Stablecoins Reshape Global Payments: A Deep Dive into the Four-Layer Technology Stack
Stablecoin Payments: Reshaping the Global Financial Transaction Landscape
The global financial system is undergoing profound changes. Traditional payment networks are facing comprehensive challenges from stablecoins due to outdated infrastructure, lengthy settlement periods, and high costs. Stablecoins are rapidly revolutionizing cross-border value flow models, business transaction paradigms, and the ways individuals access financial services.
In recent years, stablecoins have continued to develop and have become an important underlying infrastructure for global payments. Large financial technology companies, payment processors, and sovereign entities are gradually integrating stablecoins into consumer-facing applications and enterprise cash flows. At the same time, emerging financial tools such as payment gateways, deposit and withdrawal channels, and programmable yield products have greatly enhanced the convenience of using stablecoins.
This report provides a deep analysis of the stablecoin ecosystem from both technical and commercial perspectives. It studies the key participants shaping this field, the core infrastructure supporting stablecoin transactions, and the dynamic demand driving its applications. Additionally, it explores how stablecoins give rise to new financial application scenarios and the challenges they face in being widely integrated into the global economic process.
1. Why choose stablecoin payments?
To explore the influence of stablecoins, we first need to examine traditional payment solutions. These traditional systems include cash, checks, debit cards, credit cards, international wire transfers ( SWIFT ), Automated Clearing House ( ACH ), and peer-to-peer payments. Although they have become integrated into daily life, many payment channels, such as the infrastructure of ACH and SWIFT, have existed since the 1970s. While they were groundbreaking at the time, much of this global payment infrastructure is now outdated and highly fragmented. Overall, these payment methods are plagued by high fees, high friction, long processing times, inability to achieve 24/7 settlement, and complex backend processes. Additionally, they often require payments ( for unnecessary additional services such as bundled identity verification, lending, compliance, fraud protection, and bank integration.
Stablecoin payments are effectively addressing these pain points. Compared to traditional payment methods, using blockchain for payment settlement greatly simplifies the payment process, reduces intermediaries, and achieves real-time visibility of cash flow, which not only shortens settlement time but also lowers costs.
The main advantages of stablecoin payments can be summarized as follows:
2. The Landscape of the Stablecoin Payment Industry
The stablecoin payment industry can be divided into four technical stack layers:
) 1. First Layer: Application Layer
The application layer is mainly composed of various payment service providers ( PSP ), which integrate multiple independent deposit and withdrawal payment institutions into a unified aggregation platform. These platforms provide users with convenient access to stablecoins, offer tools for developers developing at the application layer, and provide credit card services for Web3 users.
a. Payment Gateway
A payment gateway is a service that securely processes payments and facilitates transactions between buyers and sellers.
Notable companies innovating in this field include:
The field of payment gateway providers can be clearly divided into two categories ### with some overlap (.
The developer-oriented payment gateway is designed to serve enterprises, fintech companies, and businesses that need to integrate stablecoin infrastructure into their workflows. They typically provide application programming interfaces )API), software development kits )SDK(, and developer tools for integration into existing payment systems, enabling features such as automated payments, stablecoin wallets, virtual accounts, and real-time settlement. Some emerging projects focused on providing such developer tools include:
Consumer-oriented payment gateways focus on the user, providing a simple and easy-to-use interface that facilitates stablecoin payments, remittances, and financial services. They typically include mobile wallets, multi-currency support, fiat currency deposit and withdrawal channels, and seamless cross-border transactions. Some well-known projects that focus on providing users with this simple payment experience include:
U Card
Cryptocurrency cards are payment cards that allow users to spend cryptocurrencies or stablecoins at traditional merchants. These cards are typically integrated with traditional credit card networks like Visa or Mastercard, enabling seamless transactions by automatically converting cryptocurrency assets to fiat currency at the point of sale.
The project includes:
There are many cryptocurrency card providers, and they mainly differ in terms of service areas and supported currencies, often offering low fees to end users to enhance their enthusiasm for using cryptocurrency cards.
) 2. Second Layer: Payment Processor
As a key layer of the stablecoin technology stack, payment processors are the backbone of payment channels, mainly covering two categories: 1. Deposit and withdrawal service providers 2. Stablecoin issuance service providers. They act as a crucial intermediary layer in the payment lifecycle, connecting Web3 payments to traditional financial systems.
a. Deposit and Withdrawal Processor
b. Stablecoin Issuance & Coordination Processors
( 3. Layer Three: Asset Issuer
Asset issuers are responsible for creating, maintaining, and redeeming stablecoins. Their business model typically relies on the balance sheet.
