Blockchain as B2B Payment Infrastructure

Watch on YouTube

While in Paris, we had the chance to interview Merita Spahiu from CashXChain and discuss the real-world issues stablecoins can be used to solve.

Key takeaways

  • CashXChain is a B2B payment provider that moves money on-chain with stablecoins on Solana, while customers see a simple app.
  • The idea came from a co-founder's father, whose drone supplies from China to Germany were delayed by slow, costly bank payments.
  • The young team closed its first fundraise from an investor and says it holds several patents on its combined technology.
  • Licensing can cost up to 500,000, so CashXChain is partnering with licensed crypto providers in the short term.
  • Merita is also building AI compliance software that connects to open business data to speed up KYC and KYB decisions.
  • She wants Kosovo, and remittances from the Albanian diaspora, to be the first test case when CashXChain expands to consumers.

A young team tackling cross-border payments

Recorded at Proof of Talk at the Louvre in Paris, this Hodl Up episode features Merita, a founding member of CashXChain on the finance side. She is one of the youngest builders the hosts have met and the podcast's first Albanian guest, which gave the conversation a personal angle for the Kosovo-based team.

"We are a payment provider, and we deal with B2B businesses, providing payments for them," Merita said. The conversation covers how the idea started, what sets CashXChain apart from giants like PayPal, how it plans to scale, her new compliance project and why Kosovo could be its first consumer market.

How CashXChain started

Co-founder Valentin saw the problem up close. His father sold drones and bought from a supplier in China, with goods shipped to Germany. Payments were slow, manual and expensive, sometimes delaying deliveries by days. "If you use banks or Western Union, the fees are just way too high," Merita said.

The team decided to build a payment infrastructure on blockchain. CashXChain runs on Solana and uses stablecoins so value stays steady across borders. The project started about a year before this recording, raised its first round and was preparing to launch within weeks. Press coverage in Germany and Canada called the team teenagers taking on PayPal, which Merita said turned their age into an advantage. "Our age was actually a big plus."

What sets CashXChain apart

Merita pointed to three differences: real-time transfers, responsibility for customer funds, and flexibility. "If I'm sending money to you, it arrives in real time." While PayPal applies the same standard to everyone, CashXChain listens to individual businesses. One German customer buying from Kenya told them banks were simply too slow, so the team began building around that problem.

The table below compares traditional payments with the CashXChain approach, based on Merita's description.

Scaling carefully

Following their mentor's advice, the team will scale step by step. "We're not going to launch and say, 'Okay, we're available for everybody,' because it would become chaos." B2B comes first, with consumer payments likely years away. Winning businesses is hard, since many resist switching providers, so marketing and sales are now priorities.

Licensing is another hurdle. Merita said it can cost up to 500,000, so CashXChain is partnering with licensed crypto providers for now while aiming for its own license later. "It's a safety symbol." Security is critical: moving a million across borders means any error could leave the company covering the loss.

A second project: faster compliance

A delayed US bank account opening, blocked by slow compliance, kept Merita from attending a blockchain event. That frustration inspired a second project: AI software for compliance officers handling KYC and KYB. It connects to open business data through APIs, checks documents and ultimate beneficial owners, and flags sanctioned entities or high-risk jurisdictions. "We just want the market to not stop. We want it to flow like water."

Kosovo as the first consumer test case

The hosts noted that Kosovo relies heavily on remittances, citing about €1.3 billion a year, much of it sent through costly services. Merita agreed. "When we move from B2B to B2C, our first real test case will be Kosovo." She plans to reach both people in Kosovo and the diaspora.

She believes trust is the barrier, recalling her mother urging her to become a doctor instead. Her answer is to hide the complexity. Users send money by username, and "it's all in the back end."

FAQ

Frequently asked questions

What is CashXChain?

CashXChain is a B2B payment provider that uses stablecoins on Solana to move money across borders in real time. Blockchain runs in the back end, so businesses send and receive funds through a simple interface using usernames instead of wallet addresses.

How is CashXChain different from PayPal?

Founding member Merita says CashXChain offers real-time transfers, takes responsibility for customer funds and tailors its service to each business. PayPal applies one standard to everyone, while CashXChain builds around individual pain points, starting with B2B payments.

Can stablecoins lower remittance costs for Kosovo?

Merita believes they can. Many Kosovo families receive money from relatives abroad through costly services like Western Union. CashXChain plans to make Kosovo its first consumer test case, offering faster, cheaper stablecoin transfers hidden behind a simple app.

Why don't small fintechs get their own license?

Merita says payment licenses can cost up to 500,000, which is hard for an early-stage startup to justify. CashXChain is partnering with licensed crypto providers in the short term and plans to obtain its own license once it grows.
