# Other

This report focuses on cryptocurrencies that are primarily used as a form of payment or, in the case of smart contract platforms, to run a payment network. 

That said, while virtually all cryptocurrencies can be used as a form of money, many were designed primarily for other means, including tokens that are used to:

* Run DeFi protocols (e.g. Uniswap and Aave)
* Power decentralized oracle networks (e.g. Chainlink)
* Serve as gaming tokens (e.g. Axie Infinity)
* Provide currency for virtual worlds (e.g. Decentraland and Sandboxx)
* Assist with DAO governance (e.g. ApeCoin)
* Enable key web3 infrastructure (e.g. Arweave, Filecoin, Helium, Pocket Network, The Graph) 
* Assist with interoperability (e.g. Thorchain)

Since there are tens of thousands of cryptocurrencies, we won’t focus on these here, but they will be covered in detail in other reports.
