SoFi Wants to Be the Stablecoin Liquidity Hub for Banks | Ben Reynolds

In this episode of Talking Tokens, Jacquelyn Melinek speaks with Ben Reynolds, SVP and head of Big Business Banking at SoFi, about why the company launched its SoFi USD stablecoin on Solana and what it means for the firm’s broader vision to become a stablecoin liquidity hub. Ben, who joined Silvergate in 2016 and helped build the Silvergate Exchange Network before the bank shut down in 2023, explains how commercial banks are finally building in the space now that the regulatory environment has changed under the current administration. He walks through why SoFiUSD reserves are held in a Fed master account with zero credit, liquidity, or duration risk and why stablecoin infrastructure is still far less mature than people think. He also explains how the next catalyst for onchain payments could come top down from banks with built-in network effects rather than bottoms up from crypto companies. The conversation covers why non-dollar stablecoins at scale would transform cross-border payments, how SoFi's 15 million users and card processing business create unique synergies, and why building stablecoin-agnostic infrastructure is the smartest strategy right now. This episode is a part of the Solana Sessions campaign that Token Relations and the Talking Tokens podcast are doing, diving into founders' journeys and startups building on Solana.

The 4 Things That Need to Happen Before AI Agents Can Actually Spend Money | An Agentic Payments Explainer

On our first episode of Strata Research presented by Talking Tokens & Token Relations, Jacquelyn sits down with Institutional Research Analyst Alex Beaudry to breakdown agentic payments. Alex walks through why it isn't one market but three distinct payment flows, each with completely different infrastructure requirements, and why the machine-to-machine category is where stablecoins have a real structural edge over traditional rails. They also get into the four things that actually need to happen before this market scales, and why the narrative is still running well ahead of the transaction volumes to back it up.

USDT0's Co-Founder on Moving $90B Cross-Chain, the Agent Economy, and Tether's Untouchable Moat

On today's Talking Tokens, Jacquelyn sits down with Lorenzo Romagnoli, co-founder of USDT0, a stablecoin protocol that has moved over $90 billion in USDT across 25+ blockchains since launching in January 2025. Lorenzo makes the case that stablecoins were not just built for Americans or Europeans but for people in emerging markets across Africa, Latin America, and Asia who needed a way out of crushing inflation, and explains why that's the core reason Tether's dominance is so hard to compete with. They also get into what it will actually take for AI agents to transact onchain at scale, and why Lorenzo believes the teams still building with true decentralization in mind are the ones worth watching.

What You Need To Know About x402 And How It Impacts Payments | Erik Reppel

In this episode of Talking Tokens, Jacquelyn Melinek speaks with Erik Reppel, head of engineering at Coinbase Developer Platform and creator of x402., They discuss why the internet struggled without a native payment protocol and why AI agents finally made the problem urgent enough to solve. Erik explains how x402 lets computers send money as easily as they send data, and why Visa, Mastercard, and others are all founding members of its x402 Foundation. He walks through why the 402 HTTP status code was reserved for "payment required" but left empty for decades, how publishers can now charge AI agents with micropayments instead of losing traffic to scraping, and why agents with wallets are fundamentally more useful than agents without them. The conversation covers why stablecoins are uniquely suited for low-dollar transactions, how Coinbase uses AI internally to make every engineer 3x more productive, and why the best infrastructure eventually becomes invisible.
