Help test zkBob on Nile and get rewarded!

zkBob is an open-source non-custodial smart contract wallet with an integrated private payment feature. The protocol operates as a public utility and the protocol itself DOESN’T impose any fees. However, network (gas) fees are charged, and these vary based on the specific network. Network fees are applicable to users for actions such as deposits, withdrawals, and transfers within the zkBob wallet application.

The wallet is already live and has been working in production on Polygon and Optimism for over a year. It has steady usage and transactional volume and currently holds over $500k in assets.

Detailed analytics for all three currently live zkBob pools can be found below:

That’s really interesting.

I did not know any project with zero Knowledge of TRON so far.

I graduated from the zkDAO and I know a bit even technically I will be happy to help.

  1. BOB is 1:1 on USD, you use it from now on, or only USDC?
  2. It’s like having a pool of stablecoin and you own an amount from the pool and inside the pool transfers are hidden only interaction as deposits and withdrawals can be seen but not associated so I can withdraw to any address and never go back to the initial address?
  3. Did you find a solution for the situation where they find and match the transactions due to the
    amount value? The transfer inside option seems to be a way.



The contract for ERC20/TRC20 remains although vulnerable as they USDT holder can block the transfer?

You can deploy also on the base token?

Love it that all is open source :heart_eyes: although the relay is centralized I think that it compasate it through open source!!

Congratulations, keep on building


Hi @constantinpricope201 and thanks for your response!

Let us answer your questions:

  1. Currently, zkBob supports ETH (Optimism pool) and USDC (Optimism and Polygon pools) tokens only. More details can be found on our Dune dashboard
  2. All transactions within zkBob ensure complete privacy, with no disclosure of information about the amount, recipient, or senders, although this data will be stored on the blockchain. For deposits, the amount and sender are publicly available as plain text on the blockchain. Similarly, for withdrawals, the amount and recipient are also publicly available as plain text on the blockchain. More information can be found in our doc on the following section
  3. For enhanced privacy, consider leaving your assets in a zkBob pool for a duration before withdrawal. This way, researchers won’t be able to link two distinct addresses based on transaction amounts. Additionally, you can withdraw assets from your zkBob account in an amount different from the initial deposit. You can read more about privacy in the following section
