Base to Arbitrum Route: Base Wallet Guide

Why this matters on Base

Base and Arbitrum are both L2 environments, but that does not make their token contracts interchangeable. Treat the destination token as a network-specific asset.

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.

Base and this route

Base is the starting network for this route. Before moving anything to Arbitrum, confirm which assets you actually hold on Base.

Leaving Base

Consider Base transaction costs together with bridge and route costs when moving small balances. Use trusted interfaces and verify destination network and token before signing.

Arriving on Arbitrum

Confirm the Arbitrum token contract rather than assuming an identical ticker represents the same asset everywhere. Compare L2 transaction costs with any bridge or liquidity costs required to reach the destination.

Base: what to pay attention to

• Costs: Consider Base transaction costs together with bridge and route costs when moving small balances.
• Security: Use trusted interfaces and verify destination network and token before signing.
• Assets and tokens: Verify the token contract on Base and do not rely on ticker or logo alone.

A Base checklist for this topic

• Send a small test amount first if the route or address is new to you.
• Confirm that the token you hold on Base is supported for the route you are reading about.
• Verify the source network, the destination network and the destination address before signing.
• Compare quotes and the minimum received amount, since the final amount can differ from the estimate.

Bridge from Base

Consider Base transaction costs together with bridge and route costs when moving small balances. On the Optimism side: verify the Optimism contract address for the asset you intend to move.

The bridge guide below is informational; any transaction depends on current network conditions and the route shown in the bridge interface.
