## What ARB-USD is (brief)

ARB-USD is Arbitrum's native token, priced against the US dollar (the "-USD" suffix is the quote currency of the pair, not part of the coin's name) [[21]](https://coinmarketcap.com/currencies/arbitrum/)[[25]](https://99bitcoins.com/cryptocurrency/what-is-arbitrum/). Arbitrum is an Ethereum Layer-2 scaling network using optimistic rollups, developed by Offchain Labs (co-founded by Ed Felten, Steven Goldfeder, and Harry Kalodner) [[21]](https://coinmarketcap.com/currencies/arbitrum/)[[25]](https://99bitcoins.com/cryptocurrency/what-is-arbitrum/). ARB functions primarily as a **governance token** and is **not** used to pay gas fees (those are paid in ETH) [[21]](https://coinmarketcap.com/currencies/arbitrum/)[[25]](https://99bitcoins.com/cryptocurrency/what-is-arbitrum/). Total supply is fixed at 10 billion tokens [[21]](https://coinmarketcap.com/currencies/arbitrum/)[[15]](https://www.vestream.io/resources/arbitrum-arb-token-unlock-schedule). It is a crypto/digital asset, not a security — no company filings, earnings, or share fundamentals apply.
