**Virtual currency** is any digital medium of exchange used within or across online platforms—encompassing in-game currencies, platform tokens, [cryptocurrencies](https://metavert.io/cryptocurrency), and stablecoins.

Virtual currencies power the largest digital economies on Earth. Roblox's Robux, Fortnite's V-Bucks, and other in-game currencies collectively process tens of billions of dollars in annual transactions. These closed-loop currencies function as the monetary infrastructure for [virtual economies](https://metavert.io/virtual-economy) where millions of creators earn real income: Roblox paid over $740 million to developers in 2024 through Robux conversion.

[Cryptocurrencies](https://metavert.io/cryptocurrency) introduced open, [permissionless](https://metavert.io/permissionless) virtual currencies that operate outside platform boundaries. Bitcoin functions as a digital store of value. Stablecoins (USDC, USDT, DAI) pegged to fiat currencies have crossed $310 billion in circulation and now process more annual transaction volume than Visa—making them the most commercially successful virtual currency innovation. Central Bank Digital Currencies (CBDCs) represent government-issued virtual currencies, with China's digital yuan in active use and the EU's digital euro in development.

The trajectory points toward increasing interoperability between previously siloed virtual currencies. [Blockchain](https://metavert.io/blockchain)-based bridges and Layer-2 networks enable cross-chain value transfer. Some game platforms are experimenting with [Web3](https://metavert.io/web3) integration that lets players move value between games. As [AI agents](https://metavert.io/agentic-ai) increasingly transact on behalf of humans—purchasing services, paying for compute, tipping content creators—virtual currencies become the native payment rail for the [agentic web](https://metavert.io/agentic-web), where microtransactions happen at machine speed.
