ZkSync

• ZkSync is a scaling solution for Ethereum that is live on mainnet. zkSync is a trustless protocol for scalable low-cost payments on Ethereum, powered by zkRollup technology. It uses zero-knowledge proofs and on-chain data availability to keep users' funds as safe as though they never left the mainnet.

• zkSync for Developers

zkSync features

• Mainnet-level security with zero reliance on 3rd parties
• ETH and ERC20 token transfers with instant confirmations and 10-minute finality on L1
• Ultra-low transaction fees (~1/100th of mainnet costs for ERC20 tokens and ~1/30th for ETH transfers)
• No registration is required to receive funds
• Payments to existing Ethereum addresses (including smart-contracts)
• Fees conveniently payable in the token being transferred
• Withdrawals to mainnet in ~10 minutes

Description of work:

Users can also deposit ERC20 tokens into ZkSync. In this Bounties we want to review and analyze the following:

• Which ERC20 tokens have been deposited the most volume ($) in the last 60 days
• Which ERC20 tokens have been deposited the most (in total count) in the last 60 days

Note

• We use the [ethereum] schema and [ez_token_transfers] table
• zkSync Contract Address is 0xabea9132b05a70803a4e85094fd0e1800777fbef

1 ---> Top 10 ERC20 tokens have been deposited the most volume

To do this, we sum(amount) and sum(amount_usd) for each symbol, provided that:

• origin_to_address = '0xabea9132b05a70803a4e85094fd0e1800777fbef' ---> zkSync Contract Address
• block_timestamp::date >= current_date - 60 ---> In the last 60 days

According to the results, it can be seen that:

• It can be seen that stablecoins have more volume. This could be due to market downturns as users try to convert their assets to stablecoins to save capital.
• The USDC token with 27840152.589960 has the highest volume compared to other tokens. It accounts for approximately 41.83% of the total volume
• In the next are WBTC with volume 18448538.2926417 (27.71% of total) and USDT with volume 12114527.9938195 (18.2% of total).

2 ---> Top 10 ERC20 tokens have been deposited the most count

To do this, we count(tx_hash) for each symbol, provided that:

• origin_to_address = '0xabea9132b05a70803a4e85094fd0e1800777fbef' ---> zkSync Contract Address
• block_timestamp::date >= current_date - 60 ---> In the last 60 days

According to the results, it can be seen that:

• The USDC token with 3374 (31.94% of total count) has the highest number of transactions compared to other tokens. In the next are STORJ with 2516 (23.82% of total count) and LDO with 1524 (14.42% of total count).
