In order to make your ETH compatible with Quix or Stratos, you must first "bridge" it from Layer 1 (mainnet) to Layer 2 (Optimism/Arbitrum). We recommend using either Hop Exchange, the Optimism Gateway, or the Arbitrum Bridge to do so. If using Hop, just make sure you have Optimism or Arbitrum selected as the network when you're sending the ETH.
NOTE: Bridging ETH can take up to 20-30 minutes to complete.
