# Swap

## What is Token Swapping?

Token swapping is the process of exchanging one cryptocurrency for another instantly. On Tapp Exchange, you can trade APT for USDC (or any supported token pair) directly from your wallet without needing to find a trading partner.

**Simple Example:**

* You have: 10 APT tokens
* You want: USDC tokens
* Tapp automatically calculates: 10 APT = \~100 USDC (if APT = $10)
* The swap happens instantly through liquidity pools
