zkSync Wallets and the Optimism to Base Route
How zkSync balances relate to the Optimism to Base route.
Why this matters on zkSync
Optimism-to-Base transfers are another example where similar L2 terminology does not remove the need to verify the destination chain and token contract.
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 Optimism 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 Optimism for this route to apply.
Leaving Optimism
Compare network gas with bridge and route costs, especially for low-value balances. Check network, recipient, contract and transaction details before signing.
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
- 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.
- Compare quotes and the minimum received amount, since the final amount can differ from the estimate.
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.
