Bridge Polygon to Starknet
Network differences, fees and safety checks before a Polygon to Starknet transfer.
To bridge from Polygon to Starknet, select both networks in a route aggregator, compare the final received amount across routes, keep native Polygon gas available and confirm the destination address before signing.
Polygon 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
Polygon: Polygon provides an EVM-compatible environment with its own network balances and token representations.
Starknet: Starknet uses its own account and smart-contract environment, which differs from standard EVM networks.
On the source side, Confirm that the token is held on Polygon and verify its contract before moving or swapping it. On the destination side, Verify Starknet-specific asset and account details.
Compare Polygon transaction costs with bridge and liquidity costs when consolidating small balances. 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 Polygon.
- 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 network selection and contract addresses before signing, especially when an asset also exists on Ethereum. At the destination, Do not assume EVM contract and wallet conventions apply directly.
Frequently Asked Questions
How do I bridge from Polygon to Starknet?
Choose Polygon 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 Polygon native token to pay the fee.
How much does it cost to bridge Polygon to Starknet?
The cost combines the Polygon 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 Polygon 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.
