Unifold

Unifold is here to make crypto deposits so stupidly easy that your grandma could do it—and honestly, she probably could. Founded in 2024 and backed by Y Combinator, Unifold built a single API that handles deposits across Ethereum, Solana, Bitcoin, and basically every chain that matters. Any token, any chain, any stablecoin. One integration. That's it.

The problem? Crypto payments are still a mess. Users need gas tokens, they need to bridge between networks, they need to figure out which exchange to use, and half the time they give up because the whole process takes 47 steps and three business days. Unifold fixes this by handling routing, settlement, gas sponsorship, and compliance in one clean stack. They integrate with major centralized exchanges like Coinbase and Gemini so users can deposit without the traditional KYC nightmare—and compliance stays on-chain where it belongs. Developers can drop in their SDK and launch a full deposit flow in under 9 minutes. Yes, nine.

They're targeting consumer apps and fintech companies that want to add crypto payments without building an entire infrastructure team. Unifold provisions dedicated deposit addresses per user automatically, routes deposits based on liquidity and fees, and sponsors every transaction so end users never need to hold gas tokens. This is the "one API to rule them all" play for crypto payments—and with Y Combinator behind them, they're positioned to become the Stripe of on-chain deposits.
