 The ETH bridging process is generally less complex than the ERC-20 bridging process.
 Users simply need to trigger and send ETH to the [`bridgeETH`](https://github.com/ethereum-optimism/optimism/blob/2e647210882d961f04055e656590d90ad98c9934/packages/contracts-bedrock/src/universal/StandardBridge.sol#L143-L150) or [`bridgeETHTo`](https://github.com/ethereum-optimism/optimism/blob/2e647210882d961f04055e656590d90ad98c9934/packages/contracts-bedrock/src/universal/StandardBridge.sol#L152-L166) functions on either blockchain.

+    Users can also deposit ETH from Ethereum to OP Mainnet by sending a basic ETH transfer from an EOA to the `L1StandardBridgeProxy`. 
+    This works because the `L1StandardBridgeProxy` contains a [`receive`](https://github.com/ethereum-optimism/optimism/blob/2e647210882d961f04055e656590d90ad98c9934/packages/contracts-bedrock/src/universal/StandardBridge.sol#L119-L121) function.
+    You can find the mainnet and testnet addresses on the [Contract Addresses](/chain/addresses) page.
