Y Combinator, Base and Coinbase Ventures Unveil ‘Fintech 3.0’ to Back On-Chain Finance Startups

Applications opened for startups, reflecting a bet that regulatory clarity with mature L2 rails makes on-chain finance ready.

Overview

  • Applications are now open for the Fintech 3.0 initiative, a coordinated accelerator and funding push to build financial systems on blockchain infrastructure.
  • The program prioritizes local-currency stablecoins, tokenization of traditional assets such as stocks and credit, and consumer-facing products including AI financial agents.
  • Organizers point to the GENIUS Act’s federal stablecoin framework as a key enabler, with reporting citing roughly $30 billion in market-cap growth since passage.
  • Base cites sub-second, sub-cent transactions alongside nearly $15 billion in platform assets and over $4 billion in stablecoin value across its network.
  • Recent activity used as proof of traction includes JPMorgan’s USD deposit tokens on Base via Kinexys, Base’s Clanker AI agent generating about $13 million in five months, and a Shopify integration enabling global USDC payments.
