What is PayFi? The Next Direction of Crypto Payments
PayFi is a concept that began spreading rapidly within the cryptocurrency industry in 2025. Its full name is Payment Finance. The core idea is to combine payments with financial returns, allowing your funds to generate yield while you make a payment, rather than the funds being merely transferred statically as in traditional payments.
The concept was first proposed by Solana Foundation President Lily Liu in 2024. By 2026, multiple projects are already building real products around this direction.

1. What Problem Does PayFi Solve?
Traditional payments have a hidden cost: the loss of time value.
When you pay with Alipay or a bank card, the money leaves your account and arrives at the merchant's account. During this transfer, the funds are in transit and generate no returns.
The PayFi vision is: If payment settlement can be completed in real-time on-chain, and before settlement is finalized, the funds are still running in some yield protocol, then the time value of the payment is not wasted.
A further vision: You don't need to deposit money into a payment account in advance. Instead, you keep your funds in a DeFi protocol generating continuous interest. When you pay, the fee is deducted from the yield, while the principal always generates returns.
2. What is the Difference Between PayFi and DeFi?
DeFi (Decentralized Finance) core scenarios are lending, trading, and providing liquidity. Users are asset managers aiming to "make money work for them."
PayFi's core scenario is payments. Users are payers who "spend money," but they also make their money work for them while spending.
The two are not substitutes. PayFi can be understood as an extension of DeFi applied to the payment scenario.
3. Main Directions for PayFi in 2026
Direction 1: Stablecoin Cross-Border Payments
Traditional cross-border remittances use the SWIFT system, which has high fees and slow settlement. Stablecoin cross-border payments can be completed within minutes with extremely low fees. PayFi adds a yield layer in this direction: while funds wait for final settlement, they still generate returns in on-chain protocols.
Direction 2: Buy Now Pay Later on Chain
An on-chain version of buy now, pay later. Users use future earnings (e.g., staking rewards, DeFi interest) to pay for current consumption. The principal always generates returns on-chain, eliminating the need to prepare cash in advance.
Direction 3: Salary Streaming
Real-time salary disbursed by the second or day, instead of traditional monthly settlements. Employees can withdraw earned wages at any time without waiting until the end of the month. Funds generate continuous interest in the protocol until withdrawn.
4. Practical Significance for Ordinary Users
Currently, PayFi is still in its early stages. Most products have limited usability for average users. However, a few practical scenarios are already accessible:
- Using stablecoins for cross-border transfers, which are faster and cheaper than traditional remittances.
- Depositing stablecoins into protocols supporting the PayFi concept to earn yields while waiting to spend.
The direct impact of PayFi on users in mainland China is currently limited. However, if stablecoin payments become globally widespread, it will substantially change fund entry/exit methods and cross-border transfers.
5. Frequently Asked Questions
Q: Is PayFi safe? The security of a PayFi project depends on the specific protocol's smart contract quality. Like DeFi, it faces risks such as contract vulnerabilities and liquidity issues. Early-stage projects carry higher risks. Before participating, you need to understand the audit status of the specific product.
Q: What is the relationship between PayFi and CBDC? PayFi is based on public blockchains and stablecoins, forming a decentralized payment finance system. CBDC is a digital currency issued by central banks, which is centralized. Their directions differ, and they are competitive.
Q: Are there more PayFi projects on Solana than on Ethereum? Currently, yes. The PayFi concept is primarily promoted by the Solana Foundation. Solana's low gas fees and high speed are more suitable for payment scenarios, so related projects are mainly within the Solana ecosystem.
