Bridge zkSync to Starknet
Network differences, fees and safety checks before a zkSync to Starknet transfer.
To bridge from zkSync to Starknet, select both networks in a route aggregator, compare the final received amount across routes, keep native zkSync gas available and confirm the destination address before signing.
zkSync and Starknet have separate network contexts. A cross-chain route must account for the source environment, destination environment and the mechanism used to transfer or represent the asset.
Route Intelligence
zkSync: zkSync is an Ethereum scaling ecosystem with its own network context and token representations.
Starknet: Starknet uses its own account and smart-contract environment, which differs from standard EVM networks.
On the source side, Verify the asset contract on zkSync before assuming it matches another network. On the destination side, Verify Starknet-specific asset and account details.
Compare network fees with bridge and liquidity costs for the complete route. On Starknet, Check the current network cost and route mechanics before moving small balances.
Before You Bridge
- Source: confirm the asset is actually held on zkSync.
- Destination: confirm the wallet and destination network.
- Token: verify the exact asset representation rather than relying on ticker or logo.
- Costs: compare gas, bridge fees, liquidity, price impact and the final received amount.
- Security: Check the active network, contract and destination before signing. At the destination, Do not assume EVM contract and wallet conventions apply directly.
Frequently Asked Questions
How do I bridge from zkSync to Starknet?
Choose zkSync as the source and Starknet as the destination in a bridge or route aggregator, pick the token and amount, review the quote and the minimum received amount, then confirm in your wallet. Keep some zkSync native token to pay the fee.
How much does it cost to bridge zkSync to Starknet?
The cost combines the zkSync network fee, the route or bridge fee and any price impact. It changes with network conditions, so use the live quote and compare the final received amount, not just the headline fee.
Is bridging zkSync to Starknet safe?
Bridges add risk beyond a normal transfer. Use a trusted interface, verify the destination network and recipient address, start with a small test amount for new routes and never share a seed phrase.
Use the Live Bridge Tool
When a live route is available, open Dust Sweeper and review the current quote immediately before signing. Route availability, liquidity and network conditions can change.
