Arbitrum to Base Route: Base Wallet Guide

Why this matters on Base

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.

Base is an Ethereum Layer 2 environment with its own network balances, applications and token representations.

Base is part of the Ethereum scaling ecosystem. The same ticker can exist on Ethereum and on Base 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.
