Private jets are paying for fuel mid-flight in stablecoins. Watch dealers are settling five-figure deals the same way. And credit cards can't keep up with either.
Will Harborne joined crypto in 2016, working at Tether back when the word "stablecoin" barely existed yet. He co-founded Ethfinex in 2017, one of the earliest Ethereum-based decentralized exchanges, which evolved through several rebrands (DeversiFi, then Rhino.fi) as the company grew from a retail cross-chain bridge that processed billions in volume and onboarded over two million users, into its current focus as B2B stablecoin infrastructure for fintechs and neobanks.
Now Rhino.fi's "stablecoin activation stack" lets businesses like Wirex, Plasma One, and a growing list of neobanks send and receive stablecoins across 35+ blockchains in under ten seconds, abstracting away the chain and token complexity entirely. Will sits down with Boaz Sobrado to talk about why time-critical, high-value payments are quietly exploding, why crypto's idealists feel betrayed by its own success, and what happens now that Wall Street's biggest fintechs are eating DeFi's lunch.
