1. zkBob project security

why the project can be called safe?

• zkBob Contracts Security Audited: On January 5, 2023, ChainSecurity released its final audit report covering the zkBobPool, BobToken and BobVault contracts. (docs.zkbob.com/resources/security-audit))

• Risks for users are reduced due to limits on deposits and withdrawals. In addition, there are restrictions on adding their tokens to the pool so that people cannot have much influence on liquidity and they can't use it to their own advantage. Also, such restrictions are set to protect against large deposits and withdrawals that may be the result of illegal activities (for example, hacking, when attackers need to quickly transfer a large amount of funds) (docs.zkbob.com/zkbob-overview/compliance-and-security))

(docs.zkbob.com/zkbob-overview/deposit-and-withdrawal-limits))

2. What protocols and what kind of protocols does zkBob use?

• TRM Labs Integration, provides risk management & compliance protocols for detecting & preventing illegal financial activity. Used by Circle (USDC), Binance & others for AML/CFT compliance. zkBob integrated with TRM to prevent criminal funds entering the privacy pool. Wallets are screened for prior high-risk/suspicious behavior, like transactions with hacked/sanctioned addresses or dark web involvement. Addresses with suspect activities can't connect or deposit into zkBob, ensuring a safe & secure transfer environment. Withdrawals to suspicious addresses are also blocked. (docs.zkbob.com/zkbob-overview/compliance-and-security/trm-labs-integration))

• zkSNARKs technology, are a special technology for private transactions. It has two verifiers:

1. Transmission verifier: Verifies the correctness of the transaction. User generates proof for deposit, transfer or withdrawal. The verifier asks, "Is the user allowed to do this?"

2. Tree verifier: ensures that the merkle tree is updated correctly. The proof of the transaction is in the right place. The verifier asks, "Is the merkle tree updated correctly?"

Simply put, zkBob uses zkSNARK to ensure transaction confidentiality, and verifiers verify that transactions are correct and that the merkle tree is updated correctly.

3. Is it safe to connect my main wallets to the site and send money from multiple wallets to 1 zkBob account?

Yes, it's safe.

• With zkBob, your information remains secure and private. Transactions use zkproofs, so no specific details like sender, receiver, or amount are recorded, making it impossible to link them within zkBob. (docs.zkbob.com/zkbob-overview/faq#i-made-deposits-to-1-zkaccount-from-multiple-0x-addresses.-is-information-tying-these-deposits-to-a))

• zkBob doesn't link your accounts to its contract. Only the deposit amount of BOB is visible, not zkAccount details. Thanks to the zk proving mechanisms, no one public record shows which zkAccount received the funds in zkBob. (docs.zkbob.com/zkbob-overview/faq#can-the-zkbob-application-be-compromised-and-my-information-made-available))

4. Will your accounts be considered suspicious, as was the case with Tornado cash?

No, because zkBob ensures it doesn't accept money from suspicious wallets or dirty cryptocurrency that may violate the law. Your wallet won't be considered suspicious or flagged like was with Tornado cash. zkBob keeps things clean and secure!
