Beta Release: the Uniswap protocol on Optimistic Ethereum is currently in beta release. Before depositing, please read our blog post to evaluate the risks associated with this early-stage network.
You can transfer assets from Layer 1 Ethereum to Layer 2 OΞ through the Optimism Gateway. Deposits will arrive in your wallet within 5 minutes so you can start trading on the Uniswap protocol with low fees right away.

Confirm the transaction in your wallet. Note that this is a Layer 1 transaction so normal gas fees will apply. However, after this one-time deposit you will experience the joy of lower gas fees on OΞ.
Watch your transaction be confirmed by the network within a few minutes.
That’s it! Your funds should be available on OΞ within about five minutes — the time required for your transaction to be confirmed on Layer 1.
Next, connect your wallet to OΞ so you can start trading on the Uniswap protocol!
