7 questions to master the basics of zkSync

Q: Will there be tokens?

Yes

Q: When will the token be issued?

The focus of the team is working on the scalability of Ethereum. You can find any announcements from zkSync on Discord

Q: Why is the fee so high

Our fees are determined by Ethereum Layer 1 (L1) gas prices, because for every zkSync Layer 2 (L2) transaction, we publish relevant data in Layer 1 - this allows us to inherit the security of Ethereum sex.

Q: How long is the withdrawal time?

During the peak period of zkSync usage, the withdrawal time is about 10 minutes. During periods of lower usage, it may take up to 7 hours. Currently, withdrawal times depend on activity on zkSync when we finalize blocks and commit them to L1.

Q: I withdrew my funds but don't see them in my L1 account

If your withdrawal is marked as "Completed" on zkScan , but the funds have not reached your wallet, you should take the following steps:

1. Make sure enough time has passed. Withdrawals take anywhere from 10 minutes to 7 hours, depending on zkSync network usage. Check your transactions in "Internal Txns" on Etherscan 1. Open Etherscan and go to your address page. 2. Go to "Internal Txns." 3. You』ll find a list of all transactions from smart contracts. 4. The list should have your transaction coming from the zkSync smart contract.

2. If the account balance is different than on Etherscan, please contact your wallet support. Depending on your wallet, you may need to add this token for it to appear. If none of the steps above helped you, please email us at [email protected] describing your problem. It must contain the following information: Your zkSync wallet address. The wallet you are using (for example, Trust). When you encounter a problem, the more information you provide, the faster we can solve your problem! I use "Transfer" instead of "Withdraw" to transfer funds to L1

If you are trying to withdraw your zkSync funds to L1, but using the "Transfer" option instead of the "Withdraw" option, you should try to log into zkSync using the wallet that received the funds.

If you are unable to log into your zkSync wallet, you can use the Alternative Withdraw tool.

Q: What is the account activation fee?

The account activation fee is a one-time fee for registering an account with zkSync. This fee only applies to your first zkSync transaction.

On a deeper level, in order to be more suitable for zero-knowledge proofs, zkSync accounts are defined on a different elliptic curve than Ethereum. Activating your account generates and publishes a new private-public key pair on this curve associated with your Ethereum address.

The registration process happens directly on the Ethereum smart contract, so it is an L1 transaction, so the activation fee is paid to the Ethereum miners and not the zkSync validators. ERC-1271 compatible wallets such as Argent add this one-time fee due to higher interactivity with zkSync smart contracts. This operation will be cheaper if you use a wallet based on the CREATE2 smart contract.

Q: What is the difference between Initiated, Committed and Verified on zkScan?

Initiated:: The zkSync server has received and processed the transaction. If the transaction is a transfer, it can be used immediately.

Committed: The transaction appears in a block that has been committed to the L1 smart contract.

Verified: The block of the transaction has been proven and verified on the L1 smart contract.
