FTM is a proof-of-stake (PoS) token which in fact exists in several incarnations.
The platform’s compatibility with Ethereum means that users can purchase an [ERC-20](https://coinmarketcap.com/alexandria/glossary/erc-20) standard FTM, which is automatically converted to native FTM once received to their wallet. Another version of FTM is available on Binance Chain using its BEP2 standard. Only the native FTM can be used on the Fantom OPERA mainnet itself.
The total supply of FTM is 3.175 billion tokens, of which 2,134,638,448 FTM is currently in circulation. The rest will be released subject to a schedule running through 2023.
Staking forms an important part of tokenomics, with a proportion of the supply reserved specifically for staking rewards to users who hold FTM.
