How do I withdraw ETH from Starknet?

If you're looking to withdraw ETH from Starknet, the process can be a bit complex as it involves bridging between Layer 1 (Ethereum mainnet) and Layer 2 (Starknet). Firstly, it's important to understand that Starknet is a decentralized application platform built on top of Ethereum using the StarkWare zk-Rollup technology. Here's a high-level overview of the steps you'll need to take: 1. Identify a suitable bridge: Since Starknet is a Layer 2 solution, you'll need to find a bridge that supports moving ETH from Starknet back to the Ethereum mainnet. There are several bridges available, so research to find one that suits your needs and preferences. 2. Prepare your ETH: Make sure the ETH you want to withdraw is in a compatible wallet that can interact with the bridge. Keep in mind that there may be minimum or maximum withdrawal amounts, so check the bridge's terms and conditions. 3. Initiate the withdrawal: Follow the bridge's instructions to initiate the withdrawal process. This may involve sending a transaction from your Starknet wallet to the bridge's smart contract. 4. Wait for confirmation: Once you've initiated the withdrawal, you'll need to wait for the transaction to be processed and confirmed on both the Starknet and Ethereum networks. This can take some time, depending on network congestion and other factors. 5. Check your mainnet wallet: Once the withdrawal is complete, the ETH should appear in your Ethereum mainnet wallet. It's important to note that there may be fees associated with withdrawing ETH from Starknet, and the fees can vary depending on the bridge you use and the current network conditions. Make sure you understand the fees before initiating the withdrawal process. Keep in mind that the above steps are a general overview, and the specific steps may vary depending on the bridge you use. It's always a good idea to consult the bridge's documentation or customer support for more detailed instructions.
