Understanding Security Issues in the NFT Ecosystem

The dataset used in the ACM CCS 2022 paper titled "Understanding Security Issues in the NFT Ecosystem". It contains the following items.

• The asset (e.g., collection name, asset URI, metadata URI, etc.) and event (e.g., mint, buy, sell, auction creation, placing of a bid, acceptance of a bid, transfer, etc.) data collected from the top 8 NFT marketplaces (OpenSea, Axie, CryptoPunks, Rarible, Superrare, Sorare, Foundation, and Nifty) are stored in their respective databases. Since the OpenSea dataset contains events for the same set of assets, crawled three times, with a three-month interval between two subsequent crawls: in June 2021, September 2021, and finally in December 2021, therefore respective asset tables are appropriately timestamped.

• The `coins` database contains the Historical prices of the cryptocoins as provided by CoinGecko.

• The `stats` database contains the availability of the source code of the token contracts in Etherscan.

Usage

1. Download all the parts of the dataset zip.
2. Combine them into one single zip file. The MD5 hash of the resulting `nft-marketplaces.zip` would be `2e27cd3a319d0fb187a1a51589156e96`.

   cat nft-marketplaces.zip.part* > nft-marketplaces.zip

3. Extract the zip file containing the database dumps.

   unzip nft-marketplaces.zip

4. Restore databases to a PostgreSQL instance:

   pg_restore -U $DB_USER -h $DB_HOST -v -Fc -Fd -C -d postgres -j $CONCURRENCY $DB_DIR > $LOG_DIR/pg_$DB.log 2>&1

   Substitute variables with appropriate values. $DB_DIR is the directory containing the database backup files. $LOG_DIR is the directory containing the restoration logs.
