The narrative around cryptocurrency is shifting. No longer confined to speculative trading or decentralized finance (DeFi) yield farming, the industry is gradually pivoting toward real-world utility and off-chain integration. At the heart of this evolution lies a growing emphasis on PayFi, Web3 payments, and the real-world asset (RWA) economy — a convergence that could redefine how value moves between blockchains and everyday life.
While Ethereum continues to dominate with its sprawling ecosystem, Solana has emerged as a leaner, more agile contender. After the collapse of FTX — a major blow given its early ties to the exchange — Solana rebounded through high performance, savvy marketing, and hardware innovation. The introduction of Firedancer, an upcoming validator client upgrade, promises enhanced network stability and throughput. Meanwhile, meme-driven campaigns and Web3-integrated mobile devices have reinvigorated user interest.
But beyond infrastructure and hype, Solana Foundation President Lily Liu’s concept of PayFi has sparked deeper conversations about the future of money in Web3. PayFi isn’t just another financial primitive — it represents a philosophical shift: from holding assets for speculation to using future yield for present consumption.
This transformation signals a broader industry trend: the de-commodification of crypto, where tokens are no longer treated solely as tradeable commodities but as instruments for real economic activity.
The Wallet Dilemma: Why Web3 Payments Have Fallen Short
To understand PayFi, we must first confront the limitations of today’s crypto wallets.
Between 2022 and 2023, Web3 wallets experienced a resurgence driven by account abstraction (AA), smart contract wallets, and rising traffic from decentralized exchanges. Wallets like OKX Wallet stood out by offering seamless cross-chain access and dApp interaction. Yet despite their popularity, most remain dependent on external platforms for monetization.

Why? Because current wallets lack a closed-loop payment system. Unlike PayPal or Alipay — which manage both user funds and merchant settlements — crypto wallets focus almost exclusively on transactional features: multi-chain support, gas optimization, and dApp discovery. They serve traders, not consumers.
Moreover, non-custodial design ensures security but sacrifices convenience. Users don’t “keep” money in these wallets the way they do in traditional apps; there's no automatic interest accrual, budgeting tools, or bill-splitting functions. As a result, while Web3 wallets control significant on-chain traffic, they fail to capture off-chain spending behavior.
Consider this real-world example: In September 2024, public figure "Chuan Bao" visited PubKey, a Bitcoin-friendly bar in New York, and purchased a $998 beer using Strike, a Lightning Network-based app. The bar accepted payment via Zaprite, another Lightning-compatible service.
Technically seamless? Yes. Economically efficient? Absolutely — merchants pay only minimal miner fees (averaging $1.46), compared to 1.95–2% charged by Visa or Mastercard. But structurally fragmented? Undeniably.
Here’s the catch: Chuan Bao used Strike; the merchant used Zaprite. Two different interfaces, united only by the underlying Bitcoin network. This is akin to paying with Alipay while the store receives via WeChat Pay — possible only because both rely on the same settlement layer.
In contrast, traditional payment systems thrive on interoperability and standardization. Card networks like Visa connect millions of merchants and billions of users through uniform protocols. Web3 lacks this cohesion. Despite thousands of dApps and dozens of chains, widespread merchant adoption remains limited — estimates suggest only around 30,000 global merchants accept Bitcoin, mostly online retailers like Travala.
Without unified standards, user-side adoption alone won’t suffice. True payment ecosystems require dual-sided support: users and merchants. That’s where PayFi begins to fill the gap.
What Is PayFi? Redefining Money Through Time Value
At its core, PayFi leverages the time value of money (TVM) — the idea that money available now is worth more than the same amount in the future due to its earning potential.
Lily Liu describes PayFi as a system where idle capital generates yield in DeFi, and that expected return can be used today. It transforms passive holdings into active financial instruments.
Imagine this scenario:
- Alice deposits 100 USDC into a DeFi protocol offering 5% APR.
- Bob runs a fruit stand and agrees to let Alice buy $5 worth of watermelon today in exchange for the future interest from her investment.
- One year later, Alice earns $5 in yield — which she transfers to Bob as agreed.
Alice gets immediate consumption value at no upfront cost; Bob gains a receivable backed by a predictable income stream.
Now scale this idea: Bob collects hundreds of such promises and wants to expand his business. He approaches a supplier demanding $5 million in upfront capital. Instead of cash, he offers tokenized claims to future yield — essentially creating tradable digital receivables.
These instruments can be assessed, bundled, and sold — much like commercial paper in traditional finance. If rated highly (say, AAA by an auditor), they attract investors seeking stable returns. Bob sells them at a premium, funds his growth, and investors earn passive income.
This mirrors real-world financial mechanisms — but built natively on-chain.
PayFi thus sits at the intersection of:
- DeFi (yield generation)
- Payments (off-ramping value)
- RWA (tokenizing real-world obligations)
Crucially, PayFi doesn’t require full asset tokenization (as with classic RWA models). It focuses instead on monetizing future cash flows, whether from staking rewards, lending yields, or even invoice payments.

PayFi vs. Payments vs. RWA: Mapping the Overlap
While often discussed separately, these three domains increasingly overlap:
- Web3 Payments focus on frictionless value transfer (e.g., Solana Pay, Binance Pay).
- RWA emphasizes bringing physical assets on-chain (e.g., tokenized bonds, real estate).
- PayFi enables spending against future yield, blurring lines between savings, credit, and spending.
Historically, projects like Ripple, Stellar, and Lightning Network laid early groundwork for cross-border settlements and fast micropayments. Then came the 2022 RWA wave — led by Ondo, Centrifuge, and Goldfinch — focusing on asset-backed lending.
Today’s PayFi innovators — including Huma and Arf — are building systems where DeFi yields fund real-world purchases. For instance:
- A freelancer earns USDC via global gigs.
- They deposit funds into a DeFi pool yielding 6% annually.
- A local coffee shop accepts “yield-backed” payments: customers spend against their projected returns.
- The shop receives stablecoins instantly; the customer repays from future earnings.
This creates a self-sustaining cycle: DeFi → Yield → Off-chain Spending → Merchant Adoption → More On-chain Activity.
Frequently Asked Questions
What is PayFi?
PayFi combines decentralized finance (DeFi), stablecoins, and payment systems to enable users to spend against their future yield — turning anticipated returns into present-day purchasing power.
How does PayFi differ from traditional payments?
Traditional payments move existing balances; PayFi allows spending based on expected income. It introduces credit-like functionality without centralized lenders.
Can PayFi work without stablecoins?
Stablecoins are essential for predictability. Volatile assets like ETH make future yield uncertain, undermining trust in repayment commitments.
Is PayFi just another form of borrowing?
Not exactly. While similar to credit, PayFi relies on verifiable on-chain positions rather than credit scores or collateral. It’s more transparent and programmable.
Which blockchains support PayFi best?
Solana leads due to low fees and high speed. Ethereum L2s like Arbitrum and Base also show promise as scaling improves.
Will PayFi replace traditional banking?
Unlikely in the short term. But it offers an alternative financial layer — especially for underbanked populations or cross-border transactions.

The Road Ahead: Building Real Economic Utility
The era of crypto as pure speculation is waning. The next phase belongs to ecosystems that bridge on-chain value with off-chain life.
PayFi doesn’t need mass adoption overnight. It starts with niche use cases — freelancers paying rent with staking rewards, farmers financing crops via tokenized receivables, students funding tuition with future yield.
As these micro-economies grow, they’ll attract merchants, developers, and regulators alike. The key will be designing systems that are secure, user-friendly, and interoperable across chains and borders.
Ultimately, PayFi isn’t just about new products — it’s about reimagining what money can do in a decentralized world.
History favors pioneers, not summarizers. And the path forward isn’t more trading — it’s deeper integration with reality.
