Interviews

Cross Asset Trading Discussion #01

On March 12, 2026, Kaledora Kiernan-Linn appeared on ''The Crypto Tape'', a program produced by GSR and hosted by Frank Chaparro. The discussion focused on Ostium, trading activity among crypto-native users, and developments related to on-chain financial markets.

During the interview, Kiernan-Linn stated that Ostium was established in 2022 with the objective of providing access to multiple traditional asset classes through blockchain-based infrastructure. He said that the platform initially focused on commodities before expanding to include foreign exchange markets, indices, and equities. Kiernan-Linn also stated that gold trading volume on Ostium reached approximately US$6 billion during the second half of 2025 and exceeded Bitcoin trading volume on the platform during that period.

Kiernan-Linn discussed the relationship between macroeconomic events, geopolitical developments, and trading activity across different asset classes. He stated that prediction markets and event-driven trading had become more common among some crypto-native traders and described prediction markets as one of several mechanisms through which users engage with broader financial markets.

The interview also included comments regarding Ostium’s interface design and trading structure. Kiernan-Linn stated that the platform avoided heavily gamified design elements and maintained trading hours aligned with underlying market conditions for certain assets. According to him, this approach was intended to address issues related to liquidity and funding-rate volatility during periods of lower market activity.

Additional topics included the contracts-for-difference (CFD) market, transparency in blockchain-based trading systems, and Ostium’s operational plans for 2026. ^[10]

Perpetual Contracts and Cross-Asset Trading #02

On April 2, 2026, Kaledora Kiernan-Linn appeared on the 1000x Podcast to discuss Ostium, decentralized finance (DeFi), macroeconomic conditions, and the use of perpetual contracts (“perps”) in cross-asset trading.

During the interview, Kiernan-Linn discussed her background in professional ballet and her later transition into finance and cryptocurrency-related ventures. She stated that aspects of ballet training, including discipline and long-term planning, influenced her approach to business operations. She also referred to the formation of Ostium with co-founder Marco, whom she met while studying economics at Harvard University.

Kiernan-Linn stated that Ostium’s development was influenced by the view that the post-COVID economic environment differed from the period between the 2008 financial crisis and 2020. According to her, the current environment is characterized by higher inflation, fluctuating interest rates, and increased geopolitical uncertainty. She stated that these conditions could contribute to increased interest in event-driven and cross-asset trading strategies.

The interview also addressed Kiernan-Linn’s concept of the “perpification of everything,” a term she used to describe the expansion of perpetual contracts into markets beyond cryptocurrencies, including commodities and equities. According to her, perpetual contracts provide a unified trading instrument across different asset classes and reduce reliance on separate market-specific products.

Kiernan-Linn additionally discussed Ostium’s infrastructure model. She stated that the platform was designed to connect with existing market liquidity rather than operate through a fully independent on-chain exchange structure. According to her description, the model combines blockchain-based settlement systems with external liquidity sources.

The discussion also included comments on the role of online communities, social media platforms, and macroeconomic news in trading activity. Kiernan-Linn stated that rapid information circulation and internet-based market discussions have become part of trading behavior across both cryptocurrency and traditional financial markets. ^[11]
