+1.  The "currency symbol" is required by some wallets like MetaMask.
+2.  The `OptimismPortal` is a low-level contract responsible for passing messages between L1 and L2. You can send `ETH` directly to the portal to receive it to the sender address on the L2.
+
+## Bridging ETH to the Release Candidate - Alpha devnet
+
+<Steps>
+  ### Get Sepolia ETH from the Superchain Faucet
+
+  You can utilize the [Superchain Faucet](https://console.optimism.io/faucet) to get `ETH` on Sepolia.
+
+  ### Send the Sepolia ETH to the devnet
+
+  You can send `ETH` directly to the `OptimismPortal` address and it will go to the same sender address on the devnet.
+
+  ### Wait for bridging to complete
+
+  It'll take approximately 2 minutes for the bridging process from Sepolia to L2 to complete and the `ETH` to appear in your wallet.
+</Steps>
