Temporal, a research and development firm best known for architecting the Harmonic blockbuilding client and operating Humidifi, one of Solana’s leading prop AMMs, is preparing to scale.
Bringing a wealth of experience across onchain trading, corporate strategy, and M&A, Marcantonio is confident Temporal has the technical pedigree to supplant household names like Goldman Sachs, JP Morgan, and Morgan Stanley and “reengineer the global financial system”.
Michael Marcantonio to Spearhead Temporal’s Evolution
After a 5-year tenure at Galaxy Digital, serving as the firm’s Head of DeFi and previously as Senior Corporate Counsel, Michael Marcantonio has been appointed as Temporal’s new CEO.
Having led Galaxy Digital’s onchain trading and DeFi business strategy and helped the firm become one of the crypto industry’s most prolific names, Marcantonio now brings his experience to one of Solana’s most talented technical teams.
“Pound for pound, Temporal has the most technically gifted team of engineers and quant traders on Solana, the most performant decentralized blockchain in the world. This team is at the bleeding edge of redesigning market structures that have existed for more than a century. They started by revolutionizing spot trading on Solana and are now poised to do the same for fully decentralized, onchain perpetual futures, prediction markets, options, and structured products. With a team of this caliber, I have no doubt we will build the next generation of decentralized financial systems that will warehouse trillions of dollars in global capital.” - Michael Marcantonio, Temporal CEO
Beyond scaling Temporal’s existing offerings, Marcantonio is expected to guide the rollout and development of a new range of products designed to reshape global markets onchain. As crypto’s most performant blockchain, Solana represents the most fertile ground for this type of financial onchain experimentation.
Throughout 2025 and 2026, Solana has consistently led all chains in spot trading volume and application revenue. Much of this outperformance comes from the network’s inherently superior market microstructure, through which prop AMMs, like Temporal’s own venue, HumidiFi, consistently outperform centralized exchanges on trade execution.
As a result, Solana routinely processes higher daily trading volume than leading exchanges, like Coinbase, Bybit, and Kraken.
Outside of trading alone, Solana has reasserted its position as the leading venue for tokenized stock trading. After dominating tokenized equity markets since mid 2025, Solana has shrugged off recent challenges from rival networks like BNB Chain and Robinhood, capturing over 34% of market share.
As one the teams contributing to both blockbuilding infrastructure and onchain market making, Temporal is likely to continue playing a key role in Solana’s ongoing success. With the lines dividing TradFi and DeFi starting to blur, the years ahead will likely be some of the most competitive in crypto’s history.
Between closed-door, corporate chains like Canton joining the race for onchain supremacy, and household names like ICE, the parent company behind the New York Stock Exchange, venturing into 24/7 trading, true decentralization has never been more critical to the DeFi ethos. Marcantonio argues that Temporal can help Solana go head-to-head against the giants of yesteryear, enabling a truly open and competitive onchain economy.
“Our ambition is to reengineer the global financial system. We are taking on Goldman Sachs, JPMorgan, and Morgan Stanley, and the legacy financial order they represent. We reject a system in which a handful of institutions exert unprecedented control over access to capital, capture all of the upside, and hand the public the bill when their bets go wrong. We speak for a generation that has been systematically excluded from opportunities in the traditional financial economy, yet repeatedly expected to bear the cost of its failures. That generation has been promised reform countless times. It has never come. We’re done waiting. Temporal’s mission is not to reform a broken financial system, but to replace it.” - Michael Marcantonio, Temporal CEO
Temporal to Step Beyond Blockbuilding, Quantitative Trading, and Staking?
Having already developed one of Solana’s leading prop AMMs, and a blockbuilding client running on 31% of network stake, Marcantonio has hinted that Temporal could be expanding its product line into “onchain perpetual futures, prediction markets, options, and structured products”.
These statements are consistent with claims made earlier this year by Temporal founder Ben Coverston, who has long argued against the widely-held belief that Solana was ill-equipped to house a competitive perps venue.
Beyond customer-facing applications, Temporal engineers have also been front-and-center of recent governance proposals designed to channel onchain activity into $SOL value accrual. While SGP-003 was ultimately rejected by Solana’s voters, Marcantonio’s appointment could see Temporal revisit its attempts to implement programmatic value accrual to $SOL.
