When we talk about crypto neobanks, the conversation often focuses on slick mobile apps and user experience. Sure, the interfaces are polished and intuitive—but that's not what makes them revolutionary. The real innovation is happening in the pipes—the infrastructure layer that moves money across borders, blockchains, and legacy systems.
The future of digital banking isn't just about better apps. It's about fundamentally better rails.
Stablecoins: The New Money Highways
Crypto neobanks are fundamentally different from traditional digital banks because of what powers them: stablecoins. While traditional neobanks rely on legacy payment rails like SWIFT, ACH, or SEPA, crypto neobanks use blockchain-based stablecoins to move value across networks with unprecedented speed and efficiency.
As we explored in our previous analysis of Bitcoin Lightning Network's role in global payments, we're witnessing a fundamental shift in how money moves globally. But stablecoins represent a different approach to the same problem: eliminating friction in cross-border payments.
Cards are linked to custodial wallets. Users spend like they always have. But behind the scenes, the money is moving on entirely different rails.
Bridge: Orchestrating the Invisible Revolution
One company exemplifying this infrastructure shift is Bridge. Rather than building consumer-facing products, Bridge orchestrates cross-network transactions invisibly, bridging legacy account systems to blockchain rails.
The impact? Real-world corporate treasury operations moving at blockchain speed.
Zach Abrams, founder of Bridge, recently shared a telling example: Stripe moved $14 million to Mexico using stablecoins. The comparison is stark:
- Traditional rails: T+2 days
- Bridge: Less than 2 hours
"Corporate treasury is one of the largest unlocks for stables," Abrams noted. "We're finally upgrading global treasury flows from dial-up to fiber."
Stripe's Stablecoin Integration: From Product to Operations
What makes this particularly significant is that Stripe isn't just incorporating stablecoins into its product offerings—it's embedding them throughout the company as a core tool for operational efficiency.
This week, Stripe's Treasury team started using stablecoins to rebalance its own internal treasury between the US and Mexico, similar to how other customers like SpaceX and DFelix use Bridge.
The Stablecoin Sandwich
Abrams explained why the transfer took two hours rather than being instant: "A stablecoin sandwich includes two legs, USD→stablecoin and stablecoin→MXN. Unfortunately, we are still dependent on the US payments system (in this case wires) to mint stablecoins, which can take anywhere from 10-120 minutes to leave Bridge's bank and land at the issuers. Once on-chain, sending wallet to wallet, trading into MXN, and sending via SPEI take minutes."
As he put it: "A small step for stablecoins, but a giant leap for further adoption. In time we'll be able to get this down to minutes end-to-end, but it's already a 10x improvement over multi-day settlement."
Card Networks Meet Blockchain
The convergence of traditional card networks with blockchain infrastructure represents another critical development. Mastercard and Visa have both plugged their card systems into blockchains, enabling settlement in stablecoins.
This is where Bridge's orchestration capabilities become crucial. Bridge helps with the issuance and management of stablecoins across different blockchain networks. Crypto neobanks can issue cards on custodial wallets, allowing users to spend and move money around the world—without ever knowing the underlying technology powering their transactions.
Some companies are taking this even further by building their own Layer 2 blockchain solutions. Coinbase launched Base, its own L2 chain, to provide faster and cheaper transactions for its ecosystem of services and products.
Bitcoin's Lightning Fast Settlement Layer
While stablecoins dominate the crypto neobank conversation, Bitcoin's Lightning Network represents a parallel infrastructure revolution.
Lightspark, led by former Facebook Messenger chief David Marcus, is enabling any company to integrate Bitcoin as a settlement network. They're using the Lightning Network combined with their own Layer 2 network called Spark to facilitate instant, low-cost Bitcoin payments.
Strike pioneered this approach. The company was the first to use Bitcoin as a settlement layer, enabling transfers between currencies like EUR→BTC→USD. By using Bitcoin as an intermediary currency, Strike bypasses traditional correspondent banking relationships entirely.
More recently, Block's Cash App enabled merchants to be paid in Bitcoin, extending Bitcoin's reach into everyday commerce.
Connecting to Legacy Infrastructure
Here's what makes this infrastructure shift truly powerful: all these blockchain networks—whether stablecoin rails or Lightning Network—connect seamlessly to legacy systems like the Federal Reserve's network, SWIFT, and SEPA.
The integration is bidirectional. Fiat money enters the crypto ecosystem through on-ramps, moves at blockchain speed, then exits through off-ramps back into traditional banking systems when needed.
When Infrastructure Becomes Invisible
The best infrastructure disappears.
Most people don't know what TCP/IP is. They don't understand SMTP protocols. Yet these technologies power every email and website they use daily. The same will be true for blockchain-based payment infrastructure.
One critical element that will accelerate adoption: cost of settlement.
Settlement through Lightspark's Bitcoin Lightning Network is cheaper than traditional payment systems like Mastercard and Visa. This isn't theoretical—it's already creating new business models.
We're seeing a proliferation of Bitcoin cashback cards where rewards are paid in Bitcoin rather than fiat currency. Why? Because the underlying fees are lower than traditional card networks, allowing companies to offer more generous rewards while maintaining profitability.
Neutrality: Bitcoin's Unique Advantage
There's one big differentiation between Visa/Mastercard networks and other private or corporate blockchains: Bitcoin is neutral, and no one owns it.
Corporate blockchains like Base (Coinbase), or private stablecoin networks, are controlled by single entities. While this allows for faster governance and decision-making, it also creates centralization risks.
Bitcoin's Lightning Network, by contrast, is built on a decentralized protocol. No company can change the rules unilaterally. No entity can freeze your funds. This neutrality makes Bitcoin particularly attractive for international settlement where trust in intermediaries may be limited.
The Beginning of Blockchain Utility
We are clearly at the beginning of the utility trend for blockchain and Bitcoin.
For years, cryptocurrency was dominated by speculation and trading. Now, we're seeing the infrastructure mature into practical tools for moving money, settling payments, and managing corporate treasury operations.
Stripe using stablecoins for internal operations. SpaceX using Bridge for payments. Merchants accepting Bitcoin through Cash App. These aren't experiments—they're operational deployments by major companies handling real money.
The crypto neobank revolution isn't about replacing banks with crypto. It's about upgrading the pipes that move money globally—making them faster, cheaper, and more accessible to everyone.
As David Marcus, CEO of Lightspark, discusses in his recent interviews, we're building the infrastructure for a more open, interoperable financial system. The question isn't whether blockchain-based payment rails will be adopted. It's how quickly traditional finance will adapt to this new reality.
The infrastructure is ready. The pipes are built. Now comes the adoption phase.
