What ETH is
ETH is the gas coin on Arbitrum One. Every transaction on the network pays its fee in ETH, not in ARB, which is a governance token and pays for nothing. It is the same asset as ether on Ethereum but a separate balance: ETH on Arbitrum stays on Arbitrum until it is bridged elsewhere.
A swap on Arbitrum usually costs a few cents in ETH, so a small amount covers many transactions. Its price is ether's price, moved by demand for Ethereum, staking, fund flows and the market as a whole.
In apps it appears as WETH, a contract that holds ETH one-for-one. The chart here is drawn from WETH's deepest pool on Arbitrum, against USDC.
