The ability to accept a wide range of cryptocurrencies and tokens.
- Real-Time Oracle Integration: Secure price feeds to ensure accurate and fair conversion rates.
- Legacy System API: Connectors that allow the technology to interface with standard point-of-sale (POS) and payment gateways already used by merchants.
- Regulatory Compliance Layers: Built-in features for transaction monitoring (AML) and record-keeping to meet financial regulations.
Expert Analysis: A Step Toward Pragmatic Adoption
Financial technology analysts view this patent as a move toward pragmatic, rather than ideological, cryptocurrency adoption. “Innovations like Danal’s patent are essential for the ‘plumbing’ of the crypto economy,” notes Dr. Alisha Chen, a fintech researcher at the Digital Finance Institute. “They don’t just promote using crypto for its own sake; they solve a tangible business problem. By removing volatility risk for the merchant, the technology lowers the adoption hurdle significantly. This is a classic example of blockchain technology being applied as a utility to improve existing financial processes.”
The patent also arrives amid a broader industry trend. Major payment processors and financial institutions have been actively exploring and filing patents for similar settlement and bridge technologies throughout 2024 and early 2025. Danal’s grant, specifically for its corporate wallet linkage method, carves out a distinct position in this competitive landscape. It builds upon the existing infrastructure of Paycoin (PCI), Danal’s proprietary payment-focused cryptocurrency, potentially increasing its utility and integration scope.
Context and Impact on the Payments Landscape
Danal, established in 1997, is not a newcomer to payments. Initially a mobile billing specialist, the company pivoted to blockchain with the launch of the Paycoin project. This background in traditional electronic payments provides crucial experience (E-E-A-T) in handling high-volume, secure transactions—expertise directly applicable to this new patent. The grant could accelerate Paycoin’s ecosystem growth by making PCI a preferred asset within its own settlement network.
The potential market impact is substantial. Sectors with high transaction volumes and international clientele, such as e-commerce, travel, and digital services, stand to benefit immediately. A small online retailer, for instance, could now accept payments from global customers without worrying about currency conversion fees or crypto volatility, potentially increasing sales and simplifying accounting.
Comparison of Traditional vs. Patented Crypto Payment Flow:
| 1. Customer Payment | Customer sends crypto from personal wallet to merchant’s wallet. | Customer authorizes payment; asset is sent to Danal’s corporate wallet. |
| 2. Merchant Receipt | Merchant receives volatile cryptocurrency directly. | System instantly converts crypto to stable value at point of sale. |
| 3. Settlement | Merchant must manually exchange crypto, incurring fees and delay. | Stable funds (fiat or stablecoin) are settled to merchant’s existing bank/POS system. |
| 4. Risk | High price volatility risk borne entirely by the merchant. | Volatility risk is managed by the system’s real-time conversion. |
Conclusion
Danal’s newly secured patent for crypto payment and settlement technology represents a concrete advancement in making digital assets practical for everyday commerce. By solving the critical issue of price volatility for merchants through its intelligent corporate wallet system, the technology lowers a major adoption barrier. This development underscores a maturation phase in the cryptocurrency industry, where innovation focuses on seamless integration with the existing financial world rather than merely disrupting it. The success of this crypto payment patent will ultimately depend on its commercial implementation, regulatory acceptance, and adoption by merchants seeking a safer bridge to the digital economy.
FAQs
Q1: What problem does Danal’s crypto payment patent solve?
It solves the problem of cryptocurrency price volatility for merchants. The technology allows customers to pay with digital assets while guaranteeing the merchant receives a stable, predictable settlement, shielding their revenue from market swings.
Q2: How does the technology protect merchants from volatility?
The system uses a real-time conversion mechanism. At the moment of transaction, it calculates the fiat value of the crypto payment and immediately converts it, settling stable funds (like local currency or a stablecoin) into the merchant’s account through their normal payment systems.
Q3: What is a “corporate wallet” in this context?
Unlike a personal crypto wallet, a corporate wallet is an institutional-grade digital asset management system designed for businesses. It handles security, high-volume transactions, compliance, and the automated conversion processes central to Danal’s patented technology.
Q4: Does this mean merchants need new hardware to accept these payments?
Not necessarily. A key aspect of the patent is integration with existing merchant systems. The technology is designed to connect via APIs to standard point-of-sale (POS) software and payment gateways, potentially requiring only a software update rather than new hardware.
Q5: How does this patent relate to Paycoin (PCI)?
Danal is the operator of the Paycoin (PCI) project. This patent likely enhances the utility and infrastructure of the Paycoin ecosystem, potentially making PCI a seamlessly integrated asset within this new payment and settlement network.
