# Overview

# ONEgametoken

**ONEgametoken ("Gametoken")** is a non-custodial marketplace for **game tokens** on ONE Chain. Each partner game issues its in-game currency as an on-chain token, and Gametoken brings these tokens together in one place where you can:

* **Swap** any game token for **ONEUSD**, instantly and on-chain.
* **Provide liquidity** to a token's pool and earn a share of trading fees.
* **Track** your holdings and full transaction history across every market.

## How it works at a glance

| Layer           | What it is                                                                                                                                                                       |
| --------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **ONEUSD**      | The ecosystem's default settlement currency and the common asset that every game token trades against. Prices and volume are quoted in ONEUSD.                                   |
| **$ONE**        | The native coin of ONE Chain, used for network gas.                                                                                                                              |
| **Game Tokens** | On-chain tokens issued by partner games, representing their in-game currencies and assets.                                                                                       |
| **Forge**       | The on-chain market engine that holds each game token's liquidity pool (paired with ONEUSD, using virtual reserves) and executes every swap. See [ONE Forge](/docs/cross-forge). |

> Gametoken is **not** an order book. Prices are set by Forge's on-chain liquidity pools, so there are no limit orders and no counterparty to wait for. Every swap settles immediately against a pool.

## Non-custodial by design

All features operate on a **non-custodial** basis through on-chain smart contracts. **Nexus never takes custody of your funds.** Every swap and liquidity action runs only after **you sign the transaction** with your own wallet, and all activity is verifiable on the public block explorer.

> **Gas is on us.** Network gas for swaps and liquidity actions is **sponsored by the service**, so you don't need to hold extra $ONE for gas. Token transfers (Send) are the one exception. See [Fees & Gas](/docs/trading-fee).
