Parsing and collecting public wallets from CEX (Etherscan + L2)

Brief: need to compile a database of all publicly available (tagged/identified) wallets of centralized exchanges (CEX) in the Ethereum ecosystem and popular L2s (Arbitrum, Optimism, Base, zkSync, Polygon, etc.). The result is a clean deduplicated list
Mandatory tasks for the executor

Data Collection

1. Parse Etherscan/Arbiscan/Optimism Explorer/Base Explorer/zkSync Explorer/Polygonscan and similar (where applicable) to obtain addresses tagged as exchange (tags/labels), as well as publicly published deposit addresses from verified contracts/exchange pages.

2. Use official APIs (Etherscan API, etc.) and/or web-scraping where APIs do not provide the necessary tags.

3. Collect addresses explicitly marked as belonging to CEX (e.g., “Binance 1”, “Huobi Deposit”, “Coinbase Custody”, etc.).

Identification and Validation

1. For each address, record: network, address, label, exchange name (if available)

Outputs / Formats

• Main output: .xlsx and .csv with columns (at minimum):

  • address (checksum)

  • network (ethereum/arbitrum/optimism/base/zkSync/polygon/…)

  • exchange_name (if defined)

If there is a ready-made solution - very good.
