PayFi: A New Financial Paradigm Merging Web3 Payments and Decentralized Finance

Today, as the cryptocurrency market reaches a scale of $2 trillion, the traditional financial market, with a size of $400-600 trillion, undoubtedly represents a vast blue ocean. Although we have seen the rise of paths such as asset tokenization, the early-stage physical asset on-chain model still faces issues such as insufficient liquidity. Even with the resurgence of the Internet of Things driven by DePIN, it is still difficult to address the core issues.

In this context, the importance of Web3 payments is becoming increasingly prominent. It not only promotes the widespread adoption of stablecoins, especially in non-trading scenarios, but also serves as the core of the entire ecosystem. Data shows that the total supply of stablecoins is approximately $170 billion, with the asset value settled annually reaching trillions of dollars. Approximately 20 million addresses engage in stablecoin transactions each month, with over 120 million addresses holding a non-zero stablecoin balance.

Web3 payments bring advantages such as instant settlement, 24/7 availability, and low-cost transactions to traditional financial payment networks. However, this is just the beginning. What is even more noteworthy is the new financial market created by the innovative applications of PayFi. As an emerging field that integrates Web3 payments, tokenization of physical assets, and Decentralized Finance, PayFi is expected to become a key driver of industry development.

The Essence and Value of PayFi

PayFi, short for Payment Finance, is an innovative model that combines payment functions with financial services based on blockchain and smart contract technology. It uses blockchain as the settlement layer, integrating the advantages of Web3 payments and Decentralized Finance, aiming to achieve efficient and free value circulation.

PayFi's goal is to realize the vision depicted in the Bitcoin white paper: to establish a peer-to-peer electronic cash payment network that does not require a trusted intermediary. At the same time, it fully leverages the advantages of Decentralized Finance, creating a brand new financial market, providing innovative financial experiences, developing complex financial products and application scenarios, and ultimately forming a complete value chain.

In this emerging PayFi financial market, not only can the efficiency of Web3 payments be improved compared to traditional finance, such as instant settlement, reduced costs, increased transparency, and global accessibility, but it can also achieve global network decentralization, permissionless access, asset autonomy, and personal sovereignty based on Decentralized Finance.

PayFi is not simply equivalent to Web3 payments, Decentralized Finance, or the tokenization of physical assets. It is an innovative application that integrates these concepts, covering payment, trading, as well as lending, wealth management, and investment activities of digital assets. Through blockchain and smart contract technology, PayFi not only makes global financial payment activities more convenient and economical but also significantly reduces the friction and costs in traditional financial payment services.

The Significance of PayFi

The true meaning of PayFi lies in promoting the practical application of digital assets in the real world. On the positive side, it can align with the trend of Web2 users migrating to Web3, providing traditional financial payment companies with opportunities to leverage blockchain technology to expand their market share. On the negative side, the Web3 community can use payment as a medium to leverage blockchain technology to address the pain points of the traditional financial system, achieving new financial models and product experiences that are difficult for traditional finance to accomplish.

Currently, Web3 payments are still in the early stages, mainly using digital currencies as a payment medium, such as in scenarios like cross-border remittances, over-the-counter trading, and payment cards. This semi-centralized approach makes it difficult to fully leverage the advantages of the on-chain Decentralized Finance ecosystem, and the application scenarios are relatively limited.

With the development of PayFi, the value transfer methods based on blockchain and smart contracts will accelerate the integration of Web3 payments and Decentralized Finance services, improving the practicality and efficiency of digital assets in everyday transactions and complex financial environments. The emergence of PayFi is expected to break the long-standing separation between traditional finance and crypto finance, becoming a key factor in promoting the large-scale adoption of cryptocurrencies.

Advantages of Solana's PayFi

Solana has significant advantages in the PayFi sector, mainly reflected in three aspects: high-performance public chain, capital liquidity, and talent mobility. These advantages create barriers that are difficult for other competitors to cross in the short term.

From the perspective of PayFi infrastructure, Solana performs exceptionally well on multiple levels:

1. Blockchain Settlement Layer: Solana's high throughput, low cost, and fast settlement capabilities, along with the performance improvements brought by the Firedancer upgrade, provide a solid foundation for the rapid implementation of PayFi projects.

2. Currency Layer: The cooperation between Solana and institutions such as Ondo Finance, Visa, Circle, Stripe, along with the launch of PYUSD, has greatly enhanced its stablecoin ecosystem. Currently, the total amount of stablecoins on Solana has reached 3.6 billion USD, mainly including USDC, USDT, PYUSD, and USDY.

3. Asset Custody Layer: The security of smart contracts in the Solana ecosystem, private key management, and compatibility with traditional finance and Decentralized Finance provide strong support for on-chain asset custody.

4. Compliance Layer: Projects within the Solana ecosystem generally focus on compliance, ensuring that transactions and the flow of funds meet KYC/AML/CTF requirements and adapt to the laws and regulations of different jurisdictions.

5. Application Layer: Solana has built a rich application scenario on the consumer side, forming a strong ecosystem. Payment scenarios cover online shopping, social e-commerce, offline activities, and gaming, among other fields. Payment mediums include PayPal PYUSD, MakerDAO stablecoin, SOL debit card, etc. Payment gateways such as Shopify Blinks and Helio Pay/Solana Pay provide users with convenient payment options.

In addition, Solana is actively laying out its enterprise market, providing liquidity support for cross-border trade and supply chain finance through the tokenization of physical assets. Compared to Ethereum's "asset chain" positioning, Solana is consolidating its status as a "payment chain," becoming the preferred blockchain solution for consumer retail and payment-related products.

Conclusion

In the long run, the Web3 industry is shifting towards offline and real consumption scenarios. PayFi provides a way to realize the slogans of "making DeFi great again" and "promoting the mass adoption of cryptocurrencies."

PayFi not only improves the efficiency of traditional payments and reduces costs, but more importantly, it creates a whole new financial market. In this market, traditional finance and crypto finance are deeply integrated, accelerating the integration of payment and financial services through the development of stablecoins.

In the future financial ecosystem, PayFi will become a key driving force, providing users with more freedom, efficiency, and innovative financial services.
