Summary: The best way to bridge to the StarkNet zk-rollup layer 2 network is with a trusted cross-chain DEX. We recommend Orbiter Finance, which allows users to transfer funds from Ethereum, Arbitrum, Optimism and Polygon to StarkNet for low fees.
Can I Bridge from Optimism to StarkNet?
Yes, you can bridge to StarkNet, a prominent zk-based Layer-2 solution on the Ethereum network. This process generally entails transferring your assets (e.g., ETH or USDT) from Ethereum or another Layer 2 to StarkNet via a trusted cross-chain bridge.
In this process, your assets get locked in a smart contract on the sending network (e.g Ethereum) to avert a double spend. Following this, the locked assets are swiftly issued to you on the StarkNet network, guaranteeing a seamless transition between the two platforms.
How to Bridge to StarkNet
If you are looking to bridge to the StarkNet Layer 2, you will need to use a zk-rollup bridge that enables cross-chain swaps between EVM networks and zk-based blockchains. We recommend Orbiter Finance because they are compatible with most EVM networks and offer transfers with ETH, USDC and USDT tokens.
To get started, you will need to follow these 5 simple steps:
- Download and install the ArgentX Wallet (the only wallet compatible with StarkNet).
- Visit Orbiter Finance and connect your ArgentX Wallet.
- Select the network you want to transfer tokens from.
- Select the tokens you want to transfer and the amount.
- Review and confirm the transfer. Wait 5 minutes and the tokens will arrive on StarkNet.
StarkNet Bridging Fees
The fees to bridge to the StarkNet ecosystem will vary depending on the network you are transferring assets from. For example, if you are bridging from Ethereum you will pay slightly higher fees which average at around $20-$30. This is because transactions on mainnet are generally more expensive due to higher demand for blockspace.
On the other hand, if you are bridging from other Layer 2 ecosystems like Polygon, Arbitrum, Optimism, METIS and others - the transaction should not exceed $10.
Is Orbiter Finance a Safe StarkNet Bridge?
Orbiter Finance is one of the safest and most trusted bridge for all zk-rollup layer 2 networks. They currently support interoperability features for StarkNet, zkSync, DYDX, Loopring and other popular zk-based layer 2's. We recommend that users stick with this platform when transferring assets to StarkNet.
Final Thoughts
In conclusion, StarkNet provides an efficient and cost-effective zk-rollup Layer-2 solution for Ethereum users, with Orbiter Finance standing as a trusted, interoperable bridge service to transfer assets from Ethereum and other Layer-2 networks. The process is straightforward, requiring a transfer of assets via a smart contract to prevent double-spending, all while keeping transaction fees within reasonable limits.
It is crucial to use a compatible wallet, like ArgentX, to facilitate these transfers. Regardless of the network you're bridging from, Orbiter Finance has proven to be safe and reliable, offering comprehensive support for a wide array of popular zk-based layer 2 networks.
