Know what drove your returns. Deterministic, no-LLM portfolio attribution: send position start/end values, dated cash flows, and a reporting period; get Modified Dietz and XIRR returns, alpha against BTC, ETH, stETH, or a benchmark you supply prices for, plus per-position contribution. Caller-declared data-quality flags, a calculation hash, and an optional EIP-191 signature support transparent reporting and verification for fund managers, DAO treasuries, and their LPs.
