# Depositing into Optimistic Ethereum
OVM 2.0 Release Dates
OVM 2.0 is already released on the Kovan test network. We expect to deploy it to the production Optimistic Ethereum network on November 11th.
# Which Assets?
Optimistic Ethereum transactions require ETH, just as do L1 Ethereum transactions (except a lot less of it). Here are some ways to get your Ether to Optimistic Ethereum.
- The teleporter (opens new window), a custodial gateway that allows you transfer up to 0.05 ETH. It is a cheap gateway, but a custodial one (meaning you trust the people running it to be honest)
- The Optimism Gateway (opens new window), which costs more but allows for larger transfers and uses the same underlying trust mechanisms as Optimistic Ethereum itself.
- Hop (opens new window) which also allows large transfers, but may have a different exchange rate than 1:1.
# ERC-20 Tokens
The Optimism Gateway (opens new window). We have a list of supported ERC-20 tokens (opens new window), but you are not limited to them, you can select any token that exists on both L1 and L2 (opens new window).
Do not attempt to transfer a token that isn't in the user interface unless you are sure of the Optimistic Ethereum address of the equivalent ERC-20 token.
Third-party bridges (opens new window). Those bridges are usually cheaper and faster than our main gateway, but have a more limited list of supported tokens.
# Depositing through the Optimism Gateway
Click CONNECT, select your wallet type, and approve the connection in the wallet itself if asked.
Make sure the form is correct:
Deposit is selected
The asset is the one you wish to deposit.
Set an amount that is available in your account. Click MAX if you want to deposit your entire balance.
Click DEPOSIT again to confirm.
Confirm the transaction in the wallet, wait until the transaction is confirmed and the ETH deposited to Optimistic Ethereum.
Browse here (opens new window) and click connect to add the Optimistic Ethereum network to your wallet. You will need to approve this addition in your wallet. The network notification in MetaMask is shown below, other wallets are likely to be similar
