What is PayFi?
PayFi is a term introduced by Lily Liu, Chairman of the Solana Foundation. She describes PayFi as:
PayFi = A new financial primitive on-chain, built around sending/receiving settlement rather than transaction-based constructs, with transactions being a hallmark of DeFi.

Before diving into PayFi, let’s explore a few key concepts:
Time Value of Money
This is a fundamental concept in finance that refers to the difference in value of cash over time. Simply put, due to potential future earnings, today’s money is worth more than money in the future. For example, if you buy a Bitcoin with a 40% yield today by investing $1,000, you will earn $400 in a year. This illustrates the time value of money.
Payment Financing
This typically involves providing funds to businesses or individuals so they can make payments to suppliers or other parties in advance and then repay the funds at a later agreed time. For instance, a credit card is a classic payment financing tool that offers flexibility in asset allocation for both users and businesses.
Tokenization of Real-World Assets
PayFi leverages blockchain technology, stablecoins, and smart contracts to maximize the time value of money and create sustainably appreciating assets. It aims to bring real-world financial activities onto the blockchain, bridging the gap between traditional payment systems and decentralized finance. This way, PayFi can unlock trillions of dollars in payment volume, offer more efficient and inclusive financial services, and generate sustainable risk-adjusted returns.
This emerging field, known as Real World Assets (RWA), has the potential to revolutionize various sectors, from cross-border payments and trade financing to corporate expenditures and decentralized physical infrastructure. Ultimately, PayFi aims to provide blockchain-based solutions that surpass traditional payment alternatives.
Common Applications
Buy Now, Pay Later
Imagine dining at a restaurant with a bill of $10, but you prefer not to pay immediately. You can deposit $100 into a blockchain contract, and when the interest earned on this $100 reaches $10, this interest will be automatically paid to the restaurant, while your $100 is refunded to you. This allows you to use your funds to cover the bill without immediate cash outlay.
Addressing Accounts Receivable Issues
Accounts receivable refers to the amounts a company is owed after selling goods or providing services. This portion of funds represents a company’s assets, as it indicates that revenue will be received at some future point. Accounts receivable typically settle within a credit period and directly impacts the company’s cash flow. Proper management of accounts receivable is crucial for maintaining stable cash flow and operational continuity.
With PayFi, companies can utilize blockchain technology and smart contracts to accelerate payment processes, tokenize accounts receivable, and convert them into liquid digital assets. This allows businesses to receive funds faster and benefit from the time value of money, enhancing fund utilization efficiency and reducing the risk of cash flow delays. Additionally, PayFi’s decentralized system reduces counterparty risk and ensures transparency and trust in payment processes, further optimizing financial management.
Staking and Yield
By staking tokens such as ETH or USDC into various DeFi protocols, PayFi-related agreements can convert cryptocurrency yields directly into fiat currency for transactions.
Crypto Payment Cards
With integration with VisaCard, users can convert USDT and other cryptocurrencies into fiat for use in the real world. It also allows converting staked DeFi assets into stablecoins for spending and using staking and liquid yields for repayment. This vision aligns with KingCard’s future goals of expanding cryptocurrency payment possibilities and enabling users to earn while spending.
Conclusion
The impact of digital currencies and blockchain technology, though lacking a dramatic breakthrough moment like some other technological innovations, will be profound and lasting in transforming traditional financial systems. From the vision of a decentralized electronic cash payment system presented in the 2008 Bitcoin whitepaper to the recent technological advancements, this vision has gradually become a reality. Significant investments over the past decade have established blockchain infrastructure capable of supporting large-scale payments.
This transformation began in financial payments, from Bitcoin’s electronic cash to the rise of tokenized currencies and the innovative applications of PayFi, demonstrating the immense potential of blockchain technology in finance. Although the future development path is still uncertain, these advancements have already shown their deep impact on financial services. Digital currencies and blockchain technology may not appear as striking as other technologies, but they have the potential to fundamentally change trust and cooperation among people, leading to significant societal changes.
