Mar 11, 2026

ETH on Arbitrum is the gas token for the Arbitrum ecosystem and the base asset for its DeFi protocols. Relay lets you acquire ETH on Arbitrum from any supported asset or chain — no account, no KYC, settling in seconds.

What Is ETH on Arbitrum?

Arbitrum One is an Ethereum rollup that inherits Ethereum's security while offering significantly lower gas fees. ETH on Arbitrum is used to:

• Pay gas for Arbitrum transactions (much cheaper than Ethereum mainnet)
• Trade on GMX — Arbitrum's flagship perpetuals exchange
• Provide liquidity on Camelot and Uniswap
• Use as collateral in Arbitrum DeFi protocols

ETH bridges seamlessly between Ethereum mainnet and Arbitrum — it's the same asset, just settled on the rollup.
