The useful limits

01 / SIMPLE MATH

Yield is an input, not a forecast.

This tool applies principal × annual rate × years. It does not predict price, liquidity, platform risk, taxes, or compounding.

02 / RISK CHECK

A bigger percentage can mean a bigger question.

Treat eye-catching yields as a prompt to investigate lockups, counterparties, token mechanics, and how returns are actually funded.
