Y Combinator, the Silicon Valley startup incubator behind Airbnb, Coinbase and Stripe, is collaborating with Base and Coinbase Ventures to create the next wave of so-called “Fintech 3.0” companies, according to a blog post on Tuesday. A prime example of this is Base, the Ethereum overlay blockchain attached to Coinbase which recently partnered with Shopify to offer global USDC payments. “Our mission at Base is to build a global economy that increases innovation, creativity, and freedom. To do this, we need more founders to build on-chain businesses so that anyone, anywhere can participate in the global economy,” the blog post said. The initiative comes as U.S. lawmakers move to clarify rules for crypto.
