Bridging existing funds from Ethereum (Layer 1) to Optimism (Layer 2)
To bridge your existing funds there are several bridges to move between different blockchains. Optimism has a official bridge called Optimism Gateway.
Follow these steps to bridge your Crypto Francs (XCHF) or Ether (ETH).
Step 1: Connect your wallet (for the Aktionariat wallet choose WalletConnect)
Step 2: Approve your XCHF
Step 3: Finally, deposit your XCHF or ETH
That's it! It will take up to 20 minutes until the funds will be visible in your wallet. Alternatively for Ether you can use a fast bridge like Hop.exchange in similar fashion. A guide for Hop can be found here.
