This Is The Infrastructure Crypto Needs Before Institutions Can Truly Arrive: Phylax CEO

Crypto has spent the better part of the last two years celebrating the arrival of institutions.

Bitcoin ETFs have opened the floodgates for traditional investors. Stablecoins are becoming a strategic priority for banks and payment companies. Tokenized Treasury funds have grown into one of the industry's fastest-growing sectors. Every week seems to bring another announcement from a major financial institution experimenting with blockchain technology.

But beneath the optimism lies a more uncomfortable reality: The infrastructure that institutions expect from financial markets still doesn't fully exist onchain, and 2026 brought one of the worst months for DeFi exploits in history.

On the other hand, traditional finance has spent decades building safeguards that most investors never think about. Circuit breakers halt trading during periods of extreme volatility. Risk controls stop erroneous transactions before they settle. Exchanges maintain systems designed not just to react to failures, but to prevent them from cascading throughout the financial system.

Starting from a different philosophy, crypto has had to re-learn a lot of the same TradFi mistakes, while building its own set of tools to patch errors or hacks. But once funds move, there is often no administrator capable of reversing a mistake — and certainly no Fed, or lender of last resort coming to save anyone.

That design has unlocked enormous efficiencies, but it has also created a unique category of risk.

"A hack is a physics event," Phylax CEO Odysseas Lamtzidis tells Coinage in a new interview. "It's like aerospace. If there's an error on the plane, it goes down."

It's an analogy that captures what makes blockchain security fundamentally different from traditional finance.

In conventional markets, a back-office error or operational mistake can be costly, but it can usually be corrected. Crypto rarely offers such a luxury.

"There is a lot of the same lessons," Lamtzidis said of traditional finance, "but there is also a whole new aspect because traditional finance does not have instant settlement."

"So an error on the Excel sheet — it will cost a couple million dollars, but at the end of the day they go back and update the ledger," he said. "In crypto... mistakes are irrevocable."

That reality has become increasingly expensive for decentralized finance. Exploits have cost the industry billions of dollars over the past several years, with even heavily audited protocols continuing to fall victim to sophisticated attacks. Most security tooling today focuses on detecting exploits after they begin — allowing teams to monitor suspicious activity and attempt to limit the damage.

But by the time monitoring systems identify an attack, the funds have often already left.

Lamtzidis says Phylax is trying to move that line of defense earlier. Rather than simply observing transactions, the company's technology operates alongside blockchain infrastructure, allowing protocols to define their own security policies before transactions are finalized. If a transaction violates those rules, it never reaches the blockchain.

Lamtzidis describes it less as surveillance and more as a circuit breaker.

"What we built is an onchain circuit breaker that runs at the network level," he said. "It allows protocols to prevent catastrophic events like hacks happening on them."

Of course, circuit breakers in traditional markets are common. Exchanges like the New York Stock Exchange have long relied on mechanisms designed to stop cascading failures before they spiral into broader market disruptions. Crypto has largely lacked an equivalent.

The need has become more obvious as decentralized finance has become increasingly interconnected. A vulnerability in one protocol can quickly ripple through lending markets, liquidity pools and derivatives platforms because nearly every application composes with another.

"What we saw was contagion," Lamtzidis said. "You had a system exploit on one part, and then it became a whole systemic risk because of composability."

Importing ideas from Wall Street into crypto has often been controversial, particularly among those who worry additional controls could undermine decentralization. Lamtzidis says that concern shaped Phylax's design from the beginning.

Rather than creating a centralized authority capable of censoring transactions, each protocol chooses its own rules.

"Only each protocol can enforce its own policies," he said. "There is an opt-in element. There is no coercion." That distinction may prove increasingly important as institutional capital continues moving on-chain.

For years, crypto investors were largely willing to accept extraordinary levels of risk in exchange for extraordinary returns. But that equation is changing as Treasury yields compete directly with compressing opportunities in DeFi.

"For the first time," Lamtzidis said, "we're encountered with a question: When an investor comes in and I give them a yield, is that yield competitive versus the 4% they can take on Treasuries?"

That realization, he argues, is forcing the industry to mature. Sustainable yields alone are no longer enough. They also have to be accompanied by institutional-grade risk management.

Importanly, before founding Phylax, Lamtzidis worked at Nomad, the cross-chain bridge that suffered one of crypto's largest exploits in 2022 after a vulnerability allowed hundreds of millions of dollars to be drained.

"I had two choices," he joked. "Either get severely depressed or do something about it."

The larger question facing crypto is whether these kinds of protections become standard infrastructure — or remain optional. Banks, asset managers and payment companies are unlikely to build businesses atop infrastructure where a single software exploit can instantly erase hundreds of millions of dollars with little possibility of recovery.

Crypto has often framed security as an application-level problem. Institutions are beginning to treat it as market infrastructure.

If blockchain technology is going to underpin the next generation of financial markets, it may ultimately need to inherit not just Wall Street's capital, but many of the safeguards that made those markets resilient in the first place.
