Arbitrum to Base Route: Arbitrum Wallet Guide

Why this matters on Arbitrum

Moving between Arbitrum and Base can be straightforward when a supported route exists, but route availability and costs can change. Check the live quote immediately before execution.

Arbitrum is an Ethereum Layer 2 environment with its own balances and application ecosystem.

Arbitrum is part of the Ethereum scaling ecosystem. The same ticker can exist on Ethereum and on Arbitrum as separate token contracts, so a balance seen on one network cannot be assumed to exist, or to be redeemable at the same value, on the other.

Arbitrum and this route

Leaving Arbitrum
