![]() ![]() To start storing Optimistic Ethereum tokens in your wallet, you’ll first need to bridge your Ethereum ERC20 tokens to Optimistic Ethereum. Click “ Save“, and you’ll be automatically connected to the Optimistic Ethereum network.Īlternatively, to integrate Optimistic Ethereum automatically, head across to Chainlink’s page for Optimistic Ethereum using the link, then simply choose to “ Connect“, and then approve the changes in MetaMask.If Optimism is not appearing on your list, choose “ Add Network“.Click onto the dropdown “ Ethereum Mainnet” at the top of the wallet.If you are using Metamask and it’s not yet available from your network list, follow the steps below to add Optimistic Ethereum to your Metamask account. Note: If there is a problem with the bridge you can also use the Etherscan Message Relayer as a backup mechanism to claim withdrawals.To connect Optimism to MetaMask, you’ll first need to have a wallet that supports and connects to Optimistic Ethereum. In this way, Optimism possesses all of the benefits of the leading blockchain Ethereum, such as decentralization and security, without high gas fees and slow execution. It is a roll-up scalable solution for Ethereum, which is a Layer 1 blockchain. Optimism is an Optimistic Roll-up, a fancy way of describing a blockchain that piggybacks off another parent blockchain’s security. Once the challenge period is over, the status in the gateway changes to Claim. Optimism was built by Ethereum developers Jinglan Wang, Karl Floersch, and Kevin Ho. Click the L1 State Root Submission Tx to see when the transaction was written to Ethereum. You can search for the transaction hash on Optimistic Etherscan. If the withdrawal is ready to be claimed, the Execute button will be enabled. Search the transaction hash on the Etherscan message relayer. This shows you the list of recent withdrawals and their status: There are several ways to see if your withdrawal is ready to be claimed:īrowse to the gateway and click your address in the top right corner. While waiting the verification challenge period Normally transactions are published on Ethereum quickly, but in the case of an outage it might take longer, in which case it will take longer until you can claim your withdrawal.Ĭlick Connect Wallet, select your wallet type, and approve the connection in the wallet itself if asked.Ĭlick the check boxes and accept the withdrawal: Wait the verification challenge period, which is seven days from the time the transaction is published on Ethereum. Withdrawals through the Optimism Gateway is a multi-step process: In almost all cases you would be better served by using a third party bridge. The Optimism Gateway is trustless, which requires it to be slow and expensive. Note that this is not the preferred solution. The cost of the merkle proof required for a withdrawal transaction is spread over a larger pool of tokens, so the relative cost of the withdrawal is smaller. Bridges run their own verification so it's not a big risk for them. Over the course of the next month, the Optimistic Ethereum community is invited to nominate projects that they believe should receive a portion of this funding. The bridge takes the risk that the block with the transaction (or a prior one) is invalid. You don't have to wait the normal challenge verification period. This way: The way this works is that the bridge loans you the relevant asset on the Ethereum mainnet. When the bridge gets low on the asset in the Ethereum mainnet, it sends all of those tokens from Optimism to Ethereum in one gateway transaction. Those bridges are usually cheaper and faster than our main gateway, but have a more limited list of supported tokens. We have a list of supported ERC-20 tokens, but you are not limited to them, you can select any token that exists on both Ethereum mainnet and Optimism mainnet. There are two ways to withdraw assets from Optimism: Verify that the centralized exchange is supporting Optimism and that it looks at the Optimism account before you send it anything. ![]() As a result, assets transferred directly to a centralized exchange that doesn't support Optimism are irrevocably lost, unless the exchange can help you. By default, this is an Ethereum mainnet address and the exchange does not look at this address in Optimism. When you transfer assets to a centralized exchange you send it to an address provided by that centralized exchange. ![]()
