zkSync Wallets and the Arbitrum to Base Route

Why this matters on zkSync

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.

zkSync is an Ethereum scaling ecosystem with its own network context and token representations.

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

zkSync and this route

zkSync is neither end of the Arbitrum to Base route, but a wallet that uses zkSync often holds balances on those networks too. If your assets are on zkSync, they would first have to be on Arbitrum for this route to apply.

Leaving Arbitrum

Compare L2 transaction costs with any bridge or liquidity costs required to reach the destination. Verify the network, contract and destination before signing cross-chain transactions.

Arriving on Base

Verify the token contract on Base and do not rely on ticker or logo alone. Consider Base transaction costs together with bridge and route costs when moving small balances.

zkSync: what to pay attention to

• Costs: Compare network fees with bridge and liquidity costs for the complete route.
• Security: Check the active network, contract and destination before signing.
• Assets and tokens: Verify the asset contract on zkSync before assuming it matches another network.

A zkSync checklist for this topic

• Do not assume a route from zkSync is available; check the current interface and quote.
• Send a small test amount first if the route or address is new to you.
• Confirm that the token you hold on zkSync is supported for the route you are reading about.
• Verify the source network, the destination network and the destination address before signing.

Bridge from zkSync

Compare network fees with bridge and liquidity costs for the complete route. On the Linea side: verify the token contract on Linea before moving it.

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