## Capabilities & Context
YieldCircle is an **institutional-grade intelligence, DeFi execution, and infrastructure layer for AI Agents.** It provides quantitative alpha from 10 years of financial history, autonomous DeFi execution across 15+ chains via Enso Finance, cross-chain bridging via Across Protocol, and secure Privy TEE-signed wallets — all through a single API.
