How Crypto Neobanks Work: Frax, Cards, and Visa’s Role

Sam Kazemian of Frax unpacks the sudden explosion of crypto neobanks, explaining how they serve as the crucial bridge between on-chain finance and the real world. He reveals Frax’s strategy to become the foundational infrastructure for this new wave, ultimately aiming to create a self-sufficient, on-chain economy.

The Rise of the Crypto Neobank

  • Crypto neobanks are essentially sleek, user-friendly wrappers built on top of traditional banking rails, designed to blur the lines between crypto and fiat. They solve the clunky on-ramping problem, moving beyond centralized exchanges to create a smooth, integrated financial experience where users can spend their on-chain assets as easily as cash.
  • “Essentially, they're the actual bridge between the off-chain traditional financial system and the new emerging DeFi and stablecoin system.”
    • The Bridge: Unlike the old model where centralized exchanges were the only bottleneck for moving money, neobanks create countless on/off ramps. They allow users to hold their net worth on-chain while seamlessly interacting with the real-world economy.
    • Better UX: Platforms like Ether.fi are not building banks from scratch; they are building superior user experiences on top of existing licensed partners. This allows them to focus on programmable features like combining risk-free yield with cash-back rewards, creating products traditional cards can't compete with.

Frax: The Pipes, Not the Storefront

  • Frax is positioning itself not as a consumer-facing neobank but as the underlying infrastructure powering them. The strategy is to provide a compliant, versatile stablecoin (FRAXUSD) and a white-label issuance platform that allows any project to launch its own branded stablecoin without reinventing the wheel.
  • “We want to be the underlying digital dollar. We don't want to actually issue our own card or have a specific bank exclusivity.”
    • Infrastructure Play: Frax provides the API endpoints and SDKs that allow neobanks like Ether.fi to integrate a compliant digital dollar, backed by real-world assets from custodians like BlackRock and Fidelity.
    • Positive-Sum Game: Frax’s model aligns incentives. By building interoperable pipes and partnering with multiple RWA providers, its growth directly benefits the entire ecosystem, increasing AUM for its partners and creating a wider network effect.

The Trojan Horse to Displace Visa

  • The ultimate goal extends far beyond just better bank accounts. Crypto-powered debit cards are a coordination mechanism—a Trojan horse to onboard millions into a stablecoin-native economy. By settling stablecoin payments over existing Visa rails, they get users comfortable transacting on-chain without merchants even noticing.
  • “Once we have a critical mass of people paying with stablecoins, we don't need Visa anymore... We can just rip Visa out of the whole system.”
    • Solving the Coordination Problem: Instead of waiting for every merchant to put up a "USDC Accepted Here" sign, neobank cards make stablecoins spendable everywhere Visa is accepted.
    • A Closed-Loop Economy: As adoption grows, the system can bypass traditional payment networks entirely. This enables a fully on-chain, self-sufficient economy where value is created, spent, and recirculated without ever leaking back into the legacy financial system.

Key Takeaways

  • The Real Metric Is GDP, Not Volume. A million dollars in daily card spending on real-world goods is a far more powerful signal of adoption than hundreds of millions in AMM swap volume. Watch the growth in real economic activity, not just on-chain shuffling.
  • Infrastructure Is the Bottleneck. The race isn't just to launch another neobank; it's to build the underlying pipes. Protocols like Frax that power multiple stablecoins and neobanks are positioned to capture value from the entire ecosystem's growth.
  • The End Game Is a Parallel Financial System. Crypto neobanks are the final link needed to close the economic loop. They enable a world where a user can save, earn yield, and spend entirely on-chain, making the concept of a bank account obsolete.

Defining the Crypto Neobank Revolution

  • Sam Kazemian, founder of Frax, kicks off the discussion by defining a neobank as a fintech "wrapper" built on top of traditional licensed banks to provide a superior user experience. Examples include Revolut and Mercury. He argues that crypto is now at an inflection point where it can offer a similarly seamless experience, solving the long-standing problem of complex user onboarding.
  • Neobank: A company that offers digital banking services through a user-friendly app, typically by partnering with a licensed bank rather than holding a banking license itself.
  • Sam explains that the rise of stablecoins and clearer regulatory guidance are enabling this shift. Previously, centralized exchanges were the primary, and often clunky, on-ramps. Now, crypto neobanks are blurring the lines between the traditional financial system and the on-chain world.
  • A crypto neobank integrates stablecoins directly into a banking-like platform, allowing users to spend their on-chain assets in the real world through debit cards and other financial tools. Sam notes, "Essentially, they're the actual bridge between the off-chain traditional financial system and the new emerging DeFi but also stablecoin system."

Frax's Strategy: Powering the Ecosystem as an Infrastructure Layer

  • Sam clarifies that Frax is not building its own consumer-facing neobank or card. Instead, its strategy is to provide the core infrastructure—specifically its FRAXUSD stablecoin—that other neobanks and fintech platforms can build upon. This positions Frax as a foundational "digital dollar" for the emerging ecosystem.
  • Frax is partnering with platforms like Ether.fi to integrate FRAXUSD as a core asset, allowing users to spend it via their cards.
  • The goal is for FRAXUSD to achieve a large Total Addressable Market (TAM) as a payment and savings instrument, competing with giants like USDC and USDT for the "money TAM."
  • Sam introduces a key distinction between stablecoins:
    • Digital Dollars: Stablecoins like FRAXUSD, USDC, and USDT that aim to function as real money for payments and settlement.
    • "Stablecoin Gift Cards": Branded stablecoins (e.g., a hypothetical "Starbucks USD") that are useful within a specific ecosystem but are not intended for broad, cross-border settlement.

The Interoperability Play: Building the Pipes for All Stablecoins

  • A core part of Frax's strategy is its white-label issuance platform, FraxNet. This platform allows other projects to issue their own branded stablecoins using Frax's existing infrastructure, including its regulatory-compliant backing and multi-chain connections.
  • FraxNet: An on-chain fintech platform designed to align with emerging US regulatory frameworks, allowing users to mint, redeem, and use FRAXUSD.
  • Sam highlights a critical competitive advantage: interoperability. While other issuance platforms like Ethena's or M0's create siloed ecosystems, Frax aims to connect them.
  • "If you can be interoperable with as many of these pipes as possible, that's the real value for a new stable coin coming into the industry," Sam states, emphasizing Frax's goal to be the neutral backbone for the entire stablecoin market.
  • This interoperability is achieved by integrating with a wide range of RWA (Real-World Asset) providers like BlackRock, Superstate, and Fidelity, whose tokenized treasuries serve as collateral. This diversified, multi-party approach creates strong economic alignment across the ecosystem.

The Trojan Horse Strategy: How Neobanks Will Replace Visa

  • Sam outlines a profound long-term vision where crypto neobank cards act as a "Trojan horse" to disrupt traditional payment networks. Initially, these cards use Visa's rails to make stablecoins spendable everywhere, solving the merchant adoption problem.
  • When a user swipes a card from Ether.fi or Ipay, their stablecoins are converted and settled on the Visa network. The merchant doesn't even know crypto was involved.
  • This creates a seamless user experience with added benefits like high yield on stablecoin balances, which can fund superior cashback rewards (e.g., 7-8%) that traditional cards cannot match.
  • The strategic endgame: once a critical mass of consumers and merchants are using these cards, the system can bypass Visa entirely. Payments can occur directly, peer-to-peer, using stablecoins on dedicated payment blockchains.
  • Sam asserts, "These are coordination mechanisms to actually just blur the abstraction between the traditional banking system and the crypto system."

A New Coordination Problem: The Rise of Payment-Specific Blockchains

  • While neobanks solve the initial coordination problem, they introduce a new one: which blockchain will become the standard for these new payment flows? Sam acknowledges the proliferation of specialized chains aiming to capture this market.
  • Chains like Tempo, Stelo (for Tether), Plasma (for USDT), and Frax's own Fraxtal are all competing to be the settlement layer for this new on-chain commerce.
  • This leads to a classic standards competition, humorously compared to the XKCD comic where creating a universal standard results in one more competing standard.
  • Strategic Insight: Investors should monitor which of these chains gain real-world adoption and network effects, as first-mover advantage in payment flows will be critical.

Stock vs. Flow: Ethereum's Role as the Ultimate Savings Layer

  • To analyze the blockchain competition, Sam introduces the "Stock vs. Flow" framework. He argues that different chains will specialize in different functions, with Ethereum solidifying its role as the ultimate settlement and savings layer.
  • Stock (Savings): The total value of assets held. Sam argues that high-value assets and stablecoin issuance will remain on Ethereum due to its unmatched security and decentralization. He shares an anecdote of a large investment bank choosing FRAXUSD specifically because its RWA collateral is on Ethereum, which they view as a chain that "doesn't go down."
  • Flow (Payments): The volume of transactions. These high-frequency, low-value transactions will migrate to specialized Layer 2s or alt-L1s optimized for speed and low cost.
  • Investor Takeaway: This framework suggests a multi-chain future where value accrues to both the secure base layer (Ethereum) and the high-throughput payment layers. The key is to identify which chains are winning in each category.

The Net Worth Theory: Closing the Economic Loop

  • The conversation culminates in Sam's "Net Worth Theory," which explains why a self-sufficient crypto economy is inevitable. The theory posits that people prefer to hold their liquid cash (dollars) in the same ecosystem where the majority of their net worth is located.
  • As more assets—from crypto-native tokens to tokenized equities—move on-chain, users will have less reason to off-ramp to traditional banks.
  • Crypto neobanks provide the final missing piece: a way to spend on-chain wealth in the real world without ever touching a traditional bank account.
  • This creates a closed-loop system where value is generated, saved, and spent entirely on-chain, marking a pivotal step toward a truly "bankless" world.

Why Checking and Savings Accounts Are a Fundamental Economic Law

  • Sam concludes with a fascinating insight into stablecoin design, arguing that the separation between payment-focused stablecoins (like FRAXUSD) and yield-bearing savings stablecoins (like sFRAXUSD or Ethena's sUSDe) is not an artifact of traditional finance but a fundamental economic principle.
  • Payment Stablecoins (Checking Accounts): Must be simple, risk-free, and easily understood to minimize friction for merchant adoption. Every new party accepting the coin should not have to perform complex risk analysis.
  • Yield-Bearing Stablecoins (Savings Accounts): Are inherently opinionated and carry risk from their underlying yield strategies. They are designed for holding and earning, not for widespread, frictionless payments.
  • This distinction explains why Frax evolved to offer two separate products, reflecting a natural market structure that optimizes for both seamless payments and risk-adjusted yield.

Conclusion

This episode highlights that crypto neobanks are not just a new product category but a strategic vehicle for achieving a fully circular on-chain economy. For investors and researchers, the key is to track real-world payment volumes and stablecoin integrations, as these metrics will signal which platforms are successfully bridging the gap to mainstream adoption.
