Bridge Ethereum to Starknet
Network differences, fees and safety checks before a Ethereum to Starknet transfer.
To bridge from Ethereum to Starknet, select both networks in a route aggregator, compare the final received amount across routes, keep native Ethereum gas available and confirm the destination address before signing.
Ethereum 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
Ethereum: Ethereum is an EVM network and the base layer for a large ecosystem of tokens, applications and Layer 2 networks.
Starknet: Starknet uses its own account and smart-contract environment, which differs from standard EVM networks.
On the source side, Verify the ERC-20 contract address and distinguish Ethereum-native assets from representations on other networks. On the destination side, Verify Starknet-specific asset and account details.
Ethereum gas can make very small balance movements uneconomical, so compare total execution cost with the balance value. 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 Ethereum.
- 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: Pay close attention to contract approvals, transaction details and the exact domain used to initiate a transaction. At the destination, Do not assume EVM contract and wallet conventions apply directly.
Frequently Asked Questions
How do I bridge from Ethereum to Starknet?
Choose Ethereum 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 Ethereum native token to pay the fee.
How much does it cost to bridge Ethereum to Starknet?
The cost combines the Ethereum 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 Ethereum 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.
