Vilhelm German: Crypto Exchanges Have More to Worry About Than Trading Volume

Crypto exchanges are taking on a bigger role in financial markets. They are supporting more assets, operating across multiple jurisdictions and facing higher demands for security, uptime and regulatory compliance. Behind the interface, trading, custody, liquidity, compliance and security systems all have to work together, and keep working when markets become volatile. That complexity is growing as exchanges expand beyond cryptocurrencies into tokenized real-world assets, each bringing its own trading, settlement and regulatory requirements. Vilhelm German, a long-time crypto infrastructure executive and CTO at Bitnuk crypto exchange, looks at what this shift means for exchange technology –  from the rise of AI-driven threats and embedded compliance to infrastructure resilience under market stress. “The question isn’t how many features an exchange has,” German says. “It’s whether the infrastructure can keep everything running securely and reliably when the pressure is on.” From Product Layer to Infrastructure For years, crypto exchanges competed on the surface: trading pairs, chart tools and staking yields. That competition hasn’t disappeared, but the harder engineering work now happens underneath, says Vilhem German, the man behind developing one of the first Swiss-regulated crypto exchanges back in 2018. A platform now has to run a matching engine that stays fast under bursty load, keep custody synced across a dozen or more blockchain networks, route to external liquidity providers without introducing latency, and increasingly do all of that for tokenized stocks and commodities alongside crypto — each with its own settlement logic and market hours. “The interface is maybe five percent of the engineering effort at this point,” says Bitnuk’s CTO. “The other ninety-five percent is making sure that when a user hits ‘withdraw,’ the system knows exactly which chain, which custody tier, and which compliance check that withdrawal needs to pass — in under a second, and correctly, every time.” The wider the range of assets a platform supports, the harder it becomes to keep these systems connected and reliable. AI Is Changing the Security Equation Security architecture — access control, custody segmentation, incident response — used to be evaluated mainly against human attackers probing for weak points. That assumption doesn’t hold anymore in the era of AI. Early 2026 marked a turning point in crypto security, as attackers began using AI to make fraud more targeted, automated and harder to detect. Generative AI enabled highly personalized phishing, automated vulnerability discovery and increasingly convincing voice and video deepfakes, while attacks began targeting AI agents themselves. As users increasingly delegated wallet activity to AI, the threat shifted from stealing credentials to manipulating the agents authorized to move funds. Crypto exchanges are also using AI defensively, including for real-time fraud detection, behavioral analysis, smarter order routing and predictive liquidity management. “We stopped seeing ‘we caught a phishing attempt’ as a win,” says German. “The real threat is scale. If the exchange’s defence system can’t detect thousands of AI-driven attempts with constantly changing patterns, it is already behind.” To stay ahead of AI-powered threats, crypto exchanges need stronger controls around AI trading agents, including real-time prompt-injection detection and sandboxing to test suspicious transactions before execution.  They should also use hardware-based authentication to limit deepfake-driven attacks and continuously test their systems with AI-powered red-team tools. Compliance Moves Into the Core 2026 also marks the year when regulatory transition periods have officially ended in certain jurisdictions, making non-compliance a serious threat to crypto exchanges.  With frameworks such as the EU’s MiCA and global FATF Travel Rule requirements coming into full force, operating without embedded compliance can restrict access to traditional banking rails, expose executives to personal liability and trigger enforcement action. “In a market where institutional liquidity and user trust depend on verified, audit-ready operational resilience, compliance can no longer be patched onto trading engines,” says German. “It must be built into the platform’s core infrastructure.”  KYC/AML checks, transaction monitoring, risk scoring and jurisdiction controls must run directly within trading and withdrawal systems, not as separate layers. The challenge is enforcing these controls without adding latency or compromising performance and user experience.  For exchanges operating at scale, that means rethinking core infrastructure rather than treating compliance as an additional layer. Engineering for Market Stress A platform’s reliability is best tested not when markets are calm, but when volatility spikes. It shows up when the market moves 15% in an hour, trading volume spikes, withdrawal requests surge, and the same infrastructure has to keep matching orders, syncing custody, and enforcing compliance checks — all at once, all correctly. An exchange’s technology readiness should therefore be measured not just by everyday performance, but by how it holds up under extreme market conditions. “Tech readiness means simulating extreme volatility, network congestion, and attack vectors simultaneously so the real event feels routine,” says Vilhelm German. Trust Becomes the Differentiator For exchanges, the competitive advantage is increasingly about how reliably the entire system performs when it matters most. As crypto moves closer to mainstream finance, platforms will have to operate securely, comply across jurisdictions and remain available under pressure. “We’ve officially exited the era where crypto exchanges could operate like move-fast-and-break-things tech startups,” concludes Bitnuk’s CTO. “We are building real financial infrastructure now.”  That shift puts the focus where it belongs: not just on what a crypto exchange can offer, but on whether users can trust it to keep working when they need it most.
