Unifold
Unifold is a developer-first API and SDK that lets any app accept on-chain deposits across any blockchain and token in under 10 lines of code. It handles the full deposit flow - cross-chain routing, gas abstraction, compliance checks, and settlement - so users never have to think about chain IDs, bridging, or which version of USDC to use. Founded in 2026 by a team that previously built wallet infrastructure onboarding 30M+ users to apps like Phantom and Polymarket, Unifold is a Y Combinator Winter 2026 company based in New York City.
