Deprecation Guide

Deprecation Notice

Nucleus protocol is formally deprecated as of 12/19/2025.

Once the frontend is deprecated, the user interface for withdraws will no longer exist. However, the vault as a permissionless protocol will always allow you to withdraw through smart contract interactions. For those who do not have a technical experience, using a block explorer is sufficient and this guide will provide a step by step walk through.

Step 1: Identify available assets in the vault

You can use any blockchain explorers available to check assets that are still remaining within the vault. This is an example using the tETH vault on etherscan.

• Here, you can see that WETH, weETH, pufETH are the available assets that exist inside the tETH vault.

• You may decide to choose any asset that exists inside the vault as a withdraw asset. You will specify this token in Step 3.

Step 2: Get your vault token balance

For this section, please refer to the Deployed Assets section for finding the right contract addresses.

Go to a block explorer's page for the given vault token address. Then query the total amount of vault tokens you have using the balanceOf function.

• You can see we are looking at the tETH address, and using the balanceOf function. Pass in your wallet address as the input. This address has 0.120759094314511387 tETH tokens.

Step 3: Withdraw from the vault

Lastly, go to a block explorer's page for the given Teller address and go to the "Write Contract" tab and find the bulkWithdraw function.

• Connect your wallet to the block explorer using the "Connect to Web3" button.

• For the withdrawAsset, input an address of the asset that you found in step one. Here, it is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 which is the WETH token address.

• For shareAmount, input the amount returned from step 2.

• For minimumAssets, input zero.

• For to address, make sure this is your wallet address. The withdrawn funds will be sent to this address.

• Once you press the "Write" button, you will be prompted for a transaction signature. Once the transaction is complete, you will see that your vault token was burned and that you received the underlying asset.

That's it! Thank you for having been a user of Nucleus.
