Arbitrum is an Ethereum Layer 2 ecosystem. A cross-chain route to Arbitrum depends on the source network, token, liquidity and available bridge infrastructure.
Users may need to move assets between Arbitrum and other Layer 2 networks such as Base or Optimism. The live quote determines whether a route is available for the selected asset.
Stablecoins such as USDC and USDT are common cross-chain assets, but the exact token representation and destination network should always be checked before signing.
Confirm the source, destination, token, amount, fees and estimated output shown in the live bridge interface. Route conditions can change quickly as liquidity and gas conditions change.
