# IAP On-chain

*Native crypto payments for in-game assets*

Cozy World features a fully onchain **In-App Purchase (IAP)** system that allows players to seamlessly buy and sell in-game assets using **SEI** and **USDC** , both native to the Sei Network.

From cosmetic items to gameplay boosters and utility assets, all purchases are:

* **Instant** via fast finality on Sei
* **Transparent** and verifiable onchain
* **Integrated** with Cozy Backpack and Autonomous for automated use

This native IAP infrastructure ensures that every transaction enhances ownership, composability, and interoperability within the Cozy ecosystem.

> No bridges, no middlemen - just pure onchain ownership.
