Deposit weETH for miweETH

Now that you have some weETH (or eETH), let's deposit them into Mitosis. Go to the Expedition Campaign website and follow the Deposit UI. The minimum deposit amount is 0.001 weETH (or eETH) per transaction.

Expedition (weETH) supports the following networks:

  1. Ethereum (Chain ID: 1)
  2. Arbitrum (Chain ID: 42161)
  3. Scroll (Chain ID: 534352)
  4. Mode (Chain ID: 34443)
  5. Blast (Chain ID: 238)
  6. Linea (Chain ID: 59144)
  7. Optimism (Chain ID: 10)
  8. Manta (Chain ID: 169)

Depositing in the Ethereum network:

When you submit your transaction, Mitosis wraps your eETH into weETH before depositing it into the Mitosis Vault smart contract on Ethereum. Be sure to import miweETH into your wallet at the end of the transaction. Now you have miweETH on Ethereum.

For L2 networks:

You can deposit your Ethereum weETH (or eETH) into one of the Arbitrum network via the Expedition app. Simply follow the same UI and choose the Arbitrum network. Mitosis wraps your eETH and bridges weETH to the Arbitrum network. As you did on Ethereum, ensure you import miweETH on your wallet (you only have to do this once per network). Now you have miweETH on the Arbitrum network.


You need to have weETH on L2 networks, where weETH exists as OFT, already to deposit on those networks. If you have weETH on Ethereum, you will not be able to deposit on those networks directly on the Expedition app.

Please note

Mitosis utilizes its proprietary batching solution to securely and efficiently bridge LP assets. In other words, actual bridging occurs only when Mitosis periodically executes the bridging transactions.


Mitosis executes the Refund transaction when your submitted deposit amount exceeds the remaining room for the current Epoch. There are two types of Refund transactions.

  1. 100% Refund: Mitosis sends you back the entire deposit amount
  2. Partial Refund: Mitosis deposits the maximum available amount and sends you back the remaining amount. Please note that the refunded amount will be in the form of weETH (Refund amount = weETH amount - minted miweETH amount)

Please note

Mitosis wraps your eETH to weETH using the Ether.Fi wrapping contract if you deposit eETH. The refunded weETH amount can be different from your deposited eETH amount due to the conversion rate between eETH and weETH at the time of the Refund transaction.
