# Exponential

**Canonical:** https://apis.io/providers/exponential/  
**Website:** https://exponential.fi  
**APIs profiled:** 2

Exponential.fi is a DeFi company (backed by Paradigm and Norwest Venture Partners) behind YO Protocol — a cross-chain "Yield Optimizer" that automatically allocates deposits across the best-performing liquidity pools on multiple blockchains to deliver the highest risk-adjusted yield, using Exponential.fi's own Risk Ratings to balance risk and reward. yoVaults are ERC-4626 tokenized vaults (yoUSD, yoETH, yoBTC, yoEUR, yoGOLD, yoSOL and more) with ERC-7540-style async redemption, all routed through the single yoGateway entry point. The developer surface spans a public read API (api.yo.xyz), a first-party TypeScript SDK/React kit/CLI (@yo-protocol/*), official agent skills and a Base MCP plugin, and the YO Risk Graph — a paid, agent-facing DeFi risk-intelligence API monetized per-call via the x402 USDC micropayment standard on Base.
