OPTIMISM ETHEREUM HOW TO

How to use Uniswap on Optimismīy now you’ve connected your MetaMask to the Optimistic Ethereum network and bridged over the asset of your choice – well done! The final step is to make a trade and see for yourself how fast and economical L2 networks can be. When the bridge is complete, you will see the funds on Optimism and you will have the option to withdraw:īut let’s keep going! And use the ETH we’ve bridged to trade (swap) on Uniswap, a decentralized protocol for trading crypto. Once confirmed, you can monitor the transaction with the Etherscan address provided, as well as follow the number of confirmations shown processing. Then a MetaMask prompt to confirm and start the bridging process will appear. Go to the Optimism gateway and choose the amount of ETH (or the asset of your choice that’s available) as you’d like:Ĭlick “Deposit” when you’re ready. Now that your MetaMask is connected to the Optimism network, let’s send some ETH over. Once you hit save, you’ll be automatically connected to the network and ready to bridge your assets! You can find the many different dapps and protocols on Optimism here.Īnd to see how Optimism works in action, these next sections will show you how to bridge and then how to use optimistic rollups on Uniswap. Now input the Optimistic Ethereum network connection details here and shown below: Next, click the Custom RPC button at the bottom of the network list: Open the MetaMask browser extension, then select the network name at the top: Once that’s done, you can manually add the Optimistic Ethereum network to your wallet in three simple steps: MetaMask is your portal to Web3 that you can use directly in your browser extension.Īlways practice strong security with your seed phrase by ensuring its stored safely in multiple places and never (ever) give it to anyone. Connecting your MetaMask to the Optimism L2 Networkįirst things first: make sure your funds are available in your wallet. Pretty handy, right? Ready to give optimistic rollups a try? Optimistic rollups are distinct from zero knowledge (ZK) rollups, because they use a different method of verification: while ZK rollups rely on each batch of transactions to have their own ‘validity proof,’ optimistic rollups assume all transactions are valid. You can think of optimistic rollups as a smart contract that bundles (or “rolls up”) transaction data and moves it off chain for faster processing. Optimistic Ethereum is an EVM compatible rollup chain designed to be fast, simple, and secure, and allows users to interact with any Ethereum application at a fraction of the cost by using optimistic rollups. Like other L2 solutions, the Optimism team saw an opportunity to be a new scaling solution for Ethereum without compromising security and decentralization as shown in the trilemma. Layer 2 networks, also referred to as bridging solutions, were created to overcome these obstacles and have been extremely effective to sustain growth of the Ethereum ecosystem in spite of barriers like gas fees.

This trilemma has become a classic throughout the blockchain industry, since it so effectively captures the three fundamental obstacles blockchain networks must solve for optimal functionality: scalability, security, and decentralization. In a previous blog about how to bridge your assets to Polygon using MetaMask, we introduced the blockchain scalability trilemma. You’ll learn how to send your assets to the Optimistic Ethereum bridge and trade with low fees and near-instant finality on Uniswap, a decentralized token exchange. In this blog we focus on a popular L2 solution, Optimistic Ethereum. Doing so provides lower transaction fees, higher throughput, better user experience, and sometimes access to dapps not on Mainnet. One of the most efficient ways to get the most out of your crypto assets is to bridge them to a Layer 2 (L2) network.
