Kaledora Fontana Kiernan-Lin puts a timeline on her bold prediction: the global contract-for-difference (CFD) brokerage market faces a major disruption within five years due to decentralized finance.
The co-founder and CEO of Ostium, a blockchain-based perpetual swaps platform, recently secured $20 million in Series A funding from General Catalyst and Jump Crypto to support that thesis.
In an interview with FinanceMagnates.com, Kiernan-Lin explained why she believes retail currency and commodity traders will abandon traditional CFD brokers for on-chain alternatives that offer transparent pricing and self-management of funds.
“The ‘perpification’ of markets – where every asset becomes a liquid, tradable perpetual exchange – is the inevitable end state,” Kiernan-Lin said. She expects retail currencies and commodities to crack first, calling them “markets where users currently pay exorbitant fees for opacity.”
Whether that vision will become a reality on her timeline remains an open question. Decentralized finance platforms face their own set of challenges, including smart contract vulnerabilities, liquidation risks due to high levels of debt, and a lack of comprehensive regulatory frameworks that have plagued the crypto derivatives sector.
Ostium is not alone in focusing on traditional assets. Major crypto exchanges are in a race to capture TradFi’s trading volume, especially during the recent metals rally.
Binance launched 24-hour perpetual contracts on silver in early January as silver prices surged 150% year-over-year, while rival Bitget rolled out similar offerings targeting gold, forex and global macro assets.
BingX reported that record gold prices drove half of TradFi’s $1 billion in trading, with gold futures contracts alone generating more than $500 million in daily volume.
The trend goes beyond perpetual swaps: Coinbase and Crypto.com have acquired CFD licenses, indicating that well-funded fintech players with large user bases are eyeing the retail derivatives market.
These moves suggest that Kiernan-Lin’s thesis on the demand for TradFi assets is not merely aspirational. But they also highlight the competitive dynamics at play, with established crypto exchanges leveraging existing liquidity and brand recognition to capture the same offshore trading cohort that Ostium is targeting.
Record volumes indicate early traction
Ostium’s recent performance seems to confirm at least part of that vision. The platform hit a record $711 million in single-day trading volume on Jan. 30, as metal prices soared, with silver and gold trading accounting for about half of that total. More than 95% of Ostium’s open interest is now in traditional markets rather than crypto assets, an unusual profile for a blockchain-based exchange.
Cumulative trading volume has surpassed $33 billion since launch, including more than $5 billion in metals alone. The rise matches the rally in precious metals, which saw silver hit a record $120 an ounce in late January and gold soar above $5,600.
fourth day in a row that ostium hits fresh ATHs:
>$2.5 billion L7D volume
> $711 million in 24-hour volume
> $250 million of that in silver alone
> another $250 million in copper + gold
> 4,000 WAUs exceeded
> $339 million in open interest
> 100% uptime during the day with the highest volume ever for metals

Traders on the platform posted $5.8 million in profits on January 30, the highest single-day profit in Ostium history, reversing previous cumulative losses. Just two days earlier, the same cohort had suffered $2.7 million in losses.
Eliminating the problem of the broker as a counterparty
Kiernan-Lin’s pitch focuses on a structural critique of the CFD model. When retail traders lose money on traditional platforms, which happens to 76-82% of them according to regulator disclosures, the broker often profits directly by taking the other side of those trades. British regulators have repeatedly pointed out this conflict of interest.
However, Ostium claims that its architecture routes transactions through institutional liquidity platforms and executes them on-chain via smart contracts built on Arbitrum, an Ethereum Layer 2 network.
“When you trade oil on Ostium, the quote is derived from institutional liquidity and anchored by our oracle infrastructure, then executed onchain,” Kiernan-Lin explains. “Once a position is open, the protocol cannot arbitrarily increase spreads, change financing terms, freeze accounts or introduce new restrictions.”

She argues that the real benefit lies not just in who is on the other side of a transaction, but that pricing, financing and execution follow transparent, programmatic rules rather than discretionary decisions by brokers.
Legacy brokers retain broad power to adjust spreads, adjust funding costs, or limit accounts during volatile periods, actions that are theoretically impossible on Ostium’s smart contract infrastructure.
Yet smart contracts introduce their own risks. The Financial Stability Board (FSB) has warned that decentralized finance platforms face vulnerabilities related to flawed code, market manipulation through voting with governance tokens and concentration risks with third-party infrastructure providers.
Offshore markets and regulatory gray areas
Ostium explicitly targets offshore CFD traders, particularly non-US investors looking for exposure to US stocks and commodities. Kiernan-Lin describes the pain point as access: traders in Vietnam or the Philippines typically navigate offshore entities “with questionable solvency, high withdrawal difficulties and the real risk of unexpected account freezes.”
The platform operates as a non-custodial technology provider, meaning Ostium itself does not hold customer funds, but the smart contracts do.

“We respect local laws; our primary focus is to replace the trading infrastructure with one that does not require a user to trust a centralized entity in a jurisdiction they cannot sue,” Kiernan-Lin said.
The strategy reflects how offshore CFD brokers have historically operated in regulatory gray zones, raising questions about whether decentralized infrastructure truly solves investor protection issues or simply moves them to another layer of the technology stack.
Self-management as a feature, not a bug
The CEO reframes self-control, often seen as a technical barrier for retailers, as the platform’s killer feature.
“No one can freeze your money,” she said, arguing that this is more compelling than the ease of fiat deposits with traditional brokers once traders experience the difference.
Ostium has designed its onboarding so that “connect wallet” replaces traditional login details. There is no three-day waiting period for transfers, and the platform is exploring account abstraction technology to make the wallet experience “invisible to those who want it.”
Kiernan-Lin believes that once traders realize that holding their own margin means they never have to wait for a broker to approve a withdrawal, the perceived barrier becomes a preference.
The flip side is that self-control also means self-responsibility.
Cost structure and competitive position
When pressed on the fees, Kiernan-Lin acknowledged that Ostium may not win “a comparison based on advertised foreclosure costs alone” against large incumbents like IG or Pepperstone. Entry spreads at traditional brokers can look cheaper at first glance.
Where Ostium claims to differentiate is in the predictability of costs. The gas costs on Arbitrum are minimal and visible in advance. Execution fees and funding rates are explicit and known before a position is opened.
“There are no hidden spread charges, unexpected swap fees or discretionary account actions that change the economics of a position after it has been opened,” Kiernan-Lin said.
Traditional “zero commission” pricing often masks variable spreads, opaque financing and operational risk, she argued. However, perpetual swaps have their own cost structure that can affect profitability.
Derivatives over tokenized equity
Kiernan-Lin sees limited trading appeal in true tokenized equity ownership compared to derivatives.
“It’s capital efficiency,” she said. Traders betting on earnings calls or macro events don’t want to hold on to 100% of the capital to buy stocks when they can express the same opinion with a fraction of that capital through derivatives.
“The foreign exchange market trades $7.5 trillion a day, not because people want to own euros, but because they hedge or speculate on the price,” she noted.
An opposing view is held by Robinhood CEO Vlad Tenev, who sees tokenization as “the biggest innovation in capital markets.”
She also has a different view on prediction markets like Polymarket and Kalshi, calling them “highly complementary” rather than competitive.
The Vision 2030
Kiernan-Lin expects that by December 2030, the term “Real World Asset” will no longer exist, as all assets will exist on-chain. Ostium will not be labeled a ‘crypto platform’, but rather a backend infrastructure for some of the global macro trading.
some thoughts on the weekend liquidation hunt…
– 24/7 RWA offender markets are very cool in theory! but the disadvantages of their illiquidity over the weekends – constant trading without a real, liquid spot price – outweigh the advantages. these disadvantages are greater the older you are…

“Decentralized protocols won’t just disrupt part of the market; they will boost the growth of the market itself,” Kiernan-Lin added, drawing a parallel to how Uber expanded the taxi market by orders of magnitude while upending the industry. She positions Ostium as the “standard bearer for that shift.”
That timeline assumes several things go right: regulatory frameworks evolve to enable decentralized platforms without crushing them, smart contract security matures to prevent the kinds of exploits that have plagued DeFi, and retailers appear willing to trade traditional protections for transparency.
Meanwhile, traditional CFD brokers are not standing still. Around 80% of European CFD firms are considering a move to listed derivatives amid regulatory pressure, suggesting the industry itself is adapting to survive.
