# Welcome to Caesar

Caesar is a crypto tax rail that turns crypto transaction data into tax-ready outputs. Built as API-first infrastructure with a rules-as-data architecture that handles crypto tax calculations so you don't have to. If you run a crypto platform (an exchange, wallet, payment gateway, or trading app), Caesar takes care of the complicated tax stuff for both you and your users.

**What Caesar does for you:**

* ✅ Calculates capital gains when users sell crypto
* ✅ Tracks income tax on crypto rewards and earnings
* ✅ Handles VAT (7.5%) on your platform fees
* ✅ Manages WHT (Withholding Tax) on payouts
* ✅ Generates FIRS-compliant tax reports

**What you need to do:**

* Send us user information (name, NIN/RC number)
* Send us transaction data (buys, sells, trades, etc.)
* That's it! We handle the rest.
