zkSync Wallets and the Ethereum to Polygon Route

Why this matters on zkSync

Ethereum-to-Polygon transfers require attention to token representation and source gas. A route can be technically valid while still being uneconomical for a very small balance.

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 Ethereum to Polygon 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 Ethereum for this route to apply.

Leaving Ethereum

Ethereum gas can make very small balance movements uneconomical, so compare total execution cost with the balance value. Pay close attention to contract approvals, transaction details and the exact domain used to initiate a transaction.

Arriving on Polygon

Confirm that the token is held on Polygon and verify its contract before moving or swapping it. Compare Polygon transaction costs with bridge and liquidity costs when consolidating 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

• 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.
• Keep enough native balance on the source network to pay for the transaction.

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.
