Why Is Robinhood Building on Arbitrum | AJ Warner
On today’s Talking Tokens episode, Jacquelyn sits down with AJ Warner, Director of Strategy at Offchain Labs, the team behind Arbitrum, one of Ethereum’s top layer-2 blockchains with over $4B in TVL.
AJ shares his journey from real estate lawyer to crypto strategist, and how a college connection led him to help build Arbitrum from the ground up. They discuss the unique "barbell" strategy powering both Arbitrum One and Arbitrum Orbit, why liquidity and composability are critical for growth, and how Arbitrum balances being a top public chain with enabling enterprises to launch custom blockchains. He also dives into the recent Robinhood partnership - from launching tokenized stocks on Arbitrum One to designing a dedicated Robinhood chain - and why powering fintech products with crypto rails might be the fastest path to mass adoption. Plus, AJ breaks down why some projects shouldn’t launch their own chain, how Arbitrum’s governance gives token holders real control over upgrades and revenue, and where L2 innovation is headed next.

Is OUSD Really Just Stripe's Stablecoin? | Alex Beaudry, Strata Research
On this edition of Strata Research, Jacquelyn sits down with our Institutional Research Analyst Alex Beaudry to dig into the OUSD announcement that resulted in Circle's stock dropping and had the crypto world convinced a new stablecoin competitor had arrived. After looking into the details, Alex argues this is just Stripe's stablecoin wrapped in a consortium for competitive cover, then he walks through why the 140 company list is largely a marketing move before getting into which of the two paths to success for OUSD he actually thinks will play out.
